The holiday cacti thrive in their natural home among the tall tree branches, living in crevices filled with rainfall and decomposing organic materials. Christmas cactus care for outdoors is rather easy if you move your plant outside for the summer. Keep it shaded and water it when the soil’s surface feels dry. It has either had too much sun or not enough water if the leaf segments turn crimson. It could be deficient in phosphorus in some circumstances.
Bring your cactus indoors as October approaches and the weather begins to cool off. They can withstand brief durations of below-zero temperatures, but not freezing conditions.
The cactus are all short-day vegetation. To generate blossoms, they require 14 hours each day of uninterrupted darkness. Put the Christmas cactus on this light/dark cycle on October 1, the Easter cactus on January 1, and the Thanksgiving cactus on September 1. You can bring the cacti back into regular light after flower buds start to emerge, which should take four to eight weeks.
Temperatures play a role on the cacti’s ability to bloom. The cactus will also bloom if kept at 55 to 60 degrees Fahrenheit at night and 60 to 70 degrees during the day if you’re unable to maintain complete darkness for 14 hours each day. Avoid placing the plant near heater vents and in direct sunlight, since these factors might cause the buds to dry out and fall off.
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.
Can Christmas cacti survive the winter outside?
Can you grow Christmas cacti outside? The answer is true, but as Christmas cactus is unquestionably not cold hardy, you can only grow the plant outdoors year round if you reside in a warm environment. Christmas cactus can only be grown outdoors in USDA plant hardiness zones 9 and up.

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 fertiliser 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 fertilising 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 fertiliser every other week. In the new year, good luck with your interior and outdoor horticultural projects, including your Christmas cactus.
What degree of indoor temperature is appropriate for my cactus?
Moving your cactuses to a cool location is the second stage in winterizing them (allowing them to become dormant). When temperatures begin to drop around the middle of October, you should consider relocating your cactus to a cooler location.
The ideal range for cactus dormancy temperatures is between 47 and 54 °F (8-12 Celsius). If your cactus has spent the entire year indoors and you have heating, you should transfer it to a balcony, garage, or even outside. In the winter, you must avoid keeping your cactus in a warm or hot room.
You may prevent your cactus from falling dormant in the winter by not transplanting them to a cool place. It will go on expanding (but growth will be uneven and minimal).
In addition, the increased temperatures will cause the water to evaporate, which will cause the air to dry (as you will water it less). Additionally, it should be a dry area. Your cactus will thereafter develop thin, elongated growth.
Lower temperatures will slow down your cactus’s metabolic processes and reduce water evaporation. Growing throughout the winter will impede the development of flower buds, result in nutritional depletion, and lead the cactus to dry out.
Step 3: Keep your cactus in cool conditions for winter
Keep your cactus in the cool spot you’ve chosen until the end of February. Your cactus will be dormant and its growth will have stopped. Keep them where they may receive the most winter sun possible.
You should gradually acclimate your cacti to sunshine circumstances once the temperature starts to rise once more. But you have to do this gradually.
Your cactus are prone to burn in sudden sun because they won’t get bright, sunny conditions all winter. Cacti adjust to low light levels, therefore it’s crucial to reintroduce them gradually. Additionally, avoid fertilising your cactus during the winter.
Your cactus won’t actually show any signs of dormancy. But stagnation results in dormancy.
Step 4: Slowly introduce to sunny conditions
You must gradually acclimate your cacti to sunlight after the winter dormancy phase, around March, to avoid sunburns. Put them on a windowsill or another permanent/usual location to do this.
Then, protect your cactus from direct sunlight by using a thin white cloth or gauze. You can expose your cacti to more and more sunlight as the weather warms up over the course of a few weeks to a month.
Your cactus will burn if you don’t protect it from direct sunlight after a winter of little to no sunlight. A cactus’ epidermal tissues will be affected, which could result in death or interruption of vital metabolic processes. Additionally, be sure to give adequate ventilation because cacti detest stagnant air.
If you have recently re-potted your cacti into new containers, please minimise sun exposure and watering for a week. Additionally, don’t increase watering too quickly—increasing it gradually as the temperature rises. Your cacti’s successful dormancy will be ensured by gradual modifications in the surroundings.
Temperature
Due to the fact that some species of cactus are native to freezing desert environments, they can withstand temperatures as low as 20 degrees below 0 degrees Fahrenheit. These plants may exude water, which will give them a slightly deflated appearance, or they may contain spines or hairs that deter frost. However, many cacti cannot withstand cold or temperatures below zero. Always examine the hardiness zone of a cactus before purchasing. Bring your cactus inside as a houseplant if you reside in a location outside of its range. Row covers, tents, and frost cloths can all be used to protect your cactus from the bitter cold outside.
Humidity
To review, humidity is the quantity of water vapour in the atmosphere. Cacti typically like low humidity and good airflow, though they do appreciate water after drying up. Winters are frequently dry, so keeping your cactus next to a heater inside won’t cause any issues. The air outside is frequently dry due to wind chill. Keep an eye on the humidity if you live somewhere where it gets cold and humid. If the relative humidity exceeds those ranges, you might wish to bring your cactus indoors because most cacti like a relative humidity of 40 to 60 percent.
How should a Christmas cactus be cared for during the winter?
Christmas cacti require direct, strong sunlight. If you’re placing yours indoors near a west or south-facing window, make sure the light is shaded with a sheer curtain because they will burn in direct sunlight. If your home is dry inside in the winter, put it on a tray of stones or put it close to other plants because they need humidity.
Never let them sit in water; only add water when the top feels dry. Christmas cacti prefer temperatures between 65 and 70 degrees during the day and 55 to 65 degrees at night.
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.
Do Christmas cacti benefit from coffee grounds?
During the growing season, give your cactus fertiliser with potassium, nitrogen, and phosphorus once or twice a month. It is simpler to feed a plant when the fertiliser dissolves in water. Epsom salts can also be administered to it (more about this in a moment).
Do Christmas Cactus Like Coffee Grounds?
As much as you do, your Christmas cactus will appreciate a cup of joe. Potassium and nitrogen, two nutrients the cactus needs to be healthy, are abundant in coffee grounds.
Spread the grounds out to dry first before using them because wet grounds might get mouldy if used immediately. Give your plant its daily dose of coffee by either dispersing the dried grinds on the soil or blending them with water. Use this method to fertilise your cactus no more than once every two weeks.
Is Epsom Salt Good For Christmas Cactus?
Your Christmas cactus will, in fact, enjoy some Epsom salt. It’s an excellent approach to guarantee that the plant receives all the magnesium it requires to flourish and expand. One teaspoon of salt should be added to one gallon of water when mixing the salt and water. As it only requires fertiliser and food during the spring and summer growing seasons, stop feeding it in the fall.
