My silver dollar eucalyptus tree, 4' tall, has brown spots on the leaves and they are falling off. Is it fungus? What to do? I'm in the north Phoenix, AZ area, very dry humidity this spring.
Tomato plants' leaves are turning brown, drying out, curling up. I spray water over the plant every other day, water every other day. It is potted, gets morning sun, about 4-6 hrs daily. I sprayed with Palmolive liquid/water.
