Damage caused by long dry periods of cold and thaw can seriously impact broadleaf evergreens, conifers and tender stem plants.
The cold winter temperatures can cause serious damage to many of our plants. An early winter anti desiccant spray can help. This waxy coating serves as a layer of protection to the leaves of broadleaf evergreens, conifers and tender stems helping to insulate and slow down the process of transpiration.
Susceptible Plants Include:
- Broadleaf evergreens: Including azaleas, boxwoods, hollies and rhododendrons
- Conifers: Including arborvitae, cedar, cypress, juniper and pine
- Tender stems: Including rose canes and hydrangea stems
If you are concerned about winter injury, consider using an anti desiccant spray.
Some tips to remember:
- Always follow the directions on the product carefully
- Pick the best time to spray: Anti desiccants should be applied when temperatures are approximately between 40-50 degrees and with no rainfall in the forecast. It is best for the foliage to be dry when sprayed and the coating needs time to dry.
- Don’t spray early
- Spray thoroughly: Spray the entire plant
- Be aware: Check to be sure the plants you are spraying need to be sprayed. For example, blue conifers do not need to be sprayed because they have a natural coating of their own.
