There are several things you can do to care for your trees during the winter months:

1. Water your trees during dry spells: Even though it's cold and there may be snow on the ground, trees still need water. If there's a dry spell during the winter, be sure to water your trees to prevent them from drying out.

2. Protect your trees from damage: If you live in an area with harsh winters, you may want to wrap your trees in burlap or use tree wrap to protect them from cold winds and ice.

3. Prune dead or damaged branches: Pruning away dead or damaged branches can help promote healthy growth in the spring. Be sure to do this before the winter to prevent the weight of snow and ice from causing further damage.

4. Mulch around the base of your trees: Mulching helps to insulate the roots of your trees and can protect them from extreme temperature changes.

5. Keep an eye on your trees: Regularly check your trees for any signs of damage or distress. If you notice any problems, you may need to take action to protect your trees from further damage.
