Q.Camellia Tree – Yellow Leaves With Red Spots
We have 2 well established Camellia Sasanqua White trees. Over the past few weeks the leaves have been turning yellow, and now we see they also have red spots. Do you know what caused this and recommend the best course of action? Many thanks, Sophie

This is what is known as shothole fungus! This article will help you with treatment:

Thank you for your reply BushDoctor - it's good to know what the problem is. Looks like our long wet winter is what caused this shothole fungus...
The treatment is to remove all affected leaves and destroy them. I worry that these evergreen trees may never recover again since one is 90% affected the other about 60%. Can the trees survive with only a few leaves on??
Also the 2 trees are planted right next to a large and very beautiful climbing hydrangea... can the disease jump across? (Please no!)
Many thanks, Sophie
