Broadleaf plants such as Rhododendron, Holly and Azaleas (among others) can give away moisture during the Winter. However, if the soil is frozen, the plant can not resupply itself. This is bad and can lead to Winter burn. Antidessicant is an organic spray that can coat the leaves with a wax to prevent moisture loss. Thus reducing the potential for burn and hopefully protecting those all important flower buds.
