Curling Leaves on Holly Tree

Anonymous added on October 15, 2012 | Answered

I have a holly tree (JC Van Tol) with good berries, but over the last few weeks many of the leaves have started to curl from the tip ends. Some are now fully curled up. What has caused this and what do I do about it?

This is likely due to black spot fungus, which can affect many types of plants. Neem oil is an effective treatment for this fungus,as well as other types, and will help with pest too. Here is more information: https://www.gardeningknowhow.com/plant-problems/disease/black-spot-fungus.htm
