Light: Bright, indirect light is preferred by plants indoors. Place next to a window, yet out of the way of the sun. Place plants outside in a shaded area throughout the summer. Before the first frost, bring indoor plants back inside.
Water: While not waterlogged, Christmas Cactus prefers damp soil. Stop watering for 30 days after blossoming. When you notice fresh growth, start watering again.
Potting soil should have good drainage. Mix 3 parts potting soil to 1 part sand, or 1 part fir bark to 1 part potting soil.
Christmas cacti prefer a humidity level of 50 to 60 percent. Put the pot on top of the wet pebbles in the dish. Pot shouldn’t be submerged in liquid.
Christmas Cactus needs cold, 60–65°F days and 45–55°F nights to develop bloom buds. Keep your plants away from fireplaces, heating ducts, and chilly drafts.
Fertilizer: Applications of all-purpose fertilizer are beneficial to Christmas Cactus that are growing and flowering. Observe the manufacturer’s guidelines. Plants should not be fertilized during the 4-6 week resting period that follows when they finish blooming. Fertilizing should resume when plants start to produce new growth.
Pruning: After a time of rest, prune plants to promote the growth of new branches. When a plant is in bloom, pruning should not be done.
What temperature is too low for Christmas cacti?
The Christmas cactus can handle temperatures as high as 50 F, but it does respond better to milder temps in the fall when it is starting to form bloom buds. If the plant is exposed to excessive heat or light, no buds will grow. The largest number of blooms are produced during the winter blooming season when temperatures are kept between 60 and 68 F and 14 hours of total darkness are provided every night for six weeks starting in mid-September. To assist the blooms last as long as possible over the winter, keep the temperatures lower.
What degree of cold is too cold for cacti?
If you have enough light, cacti are some of the most rewarding houseplants. Few blooms can match them in terms of color, size, or beauty. Space is typically not an issue because most cacti grow slowly. They are extremely resilient and flexible. They do not “thrive on neglect,” unlike what the general public thinks. They “thrive on gentle loving care, like most plants, but they will at least “survive on neglect.”
Except for epiphytic (tree-dwelling) cacti and succulents like the Christmas cactus, rhipsalis, and orchid cacti, which demand less sunlight, greater humidity, and more watering than other species, the general care instructions below apply for cacti and most other succulent plants. They also prefer fertilizer with a higher nitrogen content. Compared to other species, add less sand to your potting mixture. Other succulents such as haworthias likewise favor brilliant indirect light over direct sunlight.
Light
Give cacti and other succulent plants the brightest or most sunny windows you have indoors (four to six hours of direct sun). They will grow abnormally long and thin in low light conditions. Your plants will benefit greatly from spending the summer outdoors in the morning or late afternoon sun, when there is greater air movement and light. The majority of succulents can withstand intense outdoor sun, but they must get used to it. When putting plants outside, place them in partial shade or shadow at first and gradually expose them over the course of a few weeks to the strong late spring and summer sun.
Spiny and woolly species need the greatest sunlight, whilst spineless species typically need shade during the midday hours. If your plant has a reddish tint, it may be because the amount of sun it can withstand is reached or exceeded.
Watering
When you water, make sure to water well and wait until the soil has dried before doing so again. In particular, succulents are vulnerable to rot from excessive watering. If the earth around your plant is already moist, NEVER water it. Pots that are dry weigh less than wet ones. When the soil inside clay pots is moist, they feel chilly and damp to the touch. When the soil has enough moisture for the plant, succulent leaves are solid and plump.
The majority of cacti and several other succulents prefer to maintain a significant amount of dryness during the cooler months of the year (usually October through April). Over this time, drink less water than usual. To encourage new growth in the spring, spray your plants in the early morning hours of warm days. The spines of plants will allow them to absorb moisture. In order to prevent new roots from being stifled by excessively damp soil during the early spring, we also advise watering plants from the bottom of the pot. Fill the plant’s saucer with water, give the soil, pot, and plant around 30 minutes to absorb the moisture, and then drain the extra.
