Ferocactus macrodiscusis a medium sized barrel cactus up to 11.8 inches (30 cm) in diameter, with a blue-green epidermis and 16 to 21 ribs. The spines are yellow or red and curved, up to 1.4 inches (3.5 cm) long. Flowers are bright purple or pink and white striped, up to 4 cm in diameter.

How to Grow and Care

Choose a planting location that receives direct sun during all or most of the day. Water the cactus at the time of planting to anchor it into the soil. Plant your Barrel 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.
