How Do You Take Care Of An Opuntia Macrocentra?

What Is Opuntia Macrocentra?

Opuntia Macrocentra is an upright spreading plant that has an assortment of purple and green tints, red and yellow blooms, and deep red delicious fruit. It is distinguished by huge spine-covered pads, and its color varies with temperature, making it an intriguing addition to any garden.

Opuntia Macrocentra is a slow-growing perennial cactus that may reach 30 – 120 centimeters in height, 3 meters in breadth, and 10-20 cm in length. Each plant has roughly ten pads and no identifiable trunk. It is a kind of cactus native to the Southwest United States and Northwestern Mexico, although it may be found at many different elevations below 5000 feet, including deserts, steep hills, and valleys.

Opuntia macrocentra requires up to 6 hours in full or partial sunlight every day. Keep Purple Prickly Pear away from the afternoon sun if planted in an outdoor garden, since its powerful rays will burn the leaves. Place Long-spine Prickly Pear near a window that receives regular sunshine as an indoor plant.

If you reside in the Northern Hemisphere, for example, a room with a southern-facing window would be excellent.

If providing regular sunlight is problematic, installing macrocentra beneath a Grow Light is another approach. Sunlight is essential for developing a healthy succulent. Etiolating can occur in the absence of regular sunshine.

This is a situation in which the plant’s leaves extend out as though yearning for sunlight. The leaves will lose their exquisite form, be thin, and perish.

Giving the soil water while it is still damp can endanger the health of your succulent since the roots may rot. Similarly, the soil might become a breeding habitat for bacteria and fungus.

Watering succulent plants is not a difficult task. Simply wet the soil once it has become scorched. This is referred to as the “Soak and Dry” procedure. You may simply test the soil’s dryness by inserting your finger or a stick an inch deep. It’s fine to water the soil or the stick if it feels dry. Watering from above will cause the plant to become moist. Water only the soil.

Irrigate the soil every seven to ten days during the spring and summer growing seasons. In contrast, because the soil retains moisture longer in the winter, you may just water it once a month.

How Do You Take Care Of An Opuntia Macrocentra?

Opuntia Macrocentra is easy to care for. Additionally, it is a long-living plant. Provide a minimum of four to six hours of sunlight per day, but avoid exposure to full sun for extended periods since the leaves will burn and eventually die.

You should water your Opuntia macrocentra every three to four weeks in a dry climate, and once every week in a humid climate. You should not let the soil dry out completely or turn it into a swamp. Watering may sometimes become a problem if the potting soil gets too heavy or stinking bacteria and mold.

It requires strong air circulation to prevent this. If the soil is too heavy, try periodically stirring it with a chopstick or similar long object. Prickly pear can endure very severe droughts without any adverse effects. Here are some tips on how to take care of your Opuntia macrocentra.


Opuntia macrocentra is a thorny cactus that can withstand heat and little to no water. The cactus stores water in its pads and stems to survive sustained drought. However, if you are growing the plant indoors, its potting medium should be watered about once every two to three weeks for the best results. When you do water, make sure to thoroughly soak the soil and then allow it to dry out completely before watering again.


Opuntia macrocentra prefers full-sun exposure. However, it can survive in partial shade. It requires up to 6 hours in full or partial sunlight every day. If grown in an outdoor garden, keep Purple Prickly Pear away from the afternoon sun, since its intense rays will burn the foliage.

As an indoor plant, place Long-spine Prickly Pear near a window that gets plenty of sunlight. If you live in the Northern Hemisphere, a room with a southern-facing window would be ideal.


Opuntia macrocentra needs a well-drained potting mix. The soil needs to drain well so that the plant does not become waterlogged. Refer to the Owner’s Manual for your plant for specific recommendations on its potting medium, since these may vary from one variety to another.

If the top layer of your soil feels damp and smells unpleasant, then it probably needs more air circulation. Try stirring the soil with a chopstick or similar long object. This might help reduce the problem until you have time to replace it with better quality potting mix.


