The Best Times to Water Your Lawn and Garden: A Seasonal Irrigation Guide for Central New York

Proper watering is the lifeblood of a healthy landscape. In Central New York, where we experience everything from snowy winters to hot, dry summers, knowing when and how to water your lawn and garden is key. This seasonal irrigation guide will help you keep your grass green, garden beds blooming, and trees and shrubs thriving year-round. Whether you’re a homeowner or manage a commercial property, these tips will ensure every inch of your landscape – from expansive lawns to petite planter boxes – gets the moisture it needs at the right time. (At KLM Landscaping, we provide comprehensive landscaping services – including irrigation, lawn care, and seasonal cleanups – to support Central NY properties through all four seasons.)

Spring: Setting the Stage for Growth

As the snow melts and days grow longer, spring in Central NY marks the start of the growing season. Soil is often moist from winter precipitation, but spring weather can be unpredictable – alternating between April showers and dry, windy days. The goal in spring is to prepare your landscape for vigorous growth by providing water when needed and setting up systems for the months ahead. Early morning is generally the best time to water in spring (and throughout the year) so that plants drink up moisture before the day warms. Here’s how to handle spring watering for different parts of your property:

Lawns in Spring

In early spring, your lawn may not need much extra watering thanks to snowmelt and rainfall. Avoid overwatering when the ground is still thawing and soggy; grass roots can suffocate in waterlogged soil. Monitor rainfall: established lawns typically need about 1 inch of water per week during the growing season, and in spring nature often provides a good portion of that. If you experience an unusually dry spring or warm spells, water the lawn deeply once or twice a week as needed rather than daily light sprinklings. Deep watering encourages roots to grow downwards for better resilience in summer. Always aim to water in the morning (between about 5am and 10am) so the grass blades dry out by evening – this helps prevent fungal diseases that can take hold in cool, damp nights.

It’s also time to get your sprinkler system started for the year. If you have an irrigation system, test it in spring to ensure all sprinkler heads and drip lines are working after winter. This is a perfect time for a professional spring startup as part of seasonal irrigation maintenance. (Our Irrigation & Drainage team can help inspect and re-calibrate your sprinklers in spring to make sure every corner of your lawn gets adequate coverage.) And don’t forget: a proper spring cleanup is important before you begin regular watering. Raking up leftover leaves and debris (spring cleanup services) will allow water to reach the soil and grass roots more easily, and it freshens your lawn for the new season.

Garden Beds in Spring

Your flower and vegetable beds are waking up in spring. Perennials start to emerge, and you might be planting cool-season annuals or prepping vegetable plots. Early in the season, the soil often stays damp longer, so you may only need to water new plantings or if you notice wilting. Check soil moisture a few inches down; if it’s dry to the touch at root level, it’s time to water. Water garden beds in the morning so foliage can dry during the day. For new seeds or seedlings, keep the topsoil consistently moist (you may need to water lightly every day or two for seeds to germinate). For established plants, a deep watering once or twice a week is usually sufficient in spring, depending on rainfall.

Spring is also ideal for adding fresh mulch to your garden beds. A couple of inches of mulch will help the soil retain moisture and reduce how often you need to water. (Mulching is often part of a spring bed prep – something we handle during a spring cleanup or planting service.) If you’re unsure how much to water certain plants, pay attention to how they respond: spring bloomers like tulips and daffodils generally don’t need extra watering if spring rains are normal, whereas new transplants (like that rose bush you just planted) will need regular drinks to establish roots. By late spring, as temperatures climb, be ready to increase watering frequency a bit, and consider setting up soaker hoses or drip irrigation in your beds for efficient moisture delivery right to the roots.

