To prevent winter burn an anti-desiccant should be applied to any susceptible plant material in the early winter when soil temeraptures start to drop. Anti-desiccant is a spray that creates a barrier over the pores (stomates) in the leaves. This barrier allows the plant to breath but reduces water loss through transpiration. Generally this treatment is applied to the foliage as a liquid. Anti-desiccant applications are generally made in late November- December, and again in late January. One late fall application is not enough.

Winter Burn is a common problem on Cape Cod
Very often in the early spring many evergreen plants will be spotted with brown and wilted leaves. This damage is often called winter burn. Winter burn injury is leaf damage that is caused by cold winds which dry out the leaves. Winter burn injury can take place whenever the soil freezes and wintry winds blow, drawing moisture from leaves. Plant roots can not uptake water from frozen soil to replace the losses experienced in the leaves. Winter burn can also occur when the air temperature periodically rises. The warmer temperature causes the leaves to begin the process of transpiration, the release of moisture through small pores on the surface of the leaf. The longer these conditions exist, the more moisture is lost and death of leaf tissue results. Plants that hold their leaves (evergreens) over the winter are vulnerable. Broad leaf types are more susceptible than the needle type evergreens due to the larger surface area of their leaves. This kind of damage is a common problem here on Cape Cod as our winters tend to be quite windy with unpredictable temperatures.
