Water Christmas Cactus every 10 days as a baseline. Treat that as a reminder to check rather than a rule to follow blindly — push a finger an inch or two into the soil and water only if it feels dry at that depth.
Expect to water more often in warm, bright, or dry conditions, and noticeably less in winter when growth slows. A pot with drainage holes matters more than the exact interval: standing water is the most common way houseplants are lost.
Christmas Cactus prefers bright, indirect light. It wants plenty of light without direct sun falling on the leaves — a spot near an east-facing window, or a few feet back from a bright south-facing one, works well.
If growth becomes stretched and leggy with long gaps between leaves, it is reaching for more light. Pale or bleached patches usually mean the opposite — too much direct sun.
Feed Christmas Cactus about once a month through the growing season using a balanced liquid fertilizer at half the strength on the label. Pause over winter — an unfed plant recovers far more easily than one with fertilizer burn.
Flowers when days get shorter. Water more freely when in bloom; let it dry between waterings the rest of the year.
As a starting point, water Christmas Cactus every 10 days, then adjust to your own conditions. Check the soil first: push a finger an inch or two down and only water if it feels dry at that depth. Most Christmas Cactus problems come from watering on a fixed schedule rather than watering when the plant actually needs it.

Feed Christmas Cactus about once a month during the active growing season (roughly spring through early autumn) with a balanced liquid fertilizer at half strength. Stop feeding in winter, when growth slows and unused nutrients build up in the soil.
Christmas Cactus is grown as an indoor plant. It does best in stable room temperatures, away from cold draughts and radiators.
