Start the season right
Plant christmas cactus in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Christmas Cactus prefers pH 5.5 to 6.5 (Growable Ground Plant Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Keep it in good form
Prune christmas cactus to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
