Fertilize the plant every month after it has bloomed, starting when you see fresh growth at the end of winter or the beginnings of spring. Feed a Christmas cactus with a 50 percent strength 20-20-20 or 10-10-10 plant food diluted with water. Apply a monthly application of a magnesium sulfate solution at a ratio of 1 teaspoon to 1 gallon of water to the plant, but not the same week you apply the plant food.
Should a Christmas cactus be fed while blooming?
- Use Miracle-Gro Cactus, Palm & Citrus Potting Mix to grow your Christmas cactus.
- To enhance blooming, give your Christmas cactus 6 weeks of increased darkness and cooler temperatures.
- To make new Christmas cacti, root the stem parts you trimmed off the plant.
Should you fertilize cactus when blooming?
This aids the plant in replenishing nutrients taken from the soil throughout the growing season.
Cactus do require fertilizer. The right fertilizer, applied correctly and at the right time, aids the plant’s growth.
Fertilizing plants throughout active growth stages to promote healthy growth, vibrant color, and flowering in species that can blossom.
When should you fertilize a Christmas cactus?
Holiday cacti prefer mild shade and warm temperatures. While full sunshine is good in the fall and winter, intense sunlight in the summer can cause plants to become pale and yellow. During its growing season, which runs from April to September, temperatures between 70 and 80 °F are ideal for spring and summer growth. Thanksgiving and Christmas cactus rely on shorter day lengths (8 to 10) and cooler temperatures to establish their flower buds in the fall. Once the flower buds have been placed in the fall, keep the temperature below 90 degrees Fahrenheit. Warm temperatures can cause flower buds to fall off. If temps drop below 50 degrees Fahrenheit, don’t leave these cactus outside.
Temperature adjustment and photoperiod (day and night length) control are key to effective flower bud formation in the fall. Plants require the following to start flower buds:
- The nights are long. Flower bud set requires fourteen hours or more of continuous darkness each day. Long evenings should begin around the middle of September and last at least 6 weeks to ensure proper bud set. Flower bud set can be inhibited by as little as 2 hours of interrupted lighting. Buds will usually appear in 3 to 4 weeks. Once the buds are set, the photoperiod has little effect on flowering.
- For optimal bloom output, keep fall growth temperatures between 60 and 68 °F, preferably as close to 68 °F as possible. Plants planted in temperatures ranging from 50 to 59 degrees Fahrenheit will produce flower buds regardless of day length, however growth may be slower and bud drop may occur at 50 degrees Fahrenheit.
- Early in June, pinch back the stems to encourage branching and more terminals for more flowers.
- At the end of September, pinching (also known as leveling) is performed to remove any terminal phylloclades that are less than 1 cm (0.4 inch) long and to make all stems roughly the same length. Flower buds will not form on these immature and short stem segments until they mature. A flower bud grows on the previous, more mature stem segment after a short phylloclade is removed.
Watering and Fertilizer: When the growing media is dry to the touch, water it. During the spring and summer, the holiday cacti can tolerate dry, slightly under-watered conditions. Allowing the soil to grow saturated, especially during the dark days of winter, is not a good idea, but neither is allowing it to totally dry out. To prevent flower bud abscission, the growing media must be kept uniformly moist following bud set in the fall. Allow no water to collect in the saucer beneath the pot.
Fertilize plants monthly using a half-strength soluble fertilizer, such as a 20-10-20 or 20-20-20 with trace elements, starting when new growth begins in late winter or early spring and continuing through the summer. Holiday cacti have a greater magnesium demand than many other plants. Apply Epsom salts (magnesium sulfate) combined at 1 teaspoon per gallon of water once a month throughout the growing season, but not on the same week as the regular fertilizer. Fertilize less in the late summer to encourage more flower bud formation in the fall.
Growing Media: Holiday cacti flower best when they are kept in a pot. Repotting is only required every three years or so, and it is best done in the spring. Because these epiphytic cacti do not grow well in heavy, moist potting mixes, the potting medium must be well-drained with excellent aeration. 60-80 percent potting soil and 40-20 percent perlite make a good mix. Choose a pH-balanced potting soil from a reputable manufacturer.
How do I keep my Christmas cactus blooming?
Thanksgiving cactus, holiday cactus, and crab cactus are all names for the Christmas cactus (Schlumbergera truncata). The leaf-shaped stem segments with curled, sharp teeth or claws around the margins are known as crab claws. The leaf segments of the Easter cactus (Schlumbergera buckleyi) have rounded edges. They all originated in the gloomy, damp forests of southeast Brazil. They’re called epiphytes because they thrive on trees above ground, in places where branches meet and decomposing fallen leaves and mosses collect.
