Maihueniopsis - home care

Temperature conditions

The optimal temperature in spring and summer is 18 - 22° C. The cactus does not like extreme heat in summer. During the winter dormant period, move the cactus to a cool place, but do not allow the temperature to drop below 8° C. 

Lighting

Provide the brightest possible location. Light shading is possible only on particularly hot summer days.

Care

This cactus is unpretentious and is suitable for beginner cactus growers.

Substrate

The soil should easily pass water and air, pH not higher than 6.5. A mixture of leaf humus, turf soil with a large amount of coarse river sand or perlite to improve drainage and small pieces of charcoal is suitable. You can use a ready-made substrate for cacti and succulents. 

Feeding

During the growing season, feed monthly with a fertilizer for cacti and succulents that is high in potassium and phosphorus. In the winter months, feeding is stopped.

Flowering time

Spring Summer.

Air humidity

Does not require spraying. Prefers ventilated rooms with constant air movement, but without cold drafts.

Soil moisture

Water regularly during the warm season; allow the soil to dry to ½ depth before each subsequent watering. In winter, simply do not allow the soil to dry out completely. 

Transplant

Maihueniopsis has a taproot system, so the cactus will need a deep pot with large drainage holes. Adult plants are repotted in the spring, with the beginning of growth every 2-3 years.

Reproduction

Propagated by seeds sown in spring. By cuttings. The lateral shoots are separated with a sharp sterile instrument, the cut site is dried for several days and rooted in damp sand in spring and summer. 

Pests and diseases

Fungal diseases can occur when overwatered.

Red mites, mealybugs, thrips and aphids sometimes appear.
