Foot Rot - Mature Citrus Trees - Experts Needed
I have foot rot on my oranges. I have already lost 3 trees and 2 are I believe infected. I have seen reddish, brow sap on the trunks of both infected trees. The leaves are turning yellow and falling off. The trees are large and over 8 years old.
From all I have read this can be hard to cure and may be infectious Â is that true?
1. Proper drainage of soil
a. How do I accomplish this? Sand Mixed with current soil? I live in Whittier California.
2. Put Copper paint/solution around the trunks. Does this work?
3. Spray trunk with peroxide solutions. Does this work?
4. Cut bark of the three. Even burn away the sap. Does this work?
5. Move water source away from trunk. Water should not hit trunk. This seem reasonable Â correct?
6. Anything else?
