Tree and Shrub Health: How to Prepare Your Trees and Shrubs During Michigan Winters

While fertilization and disease control are essential for maintaining tree and shrub health, preparing for Michigan's harsh winter conditions is equally important. The combination of snow, ice, and fluctuating temperatures can stress plants, leading to potential damage that impacts their vitality.

Here are a few tips for protecting trees and shrubs during the winter months:

1. Insulate With Mulch

Applying a three inch layer of mulch around the base of your trees and shrubs helps regulate soil temperature, reduces water loss, and keeps roots insulated from freezing. Be careful not to pile mulch directly against the trunk to avoid rot.

2. Water During Dry Periods

Even in winter, trees and shrubs require water, especially during extended dry spells. Make sure to water the root zone thoroughly before the ground freezes or during any mid-winter thaws.

3. Protect Against Winter Burn

Evergreen shrubs are particularly susceptible to winter burn, caused by dry winds and frozen soil. You can protect them by using burlap wraps or creating windbreaks that help retain moisture and prevent desiccation.

4. Prevent Snow and Ice Damage

Heavy snow or ice accumulation can weigh down branches, leading to breakage. Instead of shaking branches, gently remove snow with a broom by sweeping upward to avoid causing further damage.

5. Prune Carefully

It’s wise to prune any damaged or weak branches before winter to help prevent them from breaking under stress. However, refrain from heavy pruning in winter, as this can encourage unwanted growth come spring.

By taking these simple measures, you ensure your trees and shrubs withstand winter stress and emerge healthy in spring. Healthy plants are not only more resilient to diseases but also reduce future maintenance costs and efforts.
