CARE GUIDE

How to keep Conophytum Calculus.

Light

Native to arid regions, Marble buttons grows best in full sun, its native habitat marked by intense sunlight and very little shade. It will also tolerate partial sun, giving it some flexibility in how it grows.

Water

Marble buttons, native to the arid regions of South Africa, are highly efficient at storing water and can thrive with very little moisture. These drought-tolerant plants need watering only once every three weeks and require well-draining soil. They are ideal for indoor cultivation, but it's crucial to ensure proper drainage to prevent root rot and mimic their natural dry habitat.

Temperature

Although Marble buttons has some tolerance to heat, it mainly thrives and grows in cooler seasons and goes dormant in summer. In hot summer conditions, provide shade to prevent scorching from intense sunlight. Watering should be reduced or stopped during the hottest period to avoid root rot. Marble buttons experiences vigorous growth in winter and spring. As long as temperatures don't fall too low, it will continue to grow steadily.

Fertilizer

For Marble buttons, apply light doses of fertilizer once or twice a year during the growing season. Do not fertilize in winter or summer, when the plant is dormant. Use less fertilizer for repotted plants and wait a couple of months after repotting before feeding. Fertilizing promotes healthy growth and helps induce blooms.

Pruning

Pruning is essential to maintain the shape of marble buttons, especially in the spring and autumn. It involves removing dense or redundant branches. To propagate, cut stems with 5-6 leaves, apply sulfur powder to the cut wounds, and wait for them to heal before planting. During this process, keep the soil slightly moist.

Pot & Repot

When repotting Marble buttons, choose a pot slightly larger than the current one that provides good drainage. Use a gritty, well-draining succulent or cactus mix. Gently remove the plant from its old container, brush off excess soil, and set it in at the same depth. Wait several days before watering to allow any root injury to heal. Repot in spring or fall and place it in a brightly lit location.