Despite the fact that this plant is called a cactus, the care it requires has little to do with its desert cousins. It’s a cactus that grows in the forest. Its requirements can be traced back to their source. The optimum time to plant a Christmas cactus is when it is warm “I’m stuck in a pot.” This entails keeping it in a small container for as long as possible before transferring it to a little larger pot. They prefer a nutrient-dense organic potting mix and should not be allowed to dry out. When the plant is blossoming, increase the amount of water it receives. They enjoy indirect light that is bright. As the plants begin to burn, the leaf segments might turn a dark crimson color.
‘The’ “The “secret” to getting your Christmas cactus to bloom in the years after you buy it boils down to two factors: light and temperature. These two are the keys to the kingdom of flowers. Flowers are produced by Christmas cacti in a chilly, short-day cycle. It takes at least eight days of 16 hours of darkness and 8 hours of light every day to start the creation of flower buds. Do not turn on the lights at night, even if only for a brief time, wherever the plant is put. This violates the required dark cycle. It should be around 61 degrees Fahrenheit. Avoid placing the plant in an area where it will be exposed to cold or hot air drafts.
It’s as simple as putting the Christmas cactus on the window sill in a chilly room and not turning on the lights. If the plant was in a brightly lit room, the side closest to the window often grows buds, but the plant’s illuminated side does not. If the plant produces flower buds but then loses them, it’s usually due to either too much or too little water or a lack of air humidity. The good news is that if their temperature and light needs are met, Christmas cacti are reasonably straightforward to re-bloom.
Why are the leaves on my Christmas cactus limp?
A lack of water or too much direct sunlight can create wilted or limp Christmas cactus. If you haven’t watered the wilting Christmas cactus, start by giving it a small sip. Continue to water gently every several days until the soil is wet but not saturated.
Christmas cactus troubles are sometimes caused by damp soil. Because the Christmas cactus is an epiphyte that takes water and nutrients from the air in its natural habitat on the tropical forest floor, it cannot tolerate damp roots. Christmas cactus can become very limp because to poor drainage and damp roots.
If the leaves on your wilted or limp Christmas cactus appear to be dried or burnt, move it to a more shady location, especially in the afternoon.
Why is my Christmas cactus blooming in June?
“What went wrong with my grandmother’s Christmas cactus that is about to bloom? Mary Ann
Hello, Martha. In addition, I have a “I have a “Christmas” cactus flowering right now, and I’m dubbing it my Winter cactus because of the blossoms. In Missouri, these hardy tropical plants require a little assistance to bloom on time. They have meteorological triggers in their native Brazil that cause them to blossom in December, the start of the South American summer.
If it originated from your grandma, your cactus could be an older, authentic Christmas cactus. The majority of cacti on the market now are Thanksgiving cacti, which explains why they bloom around late November.
Look at the green fronds to see what kind of cactus you have. Thanksgiving cacti (Schlumbergera truncata) have pointed, jagged edges, whereas the original Christmas cactus (Schlumbergera bridgesii) has smooth, round edges.
Because I had it outside on my back porch last fall, it began to bloom. Thanksgiving and Christmas cactus are known as “short day plants,” as they require fewer daylight hours and/or cool night temperatures to generate bloom buds. The shorter days and chilly nights of autumn prompt the plants to start producing buds.
Place your Christmas cactus indoors in a cool, bright setting with daily temps of 65-70° F and evening temperatures of 55-65° F to ensure that it blooms when you want it to. Plants will blossom in around 5-6 weeks if they are exposed to colder night temperatures of 55° F, independent of the day length.
Do cactus need to be fertilized?
Despite the fact that cactus can live (and thrive) in some of the world’s toughest environments, most prefer several tiny feedings over a single massive inundation. Cactus plants don’t require much in the way of water or fertilizer (they do require a lot of bright light).
Fertilizing cactus plants at least once a year is a decent rule of thumb, but if you’re extremely organized and can set up a routine, feeding them 2-3 times a year in the spring, summer, and fall will easily satisfy your cactus fertilizer needs.
Fertilizer is required more frequently by cactus plants during their active growing seasons than at any other time. To ensure that they do not miss their prime growing season, many gardeners utilize a time-release system that feeds the plant for a longer length of time, such as 3 or 6 months.
Finally, when caring for your cactus plants, remember one of the “golden principles of growing”: never overfeed! Overfeeding your cactus plants is just as bad as overwatering any other plant. Understanding when to feed cactus plants and how to fertilize a cactus is just as critical as knowing when not to overfeed. It increases the chances of your plants remaining healthy and happy.
Is Baby Bio OK for cacti?

Should I deadhead Christmas cactus?
Deadheading cactus flowers can promote additional blooms and encourage growth while also tidying up the cactus. While not necessary for all cacti because some cactus flowers drop from the plant once they are spent, deadheading cactus flowers can promote additional blooms and encourage growth while also tidying up the cactus. While the Christmas cactus is in bloom, deadheading can be done at any time during the growing season.
