Echinocactus Grusonii: How to Grow the Perfect Golden Barrel

Echinocactus grusonii, popularly known as the Golden Barrel cactus, is one of the most iconic cacti in the world. Its perfectly spherical shape and bright yellow spines make it look like a little sun in a pot. A long-lived plant, it can reach a meter in diameter in the wild but remains a compact and stylish accent in home collections.

Soil: Where Does the Cactus Feel Like It's in Mexico?

For this cactus, it is critically important that water does not linger near the roots for even a minute.

• Best Choice: Poor Sandy soils (Type 2) mixed with gravel and crushed brick.
• Soil Check: Perform the sausage test. If the soil crumbles into dust instantly (Type 2), it's the perfect drainage for your thorny friend.
