small black insects on the leaves of my wisteria. some of the leaves are turning yellow. Please advise me what to do. Thanks, Diana Middletown Va firstname.lastname@example.org
The most common insect pests of wisteria are aphids and scale. Aphids can cause leaf yellowing and leaf curl. Scale insects usually cause a general decline of the plant. From your brief description, I can't be certain what insect is affecting your wisteria. You could take a sample to your local cooperative extension office or a knowledgeable garden center for identification. It would be good to identify the insect before prescribing a control.
