I am in Houston, Tx.
I need some advice on Plumeria Pests. This is the second year that I have grown them. The first year they were just cuttings. This year most are in the ground. The plumies in the front have orange all over the bottom of the leaves. What is this pest !!
I have tried to spray with a systemic insecticide. I hate using insecticides so I tried Neem which didn't work at all. (nothing seems to work) Is the orange an effect of spider mites. I keep spider mites off of my other plants with orange peels. Should I pull these infected leaves off of the plant.
Also, I would like to keep these in the ground even though the temps get into the mid to high 30's. My plan is the cover them with sheets. Will all the leaves fall off if I leave them in the ground. Does anyone have any suggestions other than this. They would be much appreciated. Thanks in advance. Carol
