Care and maintenance of Echinocactus – Spiny ball cactus or Mother-in-law's cushion

The Echinocactus , better known as the spiny ball cactus or “mother-in-law’s seat cushion,” is a standout in the world of succulents. This cactus gets its nickname from its unique spherical shape and thick spines, which are both aesthetically pleasing and protective in their natural environment. This plant is an ideal choice for those looking for a low-maintenance and decorative houseplant or garden plant.

Caring for an Echinocactus is relatively easy. Place the plant in a sunny spot, preferably in a south- or west-facing window, where it will receive at least six hours of direct sunlight per day. A lack of light can lead to elongated growth instead of the characteristic spherical shape. In winter, make sure it is kept in a cool room with sufficient light, as a rest period is essential for its health.

Watering an Echinocactus is easy, as long as you are careful not to overwater. Allow the soil to dry out completely before watering again, especially during the winter months when the cactus is dormant. In the summer, it will need more frequent watering, but always in moderation. Overwatering can lead to root rot, which can be fatal for this desert dweller.

The Echinocactus does best in a well-draining substrate, such as cactus soil mixed with sand or perlite. This mimics its natural habitat, where excess water drains quickly. Make sure the pot has drainage holes so that excess water can drain away.

Feed the cactus during the growing season (spring and summer) with a special cactus fertilizer that contains little nitrogen. This promotes healthy growth and can even contribute to the formation of flowers, although it can take years for an Echinocactus to flower. Avoid fertilizing during the dormant period in winter.

The Echinocactus grows slowly, but it can eventually grow to an impressive size and live for decades. Its slow growth also makes it suitable for small spaces, as long as it gets enough light.
