My 7' Paulownia tree, planted a year ago, has large leaves with holes and brown edges, and most have fallen off. After spraying with Specticide Immunox, I’m unsure if it helped. What could be the cause, and what can I do to fix it?
The leaves are falling due to drought and early fall color. I would not worry about condition of leaves or insects at this time. I would ensure that watering is adequate.
