Growing orchid cactus is a delight because of its large, cup-shaped blooms in exquisite hues. Put it in a hanging basket to display it, letting the long stems spill over the container.
The stems of orchid cacti are large, flat, and have serrated edges. Their maximum size is 2 feet (60 cm) long and 2 inches (5 cm) wide. They don’t put on much of a show, but you can rely on them to bloom every spring.
Flowers can be 4-8 in (10-20 cm) broad and appear at the ends of the stems. Epiphyllum hybrids, the majority of which are grown now, can be pink, red, white, yellow, orange, purple, or bicolored. You’ll get several months of blooming if you give your tropical cactus lots of sunshine.
Pruning Orchid Cactus
Unless you wish to limit its size, you won’t need to prune. After it stops flowering is the best time to trim it back. To avoid ripping the stems, use clean, sharp pruning scissors.
Keep those cuttings from the orchid cactus! To get more of these fascinating plants, propagate them. (See below, “Propagation”).
Wondering Whether to Repot…or Not?
Every two to three years, repot and upgrade to a larger pot. A little pot-bound orchid cactus enjoys and blooms best in this environment. Never repot it while it is in bloom because this will make the buds and blooms fall off.
Instead, top-dressing large plants involves adding a layer of new potting soil. To prevent dirt from spilling out while watering, leave about an inch (2.5 cm) of gap between the soil and the container rim.
How to Make Orchid Cactus Bloom
It’s simple to grow this flowering cactus, however there are a few things you can do to encourage blooming:
- Give it a break this winter. For the plant to set buds in the winter, it has to have a cool, dry rest period of roughly 8–10 weeks. During this period, water lightly and cease fertilizing.
- Bring some clarity. All year long, keep your orchid cactus in direct light. Keep the plant away of direct sunlight if you transfer it outside for the summer.
- Feed it. Fertilizer with a high phosphorus content will promote more flowers. Feeding should begin in the early spring and continue into the fall.
- Just let it be. Keep the plant in the same spot after the buds start to develop. It will lose its buds and flowers if you move it because of variations in temperature and light. Maintain it away from drafty areas as well, such as entrances and HVAC vents.
One of the most well-known species in this genus is Epiphyllum oxypetalum, which is seen below. It produces fragrant, white flowers that bloom for just one night before dying by morning. You can capture it in full bloom if you approach it covertly at night.
Orchid Cactus Problems and Solutions
blown-off flower buds? Don’t move the plant after the buds have formed. Flower buds will most likely fall off as the light changes. But don’t worry, these tropical hybrids are hardy and, with proper care, will bloom exquisitely when given what they desire.
Is there a problem with your plant? Verify the plant for any potential mealybug and scale infestations. To stop pests from spreading to your other houseplants, treat any infestation quickly and isolate the damaged plant.
Stem rot, which is brought on by overwatering, manifests as limp stems that darken at the base. Any rotting stems can be removed at the soil line.
How come my orchid cactus isn’t blooming?
If they aren’t given the right fertilizer, some orchid cactuses won’t blossom. Most of the year, they benefit from monthly applications of balanced fertilizer, such as one with a 10-10-10 ratio of nitrogen, phosphorous, and potassium. Never use a fertilizer that has more than 10% nitrogen because too much nitrogen might cause lanky growth that stunts flowering. Stop fertilizing during the dormant season in December and January to prevent scorching the roots.
How do I get my cactus to bloom?
Cacti and succulents prefer summer and winter seasons, as well as a clear variation between night and day temperatures. Succulents prefer colder outdoor nighttime temperatures of 50-550F (10-130C) or at least 60-650F indoor nighttime temperatures (15-180C). Succulents prefer a noticeable contrast between their night and day temperatures to imitate their natural habitat, with the low night temperatures playing a crucial role in the plant’s growth cycle, especially when kept in a controlled setting.
