In contrast to its relatives the typical cacti, orchid cacti require regular hydration during the growing season. Although damp, the potting mix shouldn’t be waterlogged. Prior to rewatering, you should ideally let the top third of the potting mix to dry out. Reduce watering over the winter and relocate the plant to a cooler area.
How often should an orchid cactus 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 planters 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.
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 characterise 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 favourable 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, fertilise the soil using a 10-10-10 balanced fertiliser 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.

How long do the flowers on orchid cacti last?
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 fertilising.
- 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 draughty 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.
What is killing my orchid cactus?
When caring for orchid cacti, the general rule is to let the top half of the soil dry up in between irrigations. It’s time for another sip whenever the pot starts to feel light and the compost’s top layer feels completely dry. Make careful to cut back on this even more in the fall and winter to mimic their dormant season and minimise the danger of overwatering. Avoid using cold water when plants are in flower throughout the summer because they are sensitive to cool root temperatures. There is little to no new growth, a critical transplant, and wilting leaves as signs of under-watering. On the other side, signs of overwatering include root rot, little to no growth, and yellowing leaves that quickly fall off. These are frequent in areas with excessive soil moisture, unsuitable soil conditions, or heavy shade. Take stem cuttings from unaffected growth by using the techniques described in “Propagation” if the foliage just above the soil line turns brown and mushy.
Can orchid cacti be grown indoors?
Care for orchid cacti. It is recommended to continue growing epiphyllums inside unless you can provide them with mild temperatures, dappled sunlight, humidity, and permeable potting soil. They prefer similar environmental factors to bromeliads and orchids.
How To Water Orchid Cactus Plants
The biggest danger to a healthy orchid cactus is overwatering. Keep your plant out of water at all times. However, you must take care to prevent their roots from drying out.
Water in the middle of spring through the summer when the top third of the soil feels just a little bit damp. The plant needs less moisture in the winter. During these hours of idleness, drink less water.
How, When and Why to Fertilize Orchid Cactus Plants
Apply a 10-10-10 fertiliser every two weeks throughout periods of growth, which last from spring through October. Use fertiliser with a nitrogen level of no more than 10%.
Apply a 2-10-10 fertiliser at the end of February and the end of October. Flowering will be promoted by this.
Take a break from fertilising throughout the winter because the plant cannot handle the excess nutrients during natural dormant periods.
How to Prune Orchid Cactus Plants
An orchid cactus should only be pruned to manage its size. If you want to prune, do so as soon as the plant finishes blooming.
Use spotless, razor-sharp shears to trim stems. This will lessen the risk of tearing. After pruning, take extra care not to overwater.
How to Propagate Orchid Cactus Plants
When pruning a plant, save the cuttings. This is the simplest method for growing an orchid cactus.
Simply cleanly chop off a stem to propagate. Give the end a week to “callus” (harden). Next, bury the developing end in a bed of tidy, moist soil.
There shouldn’t be more than two leaf serrations submerged in the dirt. Put the pot in a well-lit yet shaded area, and spray or water it frequently. The cutting won’t start to grow roots for three to six weeks.
When and How to Repot Orchid Cactus
Reporting orchid cacti varies, with opinions ranging from every two to seven years. If you do decide to repot, just switch to a larger container size. (Orchid cacti that are slightly root-bound tend to blossom more profusely.)
Repotting your cactus orchid should be postponed until around a month after flowering. Don’t dig up the root ball too deeply.
Simply shake it lightly to get rid of any extra soil before placing the root ball in the new container. Then add fresh soil and fill. After repotting, wait a week before watering.
You can add more soil if you have a big plant and don’t want to repot it. Top dress the plant in its existing pot just a little bit.
When ought my orchid cactus to be repotted?
Repotting plants should be done every seven years or so. Wait about a month after blossoming before repopping. Keep some of the dirt around the root ball in place. Simply brush off any extra soil with care before repotting in new soil. Repotted plants shouldn’t be watered for a week. Before going back to your regular watering regimen, water sparingly for one month.
