A note from PlantMom

Stomatium alboroseum has moderate disease resistance and is more sensitive to humidity. It becomes vulnerable to disease when humidity is high and is prone to root rot during dormancy. In terms of care, Stomatium alboroseum tolerates drought but requires increased watering in the growing season. Watering should be greatly reduced or stopped entirely during the dormant period. Stomatium alboroseum is best suited to growers with some experience, as it can be challenging to care for, especially during dormancy. It is particularly appropriate for those who can dedicate time to its winter care.

CARE GUIDE

How to keep Stomatium Alboroseum.

Light

Stomatium alboroseum, indigenous to dry areas, flourishes under direct sunlight, mirroring its original habitat defined by intense sun exposure and scarce shade. It also tolerates partial sunlight, demonstrating some flexibility in its development.

Temperature

Stomatium alboroseum can withstand some levels of heat, yet it grows best during the colder seasons, becoming inactive in the summer. It's crucial to offer shade during the hot summer months to avoid damage from harsh sun rays. Also, watering should be limited or even stopped during the warmest season to prevent the roots from rotting. The growth of Stomatium alboroseum is usually vigorous during the winter and spring seasons. Provided the temperature doesn't fall extremely low, its growth will persist steadily.

Fertilizer

For Stomatium alboroseum, administering small amounts of fertilizer 1-2 times annually during the growth period is adequate. Refrain from fertilizing in the winter and summer periods when the plant is in hibernation. Decrease the fertilizer amount for replanted plants and hold off for a few months after replanting before you start fertilizing. This process aids in robust growth and the generation of blooms.

Pot & Repot

During the repotting of Stomatium alboroseum, it's advisable to opt for a pot that's a tad larger than the current one and is equipped with efficient drainage. Utilize a gritty succulent or cactus mix that drains well. Proceed to gingerly extract the plant from its previous pot, brush away surplus soil, and then place it back at an identical depth. Hold off on watering for several days as this lets any injury to the roots recover. Carry out the repotting in either spring or fall, ensuring to situate the pot in a zone with adequate light.
