How to Care for Christmas Cactus
A Christmas cactus (Schlumbergera bridgesii) is one of the most beloved houseplants during the holiday season.
Known for its vibrant flowers that bloom in winter, this tropical cactus is quite different from desert species.
With the right care, it can live for decades, becoming a family treasure passed down through generations.

If you want to keep your Christmas cactus thriving and blooming year after year, here’s everything you need to know.
Identifying Your Holiday Cactus
Many people confuse the Christmas cactus, the Thanksgiving cactus, and the Easter cactus.
While they belong to the same family, they bloom at different times and have slightly different leaf shapes.
Christmas cactus usually blooms in late December, with rounded stem segments and arching flowers.
Knowing which plant you own helps you understand its natural cycle and when to expect flowers.
Choosing the Right Pot and Soil
A Christmas cactus doesn’t like sitting in soggy soil. Always choose a pot with drainage holes to prevent root rot.
A lightweight container made of ceramic or plastic works best.
For soil, use a well-draining mix—a combination of cactus soil, peat moss, and perlite creates the right balance of moisture and aeration.
These plants prefer to be slightly root-bound, so don’t rush to repot too often.
Light Needs
Place your plant in a bright spot with indirect sunlight. A north or east-facing window is ideal, where the plant gets plenty of light without the harsh midday sun.
Direct sunlight can scorch the leaves, while too little light reduces blooming.
In summer, you can move the plant outdoors to a shaded patio, but bring it back inside before temperatures drop.
Watering and Humidity
Unlike desert cacti, the Christmas cactus comes from tropical forests where humidity is high.
Water thoroughly whenever the top inch of soil feels dry, then let excess water drain completely.
Never let the plant sit in water.
To increase humidity indoors, place the pot on a tray with pebbles and water or mist the leaves occasionally.
A humidifier also helps during dry winter months when heaters are running.
Temperature and Blooming
This plant thrives in temperatures between 60–70°F (15–21°C) during the day and slightly cooler nights.
To encourage blooms, provide about 14 hours of darkness and cooler temperatures (around 55–60°F / 12–15°C) for six weeks in autumn.
This mimics natural conditions and triggers the plant to set buds. Once buds appear, return the cactus to normal light and warmth.
Feeding Your Plant
During the growing season (spring through early fall), feed your Christmas cactus every 4–6 weeks with a balanced, water-soluble fertilizer diluted to half strength.
Stop fertilizing once buds begin to form, as too much feeding during this time can cause bud drop.
Pruning and Propagation
After the blooming season, you can prune the plant to maintain shape and encourage branching.
Simply twist or cut off a few stem segments. These cuttings can be used for propagation—let them callus for a day, then plant them in a small pot with moist soil.
Within weeks, new roots will develop, giving you more plants to enjoy or share.
Repotting Tips
Repotting is only necessary every 2–3 years or when the plant becomes pot-bound.
Do this in late spring after blooming has finished. Choose a pot only one size larger than the current one and refresh the soil mix.
Avoid repotting when buds are forming, as it can stress the plant and cause flowers to drop.
Common Problems and Solutions
Even with good care, Christmas cacti sometimes face challenges. Here are some issues and how to fix them:
Bud Drop – Usually caused by sudden changes in light, temperature, or watering. Keep conditions stable once buds form.
Yellowing Leaves – Can indicate overwatering or poor drainage. Check the soil and roots for rot.
No Blooms – The plant may not have received enough darkness and cool nights in fall. Try the six-week bloom-inducing method.
Pests – Watch for mealybugs or scale. Treat with insecticidal soap or by wiping leaves with a cotton ball dipped in rubbing alcohol.
Seasonal Care Tips
Spring – Resume watering regularly, begin fertilizing, and allow new growth.
Summer – Place outdoors in shade, water more frequently, and protect from direct sun.
Fall – Start the bloom cycle with cooler nights and long dark periods. Reduce watering slightly.
Winter – Enjoy the blooms, maintain stable conditions, and avoid moving the plant too much.
Keeping Your Christmas Cactus Thriving
With the right combination of light, water, temperature, and seasonal adjustments, your Christmas cactus will reward you with stunning blooms year after year.
These resilient plants can live for decades and even become family heirlooms when properly cared for.
By following these tips and paying attention to your plant’s needs, you’ll enjoy a cheerful burst of color every holiday season.
