​For fall tree care, water your trees deeply to hydrate the roots, apply a layer of mulch around the base to regulate soil temperature and retain moisture, and prune dead or problematic branches to strengthen the tree for winter and encourage healthy growth in the spring. It's best to prune after the leaves have fallen to improve visibility and avoid stimulating new growth that can be harmed by cold temperatures. 
 

Water and Mulch
Deep Watering: Give your trees a long, deep watering to promote strong root development. This helps the roots absorb moisture and nutrients before the ground freezes. 
 

Focus on Roots: Water the area around the roots, particularly the critical root zone. 
Apply Mulch: Spread a 3-6 inch layer of mulch around the tree, keeping it a few inches away from the trunk. Mulch insulates the roots, keeps soil temperature stable, reduces evaporation, and adds nutrients as it breaks down. 
 

Pruning and Cleanup
 

Prune Selectively:
.
Wait until the leaves have fallen before pruning. The reduced foliage makes it easier to see the tree's structure. 
Remove Problem Branches:
.
Inspect for and remove dead, broken, or crossing branches that could cause damage or attract pests. 
Clean Fallen Leaves:
.
Rake leaves off the lawn and around the base of the tree early and often to prevent fungi and disease from taking hold in the spring. 
 

Other Considerations
 

Protect Young Trees:
Newly planted trees, and even mature ones, benefit from winter protection, as mulch helps prevent the freezing and thawing that can cause "frost heaving". 
 

Avoid Overwatering:
While deep watering is essential, avoid overwatering after the leaves drop, as this can lead to root rot, especially if the soil is already moist.