Trees in Spring

Your trees, especially large established ones, have deep root systems and often get by with the water nature provides in spring. However, newly planted or young trees (planted within the last 1-3 years) will benefit from consistent watering as the weather warms. After planting a new tree in spring, water it deeply at least once a week (more often if the weather turns hot and dry). Pour water slowly at the tree’s base and around the drip line (the area under the outer canopy) to ensure the root zone gets soaked. Early spring soil can be very moist, so wait until it dries a bit before the first watering. As buds break and leaves start growing, that’s a cue that the tree is active and will use water.

For existing trees, observe if they had any winter damage or dry soil around them. Evergreen trees (like pines or spruces) will start their growth and might need a deep watering in late spring if rainfall has been scarce. Always water trees in the morning when possible. A useful tip: remove any trunk wraps or burlap from winter and check the soil moisture weekly. If the top few inches under the mulch are dry, give the tree a good soak. Spring is about striking a balance – enough water to jump-start growth, but not so much that roots sit in cold, oversaturated ground. As the season progresses, watering needs will gradually increase for young trees, preparing them for the hotter months ahead.

Shrubs in Spring

Shrubs are the backbone of many landscapes, and spring is when they put out new leaves and blooms. Many deciduous shrubs (those that lost leaves in winter) won’t need much supplemental watering in early spring beyond rainfall. However, keep an eye on any flowering shrubs like azaleas, rhododendrons, or lilacs – as they develop buds and flowers, consistent moisture helps them bloom their best. Ensure the soil around shrubs is moist but not waterlogged. Just like with other plants, morning watering is ideal if needed. Check soil moisture by hand: if the soil 3-4 inches down is dry, it’s time to water. Aim the hose at the base of the shrub, not on the leaves, to avoid encouraging disease.

Evergreen shrubs (e.g., boxwoods, hollies) come out of winter with some dehydration. If spring rain is sparse, give them a deep watering in the early spring and then weekly or biweekly as needed. When planting new shrubs in spring, water them thoroughly right after planting and keep the soil evenly moist for the first several weeks as they establish roots. Adding a layer of mulch around shrubs (while keeping mulch a couple of inches away from the stems) will help keep the soil damp and cool. By mid-spring, you may find yourself watering new or shallow-rooted shrubs about once a week. Just be careful not to overdo it in cool weather – soggy roots can be just as harmful as dry roots. Strike that spring balance and your shrubs will reward you with healthy foliage and flowers.

Planter Boxes in Spring

Planter boxes and container gardens often get a head start in spring – you might plant pansies or early herbs in pots as soon as the last frost passes. Keep in mind that containers dry out faster than ground soil, especially as the sun’s intensity increases later in spring. In the cool early spring, your planter boxes may only need watering every few days. But once you plant up spring containers, check them daily. Feel the potting mix an inch or two down; if it’s dry, give the planter a drink. Mornings are the best time to water planters as well, so plants are well-hydrated for the day’s growth and any excess moisture can evaporate off foliage. If a sudden hot spell hits in late spring (which isn’t unheard of in Central NY), you may even need to water small planters twice in a day – morning and late afternoon – to keep the soil moist.

Using good-quality potting mix with water-retaining ingredients, and adding a top layer of mulch or moss, can help container soil stay moist longer. Also, be sure your planters have drainage holes; spring rains can easily waterlog a planter box if water can’t drain out, drowning the roots. If you manage planters for a commercial property (for example, flower boxes at a storefront or patio planters at an office), establish a routine to water them before business hours begin. Consistent attention in spring will set your container flowers and ornamental plants off to a strong start. (For more planting and watering tips, you can also see our Planting Guide for Beginners, which covers how to care for new plants.)

