I have three exceptionally tall crape myrtle trees in my backyard. For the last few weeks, considerable amounts of yellow leaves have been falling from those trees. The trees are situated in a garden which primarily has Knock Out rose bushes that have been recently pruned and fertilized with Osmocote (17-3-6).
Can you advise the cause of the falling leaves and the suggested solution?
Thank you,John H.
With all the rain this spring, we are currently seeing an outbreak of Cercospora leaf spot on crape myrtles here in southeast Louisiana. Click here for information on this disease – let me know if you have any questions.
