To begin, check to see if the ground is dry. Grab the plant’s base and remove the old soil before shimmying it out of the pot. Put it in a little bigger pot and add some well-draining potting soil to the rear. Wait until your prickly pear’s roots have fully reintegrated before watering it.
When ought my prickly pear cactus to be repotted?
Opuntia species, including prickly pears, are relatively common desert cactus planted as indoor houseplants. They have wide, flat, thick, spine-covered pads on segmented stems that are exceedingly decorative.
Others contain small, hair-like barbs that detach upon contact with the plant, stick in the flesh, and can be challenging to remove, so treat with caution. Some have huge, rounded spines.
The edible, lemon- or plum-shaped prickly pear fruit of several Opuntia species, commonly referred to as “Indian figs,” is becoming into a delicacy in the UK. They are attractive and colorful as well. When fully grown, the meat inside turns orange and the outside turns bright red. When ripe, some types have a yellow outside and a green interior. These are utilized in syrups, preserves, and jellies because they aren’t quite as sweet. However, for plants to grow healthy fruit in the UK, the environment must be ideal.
Cultivation
Prickly pears should be cultivated inside in a conservatory or heated greenhouse with good, all-around lighting, ideally with a south or west facing aspect. In the summer, they require 4-6 hours of direct sunlight.
Although they are not cold- or frost-resistant, they can be brought outside in the summer to a warm, sunny patio. Make sure to bring them inside before the early autumn weather turns chilly.
They require minimum spring and summer temperatures of 18C (65F), however while they are dormant, they prefer colder temperatures of 7-13C (45-55F). Keep them away from radiators, direct heat, draughts, and fans, which can lead to temperature changes.
Prickly pear cactus varieties
Opuntia has more than 200 different species. From low-growing plants that grow to a height of 30 cm (1 foot) to those that can easily reach 5.4 m (18ft).
Opuntia microdasys, sometimes known as bunny ears, is likely the best kind to cultivate at home. Only reaching heights of 30-45cm (12-18in), it has oval pads covered in tufts of tiny, golden spines. But don’t let their diminutive size deceive you; if they get caught in your fingers, these tiny barbs can be just as unpleasant as much larger spines.
Planting prickly pear cacti
They require a compost that is extremely well-drained, just like all other desert cacti, so either add more grit to John Innes Compost or, even better, use a compost that is recommended for cacti and succulents.
To give the compost a natural, finished appearance and to help prevent the plant’s base from lying in wet compost, add a topdressing of gravel, pebbles, or sharp sand on top of the compost.
When working with the plants, be mindful of the spines. It is preferable to wear gloves and wrap a collar made of rolled-up newspaper around the stem when potting up or otherwise moving the plants.
How to care for prickly pear cacti
Many people mistakenly believe that desert cacti don’t require any watering. They can withstand extended droughts by storing water in their stems, but if given enough water, they develop and blossom considerably more effectively. When plants are growing (from March/April to September), water them heavily, but when they are dormant, water them less frequently—once or twice a month may be adequate. Before watering it once more, let the compost somewhat dry out. Never let the pot sit in water; always let the compost drain.
Feed with a balanced liquid feed once a month from late spring to late summer while plants are growing; do not feed in the fall and winter.
Only when it is absolutely necessary, such as when they become very potbound or outgrow their current container, can prickly pears be replanted. Repotting should only be done in late spring or early summer into a larger pot.
How is a prickly pear cactus transplanted?
For at least a year, cultivate the cactus in the pot. In the spring, after the soil reaches a temperature of 60 degrees Fahrenheit, transplant the cactus plant. Place the cactus in a location with ample sunlight and soil that drains properly. Create a hole that is twice as big and twice as deep as the root ball of the plant. Put the root ball in the hole’s middle. Soil should be piled back into the hole and compacted hard. After planting, immediately water the cactus.
Take a cutting
The first step in growing prickly pear cactus pads from a cutting is to carefully remove a pad from the main plant. Make an effort to separate as neatly as you can. Then let the cut end of your pad dry and harden slightly. While you are waiting for the cut end to heal, it may start to turn a little brown.
