Origin: Native to Southeast Brazil’s rainforests and coastal highlands; found in nature adhering to trees and rocks rather than growing in soil.
Growth rate and size: Within a few years, it can attain a spread of 2 feet. Cactuses for Thanksgiving and Christmas can endure for years, even decades.
Flowers: Fuchsia (the most frequent) and pink, red, white, or yellow are among the many colors available.
Toxicity: The fibrous plant material can cause gastrointestinal irritation in dogs and cats, but it is not poisonous to them.
Do Christmas cacti grow fast?
Christmas cactuses, unlike many other plants, never cease growing and have no maximum size. Every year, Christmas cactuses sprout new segments to their branches. The number of new segments produced is determined by the growth conditions. Within a few years, they can easily achieve a spread of 2 feet. The cactus can grow to be quite enormous as it gets older. Christmas cactuses can be pruned to keep them at a manageable size by pinching off branches between growth segments.
Repot the slow-growing Christmas cactus in a pot that is half the size of its current container. Make sure the new pot has drainage holes in the bottom and is just big enough to hold the cactus’ width and roots. Remove the plant from its current container and shake the potting mix off. Fill roughly half of the bottom of the new pot with cactus potting mix or 2 parts potting soil to 1 part vermiculite or sand. Equal parts potting soil, leaf mold, and sand make up another potting mix option. Place the Christmas cactus in the pot and fill the remaining space with any potting mix you like. Because that type of cactus operates best when pot-bound, a pot that is too large for a Christmas cactus can inhibit the plant’s growth.
How long does it take for a cactus to grow full size?
If you own a cactus, you’ll want to know how quickly it grows and how big it gets over time. This is important to know so you can plan where you’ll put your cactus and what plants you’ll grow alongside it. So, how quickly does a cactus grow?
Depending on the species, most cactus grow slowly, sprouting to the size of a large marble after 6-12 months and reaching a height of a few centimeters after 2-3 years. Most cacti grow 1-3 cm in height per year after that. There are a few notable exceptions, which can reach a height of up to 15 cm every year.
- The Golden Barrel Cactus, for example, grows 1-2 cm in height per year on average.
- The Saguaro Cactus (Carnegiea gigantea) can reach heights of 75 feet and grows 2-15 cm every year, depending on the growth stage.
For most cactus species, getting your cactus to full size will be a waiting game. We’ll provide you a growth timeline as well as some recommendations on how to accelerate growth in this article. Continue reading!
How can I make my Christmas cactus grow faster?
From early November to late January, then from early April to late September, water the soil from one to two inches deep anytime it feels dry to the touch, giving it a good drink each time. Reduce watering to one a week from late January to early April and late September to early November.
Every four years, Christmas cacti must be repotted. Each time you repot your cacti, increase the size of the planter by two inches. If your cactus isn’t growing as quickly as you’d like, try placing it in a smaller container. Changing your potting soil may also aid in the growth of your cactus. Make a potting soil mix using equal parts sand, leaf mold, and commercial potting soil.
Water your Christmas cactus with an epsom salt solution to fertilize it. Mix one teaspoon of epsom salt with one gallon of water to make the solution. From the first week of April to the first week of September, apply this fertilizer once a month. You can also use a water-soluble all-purpose 20-20-20 fertilizer, which you can make by mixing a half teaspoon with one gallon of water and feeding once a month from April to September. You can alternate these fertilizers, but don’t use both at the same time and only feed once a month.
The temperature of the air, whether inside or outside your home, is also vital for your Christmas cactus to thrive. Maintain a temperature of 60 to 68 degrees Fahrenheit for your cactus during the fall and winter months. Cacti should be kept between 70 and 80 degrees Fahrenheit in the spring and summer, but never above 90 degrees Fahrenheit. During the fall and winter, holiday cactuses should not be exposed to more than eight to ten hours of bright light every day, as they require additional time in the dark to begin flowering for the holiday season.
How often should you water a Christmas cactus?
- Water every two to three weeks, but only until the top one-third of the soil feels dry to the touch. Water when the top 2 inches of soil feel dry, for example, if the plant is in 6 inches of soil. (Check with your finger!)
- Soak the soil until water runs through the drainage holes in the pot when it is suitably dry. To catch the water, place a tray underneath the pot. Remove any extra water from the tray after 10-15 minutes so that the pot does not sit in water.
- Feed every two weeks with a balanced houseplant fertilizer from spring through early fall. Feed the cactus once a month in the fall and winter to encourage blooming.
- Late in the spring, prune plants to encourage branching and more flowers. Simply cut a few portions off each stem, and the plant will branch out from the wound.
- Place the cut pieces in a gently wet potting soil if desired; they will root easily after a few weeks and make great Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The lower temperatures and longer evenings of autumn bring out the blooms of Christmas cacti and its relatives. This is the general blooming schedule for the three main species of Christmas cacti:
- Thanksgiving cactus are the earliest and most persistent bloomers, blooming from late October to mid-winter.
It’s possible that your cactus isn’t flowering because it’s getting too much sunshine or being exposed to too hot temperatures. Here are some pointers to help you get yours to bloom!
- For at least six weeks, nights must be at least 14 hours long and days must be between 8 and 10 hours. If you have powerful interior lighting that is turned on at night, you may need to cover your cactus or transfer it to a location where it can be exposed to natural light.
- Flower buds form best when the plant is kept between 50 and 60 degrees Fahrenheit (10 and 15 degrees Celsius).
- By exposing the plant to temperatures of around 45°F (7°C) for several nights in a row, you can jumpstart the budding process.
- Ensure that you water the plant on a regular basis when it is in bloom. If the plant dries out too much, the buds may fall off.
- Don’t worry if the cactus loses its buds throughout the winter; it will bloom the next year!
How many times a year does a Christmas cactus bloom?
Is It Possible For A Christmas Cactus To Bloom More Than Once A Year? Yes. Christmas cactus, unlike many other succulents, can bloom again in the spring if given the right conditions.
How long will Christmas cactus live?
With good cause, the Christmas cactus may be found all over throughout the holiday season. It’s a blooming succulent that’s easy to care for, has beautiful blossoms, and may survive for up to 100 years if properly cared for! That’s correct! This plant can last for decades, giving your holidays a splash of color for generations. That’s a fairly good return on investment for a plant as simple and low-maintenance as the Christmas cactus!
Do you water a Christmas cactus from the top or bottom?
Remember that Christmas cactus plants demand moist soil rather than the dry dirt preferred by most other succulents. When the top inch or two of soil on a Christmas cactus is dry, water it. Fill the pot saucer with stones and water to just below the tops of the pebbles (the pot should not be sitting directly in water) to assist improve the humidity around your plant. As the water evaporates, the air will become more humid. (See below for watering suggestions if you’re attempting to get your Christmas cactus to rebloom.)
How do you perk up a Christmas cactus?
Repot the Christmas cactus into fresh soil when it is extremely limp and the soil is moist. Remove the wilting Christmas cactus from its pot and gently scrape away as much soil as you can. Make your own repotting soil to avoid future Christmas cactus issues. Use two parts potting soil to one part sand or vermiculite in a top grade potting soil to ensure sharp drainage.
How do you know when to repot a Christmas cactus?
Christmas cactus repotting should be done after blooming has ended and the blooms have withered in late winter or early spring, when most plants are best repotted when they show new growth. When the plant is actively blooming, never try to repot it.
Repotting a Christmas cactus isn’t necessary because this tough succulent thrives when its roots are little congested. Repotting the plant on a regular basis can harm it.
