Christmas Cactus – How to ID & Care for Everyone’s Favorite Holiday Plant

I understand you’re likely here because someone has informed you that your plant isn’t a Christmas cactus, or perhaps you’ve had one for a while but are struggling to make it bloom. Whether you’re dealing with confusion about the plant’s identity or wondering if it’s time to repot, this comprehensive post is designed to address all your Christmas cactus care inquiries.

Take a moment, grab a warm beverage, and get comfortable. By the time you finish reading, you might discover something new about this beloved holiday plant – unless, of course, it happens to be your favorite festive plant.

Commonly Misunderstood

Christmas cacti often find themselves at the center of misunderstanding. These plants tend to have a reputation for either not blooming at all or blooming at unexpected times. Many people have inherited these plants through family cuttings, leading to a peculiar phenomenon where only certain individuals seem capable of coaxing blooms from them.

Compounding the confusion is the broad use of the term “Christmas cactus.” Many enthusiasts are discovering that the plant they’ve been caring for may not be a true Christmas cactus. The prevalent listing for “Christmas cactus” on platforms like Amazon often turns out to be a Thanksgiving cactus, adding to the overall perplexity.

However, with a little insight into their natural habits, these plants can thrive and burst into colorful blossoms. Soon enough, you might find yourself sharing cuttings from your cherished holiday cactus with friends and family – no need to be a grandmother, though it might not hurt.

Let’s Address the Most Common Issue

The frustration of Christmas cactus owners is often rooted in the plant’s failure to bloom during Christmas or, in some cases, not blooming at all. The key lies not in any inherent flaw with your plant but rather in its unique care requirements. Christmas cacti operate on their own schedule, dictated by daylight.

These plants are considered short-day photoperiod bloomers, meaning they set buds and bloom as the days grow shorter. Understanding this natural rhythm is crucial to solving the mystery of why your Christmas cactus might not be cooperating.

To comprehend how to care for them and encourage blooming, it’s helpful to examine their wild growth habits. Typically found nestled in tree crooks or on rocky surfaces, Christmas cacti are aroids, often epiphytic or epilithic, forming symbiotic relationships with their host plants. In their natural habitat in Brazil, these plants tend to be more scraggly and woody compared to the pampered specimens we keep in our living rooms.

All Christmas cacti belong to the Schlumbergera family, and while they may appear similar without blooms, a closer look reveals three distinct species associated with Christmas, Thanksgiving, and Easter.

Identifying the three species

  1. Thanksgiving cactus – Schlumbergera truncata
  2. Christmas cactus – Schlumbergera buckleyi
  3. Easter cactus – Schlumbergera gaertneri

The most prevalent variety in the United States is the Thanksgiving cactus, often seen in garden centers and home improvement stores around November.

Care tips for all types

Despite the differences in blooming times, all holiday cacti share similar care preferences, deviating from the stereotypical cactus requirements.

Light and Temperature

Holiday cacti thrive in bright indirect light, making an east-facing window an ideal location. They prefer temperatures between 60-75 degrees Fahrenheit and can be grown outdoors if nighttime temperatures don’t dip below 50 F, provided they are shielded from direct sunlight.

Watering

Contrary to the typical cactus image, holiday cacti resemble tropical plants in their watering needs. They prefer a good soaking followed by drying out between waterings. It’s crucial to use well-draining pots and avoid overwatering to prevent root rot. If your home is not naturally humid, placing the pot on a dish with pebbles and water can provide the necessary humidity.

Soil

Holiday cacti prefer a potting mix resembling their natural environment, where dirt and debris accumulate. Opt for a well-draining aroid potting mix or make your own using an African violet mix. These plants appreciate being slightly root-bound, requiring repotting only every few years.

Fertilizer

During their active growth period, feed holiday cacti with a balanced fertilizer, supporting new growth and encouraging new leaf segments. Adjust the fertilization routine based on the blooming season, focusing on phosphorus-rich fertilizers to promote bud development.

Blooming

To ensure annual blooms, mimic their short-day blooming behavior by exposing the plant to longer, cooler nights as days shorten. Keep the plant in darkness for 12-14 hours daily and maintain temperatures between 50-55 degrees Fahrenheit. Once buds appear, return the plant to its usual location, avoiding disturbances that may cause bud drop.

Propagation

After blooming, let the plant rest for a month or two before trimming if needed. Use the trimmed segments for propagation by allowing them to callous for a few days before planting them in fresh soil. Holiday cacti are relatively easy to propagate and share with friends and family.

Pets, Pests, and Problems

Holiday cacti are non-toxic to pets and generally resistant to pests. However, overwatering can lead to root rot, and adjusting watering practices is crucial if the plant appears unhealthy. Consider using breathable clay pots and maintain a balance of light and water to address potential issues.

Identifying Holiday Cacti

Distinguishing between Thanksgiving, Christmas, and Easter cacti involves examining their leaf segments and bloom shapes. Thanksgiving cacti have pointed teeth, Christmas cacti have notched sides, and Easter cacti feature rounded segments. Tube-shaped blooms characterize Thanksgiving and Christmas cacti, while Easter cacti have daisy-shaped flowers.

With proper care, your holiday cactus, whether it’s a Thanksgiving, Christmas, or Easter variety, can bring you years of beautiful blooms. These resilient plants are not only a joy to cultivate but also perfect for sharing with loved ones.
