Winter Watering: When, How, & How Much Do Trees Need?

Key Takeaways:
- Winter watering is essential in Colorado’s dry climate, even when trees are dormant and temperatures are cold.
- Watering trees in winter during dry periods helps prevent dehydration, root damage, and delayed spring growth.
- The frequency of watering in winter depends on tree age, soil conditions, and weather patterns rather than a fixed schedule.
Do Trees Need Water in the Winter?
In most cases, yes. It’s a common misconception that trees don’t need water once winter arrives. In Colorado’s dry climate, winter watering is one of the most important and overlooked steps in protecting tree health through the cold months. Even while dormant, trees continue to lose moisture, especially during warm, windy, or snow-free periods.
Why Winter Watering Matters in Colorado
Colorado winters often bring long stretches without snow cover, low humidity, and frequent chinook winds. These conditions dry out soil and roots, leading to winter dehydration, root damage, and increased stress come spring. Properly watering trees in winter helps prevent dieback, cracked bark, and delayed leaf-out.
If you’re wondering, “Should I water trees in winter?” the answer depends on weather and soil conditions, but skipping it entirely can do more harm than good.
When and How Often to Water Trees in Winter
The cadence of watering trees in the winter depends on tree age and conditions. Established trees may only need watering once every 3–4 weeks during dry periods, while younger or newly planted trees often need more frequent attention.
For effective winter watering:
- Water on warmer days when soil can absorb moisture
- Focus on the root zone, not the trunk
- Apply water slowly so it soaks deeply
When to Stop Watering Trees for Winter
There isn’t a set calendar stop date for watering trees in winter. You should continue to water them until the ground freezes, and even afterward during extended dry spells when temperatures rise above 40°F.
Proper care and winter weather preparedness helps trees conserve energy during dormancy and reduces stress heading into spring.
