info
Most cactus are from the deserts of the world and as such like to go totally bone dry between waterings, making them very low-maintenance. If you see your cactus begin to shrivel or lose firmness, your cactus is likely totally dry and should be watered. To get good healthy growth your plant doesn’t want to sit around totally dried out during it’s growing season. Once it is dry, water it.

This cactus comes from an area with summer rainfall and is actively growing during that time, when it is forgiving of overwatering errors. During winter dormancy it should be kept extra dry and won’t tolerate overwatering.

Remember that if kept in a small pot your plant will want more frequent watering.

This cactus is considered easy to grow. If you are near the coast this plant will tolerate full sun, but will burn inland in areas with hot summers.