If you want to see your succulents and cacti bloom, overwintering is also crucial. For desert cacti in particular, this can be accomplished by keeping plants cool and largely dry over the winter. During the winter, keep them at a comfortable temperature of between 35 and 440 °F (1.5-70C). If maintained indoors during the winter, try to keep them in an unheated room or keep the temperature low to provide them the necessary cold winter season. This does not apply to holiday cacti, such as Rhipsalis, Schlembergera, and Hatiora, which have different moisture and temperature needs than desert cacti (see below for Holiday cactus blooming tips).
Make sure the plants are kept in a bright area and receive enough sunshine throughout the year, including during the darker winter months. Most succulents and cacti require at least 4-6 hours of bright sunshine every day, if not more. Some plants require filtered but bright light to avoid solar damage since they cannot withstand harsh, full sun. Lack of light causes plants to gradually etiolate, become paler, and spread out in search of more light. To provide adequate lighting, place indoor plants in windows with a south or east orientation. If more light is required indoors, think about using grow lights. Lack of sunshine stunts the growth of succulent plants, and they are unlikely to blossom as effectively.
Giving your plants the nutrition they require instead of fertilizing them will assist maintain healthy growth and promote blooms. Flowers require a lot of energy to grow, therefore giving plants more nutrients during flowering season will assist meet their nutritional requirements. The best time to fertilize is during the active growing season, which is in the spring and summer. Fertilizers work best when applied every two weeks at a quarter- or half-strength. Avoid fertilizing during the winter and towards the conclusion of the fall growing season. It is acceptable and typical to use a balanced fertilizer blend that has been diluted to half strength. Cacti and succulent-specific fertilizer mixtures are also appropriate.
Although cacti and succulents can store water, they still require frequent watering during the active growing season. Regular watering helps to guarantee that they don’t lose all the water they need to store for growth. Regular watering also improves their ability to resist the hotter summer sun. Water plants thoroughly during the active growing season until water begins to leak out of the pot’s openings. Don’t water again until the soil has dried out. Before watering, check the top inch of the soil for moisture. During the hot summer months, watering should be done more frequently; during the chilly winter months, less frequently. Succulents and cacti suffer from overwatering, so make sure to let the soil dry out in between waterings.
Succulents and cacti require a well-draining soil in addition to suitable watering methods. Cacti and succulents don’t like to sit in water. If left moist for too long, their roots are prone to rot. The capacity of a succulent potting mix to drain efficiently is its most crucial requirement. You have the option of using store-bought potting soil or making your own for succulents. Giving them the proper medium increases their chances of flourishing and blossoming. Keeping your plants content will boost blooming.
How frequently do orchid cacti need to be watered?
The orchid cactus is a robust indoor plant that is not for the timid! Although it’s simple to cultivate, your friends will think you’re an expert houseplant grower because to its exotic appearance. The orchid cactus has unusual-looking long, flat leaves that grow to twist and curl. It’s a great option for hanging baskets and tall pots because the leaves trail.
If you cultivate orchid cactus, grow it in a smooth, modern ceramic container to highlight the texture of the foliage. Alternately, cultivate an orchid cactus in a pot with a rough edge to contrast the foliage.

Orchid Cactus Growing Instructions
In strong light, cultivate orchid cacti. This tropical houseplant is ideal for window-side hanging baskets (or you can take it outdoors to a shaded place for a little summer vacation). The plant may produce stunning, creamy-white orchid-like blossoms if it receives adequate light (hence its common name).
When the potted soil dries out, water the orchid cactus. This indoor plant, which is native to tropical rainforests and grows on trees, doesn’t like its soil to stay wet all the time and will rot if it is overwatered. Typically, depending on factors like plant size, temperature, and how much light your orchid cactus receives, that means watering it once every 10 days or less.
The orchid cactus demands high humidity, just like orchids and other tropical plants do, yet it typically thrives in typical home environments.
Add these varieties to your orchid cactus to complete the look:
Canine Cactus Another low-maintenance cactus that trails from hanging baskets is the dog tail cactus. With the orchid cactus, it looks gorgeous.
