We started 2018 with a polar vortex and it seems like these frigid temperatures are here to stay until spring. With so many days below freezing your plants health might be at risk.
The main cause of winter damage to trees and shrubs is their drying out. When the ground freezes plant roots are unable to take up water from the soil, so they quickly begin to use up all the water stored in their leaves and stems. Though they are built for it, the winter is still a tough time for Evergreen plants and trees. Plants such as rhododendrons and hollies have thick waxy coverings on their leaves to try to prevent water loss. During these times if plants are exposed to harsh winds or harsh sunlight the plant responds by releasing water from its leaves. This biological response, combined with the unavailability of water, results in winter burn, which can ruin your plants and shrubs.
Anti-desiccants are products that can be applied to evergreen trees and shrubs to help create a protective barrier that holds in moisture through the winter. While two applications in December and one in February is ideal, it isn’t too late to protect your plants from drying out.
Which plants benefit from anti-desiccants?
- Broadleaf evergreens such as Azalea, Boxwood, Holly, and Rhododendron.
- Conifers such as Arborvitae, Cedar, Cypress, Juniper, and Pine.
- Tender stems such as Rose Canes and Hydrangea Stems.
