Dear Mr Bob,
My woodtrees are 12 feet high and about 7 inches in diameters at the trunk. They do not look as healthy as they should. The branches are sticking down instead of up, some of the leaves are getting brown from the center. Can I use the root feeder to feterlizer them? What kind of should I use?
How many times should I water them a week and how long each time?
Thank you very much