Opuntia macrocentra does not need any special fertilizers for best results. If you want to fertilize this plant, use a balanced fertilizer. It does not require any fertilizer at all if you are growing it indoors in a sunny spot. But if you keep your plant outdoors, then it will do better with regular fertilization in spring and summer.


Opuntia macrocentra needs to be protected from frost and temperatures below 45 degrees Fahrenheit. The cactus can withstand temperatures above 90 degrees. It is a frost-hardy cactus, hardy to -7° C (-12° C or less if very dry).

In cultivation, however, it is best not to expose it to temperatures below -0° C, even if in an aerated and sheltered environment, to avoid the production of anti-aesthetic patches on the skin.


Opuntia macrocentra prefers dry conditions and low humidity. If you are growing the plant indoors, it is best to let the air get dry between watering, especially in winter. If this plant is grown in a terrarium or a large vessel, then it requires high humidity.

The terra-cotta pot will only collect water and make the habitat too wet for your cactus. Even if the inside air is humid, microclimates can be created by exposing the plants to moist soil.


Opuntia macrocentra can be propagated from cuttings or seeds and offsets. It is best to propagate the plant from cuttings because it puts less stress on the plants since leaf loss is less likely. If you intend to grow two short-stemmed plants, cut several stems and make them into 4″ lengths. Make sure that each cutting has 3 to 5 buds. If you are only interested in propagating an individual plant, then you can use seeds.

Potting and Repotting:

Opuntia macrocentra can grow to be quite large, so you may need to repot every three to four years during the spring. Be sure to use a well-draining potting mix and a pot that’s only slightly larger than the root ball. When repotting, be careful not to damage the plant’s roots.

You can gently push the soil away from the roots and then fill the hole about halfway. The plant should be watered thoroughly and then left to drain for one or two weeks before repotting.


Opuntia macrocentra has a variety of pads and stems. After the plant has grown a bit, you may notice the pads beginning to turn brown. Take care to prune off any browning parts and dead stems. The cactus can tolerate having its top cut off at any point during the year. Growers of Opuntia macrocentra will often prune back young pads for easier access to the central pad or stem that contains the flowers.

Pests and Diseases:

Opuntia macrocentra is resistant to most pests and diseases. Scale, mealybugs, spider mites, aphids, and caterpillars are the biggest threats. However, insecticidal soap or horticultural oil can easily control these pests. For severe cases, use an insecticide containing Malathion or Dursban.

However, it is susceptible to powdery mildew, so it is important to regularly mist the plant with water if you grow it indoors, to help reduce the chances of this problem.

Is Opuntia Macrocentra An Indoor Or Outdoor Plant?

Opuntia Macrocentra is a succulent plant that can be grown both indoors and outdoors. If you live in an area with a lot of sun, then this plant will do best outdoors. If you live in an area with less sun, then you can grow this plant indoors.

The best way to water this plant is to let the soil dry out completely between watering. Water the plant once a week and make sure that the water drains out of the pot. Fertilize the plant once a month with a succulent fertilizer.

This plant does not need a lot of attention and can be left to grow on its own. However, if you want to keep it looking its best, then you can prune it back in the spring. The plant grows to be about 1-2 feet tall and has oval-shaped pads. The pads are covered in small spines, which are modified leaves. The flowers of the plant are yellow and grow in clusters. The plant blooms in the spring and summer.

The plant is drought tolerant and can tolerate some shade, but it prefers to be in full sun. It is not cold-hardy and will not tolerate frost. Opuntia macrocentra is a good plant for beginners because it is easy to care for.

Opuntia macrocentra is a popular plant for use in landscaping, as it is low-maintenance and drought-tolerant. The plant can be grown in full sun or partial shade, and it prefers well-drained soil. Opuntia macrocentra is not frost-hardy and should be protected from cold weather. The plant can be propagated from stem cuttings or seeds.

Opuntia macrocentra is a succulent, so it stores water in its leaves and stems. The plant does not need to be watered frequently, and over-watering can cause the plant to rot. The plant should be allowed to dry out completely between watering.

Opuntia macrocentra is not a fast-growing plant, and it may take several years for the plant to reach its full size.