Summer: Consistent Hydration in the Heat

Summer in Central New York brings warm temperatures, periods of intense sun, and sometimes less frequent rainfalls (punctuated by the occasional thunderstorm downpour). During the hot summer months, consistent hydration is critical for your lawn and garden. However, timing and technique matter – watering during the wrong part of the day can lead to water waste or plant stress. In summer, always aim to water early in the morning, ideally between 5am and 9am. This ensures water soaks into the soil with minimal evaporation and gives plants a reserve of moisture before the day’s heat. If morning watering isn’t possible, late afternoon (around 4-6pm) is a second-best option – early enough that leaves can dry before nightfall. Avoid midday watering under the scorching sun (much of the water will evaporate or even scorch sensitive leaves) and avoid late-night watering (sitting water overnight invites fungus). Let’s break down summer irrigation needs by area:

Lawns in Summer

Your lawn usually needs the most attention in summer. During peak growing season with high evaporation, turf grass benefits from about 1 to 2 inches of water per week (including rain) to stay green and healthy. In practice, this might mean running sprinklers or watering about 2-3 times per week, delivering roughly 1/2 inch each time. Deep, infrequent watering is better than shallow daily sprinkling – you want the water to penetrate 6-8 inches into the soil to encourage deep roots. For example, instead of watering a little every day, you might water for a longer duration every three days. The exception is newly seeded or freshly laid sod lawns, which do need lighter, more frequent watering multiple times a day initially; once established, scale back to the deep watering schedule.

Morning watering is non-negotiable in summer – a predawn or early morning soak keeps your lawn hydrated and helps it cope with midday heat. If you have an automatic irrigation system, set it to run just before sunrise. Also, be mindful of any local watering restrictions (some communities implement alternating day schedules for watering during droughts). If your lawn starts to look dull or slightly gray-blue, that’s a sign it’s thirsty and you should water that day. Conversely, if we get a good soaking thunderstorm, you can skip your scheduled irrigation – too much water can be as harmful as too little, promoting shallow roots or fungus.

For both residential and commercial lawns, proper summer watering paired with good maintenance is key. Mow your grass a bit higher in summer (3-4 inches) to shade the soil and reduce evaporation. Lawns will naturally slow down in extreme heat; some cool-season grasses may even go dormant and turn brown if not watered. It’s okay to let a lawn go semi-dormant to conserve water (it will green up again when cooler, wetter weather returns), but if you want a lush green carpet all summer, consistent watering is a must. Our Lawn Care experts often include summer watering advice in our maintenance plans, ensuring that turf on both home lawns and large commercial campuses stays vibrant without wasting water.

Garden Beds in Summer

Summer heat can be tough on garden beds full of flowers and vegetables. By now, many annuals and perennials are mature and possibly flowering or producing fruit, which means high water demand. Check your garden beds daily in summer. When the top 2 inches of soil are dry, it’s time to water. Most garden beds benefit from a deep watering about 2 times a week, but vegetables (especially in raised beds) and any moisture-loving flowers might need water every other day during heat waves. Morning is the best time to water gardens in summer; the plants will be able to take up moisture to get through the day, and any wet foliage will dry out, reducing the risk of mildew or fungus (which can be rampant in the humidity of a New York summer).

How you water is also important. Using a soaker hose or drip irrigation in garden beds is ideal – it delivers water right to the soil and roots with minimal evaporation. Plus, keeping foliage dry by watering at soil level helps prevent disease. If you hand-water with a hose or watering can, aim for the base of the plants. A good practice is to water slowly and deeply – you want the water to sink at least 6 inches down. You might water for 20-30 minutes per section with a sprinkler or a few minutes per plant with a hose, rather than a quick sprinkle that only wets the surface. Mulching is your best friend in summer: if you haven’t already, ensure you have 2-3 inches of mulch on garden beds to lock in soil moisture and keep roots cooler. This can drastically reduce how often you need to water and help your plants handle the heat.

Pay special attention to vegetable gardens, as consistent moisture is critical for crops like tomatoes, cucumbers, and peppers (inconsistent watering can lead to problems like blossom end rot in tomatoes). If you grow vegetables, try not to let the soil completely dry out between waterings – keep it evenly moist. On the flip side, don’t keep beds constantly soaked either; most plants need that brief drier period between waterings to breathe. In the height of summer, wilting in late afternoon is a common sight even in well-watered plants – often it’s just heat stress and they’ll perk up by evening. If they’re still droopy by next morning, that’s when you know they truly need more water. By being attentive and watering effectively, your summer garden beds will flourish with colorful blooms and a bountiful harvest.

