How can you grow a Thanksgiving cactus? What kind of potting soil do you use?
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.
Does a Thanksgiving cactus enjoy being confined by its roots?
After your new plant blooms, think about switching out the plastic pot for a new one, preferably made of ceramic so that kids and dogs can’t easily knock it over. Cacti cannot grow in damp soil, so make sure the pot has adequate drainage holes. Select a cacti-specific potting soil blend. Sand or peat moss should be present to prevent moisture from collecting and decaying the roots.
Transplanting shouldn’t be necessary more frequently than every two to three years because Thanksgiving cacti prefer to be root-bound. Some people get big, especially those who are passed down down the generations. They can resemble a favorite fireworks display in that they can be two feet wide and a foot tall with parts shooting in all directions!

What time of year is ideal for repotting cacti?
Cacti come in a wide range of colors, textures, and sizes for their flowers. Cacti can be divided into two primary categories: desert cacti (which are typically armed with spines) and jungle cacti (often without spines and most are epiphytes). You can have an interesting houseplant that is trouble-free and long-lasting if you choose the proper cactus for the right location.
When to repot
As soon as the roots start to peek through the drainage holes at the bottom of the pot, cacti need to be repotted. Fast-growing plants should typically be repotted every two to three years, whereas slow-growing species should be done so every three to four years. The optimum time to repot cactus is in the spring when they are actively growing. Two days prior to repotting, water the cactus to keep the roots moist but not soggy.
Do Thanksgiving cacti enjoy misting?
The Thanksgiving Cactus enjoys occasional mistings of water. These plants don’t require weekly watering, although sporadic watering and more regular misting are both highly beneficial to them.
When it blooms, should I water my Thanksgiving cactus?
A well-liked indoor plant with stunning, protracted-flowering winter blooms is Schlumbergera truncata.
The plant is simple to maintain and take care of. Discover some growing advice for the Thanksgiving cactus by reading on.
Sunlight and temperature needs for schlumbergera truncata:
Summertime light shade is ideal for Thanksgiving cactus growth. When it is blooming in the winter, you can give it extra sunlight.
In the summer, excessive sun can cause the leaves to seem pale and yellow. The leaves may turn scarlet with too much sun.
Ideal room temperatures range from 60 to 65 F. While the plant has buds on it, you should take extra precautions when it’s hotter outside.
I maintain my Thanksgiving cactus indoors in a South-facing window in the winter and outdoors in the shade during the summer.
Humidity and watering requirements for Thanksgiving cactus:
Watering is by far the most crucial part of Thanksgiving cactus maintenance. These tropical plants shouldn’t be allowed to dry out, but you also shouldn’t want them to accumulate too much water at the roots.
Because it is an epiphyte, the plant occasionally has exposed roots and draws hydration from the air’s humidity.
A Thanksgiving cactus can be watered effectively using the “soak and drain method.” Bring the plant to the sink and water it thoroughly, letting the water run out of the drain hole at the pot’s bottom.
Before you water again, let the top layer of soil completely dry out between applications.
Water the plant only as much as necessary to prevent shriveling when it is not in bloom. Keep in mind that plants can die from excessive watering.
This winter cactus shouldn’t be treated like a desert cactus! If at all feasible, plant Schlumbergera truncata in an environment with moderate to high relative humidity (above 50%).
Growing the plant in a tray with water underneath some pebbles and frequently misting it with a plant mister both help to increase the humidity.
Soil needs for Thanksgiving cactus:
When selecting soil for your Thanksgiving cactus, keep in mind their natural habitat. The plant prefers an acid soil because it typically thrives in tree fissures with decomposing debris nearby.
Rich, porous soil with lots of organic matter is what Schlumbergera truncata prefers.
How do I maintain the flowering of my Thanksgiving cactus?
Fertilizer. To encourage blooming in the fall, the Thanksgiving cactus should get frequent fertilization throughout the growth season. Every two weeks in the spring, summer, and early fall, apply a balanced, diluted liquid fertilizer.
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. One teaspoon can be added to one 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.
