In Dryden, Michigan, as winter approaches arborists and homeowners face the challenge of protecting broadleaf evergreens from the harsh winter elements. One effective solution gaining popularity is the use of anti-transpirant sprays.

What Are Anti-Transpirant Sprays?

Anti-transpirant sprays, also known as anti-desiccants, are protective coatings applied to plant foliage. The product we use forms a thin, polymer-based film that helps reduce moisture loss from leaves during the winter months.

Benefits for Broadleaf Evergreens

Broadleaf evergreens like hollies, rhododendrons, and boxwoods are particularly susceptible to winter desiccation. By applying anti-transpirant sprays, you can:

• Reduce water loss by as much as 50%
• Protect against winter burn and leaf scorch
• Maintain the aesthetic appeal of your landscape

Application Tips for Winter Anti-Transpirant Sprays

For best results in Dryden's climate:

1. Apply in late fall, before freezing temperatures set in
2. Choose a day with temperatures of at least 40°F
3. Ensure thorough coverage of both upper and lower leaf surfaces

Considerations Before Applying a Winter Anti-Transpirant Spray

While anti-transpirant sprays can be beneficial, they're not a cure-all. Proper plant selection, adequate watering – especially in the fall, and mulching are equally important for winter protection. Additionally, sometimes a physical barrier, such as burlap, is required to shield evergreen plants from the winds as well as the anti-transpirant spray.

By incorporating anti-transpirant sprays into your Plant Health Care plan, you can help your broadleaf evergreens in Dryden, Michigan survive the cold months and emerge vibrant and healthy in the spring. Call Owen Tree & Lawn Care today to find out which evergreen plants in your landscape would benefit from a winter anti-transpirant application.
