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 favourite fireworks display in that they can be two feet wide and a foot tall with parts shooting in all directions!
How can you recognise a rootbound Christmas cactus?
Do Christmas cacti enjoy being rootbound? I was told not to repot it because it is currently healthy. D. Forrest
SUMMARY: Christmas cactus tolerates dense root systems well, so your friend isn’t entirely mistaken. Although Christmas cacti can still thrive after becoming rootbound, you should still repot your holiday plants every four years, expanding the container size by two inches each time.
Repotting a Christmas cactus can be difficult since, if the plant becomes rootbound, doing so might easily cause damage to the plant. Breaking the pot is the quickest way to remove it without harming the plant. It’s not a major loss because clay pots are inexpensive, and it’s much simpler to rehome your cactus without harming it.
If you notice your planter’s soil getting harder over time, observe roots poking out of the drainage hole or holes, or notice that the stems of your Christmas cactus are beginning to turn yellow or brown, your cactus may be root-bound (the latter symptom is also sometimes a sign of overwatering, not overcrowding). If you see these symptoms, you can leave your plant in its overcrowded container for a few more weeks or even months because it actually prefers the crowding. But ultimately, you’ll want to repot your cactus to give it more space and, in the process, provide it with newer, healthy soil.
To speed up water drainage, use potting soil designed specifically for cactuses and succulents. Fill the new, larger replacement planter with enough fresh soil so that the top of the root ball will rest about an inch below the rim. Remove a significant amount of the old soil from the roots and root ball by gently brushing off the root ball. To remove the majority of the oil soil from the roots and root ball, you can choose to wet or rinse them with water.
Then, carefully fill the space surrounding the root ball with the new, fresh potting soil that was designed for desert plants after placing your cactus in its new pot. While repotting, take out any stems that have yellowed or dried out. When the new dirt is securely planted, water your Christmas cactus thoroughly and choose a shaded location to put it for a few days so that it can get used to its new surroundings, the new soil, and the extra room.
During the spring and summer, keep your cactus in a shaded area of the porch or patio where they can receive plenty of fresh air and indirect sunshine. If you prefer, you can take a few cuttings each fall and give them out as gifts once they have grown. Bring them indoors in the fall and store them away from direct sunlight in a dry, dark area. Your Christmas cacti will thrive exceptionally well if you can create a slightly humid indoor environment.
Start drying the soil in October to promote blooming during the holiday season. Reduce the frequency of watering to only once every three weeks instead of once a week. For holiday blooms to flourish, darkness and dryness are both necessary conditions. To enhance the flowering of their Christmas cacti, some gardeners go so far as to cover their plants and keep them in the dark for a few weeks.
Why is my cactus of thanksgiving wilting?
Root- or stem rot at the plant’s base is the likely cause of your plant’s stems falling off. Always, overwatering is the cause of this.
Care: Adhere to the suggestions listed under “Wilted or Shriveled Leaves” (Problem #2, Care #1) for over-watering. This will outline the proper way to take care of a plant that has received excessive water.
How often should you repot a Christmas cactus?
The best time to repot most plants is in the spring when they start to show new growth, but Christmas cacti should be potted after blooming is finished and the blooms have faded, which is in late winter or early spring. It is never a good idea to try to repot the plant when it is in full bloom.
Repotting Christmas cactus should be delayed because this tough succulent thrives when its roots are little congested. Frequently repotting a plant might harm it.
Repotting Christmas cactus is typically sufficient every three to four years, but you might wish to hold off until the plant starts to appear worn out or you see some roots poking through the drainage hole. A plant can frequently flourish happily in the same pot for years.
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.
What kind of soil works best for a Thanksgiving cactus?
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 equalise 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 fertiliser, such as a 20-10-20 or 20-20-20 with trace elements, to fertilise 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, fertilise once a month with Epsom salts (magnesium sulphate) blended at 1 teaspoon per gallon of water, but avoid applying the fertiliser the same week. Stop fertilising 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.