If you embed your plants in a mixture of 50% coarse builder’s sand and 50% peat, they will grow to their fullest capacity if they are in clay pots. This stops the soil from drying out too quickly and enables the roots to grow in the consistent wetness that the peat/sand mixture creates. Make sure there is excellent drainage in the tray that contains the peat/sand mixture.
Temperature
Keep succulents and cacti above freezing in the winter. Some plants require a temperature range of 35 to 40 °F at night (some cacti and other succulents can endure temperatures well below freezing if kept absolutely dry.) A minimum temperature of 50–60 degrees is preferred for more tropical succulents like adeniums, euphorbias, lithops, and stapeliads.
Plants need to be shielded from intense heat in the summer since potted plants’ root systems are more susceptible to harm. Good air circulation and cautious watering will prevent fungal and rot issues in humid and hot conditions.
Fertilizer
From May to September, feed your plants once per month using a fertilizer that contains low nitrogen (10% or less), such as 5-10-5 or 10-30-20. Nitrogen overload promotes excessively quick green but weak development. As the majority of cacti have evolved to thrive in nutrient-deficient soils, always dilute the fertilizer more than the label recommendations suggest.
Repotting
In the spring or early summer, repotte. When young, most plants like annual repotting with just one pot size increase. Without relocating the plant to a larger pot, you can carefully remove the top inch or two of soil after you reach roughly a 6-pot size and replace it with fresh mix. Since succulents are typically heavy plants, especially when potted in clay, moving them into ever bigger containers can be challenging.
Steer clear of soils that contain a lot of peat moss. Peat retains moisture for too long and is difficult to remoisten after being fully dried (a frequent occurrence with most succulents). You can add some coarse builder’s sand to the soil to promote drainage and a tiny amount of peat to the soil to improve texture. As much as 40% sand is appreciated by stapeliads, wooly cactus, and lithops (living stones). The base of the plant should have a top dressing of fine gravel since it encourages greater water absorption into the soil, shields it from excess moisture, and looks good too. For every 3 inches of pot size, add a tablespoon of gypsum and bone meal, if possible.
Use a pair of wooden tongs or a piece of newspaper that has been rolled up to help plants with a lot of spin out of their pots. If the plant is resistant, resist the urge to pull it out because doing so will harm the roots. Try again by striking a hard surface with the pot. As much soil as you can take out without harming the root ball. To prevent rot, always repot the plant at or higher than the prior soil level. You might need to stake species of columns. To give new root hairs time to grow after repotting, wait a week or two before watering.
My Christmas cactus may I bring inside?
The common Christmas Cactus (Schlumbergera bridgesii), which blooms in the winter, is a lovely complement to almost any interior space. It is a superb contender for holiday gift giving because it is not only simple to maintain but also easily multiplies. Let’s examine how to grow and maintain a Christmas cactus.
Why are my Christmas 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.
Can a cactus be left outside in the winter?
The resilient cactus are easily able to live in locations with a lot of snow cover. Cacti can get burnt or frostbitten in locations with strong winds, sun, and little snow. As late in the growing season as feasible, carefully wrap the plants in burlap to prevent damage.
How chilly is 40 degrees for a Christmas cactus?
Holiday cacti are common indoor plants with the name of the holiday in bloom. Around the winter, Christmas cacti typically bloom with vivid, abundant pink blossoms. They can only be grown outdoors in zones 9 to 11 according to the United States Department of Agriculture. Can Christmas cactus survive extreme cold? Christmas cacti are more cold-hardy than other cacti, but they are tropical. Frost is intolerable to them, but low temperatures are necessary to force blossoms.
Christmas cacti prefer warm, balmy temperatures, moderate to low amounts of moisture, and strong sunlight because they are tropical plants. Although it enjoys warmth, you should keep the plant away from sources of severe heat or cold, like heaters and fireplaces. Temperatures between 60 and 65 degrees Fahrenheit are ideal at night (15-18 C.).