It ought should take a week or so. You don’t have to wait for the roots to sprout like you do with many other plants. The soil will experience this. (However, I believe mine had just started to sprout.) I left mine out on my dining room table for approximately two days because they had just been cut and had been in transit for about four days.
Why do the cut ends need to callus over?
In general, cacti don’t require a lot of water, and too much of it can quickly kill plants. A fresh cutting is comparable to a main line into the plant. If you take a cutting and plant it right away, it should survive without water for a few days. However, by allowing the cutting callus to form first, you increase your chances of success.
The callus serves as a barrier to stop the cutting from absorbing too much water. Other plants that are similar to it, such as succulents and snake plants, can be propagated using the same method. (See also my posts on how to grow succulents from leaves and cuttings and my explanation of how to grow snake plants in four different ways.)
Step 2: Plant the prickly pear cutting
Planting should be done once the cuttings have callused over. If you have access to rooting hormone, you can dip the cut ends of the pads into it before planting them, but it’s not necessary. The prickly pear is not one of the plants that I typically reserve rooting hormone for.
Simply place the cuttings upright in succulent or cactus soil that drains well, and water. Seek out my simple, three-ingredient succulent soil mix or simply get one from the supermarket marked “succulent” or “cactus.” Avoid use common, well-draining potting soils. For better drainage, ucculent/cactus soil contains more additions like sand and perlite.
When the top several inches of soil become dry, water the cuttings. Try to very gently tug on the cuttings after a few weeks. If you encounter opposition, kudos to you! Your cutting’s roots are starting to form. If a few weeks have passed and you are still not experiencing resistance, don’t worry. It may take some time, especially in the colder months of the year.
Step 3: Transplant or water as normal
My prickly pear pads didn’t require transplanting because I put them in the container I intended to keep them in. Wait until the roots are comparatively established before transplanting them if necessary. Make sure to cut back on watering once the roots are established and to wait until the soil has dried up before watering again.
An overwatered cactus will definitely die! Avoid over-watering the soil, as you did during the propagation phase. Since it is now a separate plant, root sprouting no longer requires additional assistance.
What kind of soil does a prickly pear cactus prefer?
Soil. Planting the prickly pear in well-draining soil is necessary for its success. The optimal mixture is one that is dry, sandy, or gravelly, but it can also thrive in a clay-based mixture as long as the soil drains effectively and does not retain a lot of moisture.
Can prickly pear cactus be grown in pots?
Pick a container with plenty of drainage holes at the bottom when growing prickly pears in containers. Given that these plants will sprawl as they grow, it is a good idea to select a low, broad pot to offer a nice balance. Fill it with a potting mix that drains well, such as one prepared especially for succulents and cacti.
Pruning:
Prickly pears don’t need to be pruned, but they can be trimmed back. To keep the pads’ size and shape, take out individual ones as necessary. Holding the pad in place with tongs, cut it off at the junction or line where it attaches to the following pad. Pads can be calloused off and shared with pals or planted somewhere else. Find out more about propagation below.
Amendments & Fertilizer:
Young plants should be fertilized with a balanced 10-10-10 fertilizer. A water-soluble fertilizer with a ratio of 5-10-10 or even 0-10-10 can encourage more flowers and fruit in established plants. Use a nitrogen-rich fertilizer if you’re growing for the pads.
Watering:
Prickly pears can withstand severe droughts. For the first month, don’t water newly propagated pads. After that, water during the first year every two to four weeks—twice a month in the summer and once a month throughout the other seasons. Rainfall will usually be sufficient to keep established plants alive. When there is a drought, you can supplement with the twice-monthly/once-monthly seasonal schedule.

Propagation:
Since seeds grow slowly at first, it can take your plant three to four years to begin blooming and bearing fruit. The seeds should be maintained moist until they begin to sprout since they require shade.
Pad propagation is considerably easier and produces results more quickly. This is how:
- By according to the above pruning rules, you can take off pads that are at least six months old.
