Stick your finger down to almost the second nuckle and if the aloe is dry all the way down then give it a good dollup of water. Otherwise not. They are a sucellent(sp) and hold water. So you want to dry them out between waterings. Also they go dormant from time to time and need almost no water. If you can't post pictures here tell us what the other plants
look like. With standard house plants
it's suprising how fast the experts can identify a plant
I was discussing a bush that is down in one of the containers and in the snap of your fingers two people came up the plants
name (it was barberry).
