How to Treat Curly Leaves on a Plum Tree
Curly leaves on plum trees are often caused by leaf curl aphids (Eriosoma lanigerum). These aphids secrete a substance that causes the leaves to curl inward. The aphids can be found on the undersides of the leaves.
To treat curly leaves on a plum tree, you can use insecticidal soap or neem oil. Insecticidal soap is a natural insecticide that kills insects by breaking down their outer coating. Neem oil is also a natural insecticide that has antifungal and antiviral properties.
To use insecticidal soap, mix 1 tablespoon of soap per gallon of water. Spray the soap solution on the undersides of the leaves, making sure to cover all of the aphids. Neem oil is used in the same way as insecticidal soap.
Once you have treated the aphids, you can prune off the infected leaves. This will help to improve the tree's appearance and prevent the aphids from spreading.
