bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well); an east- or north-facing window is ideal during the blooming season. During the 6-8 week bud induction period in early fall, the plant needs 12-14 hours of uninterrupted darkness per night - even brief light exposure at night can prevent bud formationLight

keep evenly moist (water when the top inch of soil starts to dry. The goal is damp, not soggy -- think wrung-out sponge) during the spring through late summer growing season; water lightly in fall once buds begin to form. The plant prefers moist, well-draining conditions rather than the dry-between-waterings approach typical of desert cactiWater

Prefers moderate to high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby); bathrooms with bright indirect light are genuinely well-suited to this plant. Use a pebble tray or humidifier in dry homesHumidity

70-80F (21-27C) during active growth; cooler temperatures of 50-55F (10-13C) at night for 6-8 weeks in early fall trigger bud formation. Once buds appear, keep conditions stable - temperature fluctuations cause bud dropTemperature

Christmas Cactus

Schlumbergera truncata

Easy

Thanksgiving Cactus looks a lot like Christmas Cactus until you check the edges: this one has distinctly pointed, claw-like projections on its flat stem segments, which is where the 'crab cactus' nickname comes from. It blooms 3–6 weeks ahead of its cousin, typically in late October through November, with tubular flowers in red, pink, purple, orange, or white that stand more upright than the drooping blooms of the Christmas type. Hummingbirds are its natural pollinators.
