Mammillaria elongata 'Copper King'

Care at a glance

Water

Water deeply only when the soil is completely dry, typically every 2-4 weeks during the growing season. Reduce watering significantly in winter to monthly or less.

Light

Provide at least 6 hours of direct sunlight daily; a south-facing window is ideal. It can tolerate some afternoon shade in very hot climates.

Humidity

This cactus prefers low humidity, typical of arid environments.

Temperature

Maintain temperatures between 60-75°F (15-24°C) during the growing season, and no lower than 40°F (4°C) in winter.

Soil

Use a well-draining cactus or succulent potting mix, optionally amended with extra perlite or pumice.

Fertilizer

Feed with a diluted low-nitrogen cactus fertilizer once a month during spring and summer.

Toxicity

Mammillaria elongata is generally considered non-toxic to pets and humans.

Propagation

Propagate easily from offsets (pups) that grow around the base of the plant. Allow cuttings to callus for a few days before planting in dry, well-draining soil.
