When Minnesota’s winter sets in, most homeowners put their garden hoses away and assume their trees can fend for themselves. After all, the ground is frozen, snow is everywhere, and watering seems unnecessary, right?
Not quite.
Even in the coldest months, trees, especially young, newly planted, and evergreen varieties, can suffer from dehydration and root damage if they don’t receive enough moisture. Understanding when and how to water your trees during winter can make the difference between a thriving landscape in spring and one struggling to recover.
At Dynasty Tree Experts, our certified arborists in Minnetonka, MN help homeowners protect their trees year-round. Here’s everything you need to know about winter watering.
Why Winter Watering Matters for Minnesota Trees
Winter might bring snow, but it doesn’t always mean water is reaching your tree’s roots. When soil freezes, water can’t penetrate deeply enough to keep roots hydrated. Meanwhile, the dry winter air pulls moisture from both the soil and the tree itself.
This is especially true in the Twin Cities area, where temperatures fluctuate and snow doesn’t consistently insulate the soil.
Here’s why watering trees in winter is crucial:
- Prevents root dehydration: Frozen ground can block moisture absorption.
- Reduces winter burn: Keeps evergreen foliage from turning brown or brittle.
- Prepares trees for spring: Well-hydrated roots promote early growth and resilience.
- Protects your investment: Healthy trees add safety, beauty, and value to your home.
When to Water Trees in Winter
Timing is everything when it comes to watering trees during winter in Minnesota. The key is to water before the ground completely freezes and during mid-winter thaws when temperatures rise above 40°F.
Here’s a simple schedule to follow:
- Late Fall (October–November): Deeply water trees before the first hard freeze.
- Mid-Winter (December–February): On warmer days above freezing, water once every 3–4 weeks.
- Early Spring (March–April): Resume regular watering once the ground begins to thaw.
How to Water Trees in Winter: Step-by-Step
Winter watering doesn’t need to be complicated. Here’s a quick guide from our team of tree care contractors in the Twin Cities, MN:
- Choose the right day: Pick a mild, sunny day above 40°F when the soil is soft enough to absorb water.
- Use the right method: A soaker hose or slow trickle works best to let water penetrate deep into the roots (8–12 inches).
- Avoid watering at night: Daytime watering prevents ice from forming around roots.
- Mulch for insulation: Apply 2–4 inches of organic mulch around the base (but not touching the trunk).
- Test soil moisture: Use a screwdriver or moisture meter to check if the soil is dry before watering again.
Proper winter watering helps trees handle Minnesota’s harsh winds and sudden freezes, reducing stress and breakage risk.
Watering Young and Newly Planted Trees
Young and newly planted trees have smaller, shallower root systems, making them more vulnerable to winter stress. Without enough moisture, their roots can dry out and die before spring.
To keep them healthy:
- Water every 2–4 weeks during winter warm-ups.
- Check moisture 6–8 inches below the surface.
- Mulch well to maintain soil temperature.
- Shield them from harsh winds with tree wraps if needed.
Healthy young trees establish faster and grow stronger when properly hydrated through their first few winters.
Common Winter Tree Care Mistakes to Avoid
Even with good intentions, homeowners sometimes make winter care mistakes that can harm their trees. Avoid these pitfalls:
- Watering when the ground is frozen: This can create ice buildup instead of hydration.
- Overwatering evergreens: Too much moisture can lead to root rot.
- Neglecting older trees: Mature trees still need moisture, especially in dry winters.
- Ignoring soil drainage: Standing water can suffocate roots when it refreezes.
- Skipping mulch: Without it, roots are exposed to extreme temperature swings.

About once every 3–4 weeks when temperatures rise above 40°F and the ground is thawed.
