How to Grow and Care
Choose a location that receives direct sun during all or most of the day. Plant your Barrel Cactus in early spring before new roots begin to form. The roots may appear dry, but that is typical before new growth begins. Dig a hole deep enough for the plant's roots and amend it as needed to provide fast-draining soil. A good soil mixture includes 10 percent native soil, 45 percent washed sand or pumice, and 45 percent compost.
Water the cactus at the time of planting to anchor it into the soil. Water again only if the weather in your area is unseasonably dry and if normal spring or winter rainfall doesn't occur. Ferocactus needs a dormant period with dry soil during the winter.
