A note from PlantMom

Elks horns has moderate resistance to disease but is more sensitive to humidity. It becomes vulnerable to illnesses when humidity is high and is liable to develop root rot during dormancy. Regarding care needs, Elks horns tolerates drought yet requires increased watering in the growing season. Watering should be sharply reduced or stopped entirely during the dormant period. Elks horns is appropriate for people with some growing experience, though it can be challenging to care for, especially during dormancy. It is particularly suited to those who can spend time on its care over the winter months.

CARE GUIDE

How to keep Rhombophyllum Nelii.

Light

Elks horns prefers abundant sunlight, allowing it to reach its full growth potential. It benefits from generous light during all stages of development. The intense sunlight of its native habitat explains this preference. Insufficient sunlight can impede growth, while excessive exposure does not cause significant harm.

Water

Elk's horns are native to arid environments and have adapted to efficiently store water, making them highly drought-tolerant. They need to be watered only every 2-3 weeks, allowing the soil to dry out in between waterings. These plants thrive in well-draining soil and benefit from rainwater during their active growing season, which complements their minimal irrigation requirements.

Temperature

Elks horns is native to regions with moderate ambient temperatures. It does best within a temperature range of 68 to 100 °F (20 to 38 °C). Seasonal adjustments are necessary, moving toward the cooler end of that range in winter to mimic its natural habitat.

Fertilizer

Elks horns need only 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. Cut back on fertilizer for repotted plants and wait a couple of months after repotting before you start feeding again. Fertilizing helps maintain healthy growth and promotes blooming.

Pruning

To preserve the shape of elk horns, trim any redundant or dense branches in the spring and fall. When propagating, cut stems with 5-6 leaves, seal the cuts with sulfur powder, and allow them to heal before planting. Use a watering can to slightly moisten the soil for the cuttings.

Pot & Repot

When repotting Elks horns, choose a pot slightly larger than the current one that has 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 back in at the same depth. Wait a few days before watering so any root damage can heal. Repot during spring or fall and place the plant in a brightly lit location.
