I have three plants that I water weekly. We will be gone two and a half weeks. I don't wan to trouble anyone with having to come in and water then and they are really to large to move easily. In the past, I have gotton them good and moist prior to leaving. Then I take a 2 liter coke bottle, fill it with water and turn it upside down, putting the bottle opening into the plant pot soil. As the plant dries out, the water seeps into the plant. When I come home, the plant is still alive and the bottle is empty. Does anyone have a better method? Thanks,