Trees in Summer

Established trees are more drought-tolerant than lawns or flowers, but prolonged summer dryness can still stress them (and large trees can drink a lot of water!). Generally, big shade trees with extensive roots may only need supplemental watering during extended dry spells. But younger trees and ornamentals should be watered during hot, dry periods. A good rule in summer is to water trees deeply once every 1-2 weeks if there’s no substantial rainfall. Rather than frequent shallow sprinkling, use a slow trickle from a hose or soaker hose at the tree’s drip line (the circumference of its canopy) for an hour or more – this ensures water soaks down to the deeper roots. You want to wet the soil at least 8-12 inches deep for trees. Early morning or evening is fine for trees since ground evaporation is your main concern (their leaves are high up and less prone to fungal issues than a lawn).

For young trees (planted this season or last year), water more often – about 5 gallons of water per inch of trunk diameter per week is a common guideline. So a new tree with a 2-inch trunk might need ~10 gallons weekly, split across two waterings (5 gallons twice a week, for instance). You can circle a slow-running hose around the base for several minutes to achieve this. Watch for signs of drought stress in your trees: wilting or curling leaves, or browning at the edges, can indicate thirst. Certain trees like birch, dogwood, and maple prefer steadier moisture and may suffer in drought, so give them attention when rain is scarce.

If you have trees in commercial settings (like lining a corporate office entry or in a parking lot island), remember that heat radiating off pavement can dry their soil quicker. Those might need extra water despite their “tough” appearance. Also, summer storms – while they dump water – often have runoff if rain comes down too fast. Don’t assume a thunderstorm fully watered your trees; check the soil a day or two later. If it’s dry a few inches down, the trees might still need a soak. By taking care of your trees in summer, you ensure they stay strong and healthy, providing shade and beauty for years to come.

Shrubs in Summer

Many shrubs, like trees, can tolerate short dry periods, but to keep them lush and flowering (for those that bloom in summer), you’ll want to water them during hot spells. Flowering shrubs such as roses, hydrangeas, and spireas often need regular moisture when they’re blooming or forming buds. A wilting hydrangea on a July afternoon is practically a New York postcard – they’re telling you they’re thirsty! In general, check your shrubs’ soil twice a week in summer. If it’s dry 3-4 inches down, give them a thorough watering. Aim to water the base of shrubs using a garden hose or drip line, delivering water slowly so it can soak deep. How often will depend on your soil and the weather, but many shrubs do well with a deep watering (think 15-30 minutes with a hose on a slow flow) once or twice a week in summer heat. Shallow-rooted shrubs or those in sandy soils may need water more frequently (every other day in extreme heat), whereas those in heavier clay soil hold moisture longer.

As with other plants, morning watering is best. If you have an automated irrigation system, make sure your shrub beds are included or consider a drip irrigation extension for them. Be cautious not to hit shrub leaves with water during the hottest part of the day – wet leaves can actually scald in direct sun, and consistently wet foliage invites diseases like powdery mildew. For evergreen shrubs (like juniper, yew, or boxwood), a midsummer deep soak helps them combat the drying effect of heat and summer winds. If you notice evergreen needles or leaves yellowing or browning at the tips, that could be drought stress.

One useful tip: use the “finger test” – stick your finger into the soil near a shrub’s root zone. If it feels dry at root depth, water; if it’s still moist, check again in a day or two. Overwatering can be an issue too, especially for shrubs like lavender or rosemary that prefer it on the dry side. So, find the right balance. With attentive care, your shrubs will stay green, glossy, and possibly reward you with continuous blooms (in the case of reblooming roses or summer-blooming varieties). And remember, healthy, well-watered shrubs are more resilient against summer pests and diseases too.

