Where should a Thanksgiving cactus be placed?
Light. Thanksgiving cactus thrives in mild indirect light in the spring and summer. Move it to a brighter area before it blooms in the fall, but keep it out of direct sunlight. The ideal location will provide bright, indirect light.
Should I mist my cactus of thanksgiving?
The most frequent queries regarding raising a Thanksgiving cactus are addressed here. If yours isn’t addressed here, post a comment below with your query.
How fast does a Thanksgiving cactus grow?
A Thanksgiving cactus can develop quickly. They can reach their full size of 24 in just a few years with the right care.
It might be time to repot yours if it is growing extremely slowly, or you could try fertilizing it in the spring and summer.
Are Thanksgiving cactus indoor or outdoor plants?
Depending on where you live, Thanksgiving cacti can grow as either indoor or outdoor plants. In areas where the winters are frigid, they are frequently kept indoors as houseplants.
When the nighttime temperature is over 50°F in the spring and summer, they can be moved outside. In zones 9 through 11, gardeners may leave them outside all year.
Should I mist my Thanksgiving cactus?
If the air in your house is particularly dry, you should mist your Thanksgiving cactus. Humidity is crucial because they absorb moisture from the atmosphere. However, after sprinkling, don’t leave water on the leaves for too long to prevent decay.
How often should I water my Thanksgiving cactus?
Only water your Thanksgiving cactus frequently enough to maintain equally moist soil. Avoid over-drying it out to prevent shriveling or drooping leaf segments. To prevent the roots from rotting, do not allow it to become so wet that there is standing water.
How much light does a Thanksgiving cactus need?
Thanksgiving cacti require 8 to 10 hours of indirect, strong light each day, with 12 to 16 hours of total darkness in the early fall to stimulate flowering. They thrive outside in locations with dappled sunlight or partial shade.
It’s crucial to learn about Thanksgiving cactus maintenance so you can consistently enjoy the stunning, vibrant flowers. You’ll be able to raise Schlumbergera truncata for many years if you get the hang of it.

Does the Thanksgiving cactus need to be in the sun?
Temperature & Light: The festive cacti thrive in bright shade. In the fall and winter, full sunshine is advantageous, but in the summer, intense sunlight can cause plants to seem pale and yellow. In the growing season from April to September, temperatures between 70 and 80 F are ideal for spring and summer growth. The Thanksgiving and Christmas cacti need on shorter (8 to 10 hour) days and cooler temperatures in the fall to develop their flower buds. Once the flower buds are set in the fall, do not allow the temperature to reach above 90 F. The loss of flower buds can be a result of persistently warm conditions. In the event that it gets below 50 degrees Fahrenheit, do not leave these cactus outside.
Temperature control and photoperiod (control of the duration of the day and night) control are key factors in successful flower bud formation in the fall. The plants require the following for the initiation of flower buds:
- dazzling light
- long evenings Before flower buds to set, there must be at least 14 hours per day of nonstop darkness. For a full bud set, long nights should begin around the middle of September and last for at least six weeks. Be aware that even two hours of intermittent lighting can prevent flower buds from setting. In 3 to 4 weeks, buds will often start to appear. Once the buds are set, the photoperiod has little impact on flowering.
- For optimal flower production, fall growth temperatures should be kept between 60 and 68 oF, ideally as close to 68 oF as feasible. Regardless of the length of the day, plants cultivated with night temperatures between 50 and 59 oF will produce flower buds, however growth will be slower and bud drop may happen at this temperature.
- Early in June, prune the stems to encourage branching and additional flower terminals.
- At the end of September, pinching—also known as leveling—is done to cut off any terminal phylloclades that are less than 1 cm (0.4 inch) and to roughly equalize the length of all stems. These young, immature stem segments won’t begin blossom buds until they are fully developed. A flower bud develops on the earlier, more developed stem segment following the removal of a brief phylloclade.
Fertilizer and Watering: Water the growing media until it feels completely dry to the touch. The spring and summer months can be dry and mildly underwatered for the holiday cacti. Avoid letting the soil become soggy, especially during the gloomy winter months, but also avoid letting it fully dry up. To avoid flower bud abscission, the growing medium must be kept consistently moist after bud set in the fall. In the saucer underneath the pot, never let water stand.
Use a half strength soluble fertilizer, such as a 20-10-20 or 20-20-20 with trace elements, to fertilize plants every month beginning when new growth begins in late winter or early spring and continuing through the summer. Compared to many plants, holiday cacti have a greater magnesium need. During the growing season, fertilize once a month with Epsom salts (magnesium sulfate) blended at 1 teaspoon per gallon of water, but avoid applying the fertilizer the same week. Stop fertilizing in the late summer to increase the formation of bloom buds in the fall.
The Christmas cacti flower best when kept fairly pot-bound, according to the growing medium. Repotting is best done in the spring and is only required about once every three years. These epiphytic cacti do not grow well in heavy, wet potting mixes, thus the potting medium needs to be well-drained and well-aerated. A excellent mixture can have 60–80% potting soil and 40–20% perlite. Pick a potting soil that is pH balanced and of good quality.
Why are my Thanksgiving cactus’ limp leaves?
Lack of water or much sunlight can occasionally result in wilted or weak Christmas cacti. Start by giving the wilting Christmas cactus a small amount of water if you haven’t been watering it. Every few days, continue to water carefully until the soil is barely damp.
Christmas cactus issues can also result from excessively damp soil. The Christmas cactus cannot tolerate wet roots since it is an epiphyte in its natural habitat on the ground of tropical forests, where it takes moisture and nutrients from the air. The roots of Christmas cacti can become excessively wet and floppy because to poor drainage.
Move your wilted or limp Christmas cactus to a location with more shade, especially in the afternoon, if the leaves look dried or burned.
How can you tell if a Christmas cactus is overwatered?
Overwatered stems will appear mushy and limp. If the roots are getting dark and mushy, remove the plant from the ground and check them. If so, the plant is badly overwatered and has root rot.
Do you water a Christmas cactus from the top or bottom?
A smart approach to prevent water from sitting on the stem and rotting is to water your plant from the bottom.
Pick a pot with lots of drainage holes if you want to do this. For 30 minutes, place the pot in a bowl of water. Remove any extra water, then reposition the plant.
Temperature problems
Holiday cacti may experience shock and lose their leaves in response to significant temperature swings. Always keep them inside during the winter and keep them away from drafts.
Is Epsom salt good for Christmas cactus?
Epsom salts give your plant magnesium, which Christmas cacti love. You can mix 1 teaspoon per gallon of water. Use without fertilizer To prevent fertilizer burn, only use one or the other at once.
Should I repot my Christmas cactus?
Your holiday cactus has to be repotted every year or two, just after the blooms have finished. Pick a pot that is 2 inches wider across!
Your plant might benefit from new nutrients in new soil rather than needing a bigger pot. Pull it out of the pot gently, remove as much soil as you can, and then repot it in the same pot with new soil.
