Using Neem Oil on Freshly Planted Trees

dkamarinos added on December 21, 2016 | Answered

I recently just planted last Thursday two bare root trees, both a crabapple and a kwanzan cherry tree. I live in Zone 9, east coast of Florida, and the weather hasn't really dipped down lower than upper 50s for a low yet, and on some days are getting into mid 80s for a high. I am concerned that these trees, since they are young and freshly transplanted, may be especially vulnerable to fungus and other threats before they have a chance to acclimate. Would it be safe to mildly spray the trunks with neem oil? I have had great success treating my rose fungus issues with neem oil. It has made a significant impact on reducing the amount of black spot, among other types of fungus. The roses are now healthier than ever, appearing more green with consistent full foliage.

I would avoid using anything on the newly planted trees unless you they are displaying sign of disease or pests.
If your tree needs treatment, we agree that Neem Oil is a great organic method to use.
