In the period from March to October water regularly, trying to always keep the soil slightly damp, but not soaked with water, as the Columnea crassifolia does not like the water stagnation that can cause dangerous root rot. In winter supply water very rarely, every 15-20 days, to prevent the plant from drying out. In the vegetative period, provide fertilizer for flowering plants every 15-20 days, mixed with the water used for watering.

Columnea crassifolia fears the attack of aphids, cochineal and whitefly. There are special insecticide products on the market that can be used successfully to solve the problem; if the attack of the cochineal is contained, it is also possible to intervene manually to eliminate the parasites by means of a cotton pad with alcohol.
