The stems look greenish when young and greenish-yellow when they get older and covered on the entire surface by white, long & soft hair like spines cascading downward which resembles the appearance of Monkey’s tail. They are branched to three to five stems at the bottom. The stems start drooping and become pendant after reaching a certain height. Each stem can increase in size by nearly a foot every year and reach to 3 or 4 feet length. These long protruding stems on the hanging basket makes the garden look really attractive. Their soft harmless appearance lures people to touch them but it is to be noted that the flesh of this cactus is non-edible.

2. Flowers

The flowers of Monkey Tail Cactus produce bright red flowers that make the plant look particularly fascinating and eye-catching. After a few days, the flowers  turn into fruits and disappear shortly. They are popular for blooming throughout the year with summer and winter being the main season. The contrasting features of these flowers bring peace to our soul. During winter and autumn, they undergo dormancy for some rest. This dormant period prepares the plant to bloom and grows beautiful red buds. The growth rate increases considerably during summer and spring.

Care of Monkey Tail Cactus

This cactus can thrive well in little care and doesn’t need special techniques to grow which make it popular among the people interested in house plants with busy schedules. Some caring tips for monkey tail cactus are discussed below:


They do well in areas that receive plenty of bright, indirect sunlight. Indirect light is ideal, but this desert-native cactus can tolerate direct sunlight too. They must be kept in the area with bright indirect sunlight if grown indoors. This succulent thrives best outdoors in bright indirect sun and is used widely outdoors as a hanging basket. Their blooming frequency depends on the amount of sunlight they receive. They may not bloom as often as they do outdoors if kept indoors.


They are popular due to their capacity to withstand a wide range of temperatures. They can even withstand the temperature below freezing point as low as -6°C(20 °F) during dormancy to above 15 °C(60 °F).    


A well-draining organic soil mix or the sandy and loamy soils with the characteristics features  like proper aeration, lightweight and quick drainage are considered ideal for this cactus. The stem suffers from water rot and many fungal infections in case of poor drainage, water stagnant and water lodging conditions. Salty soil can damage this plant. So, if Cocopeat is being used in potting mixture, they must be pre-washed in order to leach out its salt content. Perlite can be added on the soil mix to increase drainage.


Frequent watering is required only during the fast and vigorous growing phase when water drains quickly exclusively during summer and spring. The intensity of watering depends on the dryness of the ground and air temperature. The frequency is directly proportional to the warmth present  in air. The watering process is completely paused during their dormancy period. Watering it during dormancy, mostly during the winter  period may result in frosting and can lead the plant to death. Not a  single drop of water is given to the plant cuttings after propagation and light misting can be done only after 15 days of planting.


Low nitrogen fertilizer is incorporated into the potting mixture during its active growing phase. It can be best applied by diluting the fertilizer solution with the water and spreading it as liquid fertilizer which can complete the whole year requirement at once. Since it doesn’t require any special care, application of nitrogen is enough to fulfil its nutrient requirement.

Potting and Repotting for Monkey Tail Cactus

Due to their shallow roots, they can thrive in small pots but it should be replaced by a hanging basket while repotting to allow the flowing stems to trail. The potting mixture can be prepared using one part coco peat, half part sand, half part vermicompost and teaspoon fungicide powder mix. The pot should be selected in such a way that the water can drain out quickly. The cutting is then planted maintaining polarity and the pot is kept at the place with indirect sunlight. The potting mixture is changed to normal organic soil mix after the appearance of small roots on cuttings.

Due to its rapid stem growth, they are mostly repotted every year preferably after the completion of vigorous growing season. The long stems are trimmed or the pulps are separated and the plant is then transferred to another bigger pot with a friable potting mixture containing fertilizers and nutrients sufficient for the large plant to flourish.

Propagation Of  Monkey Tail Cactus 

They can be propagated through seeds as well as the stem cuttings and pups. We can follow one of the best way to propagate the Monkey Tail Cactus.

By Seeds

By Cuttings

Cutting is considered easy and convenient during summer and spring seasons where the  rapid and vigorous growth occurs. While cutting of Monkey Tail Cactus are made remember that sharp cut should be done at any part of a healthy long stem about 3-4 inch from top and let them dry and get calluses from bottom for a few days.

The fungicide powder or paste is applied on the cut portion of the plant to prevent them from rain rot or any fungal diseases. Watering is totally forbidden for the first 15 days. When tiny white roots are visible, the plant is now transferred to sandy and well aerated soil for further growth. Since they are hanging cacti, two or more cacti are planted in the rim of the pot making the hanging basket attractive.

By Pups

Pups can also be used for propagation of new plants. In the case of other cactus pups we can easily remove them from the mother plant when we turn them around but this cactus will break or damage if the cutter or blade is not used.
