Gary, I'm just starting out in Maryland (see attach photo). Because of the harsh winters here, sometimes near zero degrees, I'm going with potted cacti that can be brought indoors during the coldest months. Anyway, with what I've read from you about your success in Tennessee, you're an inspiration to me. In another thread, you mention watering your Giant Saguaro a little very day, and giving it a teaspoon of 20-10-10 each week. Looking at my photo, how much water do you figure is enough, on days when it doesn't rain?
