The Thanksgiving cactus (Schlumbergera truncata) is a stunning indoor plant that adds color and joy during the cooler months. Its vibrant flowers and relatively simple care make it ideal for both beginner and experienced gardeners. In this article, we will explore the best care practices for the Thanksgiving cactus, its different colors, mature size, and the difference between it and the Christmas cactus.
What Does a Thanksgiving Cactus Look Like?
The Thanksgiving cactus is a succulent plant that belongs to the cactus family but is distinct in its flat, segmented, and flexible stems. Its segments form characteristic shapes resembling “bells” or “crabs,” so it’s often referred to as the crab cactus. Its flowers are spectacular, typically emerging in vibrant colors like red, pink, orange, white, and even purple. This cactus tends to bloom around Thanksgiving, making it a popular plant for holiday decorations.
How to Care for the Thanksgiving Cactus
Caring for the Thanksgiving cactus is relatively easy once you know its basic needs. Here are some tips to ensure its health and blooming:
- Watering: Unlike many other cacti, the Thanksgiving cactus prefers more frequent but moderate watering. It’s crucial not to let water sit in the pot, which can lead to root rot. Water the plant when the top of the soil is dry to the touch, but make sure excess water drains well.
- Light: This plant thrives in bright, indirect light. Too much direct sunlight can burn its leaves, while too little light can hinder blooming. An ideal spot for a Thanksgiving cactus is near an east or north-facing window with bright but soft light.
- Temperature: The Thanksgiving cactus prefers cooler temperatures, usually between 50°F (10°C) and 60°F (15°C) during the blooming period. To encourage bud formation, it is important to provide more relaxed conditions in the fall.
- Fertilizing: During the growing season (spring through summer), feed your cactus with a balanced fertilizer every two weeks. In the fall, reduce fertilizing to avoid disrupting the blooming cycle.
Pruning
The Thanksgiving cactus doesn’t require heavy pruning but can benefit from occasional trimming to maintain its shape and encourage denser growth. After blooming, trim any damaged or dead segments with clean scissors. Pruning also helps to remove weak branches, promoting more vigorous growth.
Propagating the Thanksgiving Cactus

Propagating the Thanksgiving cactus is relatively easy and can be done through cuttings. Here are the steps to propagate:
- Take a healthy stem segment, about 2 to 3 segments long.
- Allow the cutting to dry for 24 hours to prevent rot when planted.
- Plant the cutting in well-draining soil and water lightly.
- Place the cutting in a bright spot with indirect sunlight and wait for it to root, which may take several weeks.
How to Get the Thanksgiving Cactus to Bloom
To encourage blooming on your Thanksgiving cactus, give it a period of darkness before the bloom. Here’s how to proceed:
- Darkness: Expose the plant to darkness for 12 to 14 hours daily, ensuring it doesn’t receive any light during this time. This mimics the plant’s natural cycle in the fall and triggers bud formation.
- Cool temperatures: During this period, keep the plant at cooler temperatures, ideally between 50°F (10°C) and 60°F (15°C). These cooler conditions promote the development of flower buds and their subsequent bloom.
Common Problems with Thanksgiving Cactus
Although the Thanksgiving cactus has relatively low maintenance, it can face a few issues. Here are some common problems and how to address them:
- Root rot: Excessive watering is the leading cause of root rot. Ensure your cactus is in a well-draining pot and that water doesn’t sit in the saucer.
- Lack of blooms: If your cactus isn’t blooming, it could be due to too much light, too high temperatures, or a lack of darkness before blooming. Make sure to follow the darkness recommendations for triggering blooms.
- Pests: Like many indoor plants, the Thanksgiving cactus can be susceptible to mealybugs, aphids, or spider mites. If you notice pests, treat them immediately with an insecticidal soap.
Holiday Cactus Plants – Christmas Cactus Vs. Thanksgiving Cactus Vs. Easter Cactus – What’s the Difference?

Holiday cactus, including the Thanksgiving cactus, are often confused with the Christmas and Easter cacti. While these plants belong to the same genus, they have notable differences:
- Thanksgiving cactus: Blooms in the fall, with jagged and pointed segments. Its flowers can be red, pink, white, or purple.
- Christmas cactus: Blooms in winter, typically around Christmas, with rounded segments. Its flowers also come in red, pink, and other colors.
- Easter cactus: Blooms in the spring, with smooth segments and usually brighter-colored flowers.
All these cacti are similar in care, but they bloom at different times, allowing you to grow them for almost continuous blooms throughout the year.
Christmas, Easter, and Thanksgiving Cactus Watering Needs
All holiday cacti have similar watering needs, but here are specific tips:
- Moderate watering: Ensure the soil dries out slightly between waterings. Excess water can lead to root rot.
- Drainage: Use a pot with drainage holes to prevent water from sitting, which can harm the roots.
Holiday Cactus Light Requirements
Holiday cacti prefer bright, indirect light. Avoid placing them in direct sunlight, which can burn their leaves and affect blooming. A spot near an east or north-facing window is ideal. Also, be mindful of their need for darkness to encourage blooming.
Pro Tip
To ensure your Thanksgiving cactus blooms abundantly, provide a natural light-dark cycle. Reducing light exposure for about six weeks before blooming helps encourage flower development.
