Please Help.
I have several citrus trees that are struggling and I think it is because of Cicada Nymph in the potted plant dirt. I suspect this because the trees (mainly one) has been yellowing with deformed shriveling leaves since last year. I noticed exit wounds on the tree branches this summer and I believe that Cicada Nymphs have infested my pots and are eating at the root systems.
I need to know if there are any ways to drive these suckers out of my potted plants. The only other option I can think of is to re-pot them all, which I will do if necessary but I am not sure if I will be successful at removing them all from the dirt by hand.