Planter Boxes in Summer

When it comes to planter boxes and container gardens in summer, one word rules: vigilance. Containers can dry out incredibly fast on hot days, since they have limited soil volume and are often exposed on all sides to sun and wind. It’s not uncommon to need to water planters every single day in summer, and small pots or window boxes in full sun might even require water twice a day during heat waves. As a rule, check planter soil each morning – if the top inch is dry, water thoroughly. By thoroughly, we mean water until you see it start to drain out the bottom of the pot. This ensures all the roots get a drink. Morning is the ideal time, but don’t be surprised if by late afternoon the soil is dry again (especially in hanging baskets or small pots). In that case, an evening top-up (around 4-5pm) can help, just be careful to water the soil and not soak the foliage overnight.

To make container watering easier, consider grouping pots together (they can shade each other a bit and reduce drying) or use self-watering planters that have reservoir systems. In commercial settings – say, planter boxes at a restaurant patio or office entrance – you may even want to install a simple drip irrigation line on a timer to each planter. This way, your beautiful seasonal flowers won’t suffer if the maintenance crew is busy on a hot afternoon. Using a mulch on top of the planter soil (like decorative moss, gravel, or bark chips) can also slow evaporation. Another hack: during extreme heat, move planters into partial shade if possible in the afternoon to give them a break, or at least shield them from hot west exposure.

Be cautious not to overwater containers either – if a pot doesn’t drain well, roots can rot. Ensure drain holes are clear. If you see leaves yellowing or a plant wilting even when the soil is wet, it might be a sign of overwatering (or poor drainage) rather than thirst. Most of the time though, summer wilting in planters is from dryness, and the cure is prompt watering. Your planter boxes filled with petunias, geraniums, herbs, or other annuals will flourish with daily attention. With vibrant planters, you’ll add instant curb appeal to any home or business – just keep that watering can or hose handy as part of your daily summer routine! (Need some inspiration?

Fall: Winding Down and Preparing for Dormancy

Fall in Central New York is a season of transition. Temperatures begin to drop, days get shorter, and rainfall can be quite variable – some autumns are rainy and cool, others are surprisingly dry. Your lawn and plants start slowing their growth in preparation for winter dormancy, but that doesn’t mean you should put the hose away just yet. Fall watering is about helping plants store energy and moisture for the winter and giving any late-season plantings a good start. The key is to gradually adjust your watering frequency downward as temperatures cool. Continue to water in the mornings when you do water, as early-day moisture will be taken up by plants and any excess can evaporate under the gentler fall sun. Let’s look at what needs water during autumn:

Lawns in Fall

Early fall (September into early October) often still requires watering, especially if summer left your lawn a bit dry or if you overseeded your lawn in late summer. In fact, fall is a prime time to repair and overseed lawns, and new grass seed must be kept moist. If you’ve overseeded or fertilized your lawn in early fall, make sure to water lightly every day or two for the first couple of weeks so the seed can germinate and young grass can establish. For established lawns, aim to keep up that ~1 inch per week schedule in early fall if rain is lacking – your grass is actively growing in the cool weather and will benefit from consistent moisture to build strong roots before winter. Morning watering is still best, and you usually won’t need to water as often as in summer due to cooler temps and heavier dews overnight.

As fall progresses and we start getting more rain, you can cut back on supplemental watering. By mid to late October, you’ll typically reduce watering significantly or stop altogether, especially once the lawn has gone mostly dormant and after the first frost. However, don’t quit watering too early if the autumn is dry. A good practice is to give your lawn a deep watering in late fall (early November or just before the ground freezes) if rainfall has been below normal. This late-season watering acts like a goodbye drink that will help the grass roots not dry out over winter. Another crucial fall task is winterizing your irrigation system. Before hard freezes arrive, you’ll want to blow out sprinklers and drain hoses. (Our team can perform this as part of fall irrigation shut-down under our Irrigation & Drainage services – ensuring your pipes and sprinkler heads don’t crack from freezing water.)

