Cactus
General
WATER - Spring/Summer: Water once every two weeks or once a week if placed in a very hot window. Make sure to fully drench the soil until water comes out the bottom. Fall/Winter: During the cold, dormant months reduce watering to once a month and only when the soil is completely dry.
LIGHT - Outdoors or a bright window is best. They are desert plants after all.
SOIL - Well draining potting soil.
CARE - Fertilize once a month in growing season - Spring and Summer.
