Fruitless Mulberry tree. Had a problem with webb worms, now gone due to spraying. Leaves are turing yellow and dropping to lawn. Mostly young grow affected. What to do?

Summer where your at? Hot?
Water twice a week if your allowed.

This will keep the water where you want it:
Take a plastic gallon jug and cut out one side, place the cut-out side on the ground. Stick the hose through the top where the lid screws on. (if you have one of the old time brass screw nozzels) Crack it open a bit and let it run for 10-15" minutes, that's approximitaly 5gals.

Keep an eye out for the worms for next year, try and spray in the Spring when it is cooler, even fall for next year
