Cephalocleistocactus - home care

Temperature conditions

Heat-loving cactus, the ideal temperature is in the range of 22-30 C, in winter not lower than 10 C. A fan of sudden changes in day and night temperatures.

Lighting

It is suitable for sunny window sills, but tolerates light shade in the summer. Lack of light leads to stunted growth and distortion of shape.

Care

The cactus is easy to grow, drought-resistant, very sensitive to excess watering. It likes well-ventilated places and grows slowly. In the warm season, take the cephalocleistocactus outside - this promotes flowering.

Substrate

Tolerates poor soil with a high content of coarse sand. Requires good drainage and sufficiently deep pots. Drainage should be about 30-40 percent of the total volume of the mixture.

Feeding

Feed once during the growing season with a cactus and succulent fertilizer (high potassium, low nitrogen) diluted to half the recommended strength.

Purpose

Adult specimens will require a spacious room to develop.

Flowering time

Spring.

Air humidity

Needs constant good air movement, especially when the weather is cool or humid. Thrives well in the dry atmosphere of living spaces and does not require additional humidification.

Soil moisture

Water sparingly and keep completely dry during winter.

Transfer

Repot in spring when roots become crowded, usually once a year, to provide fresh soil. After transplanting, do not water for a week or more.

Reproduction

Propagated by seeds in spring or summer. Sow seeds in well-drained sandy soil and cover with a thin layer of sand. Keep under a plastic cap for 1-2 days to maintain high humidity. Germination takes about 1 month. Stem cuttings, which are rooted in damp sand after the cut site has dried.

Pests and diseases

Excess fertilizer leads to rapid growth, but also promotes the development of fungal diseases.

Red mites, mealybugs, thrips and aphids sometimes appear.
