Winter Watering: Protecting Trees and Shrubs in Dry, Cold Months

Winter may bring snow and ice, but many regions across the country still experience long stretches of dry weather that can stress trees and shrubs. While plants may be dormant, they still require moisture to survive. Without proper winter watering, trees and shrubs—especially young or newly planted ones—can suffer dehydration, leading to weakened growth in spring or even plant loss.

Why Winter Watering Is Important

Even when plants aren’t actively growing, they continue to lose moisture through their roots and foliage. Dry, frozen soil can prevent water uptake, leading to drought stress. Evergreens, in particular, are vulnerable as they lose moisture through their needles all winter long. Without supplemental watering, trees and shrubs may struggle to recover when the growing season returns.

How Often Should You Water?

The need for winter watering varies depending on climate and soil conditions, but general guidelines include:

  • Water when temperatures are above 40°F with no snow cover and when the soil is not frozen.
  • Water once or twice per month from late fall through early spring, depending on precipitation levels.
  • Water during midday so the moisture has time to soak in before nighttime temperatures drop.

Best Practices for Winter Watering

  • Deep water the root zone using a slow, steady application method like a soaker hose or deep-root watering tool. This helps the water penetrate deeply and reach the roots.
  • Prioritize newly planted trees and shrubs since their root systems are still developing and need extra care.
  • Avoid overwatering—too much moisture can lead to root rot if the soil remains overly saturated.
  • Focus on evergreens because they continue to transpire (lose water) throughout winter.

Additional Tips for Protecting Plants in Winter

  • Apply mulch around the base of trees and shrubs to help retain soil moisture and regulate temperature.
  • Check soil moisture regularly by inserting a screwdriver or soil probe—if the soil is dry a few inches down, it’s time to water.
  • Use windbreaks in areas with harsh winter winds to help reduce moisture loss from evergreens.

Final Thoughts

Winter watering is a simple yet essential practice to keep trees and shrubs healthy through the colder months. By providing occasional deep watering in dry periods, you can prevent dehydration and help your landscape thrive when spring arrives.
