Winter Watering Newly Planted Trees in Ohio

Every January I drive past a few of the trees I planted the previous fall and check on them. The October installs are usually fine. The ones I lose, when I lose any, are almost always the trees the homeowner forgot to water once the calendar flipped to November. People assume the rain and snow handles it. In Central Ohio, with our freeze-thaw cycles and dry stretches between snows, it often does not.

This is what I tell every client who put in a new tree in 2026, and what I want any Ohio homeowner with a young tree to do this winter.

Should I water newly planted trees in winter in Ohio?

Yes, anytime the ground is not frozen solid and we have gone more than 10 to 14 days without significant precipitation. A tree planted within the past two years has a root ball that has not yet expanded into the surrounding soil and dries out faster than people realize, especially during the dry, windy stretches we get in January and February. OSU Extension guidance on tree establishment specifically calls out winter watering during dry, mild spells as essential for first-year and second-year plantings.

On a Chillicothe property where we put in three serviceberries last October, I went out the second week of January and watered each tree with five gallons because the previous 16 days had given us less than a quarter-inch of precipitation total. Two weeks later we got a thaw, the trees pushed early buds in late March, and all three leafed out on schedule. The neighbor’s October-planted dogwood, never watered after Thanksgiving, leafed out on one side only.

How much water does a young tree need in winter?

Roughly 10 to 15 gallons per inch of trunk diameter, applied once during any dry, above-freezing stretch of more than two weeks. A typical newly planted 1.5-inch caliper shade tree wants about 15 to 20 gallons per watering event. Smaller ornamentals like a serviceberry or redbud at 1-inch caliper want about 10 gallons.

Apply the water slowly so it actually soaks in rather than running off frozen surface soil. I use a five-gallon bucket with three small holes drilled in the bottom and let it drain over 15 to 20 minutes per tree. A slow trickle from a garden hose works too, if your outdoor spigot is still active.

When during winter is the right time to water?

Pick days with the following conditions together:

• Air temperature above 40 degrees Fahrenheit at the time you water
• Ground is not frozen at the surface, you can push a screwdriver in two inches without a fight
• No precipitation in the prior 10 to 14 days
• More dry weather forecast for the next several days

In Central Ohio, that usually means one watering session in early-to-mid January, one in early-to-mid February, and one in early March before the lawn wakes up. Some winters we get enough snow and rain that you only need to water once. Other winters, like the dry December and January we just had, you might need three or four sessions.

Which trees are most at risk?

Conifers and broadleaf evergreens are the most vulnerable because they keep transpiring all winter through their needles and leaves. A new arborvitae, white pine, or holly is going to lose moisture on every sunny windy day, and if the root ball is dry the tree cannot replace what it loses.

On a Canal Winchester install where we put in a row of six emerald green arborvitae last fall, I winter-water every two weeks during dry stretches. That row is going to look perfect in May. The same variety on a Bexley property the homeowner declined to winter-water two years ago came back in spring with three plants showing severe needle browning on the south side.

Deciduous trees like maples, oaks, and serviceberries are more forgiving because they have dropped their leaves, but their fine feeder roots still need moisture to survive freeze-thaw cycles intact.

What about mulch?

A two-to-three-inch mulch ring extending out to the drip line is one of the best things you can do for any newly planted tree, and it matters most in winter. Mulch moderates soil temperature, which keeps the freeze-thaw cycling that breaks fine roots from being as severe. It also slows moisture loss.

Do not pile mulch against the trunk. That is the volcano-mulch problem that traps moisture against bark, invites rodents, and rots the cambium. Pull mulch back two inches from the trunk so there is a clear donut around the base. I cover this and other planting mistakes in detail on our landscaping service page.

What about wrapping the trunk?

For thin-barked trees like young maples, lindens, honey locusts, and fruit trees, a light-colored tree wrap from the base up to the first major branch helps prevent southwest winter sunscald and frost cracking. Sunscald is the splitting you sometimes see on the south or southwest side of young trunks. It happens when winter sun warms the bark in the daytime, the cambium becomes active, and then a sudden temperature drop overnight kills that strip of tissue.

Wrap in November, remove in early April. Leaving the wrap on into the growing season traps moisture and invites disease. A Pickerington homeowner asked me last spring why their three-year-old crabapple had a vertical split on the southwest side of the trunk. They had never wrapped it. The split will heal slowly but the tree will be structurally weaker forever.

How do I winter-water if my spigots are shut off?

This is a Central Ohio reality. Most homeowners shut off and drain the outdoor spigots in November to prevent freeze damage. To winter-water without turning the spigot back on, you have a few options:

• Fill five-gallon buckets at a utility sink or basement laundry sink and carry them out
• Use a watering can with a long-handled trolley if mobility is an issue
• Run a short hose from a basement spigot or laundry sink temporarily on watering day

Five gallons is about 40 pounds. If you have multiple young trees, it is worth investing in a small garden cart so you can move two buckets at a time without throwing your back out.

What if the ground is frozen?

Skip that day. Watering on frozen ground means most of the water runs off into the lawn or driveway and freezes there, which is wasted water and a slip hazard. Wait for the next thaw above 40 degrees.

In a typical Central Ohio winter we get a thaw window every three to four weeks. Watch the forecast and queue up the watering chore for the warmest day in the upcoming week.

What about anti-desiccant sprays on evergreens?

I am cautiously in favor of anti-desiccant sprays like Wilt-Pruf or similar products on newly planted broadleaf evergreens, particularly hollies, boxwoods, and rhododendrons. They form a thin wax-like coating on the foliage that slows winter moisture loss. Apply in late November or early December on a dry, above-freezing day, and reapply once in mid-January if conditions stay harsh.

Do not use anti-desiccants on blue spruce or other waxy-blue conifers. The product can dissolve the natural blue waxy coating and leave the tree looking dull green for the rest of the season.

Common winter-watering mistakes I see

• Forgetting to water entirely between November and April
• Watering too fast, so the water runs off rather than soaking in
• Watering on frozen ground
• Piling mulch volcano-style against the trunk
• Skipping evergreens because they look fine in December, then losing them by April

What if I planted last fall and want a maintenance plan?

If you put in trees, shrubs, or a landscape bed in fall 2026, having someone come by every three to four weeks during winter to check moisture, refresh mulch, and water as needed is a small investment that protects the much larger planting cost. Our landscaping program includes a winter-check option on installs we did the previous season.

For full-season lawn and bed care that picks up in spring, lawn mowing bundles handle the rest of the calendar.

Want a winter walkthrough?

If you put in new plantings last year and are not sure whether they need attention right now, I can walk the property in January and tell you what to water, what to wrap, and what to leave alone.
