Looking for advice on why the lower leaves have been turning brown and what to do about it. The tips of the leaves are green and there are new green buds, but as you can see in the photos, the lower fronds have browned.
This is the 4th summer for the trees and the first time I’ve experienced this. Roots grew through the holes in the pot into the rocks of the evaporation tray underneath, which was often wet. I have cut them off and removed the tray. They may be root bound or the roots in the tray may have started some root rot. I think watering has been consistent with prior years, but now wondering if I’m over or under watering.
Any suggestions woul be appreciated.
