Thanksgiving day is coming! If you’re like me, you’re probably excited about getting your Thanksgiving Cactus (Schlumbergera) to bloom just in time for the holiday season. There’s something magical about having a burst of vibrant flowers to decorate your home, especially when it’s chilly outside. But if you’ve ever struggled to get your cactus to bloom, you’re not alone. Many people face challenges when trying to get their holiday cactus (Schlumbergera) to bloom during the festive season. Don’t worry! In this post, I’ll share 5 simple tips to help you get your Thanksgiving cactus bloom, no matter if you’re a beginner or an experienced gardener.
When Does a Christmas Cactus Bloom?
The typical blooming period for a Christmas cactus is usually between November and January. However, the exact timing of its bloom largely depends on the plant’s exposure to light and temperature—factors you can control to help encourage its flowers.
Christmas cacti naturally bloom when they experience cooler temperatures and shorter periods of light. This is why they often flower during the chilly, dim days of early winter. By adjusting these environmental conditions, you can influence when your cactus blooms, making it easier to enjoy its beautiful flowers just in time for the holidays.
Why Isn’t My Thanksgiving Cactus Blooming?
Before diving into the tips, let’s first understand why your Thanksgiving cacti might not be blooming. If your plant isn’t flowering, it’s usually because of a few simple factors. These can include improper light, watering issues, or even the wrong temperature. But don’t worry — these issues are easy to fix!
Now, let’s take a look at the 5 easy tips that will help you learn how to make Thanksgiving cacti bloom beautifully for the holiday season.
1. Adjust Light Exposure to Encourage Blooming
One of the most important factors in getting your Thanksgiving cacti to bloom is light exposure. These plants are native to the cloud forests of Brazil, where they grow under the canopy, receiving indirect light. If you want your cactus to flower, it needs to be exposed to bright, indirect light.
Here’s how to make sure your holiday cactus gets the right amount of light:
-
Keep your plant in a well-lit spot but avoid direct sunlight, which can scorch the leaves.
-
If you’re growing your cactus indoors, placing it near a window with sheer curtains is perfect.
Tip: To trigger blooming, Thanksgiving Cactus needs around 12-14 hours of darkness each night for about two weeks before blooming. So, try to place your plant in a spot where it can get that long, uninterrupted dark period.
2. Control Temperature and Watering for Optimal Growth
Temperature plays a huge role in whether your Thanksgiving cacti will bloom. These cacti are used to cooler temperatures in the wild, so keeping them in a room that’s too warm can prevent flowering.
To encourage blooms:
-
Keep your cactus in a cool room, ideally between 60-70°F (15-21°C), especially as the bloom period approaches.
-
Watering is equally important. Overwatering can cause root rot while underwatering can stress the plant. Water your Thanksgiving cacti only when the top inch of soil feels dry to the touch.
Tip: Reduce watering slightly once you notice buds forming, as this can help the plant focus its energy on flowering rather than growing new leaves.
3. Fertilize Sparingly — Less is More
Fertilizing your Thanksgiving cacti is important, but it’s easy to overdo it. Over-fertilizing can cause the plant to produce more leaves rather than flowers. To help your cactus bloom, use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring to early summer).
Once the buds start to form, stop fertilizing completely. This will help your cactus conserve energy and focus on blooming.
4. Give Your Cactus a Rest Period
Did you know your Thanksgiving cactus needs a rest period before it will bloom? After the flowering season ends, your cactus will need a break. This rest period is crucial for blooming in the next cycle.
To give your holiday cactus the rest it needs:
-
Reduce watering and move the plant to a cooler, darker spot for about 4-6 weeks.
-
Avoid fertilizing during this time.
This rest period helps signal to the plant that it’s time to bloom once the days start getting shorter and temperatures cool down.
5. Avoid Overcrowding and Repotting
If your Thanksgiving cactus is becoming overcrowded in its pot, it may struggle to bloom. These plants prefer to be slightly root-bound, so repotting them too often can disrupt their blooming cycle. It’s best to repot your cactus only when the roots are filling the pot or every 2-3 years, whichever comes first.
Tip: If you notice your cactus has outgrown its pot, only move it to a slightly larger one. Too much space can make the plant focus more on growing roots than producing flowers.

Troubleshooting Common Problems
Even with the best care, sometimes your Thanksgiving cactus may face challenges that prevent it from blooming. Here are a few common problems and quick fixes:
-
Too much water: If your cactus is not blooming, it could be due to overwatering. Make sure the soil is well-draining and only water when the top inch of soil is dry.
-
Not enough light: Remember, Thanksgiving Cactus needs bright, indirect light. If it’s not getting enough light, the plant might not bloom.
-
Temperature issues: Keep the temperature in the ideal range of 60-70°F. Too warm or too cold can stress the plant.
Frequently Asked Questions (FAQ)
Q1: How long does it take for Thanksgiving Cactus to bloom?
Typically, Thanksgiving Cactus blooms within 6-8 weeks after starting the “dark period.” Make sure you provide the right conditions, and you should see flowers emerge from late fall to early winter.
Q2: Can I force my Thanksgiving cacti to bloom early?
Yes, you can trigger early blooms by adjusting the light and dark cycles. Provide the cactus with 12–14 hours of darkness for a couple of weeks to encourage blooming.
Q3: Should I prune my Thanksgiving cactus after blooming?
It’s a good idea to prune your cactus after it has finished flowering. Cutting back some of the longer stems will encourage new growth and more blooms in the following season.
Q4: What’s the best soil mix for Thanksgiving Cactus?
A well-draining cactus mix or a mixture of potting soil and perlite is ideal. This will help prevent root rot and keep your plant healthy.