What is the duration of an orchid cactus’ bloom?
Benefits: The orchid cactus is a low-maintenance houseplant that blooms spectacularly for several weeks in the spring. It accepts dry air and watering delays.
Blooms: From slits in the leaves, showy, enormous flowers emerge in the spring and into the summer. There are numerous varieties with names that provide the whole spectrum of hues.
Its leaves are long, flattened, narrow, and have scalloped edges. The spines of orchid cactus are not particularly visible.
Habit: Orchid cactus develops as a clump of 20-inch-long, flattened leaves that droop and dangle. A hanging basket is the perfect vessel for their behavior. They can also be potted in a common container and set on a shelf that is high.
Origins: They reside in the treetops of tropical rain forests in Central and South America. They merely physically cling to their host tree.
How to cultivate an orchid cactus: These tree-dwelling epiphytic cacti appear best grown in a hanging basket, from which their prodigious flowers can hang at or just above eye level and their long, flattened branches can hang down. Given that these plants naturally grow on tree branches rather than in soil, choose a light, porous potting mixture with great drainage. Between waterings, let the soil totally dry out; when you do water, give it a good soak.
Provide 8 to 12 weeks of cool winter weather (40 F to 60 F at night, just slightly warmer during the day) to promote flowering, and don’t water during this time. Once the flower buds form, start watering again and move the plant to a warmer area.
How can I promote Epiphyllum blooming?
Epiphyllum typically need to be root bound before they bloom. This implies that before they will start to bloom, their roots must completely fill the container. Plants cultivated in 4 inch pots will flower more quickly than those grown in 8 inch pots.
How can I fix my orchid cactus?
Overwatering is the main problem that orchid cacti face. You can observe stems becoming limp or turning black at the base if your plant is submerged in water. Stem rot is the problem that causes this. If you notice stem rot, stop watering the plants. Trim off charred stems at the soil line.
Stems that turn yellow or appear withered may result from excessive exposure to bright, direct light. Another effect of too much light could be a tanned appearance.
On the other hand, if your orchid cactus requires more light, it might start to look lanky and frail.
Fungus gnats may become an issue if you overwater your plant. Aphids, mealybugs, and glasshouse red spider mites are among more potential pests. Use pesticide soap or neem oil to get rid of infestations.
Watch out for any spots on the stems as this could point to a fungus problem. When water remains on stems for too long, fungus frequently grows. By utilizing well-draining soil and keeping water away from stems, you can avoid fungus.
Are coffee grounds beneficial for cacti?
The decomposition of the used coffee grounds will enrich the soil with nitrogen, a crucial component for succulents. Along with improving drainage and aerating the soil, they may also reduce weeds and deter pests.
How can I tell whether my cactus is content?
Cacti enthusiasts are already aware that these desert plants can withstand the most extreme weather conditions. This does not imply that they are safe from illness, pest, or animal attacks. Cactus may tolerate some neglect, but it requires adequate care to be strong and flourish. A healthy cactus indicates strong chances and promise for future reproduction.
So how do I determine the health of my cactus? The physical characteristics of a cactus will show whether it is healthy. A healthy cactus has a robust, succulent stem, upright leaves, an equally green appearance, and strong roots, to name a few. A healthy cactus will be able to store a sizable amount of water without showing any indications of deterioration and will consistently produce brightly colored flowers during each flowering season.
The traits that distinguish a healthy cactus will be examined in this article. It will go over how to maintain the plant’s health and how to recognize any symptoms of ill health.
My orchid cactus can I place outside?
A. The orchid cactus is a lovely floral plant that deviates from the stereotype of cacti. The Epiphyllum orchid cactus inhabits rain forests rather than deserts. This cactus is indigenous to Brazil, where it can be found growing in the sides and forks of trees above rain forest habitats. It produces lovely flowers that usually bloom for a few days and open in the evening. It is pretty easy to grow an Epiphyllum cactus outside of its natural habitat, but you must pay close care to the temperature, lighting, and humidity.