Place the cactus in a cooler location in October where the temperature is around 50 degrees Fahrenheit to force flowering (10 C.). Avoid rapid temperature changes once the plants are in bloom since they can cause Christmas cacti to lose their blossoms.
Taking the plant outside in the summer, first in a spot with dappled light and protection from any wind, is entirely acceptable. Christmas cactus cold damage is likely if you leave it outside for an extended period of time in the fall.

A robust Christmas cactus in full bloom makes a wonderful present or decoration, despite the fact that poinsettias continue to be the most widely used holiday plant. Christmas cacti may be cultivated year-round indoors and require little maintenance. The flowers come in a variety of hues, including combinations of yellow, salmon, pink, fuchsia, and white.
A Christmas cactus should be placed in a sunny area of the house when it is moved to its permanent location. The best light comes from a window facing north or east. If you wish to grow it inside, shade the plant with thin curtains in a south or west window.
The leaves of the Christmas cactus, a succulent plant, can hold a respectable amount of water. It is not, however, as drought-tolerant as you might imagine. When you can feel the top half of the growth mix feeling dry to the touch, water well. The amount of time between watering depends on the relative humidity, air temperature, amount of light, rate of development, and temperature of the soil.
For the Christmas cactus, humidity is crucial. Put the container on a pebble tray. To improve the humidity around the plant, keep water in the tray. Maintain the plant in this manner until it has finished blooming.
After blossoming is finished, give the plant six weeks without water to rest. Resuming watering after that will keep the soil relatively moist while allowing the top to dry off. Transfer the plant to a new container as necessary as springtime tender growth emerges, or top-dress with new growing medium. For Christmas cactus, potting soil that drains well is essential. For succulent plants, use potting soil that has been professionally packed. Every two to three years, or whenever the container is full of roots, plants need to be replanted. Any time of year is a good opportunity to repot plants that seem unwell. Every two to three weeks, use a liquid houseplant fertilizer at half the recommended rate as a follow-up.
In the summer, Christmas cacti can be put outside, but they need to be tended in a partially to completely shaded area. The leaves can burn in direct sunlight. For the summer, some gardeners relocate their plants to a porch or patio with shade. After the growing mix dries on top in the summer, water it to keep it moist.
After making sure no insects are accompanying the plant, bring it indoors when fall arrives in September. Most insects that attempt to board are usually driven off by a stream of water sprayed in their direction. Like before it went on vacation outside, put the Christmas cactus in a sunny spot. High light intensity is essential for the development of flowers.
Water simply enough during fall maintenance to keep plants from withering. Before watering, let the top half of the potting mix dry out. The pebble tray with water for humidity should not be forgotten. Don’t water the plant in October unless it starts to wilt. In November, you can slowly start watering again. Branches droop and snap when they are overwatered. When the growing mix’s top dries off, add water.
Although the Christmas cactus is simple to grow, some claim that it can be challenging to get it to bloom once more. Cool temperatures are necessary for flowering even though warm temperatures are beneficial throughout the growing season. Keep the plant somewhere where the temperature is between 60 and 65 degrees starting in October. Keep Christmas cactus away from fireplaces, heat vents, and other heat sources. Flower buds will grow if temperatures stay in this range for a period of six weeks.
If you are unable to maintain temperatures in this range, you must provide the plant with 13 hours of continuous darkness every night to trigger flowering, which should begin around the first of October. Every night, put the Christmas cactus in a room that is entirely dark, or cover it with a box or dark piece of clothing.
Stop fertilizing and only water enough to keep the leaves from drooping throughout the period of flower bud production, which begins in October. Water the growth mix when the top half becomes dry to achieve this.
Once the Christmas cactus develops buds, nurture it in a room with typical indoor temperatures and medium to high light. Water the plant to keep it evenly moist when the growing medium’s top dries out. Give your Christmas cactus a half rate of liquid houseplant fertilizer every other week. In the new year, good luck with your interior and outdoor horticultural projects, including your Christmas cactus.
