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.
How should an orchid cactus be watered?
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 are cactus orchids cared for?
Bright but not in the way of direct sunlight. Light deficiency results in spindly growth and few flowers.
Water: While the plant is growing, keep the soil moist from spring through fall. Water sparingly in the winter until the onset of new growth in the spring. Never let it get too dry. Too-dry soil is indicated by shriveled, limp stems. Cut off any damaged stems since overwatering causes stem rot.
Indoor humidity: moderate (about 40-50 percent relative humidity). If required, place the pot on a tray of moist pebbles to increase humidity. A cool-mist room humidifier is the greatest technique to increase humidity in a very dry home.
Average room temperatures range from 65 to 75 F (18 to 24 C). The plant needs 8–10 weeks of cold 60–65°F (16–18°C) days and 45–55°F (7–13°C) nights in winter to set flower buds.
For faster drainage, use 1 part perlite and 1 part peat-based potting mix in the soil.
From early spring through the fall, fertilize every two weeks using a high-phosphorus water-soluble fertilizer. Feeding should cease in the winter.
For propagation, cut stem portions into 4-6 in (10–15 cm) lengths in the spring. After letting the cut callous for a few days, plant the cut end upright in a lightly moistened potting soil. Cuts should be kept at ambient temperature (65–75°F/18–24°C). Stem cuttings quickly take root in 4-6 weeks.
What is killing my orchid cactus?
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.

How much light is required by an orchid cactus?
Filtered sunlight is ideal for cacti. They appear to enjoy a few hours of direct morning sunlight, but never direct midday sunlight. Place your plants in a cold (above 40 degrees F) environment if you wish to overwinter them inside. After daylight savings time, avoid turning on the lights. Flowering for the following year could be hampered or even prevented if lights are turned on after sunset.
Check your cactus for excessive or insufficient light exposure. Your plant is receiving too much light if its growth is sunburned or has a yellowish tinge. Weak, leggy growth indicates insufficient light for your plant. The plant is receiving the proper amount of light when it has new growth that ranges in color from light to dark green with slightly reddish borders.
How much time do orchid cacti 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.
Should you water cacti when they are in bloom?
Watering: Mist your plant frequently when it is in bloom to keep the soil equally moist. Light: For moderate light and some direct sunlight, place the cactus in an east-facing window. Once buds start to grow, fertilize every two weeks with a high-potassium fertilizer.
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.
Are all orchid cacti night-bloomers?
The flowering succulent genus Epiphyllum and the cactus family Cactaceae both contain orchid cactus plants. A distinctive feature of orchid cacti is their broad, leaf-like stalks with scalloped borders. Many Epiphyllum cacti are distinguished by their beautiful, large white flowers in the shape of bowls. Hybrids of the orchid and cactus generate stunning blossoms in vibrant pastel hues.
Tropical woodlands in Central and South America are home to orchid cacti. The orchid-like cactus thrives as an epiphytic plant in dappled sunlight in its natural habitat of forests. Similar to how orchids grow, the orchid cactus affixes to a host plant and takes in nutrients from there.
Dutchman’s pipe, lady of the night, and climbing cacti are some of the other names for the Epiphyllum cactus.
Disocactus orchid cactus hybrids bloom during the day, but Epiphyllum cacti typically bloom at night. Numerous hybrids of the orchid and cactus also produce magnificent funnel- or cup-shaped blooms in shades of pink, yellow, orange, and creamy-white.
Are Christmas and orchid cacti the same thing?
Plants that only bloom once a year in short but beautiful displays are frequently kept around by gardeners. This entails taking care of the plants throughout the year and watching for the stunning first blooms to open.
Some plants blossom at the end of the long winters and provide a springtime tonic.
The orchid cactus, which is closely linked to the more popular Christmas cactus, is one illustration. A few of the flat-leaved, lobed stems from a parent plant are broken off and placed into a pot of soilless mix to reproduce the plant.
Even if I occasionally plant into pure soilless mix and add the sand to the soil surface, I always add a little bit of sand to the cactus mix because all cacti thrive in light, well-drained soil. The sand eventually becomes a soil improvement by sinking into the ground.
The slips take root quickly, and soon the quickly expanding stems will spill over the pot’s edge. These stems will blossom after a year.
The branches begin their growth upright but become pendulous as they grow longer. Along the primary stems, lateral branches grow as the stems become longer. A good specimen plant can be created by planting about six slips in a six-inch pot.
Like the Christmas cactus, an orchid cactus enjoys bright light but does not like a lot of direct sun or scorching, midday sun.
The soil should be maintained somewhat dry throughout the winter, but it should never be allowed to entirely dry out since this could prevent the plants from blossoming.
Orchid cactus need to be slightly root-bound before they bloom because most cacti want to be pot-bound.
If the plant is fertilized a few times in the early spring and again after it blooms, the lovely, mid-green leaves will keep their healthy appearance.
The orchid cactus enjoys low winter temperatures like the Christmas cactus, which promotes the formation of buds. Due to its photosensitivity, it needs complete nighttime darkness in order to set buds.
The earliest flowers, which are brilliant red and funnel-shaped, appear around the beginning of May. Each bloom lasts for a few days, and buds develop over the course of three to four weeks.
The orchid cactus can be relocated outdoors for the summer in a spot that receives filtered sunlight, just like its cousin, the Christmas cactus, but the plant needs to be brought back inside before the risk of fall frost.