Epiphyllum prefer bright, filtered sun exposure. Full exposure to the sun is great in the morning, but it becomes too powerful by noon. They will get sunburned if exposed to the sun in full for an extended period of time. Plants with sunburn show withered or yellow new growth. If you move your plant inside over the winter, make sure it is in a window that is covered or gets enough light to avoid a decline in health. If your plant spends the summer outdoors and you bring it within to overwinter, make sure you put it in a room with natural light that is chilly (40 degrees F or more). It can postpone blossoming the following summer if lights are turned on after sunset. These plants require this period of rest throughout the colder months. Keep an eye out for excess or underexposure to light in your cactus. It usually indicates too much light when your plant’s growth becomes yellowish and withered. Lack of light causes weak, lanky plants. Light to dark green with slightly reddened borders should characterize new growth. This demonstrates that the plant is receiving sufficient light.
For the Epiphyllum orchid cactus to successfully flower, it needs enough water. Unfortunately, according to the Oregon State University Extension, overwatering your cactus is the worst thing you can do. Root rot may result from waterlogged soil, which also attracts water-loving fungus that require standing water to germinate. Water once a week, but wait until the top 2 to 3 inches of the soil are totally dry before re-watering. If the soil takes longer to dry, adjust your watering plan. Roots should be wet but not saturated.
Despite being able to withstand high temperatures in wet, shaded environments, epiphyllum plants thrive in temperatures between 45 to 70 degrees Fahrenheit, according to Clemson University Extension. For orchid cacti that have already started to bloom, overnight winter culture must maintain a temperature range of 40 to 50 degrees F. Due to our climate’s favorable outdoor conditions in the summer and early fall, this plant thrives.
Humid circumstances are crucial to both human civilization and rain forest culture. This flowering cactus grows best in environments with at least 50% humidity. In the winter, our dwellings are frequently rather dry. If the humidity falls too low, think about misting your plants with water. Extremely dry circumstances can cause root issues, especially if the soil is poorly drained. Furthermore, bud drop frequently happens when humidity levels are insufficient.
For Ephiphyllum plants, an optimum soil environment is one that drains well and is high in organic matter. The winning soil recipe, according to the Clemson University Extension, includes one part sand, one part garden soil, and two parts peat moss. According to the Oregon State University Extension, fertilize the soil using a 10-10-10 balanced fertilizer and stay away from those that have a nitrogen level greater than 10%.
Plant pests barely affect these plants at all. If the soil is kept excessively wet, fungus gnats could become an issue. Slugs and snails can cause significant harm to these plants if they are able to get to them when you are growing them outdoors in the summer.
Epiphyllum typically need to be root bound before they bloom. This implies that before they will start to bloom, their roots must completely fill the container. Plants cultivated in 4-inch pots will flower more quickly than those grown in 8-inch pots. While hybrid epiphillums bloom during the day, true epiphillums bloom at night. White and yellow flowers begin to bloom in late April. Pink and red flowers begin to bloom in May. (deep reds and purples). Repotting should be done on average every seven years. Wait about a month after blooming before repotting. Keep some of the dirt around the root ball in place. Simply brush off any extra soil with care before repotting in new soil. Re-potted plants shouldn’t be watered for a week. After that, water sparingly for a month before going back to your regular schedule.
Plant cuttings are available for purchase or for taking. If you decide to start with cuttings, give them about a week to harden off before planting. Plant cuttings in a potting soil combination that is clean and dry. Three parts commercial potting soil and one part small to medium pumice provide the ideal potting mixture for cuttings. Use bark chips or perlite in the absence of pumice. The soil needs to retain moisture while draining swiftly. For optimal results, plant cutting upside down. Place the little growing end in the ground 1 to 2 inches deep. There should be two leaf serrations that are below the soil line. Put the pot in a well-lit, shaded area. Cuttings that have been rooted shouldn’t be left to dry out. At first, water sparingly; after that, water once per week.
