Winter weather can be hard on broadleaf evergreens like holly, boxwood, azaleas, and euonymus. When the ground freezes, roots can’t absorb moisture, but leaves continue to lose water through wind and sun exposure. This imbalance often leads to winter burn, browning, and desiccation.
Applying an anti-desiccant such as Wilt-Pruf (Wilt-Stop) helps protect foliage by sealing in moisture and reducing water loss during winter conditions.
Quick Winter Protection Tips for Broadleaf Evergreens
- Apply Wilt-Pruf when temperatures are above freezing
- Spray foliage thoroughly, coating both sides of leaves
- Protect plants before prolonged cold, wind, or sun exposure
- Reapply if protection wears off during the season
Why Evergreens Need Winter Protection
During winter, frozen soil prevents plants from taking up water, while wind and sun continue to pull moisture from leaves. This can cause foliage to dry out, discolor, or drop entirely. Broadleaf evergreens are especially vulnerable because they retain their leaves year-round.
How Wilt-Pruf Helps
Wilt-Pruf is an anti-desiccant that forms a flexible, breathable coating on plant leaves. This coating slows moisture loss without harming the plant and can also provide a slight glossy appearance.
When and How to Apply
- Apply when temperatures are above freezing and dry weather is expected
- Spray foliage evenly, covering both the top and underside of leaves
- Apply in late fall or early winter before harsh conditions arrive
Plants to Avoid
Do not use Wilt-Pruf on needle evergreens such as:
- Arborvitae
- Cedars
- Junipers
- Other conifers
These plants can be damaged by anti-desiccant sprays.
