It hasn't rained at my house for more than a month, with 90 to 100 degree heat. I am just trying to keep my tree from dying, I have given up on the garden. Nothing is growing. I am using an old trick my mother told me about. Take an empty milk carton and poke a small hole in the bottom. It lets the water out slowly right against the tree trunk. I go out a few times a day and refill the bottle.