Finally, remember that fall is cleanup time too. Keep leaves raked off your lawn – a thick layer of leaves can trap moisture and promote fungus, plus prevent water from reaching the grass roots evenly. (For help getting your yard in shape, consider a fall cleanup. Removing debris, aerating compacted soil, and clearing gutters all contribute to better water absorption and distribution.) By attending to watering in the fall, you’ll set the stage for a healthier lawn next spring. And if you want a detailed checklist of autumn tasks, be sure to read our Fall Cleanup Guide for tips on preparing your landscape for winter.

Garden Beds in Fall

Come fall, your garden beds will start to wind down. Summer annuals will fade, and perennials will start to die back or go dormant. Early fall can still be colorful (think mums, asters, ornamental kale, and late-blooming perennials), and these plants will need regular watering during their prime. If September is warm and doesn’t bring much rain, continue watering flower beds and vegetable gardens as needed – roughly once or twice a week deeply, or more frequently for any still-producing veggies like autumn squash or late tomatoes. As with other seasons, check soil moisture: if the top few inches are dry, water in the morning. By October, cooler weather and morning dew often keep soil moist longer, so you might find you only need to water beds once a week or less.

One important consideration is any fall planting you do. Fall is an excellent time in Central NY to plant trees, shrubs, and perennials because the soil is still warm enough for roots to grow a bit, and cooler air temperatures put less stress on new plants. If you plant or transplant in fall, be sure to water those new additions thoroughly and frequently until the ground freezes. They’ll need to go into winter well-watered to survive. Even established perennials appreciate some water in fall to help their root systems store energy. Watering in early fall can also help soften soil for tasks like bulb planting or dividing plants. Come late fall, once most of your plants have died back or been cut down, you can mostly stop watering garden beds. Let nature take over with rainfall. If an early freeze is coming and the soil is very dry, a final watering can’t hurt – moist soil holds warmth a bit better and can protect roots from freezing too fast.

Also, consider protecting your beds for winter: adding a layer of compost and then a winter mulch (like straw or shredded leaves) after the ground begins to freeze will lock in moisture and moderate soil temperatures. This isn’t “watering” per se, but it conserves the moisture you’ve provided. And don’t forget to empty and store any drip irrigation hoses if you used them, to prevent cracking in cold weather. Overall, fall watering is about tapering off: give plants enough moisture to finish the season strong and enter dormancy without drought stress, but you’ll gradually be doing less and less as the weeks go by.

Trees in Fall

Trees experience a lot of change in fall – deciduous trees change color and drop their leaves, entering dormancy, while evergreens slow their growth but keep their foliage. Watering trees in fall is about timing. In early fall, continue to water as needed, especially if the late summer/early fall period is dry. Trees are actively drawing in water in September to support late-season growth and to store in their tissues for winter. A deep watering every couple of weeks in dry early fall conditions is beneficial. Once trees start dropping leaves (leaf fall often starts in October for many species in Central NY), their water needs decrease since they are essentially shutting down for winter. However, their roots will still absorb water until the ground is frozen, so don’t neglect watering entirely if autumn rains don’t come.

A critical practice is to ensure evergreen trees and shrubs are well-watered before winter. Evergreens (like pines, spruces, firs, arborvitae) don’t lose their needles and will continue to lose moisture through them in winter (a process called transpiration). If the soil is dry when it freezes, evergreens can suffer winter burn (drying out and browning of foliage). To prevent this, water your evergreens deeply in the fall – ideally in October and even early November if the weather permits – to charge the soil with moisture. We often recommend giving all your trees (deciduous and evergreen) a good soaking late in the fall, before the first hard freeze. Pick a day when temperatures are above freezing and water the area around each tree’s root zone thoroughly. This might be your last watering until spring.

