Protecting Broadleaf Evergreens

As winter draws near in Port Huron, Michigan, homeowners and arborists must prepare broadleaf evergreens to face the harsh cold. One effective method for protecting these plants is using anti-transpirant sprays, which provide a protective barrier against winter's drying effects.

What Are Anti-Transpirant Sprays?

Anti-transpirant sprays, also called anti-desiccants, are protective solutions applied to the foliage of plants. These sprays form a thin, waxy film over the leaves, reducing moisture loss during winter. By limiting water evaporation, they help prevent the drying effects of winter, ensuring the plants stay hydrated even when the ground is frozen and they cannot absorb water.

Why Broadleaf Evergreens Benefit

Broadleaf evergreens, such as holly, rhododendron, and boxwood, are especially prone to winter desiccation. During the colder months, these plants lose moisture from their leaves but often can't replenish it due to frozen soil. Anti-transpirant sprays can:

•    Reduce moisture loss from evergreen plants
•    Protect leaves from winter burn and scorching
•    Keep your landscape looking healthy and vibrant throughout the season

How to Apply Anti-Transpirant Sprays

To achieve the best results in Port Huron’s climate, follow these key application tips:
1.    Apply the spray in late fall, before temperatures drop to freezing.
2.    Choose a day when the temperature is between 40-50°F. This range allows the spray to effectively cover the leaves.
3.    Make sure to coat both the top and bottom of the leaves thoroughly for full protection.

Important Considerations

While anti-transpirant sprays can help, they are only one part of a successful winter care plan. Plant selection, regular watering before the freeze, and proper mulching are just as important in ensuring your plants’ survival. Additionally, in some cases, using physical barriers like burlap screens may be necessary to protect plants from extreme wind or sun exposure.

By incorporating anti-transpirant sprays into your winter care strategy, you can enhance your broadleaf evergreens' ability to withstand cold months in Port Huron and thrive when spring arrives.
