Dormant Oil and Lime Sulphur Treatment

Dormant oil and lime sulphur treatments have been used for many years to clean deciduous trees of moss and algae, as well as many overwintering insects and diseases such as aphids, mites, webworms, scale insects and black spot fungus. Preventing an accumulation of moss and algae can aid in maintaining the structural integrity of the tree and diminishing the overwintering insect population can prevent or reduce the need for further pesticide applications during the growing season.

In fact, because of its safety and relative low toxicity, it is the preferred treatment by those of us concerned about our environment. To assist in maintaining optimal health for deciduous trees, we recommend this treatment of mineral oil and lime sulphur during the winter months.