By mid to late fall, you should also be preparing any irrigation that serves trees for winter (blowing out drip lines around trees, etc.). Also, remove any tree watering stakes or gator bags you might have used in summer on young trees to avoid them freezing and splitting. In summary, early fall: water if needed; mid fall: taper off for deciduous trees but keep evergreens watered; late fall: one final deep watering for all, especially evergreens. Your trees will then enter winter dormancy in good shape, with a moisture reserve to draw from on those occasional warm winter days.

Shrubs in Fall

Shrubs follow a similar pattern to trees in fall. Deciduous shrubs (those that drop leaves, e.g., hydrangeas, lilacs, viburnums) will need regular watering in early fall if conditions are dry, particularly if they had a tough time in summer. This helps them recuperate and store energy for the next spring’s growth and blooms. If your fall is seeing weekly rain, you can ease off additional watering. But if you notice wilting or very dry soil around shrub bases in September/early October, give them a drink. Newly planted shrubs in fall should be watered frequently until the ground freezes – usually that means every other day for the first couple of weeks after planting, then twice weekly afterwards, tapering off as the weather gets colder.

For evergreen shrubs (such as boxwood, rhododendron, laurel, and other broadleaf evergreens common in landscapes), ensuring adequate moisture in fall is crucial. Like evergreen trees, these shrubs will face winter winds and sun while their roots are in frozen ground, so they can’t take up water at that time. Water them well through the fall. A good regimen is weekly deep watering in early fall if it’s dry, and at least a couple of deep waterings in October/November for all evergreens. You might notice that broadleaf evergreens like rhododendrons have leaves that droop or curl in very cold weather – that’s a natural response to cold, but having well-hydrated roots going into winter will help them recover come spring.

By late fall, after leaves have dropped and the first frost has hit, you can stop routine watering of most shrubs. Focus on other winter prep tasks: add mulch around the base of shrubs (especially evergreens and shallow-rooted ones) to protect roots and help retain moisture. If you have areas where water pools in fall (from seasonal rain), make sure your shrubs in those spots aren’t sitting in water too long – proper drainage is important year-round to prevent root rot. (If you notice chronic puddles around your landscape each fall, it might be worth exploring drainage solutions like French drains to protect your plants and property.) As autumn ends, your shrubs should be moist from that last fall rain or watering, mulched, and ready to snooze through winter.

Planter Boxes in Fall

By the time fall arrives, many summer planter boxes will have finished their show. Early fall, however, often brings a fresh round of container plantings – think of those beautiful mums, asters, ornamental peppers, or pumpkins and gourds used to decorate front steps and business entrances. If you’ve swapped out summer flowers for fall arrangements, keep watering those planters! Fall days can still be quite warm, and containers will dry out, albeit a bit slower than in July. Water fall planter boxes when the top inch of soil is dry. Mums, for instance, are thirsty plants and may need daily watering during warm early fall days to keep their blooms perky. As always, water in the morning to avoid fungal issues, especially because fall nights get cooler. By mid-fall, you’ll likely water planters every 2-3 days rather than every day, thanks to cooler temps and increased humidity.

One thing to watch with fall containers is overwatering – as the weather cools, containers don’t dry out as fast, so always check the soil before watering. If we get a stretch of rainy days, you might not need to water at all. Good drainage remains important; you don’t want pots sitting in water after heavy autumn rain. If your planters are exposed to rain, you might even tilt them or bring them under cover if an extended wet period is forecast, just so they don’t become waterlogged. Many people start to empty and clean out planters by late fall (after frost has killed off annuals). If you’re done with a planter for the season, you can empty the soil or simply move the planter into a garage or shed to avoid cracks from freezing water. Terra cotta and ceramic pots especially should be sheltered or at least ensure they’re not full of wet soil when a hard freeze hits.