- The cut end of the pads should create a callus if they are left to dry out in a spot with some light shade. This can take two to four weeks in warm, dry weather, but it may take longer under cool or humid conditions. It prevents the new plant from decomposing at the base.
- Plant pads at a depth of 1 inch in a mixture of half soil and half sand once they have fully calloused over. Your plant could rot if it were buried any deeper.
- For the first month, don’t water it because the pad already has enough moisture to survive.
- Until roots develop during the course of the following month, support it with rocks or another type of structure. Your plant should be able to stand on its own after a month, but if it’s still a little unsteady, keep providing support.
- You can water it at this time and follow the previous watering instructions, just make sure to let it totally dry between waterings.
Flowers and fruit normally start to appear on young plants by the second or third growing pad.
How long does a prickly pear cactus live?
The large, flat, green pads of the Opuntia engelmannii, also known as the Engelmann prickly pear cactus, are a sure sign of its presence.
The 3″ long white spines might be straight, curled, or flat. They are also covered in glochids, which are very tiny, barbed hairs. Each pad has several areoles, which are common central locations from which groups of up to six spines might arise. The golden flowers bloom between May and June. Beginning in July, ripe fruit can be discovered; they are recognized by their vivid red hue.
Prickly pears can be found growing in sandy or gravelly places, along rocky hillsides, around boulders, and in washes.
Prickly pears of the Englemann variety can be found throughout much of the arid southwest, from central Texas through southern California’s interior. Their distribution extends into central Mexico’s Sonora state as well as northern Baja California.
Prickly pear cacti come in a number of various types, each of which has a range of sizes. The Engelmann prickly pear, which may reach a height of 5 feet and a width of 10 to 15 feet, is the most widespread species in the Sonoran Desert.
- This cactus’ crimson fruit, which resembles a pear, is also called as “tuna.”
- Texas’ official state cactus is the prickly pear.
- At the foot of these plants, packrats frequently construct dens, which therefore offer refuge from some of its predators.
What depth do prickly pear roots reach?
Abstract:
Cacti have shallow roots, with the average depths for their diverse native Sonoran Desert species ranging from 7 to 11 cm and 15 cm for cultivated opuntioids; the cultivated vine cactus Hylocereus undatus has even shallower roots.
Although this shallowness makes it easier to absorb water after light rains, it also exposes the roots to high temperatures near the soil surface.
Extreme temperatures reduced the uptake of the essential stain neutral red into root cortical cells, with 50% inhibition (LT50) occurring for Nopalea cochenillifera, Opuntia ficus-indica, and O. robusta at an average of 7C for low temperatures and 57C for high temperatures, and for H. undatus growing at a moderate day/night air temperature of 25/20C, at 2C and 52C, respectively. The opuntioid LT50s showed seasonal adaptation to changing ambient temperatures, declining 1.2C as day/night air temps were lowered by 20C and rising 4.4C as they were raised by 20C.
In order to measure root growth, respiration, and layers with deadly temperatures, an equation is proposed to estimate soil temperature as a function of soil depth and time.
In this regard, the ability of most cacti to be cultivated today and in the future should not be constrained by the roots’ sensitivity to low temperatures.
Although fewer cacti roots may be found in the topmost soil levels as a result of rising air and soil temperatures brought on by global climate change, other (non-CAM) perennials should experience far larger restrictions.
Can a cactus be split in half and planted again?
A loved cactus plant might quickly lose a portion due to overly active kids, scavenging animals, an accidental bump, or an unplanned incident. If such a thing ever happens to you, no need to worry because you don’t have to throw away the chopped portion.
While the main plant can still thrive even after losing part of its stem, it may seem wasteful to throw away the detached section and forget everything.
Can you then cut a chunk off of a cactus and plant it? Yes is the clear-cut response. Cuttings can be used to grow a sizable number of cacti species. Some of the common cactus species frequently propagated via cuttings include a hedgehog, prickly pear, and branching columnar cacti such as the night-blooming cereus.
Don’t discard the broken piece if your cactus accidently breaks off a portion of it. Instead, replant it from seed and let it grow.
