Description

Ferocactus wislizeni is a barrel shaped or columnar cactus with cylindrical stem, up to 30 inches (80 cm) in diameter and up to 6.5 feet (2 m) tall. The spines are thick and hooked. It has a leathery asparagus green skin with approximately 15-28 ribs per cactus. Its flowers are yellow to red-orange with reddish midribs and brown tips, up to 3 inches (7.5 cm) long and appear atop the cactus fruit during the summer months. The fruits are green when unripe, yellow after the flower dries up, and persist atop the cactus long after the flower is gone, sometimes for more than a year.

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.