For commercial properties with large planters, fall is a good time to plan ahead: decide if you’ll have winter displays (like evergreen boughs, branches, holiday decor in pots), and if so, remove spent fall plants before the soil freezes. You likely won’t water winter displays (since they’re usually just cut greens), but if you have any live evergreen shrubs in planters that remain outside, give them a final watering in late fall. After that, it’s mostly hands-off until spring. All in all, fall planter care is relatively short-lived but important – a bit of watering and maintenance will keep those autumn mums and decor looking fresh through Halloween and even Thanksgiving. Then it’s time for a well-earned rest for you and your watering can!

Winter: Off-Season Care and Considerations

Winter in Central New York means freezing temperatures, snow cover, and dormancy for lawns and gardens. For the most part, watering outdoors in winter is not needed – and often not possible when the ground is frozen solid. Your focus should shift from active irrigation to protecting your plants and irrigation systems from winter damage. By winter, if you’ve followed good fall practices, your lawn, garden beds, trees, and shrubs should all be well-watered going into the cold season, and your irrigation system should be winterized. There are still a few considerations to keep in mind during winter:

Lawns in Winter

Once the ground freezes (typically by late November or December in Central NY), you should not water your lawn. The grass is dormant or semi-dormant, and adding water will just create ice or runoff. Your lawn will get moisture from the snow that falls, and that’s usually plenty. In fact, a layer of snow can act as insulation for the grass. Avoid any practices that would introduce water to a frozen lawn (for example, don’t leave a hose dripping or anything of that sort). What’s more important is protecting the lawn from physical damage and preparing for spring. Keep foot and vehicle traffic off frozen, dormant grass as much as possible to prevent breaking the brittle blades or compacting the soil. If we have periods of little snow but very cold, dry winds, there isn’t much you need to do – grass can tolerate that dormancy period. It will green up again when temperatures rise and rains return.

One tip: if we get a mid-winter warm spell where temperatures go above 40°F for a week or more and the ground surface thaws, you could give the lawn a light watering especially if it’s a new lawn that was seeded in the fall. This is not commonly needed, but sometimes in an unusually dry winter it can help prevent desiccation of new grass. However, in most cases, you won’t drag out hoses in January. Focus instead on making sure your lawn will get water when it needs it again: this means having your irrigation system ready to restart in spring. Also, if salt is used on driveways or sidewalks adjacent to your lawn (a common necessity in winter), be aware that salt can dry out grass and soil. In early spring, you may need to flush those areas with extra water to leach out salt residues. Many commercial property owners use our Snow & Ice Removal services to clear lots and walks – we do so carefully to minimize salt damage to landscape, but it’s something to keep in mind for lawn health. For now, let winter run its course, and your lawn will rest and rejuvenate beneath that snow blanket.

Garden Beds in Winter

Your garden beds will largely be in hibernation during winter. Perennial plants have died back, bulbs are resting underground, and any bare soil or mulch might be covered by snow. There is no need to water garden beds in winter – in fact, you couldn’t effectively do so if you tried, because frozen soil won’t absorb water. Natural precipitation (snow and occasional rain or sleet) will provide moisture that slowly soaks in during thaws. The best thing you can do for garden beds in winter was likely done in fall: applying a winter mulch after the ground freezes helps lock in moisture around root zones and protects plants from freeze-thaw heaving. If you did that, your plants are as prepared as they can be. If not, and if the ground is not yet fully frozen, you could still add a layer of mulch on a milder winter day to help moderate soil conditions.

In some cases, people have winter vegetable gardens (like cold frames or hoop houses) or winter-hardy plants like garlic in the ground. Those might need the occasional watering during a prolonged dry mild spell, but those are specialty situations. The typical residential or commercial landscape won’t have anything growing that needs water in mid-winter. Houseplants and greenhouse plants are another story, but that’s outside our outdoor landscape focus here. One note on broadleaf evergreens in beds (for example, rhododendrons or mountain laurel in a foundation bed): these can get winter burn from sun and wind. You can’t water frozen soil to help them, but you can spray anti-desiccant on the leaves in late fall or put up burlap screens to break
