It thrives best in bright filtered light or partial shade. They do not like the direct full sun, but morning and late afternoon sun are okay.

It will grow in soil with a pH of 5.0 to 9, however, they prefer soils with a higher-alkaline pH of 6.2 to 7.0. Adding organic fertilizer can add nutrients to the soil, and can likewise help balance pH levels, as most organic fertilizers have a pH of around 7.0.

Normal room temperatures 60-75°F/16-24°C. To set blossom buds, the plant needs 8-10 weeks of cool 60-65°F/16-18°C days and 45-55°F/7-13°C evenings in winter.

Keep the soil wet spring through fall, while the plant is growing. In winter, water sparingly until the point that new growth starts in spring. Never enable it to dry out. Shriveled, limp stems are a sign the soil is too dry. After blossoming, rest one month before fertilizing. Don’t over-fertilize.

Apply a diluted NPK 10-10-10 fertilizer once a month during the growth period and cactus fertilizer (NPK 0-10-10) to promote flowering.

Propagate from the seed in spring or late-spring. Remember that Disocactus does not always come true from seed.  Also, propagate from stem cuttings in early summer.
