How to Grow and Care
Choose a planting location that receives direct sun during all or most of the day. Because Ferocactus eventually leans into the sun instead of growing precisely upright and because it has extremely sharp thorns, place it where people will not brush into it accidentally.
Plant your cactus in early spring before new roots begin to form in late June and early July. 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. Ferocactus thrives in poor and arid soil.
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… – See more at: How to Grow and Care for Ferocactus
