Deep Roots, Strong Trees, Thriving Michigan

Winter in Michigan doesn’t just bring snow and ice—it can also mean drought stress for your trees. Even when temperatures drop, trees still need moisture to stay healthy. However, when the ground freezes, roots can struggle to absorb enough water, leading to winter drought stress. Here’s how to recognize the signs and keep your trees thriving through the cold months.

Signs of Winter Drought Stress

• Browning or Yellowing Needles – Evergreens, in particular, may show discoloration as a sign of dehydration.
  

• Twig Dieback – Smaller branches may begin to wither or die back due to lack of moisture.
  

• Early Leaf Drop in Spring – Trees that suffered from winter drought stress may lose their leaves earlier than usual.

• Cracked or Dry Bark – Dehydrated trees can develop cracks in their bark, making them more susceptible to disease.

How to Prevent Winter Drought Stress

1. Water Deeply Before the Ground Freezes
   Give your trees a thorough soaking in late fall to ensure they have adequate moisture before the cold sets in. Newly planted trees and evergreens need extra attention.
   

2. Apply Mulch for Moisture Retention
   A 2–4 inch layer of mulch around the base of your trees helps insulate the soil and retain moisture. Just be sure to keep mulch a few inches away from the trunk.
   

3. Avoid Salt Exposure
   De-icing salt can contribute to dehydration. Try using sand or an environmentally friendly ice melt near your trees to prevent salt damage.
   

4. Use Anti-Desiccant Sprays for Evergreens
   Anti-desiccant sprays help evergreens retain moisture by creating a protective barrier on their needles. Apply these sprays in late fall before freezing temperatures arrive.
   

5. Monitor Weather Conditions
   If winter temperatures fluctuate and you experience a mid-season thaw, take advantage of it by giving your trees a slow, deep watering to replenish moisture levels.
