- White-haired prickly pear (Opuntia leucotricha)
- Beneficial features
plant (lat. Opuntia) belongs to the largest genus of the Cactus family, numbering about 190 species. In nature, prickly pears are common in North and South America, including the West Indies. Mexico is considered the main growing area for prickly pear, where about half of its species are concentrated. Aztec legend tells that Tenochtitlan, the main city of the Aztecs, was founded on the spot where an eagle sitting on a prickly pear ate a snake - this scene is depicted on the coat of arms of Mexico. The Indians used the fruits and shoots of some types of prickly pear for food, and also grew this cactus to produce the dye carmine. But among prickly pears there are neophytes that are so aggressive that it is necessary to use biological means of destruction against them. In indoor culture, prickly pear has taken root all over the world, right up to Australia.
Planting and caring for prickly pear
- Flowering: almost never blooms at home.
- Lighting: bright sunlight in the morning and diffused light in the afternoon.
- Temperature: in the warm season - normal for residential premises, in winter - no higher than 5-7 ˚C.
- Watering: in spring and summer - moderate, as for all succulents; in winter, if the cactus is at rest, do not water. To moisten the substrate, the method of bottom watering is used.
- Air humidity: does not matter.
- Feeding: once a month from March to September with complex mineral fertilizer with low nitrogen content. From October to March, fertilizing is not carried out.
- Dormant period: in the fall, watering is reduced, fertilizing is stopped, the cactus is placed at a temperature of 5-7 ˚C until spring.
- Transplantation: young plants are replanted annually, adults - no more than once every 3-4 years in the spring, before the start of active growth.
- Reproduction: by segments, rarely by seeds.
- Pests: spider mites, mealybugs, root nematodes, scale insects and whiteflies.
- Diseases: pythium root rot, late blight, gray rot and wet stinking rot.

Botanical description
The prickly pear flower is a perennial evergreen cactus, which is an erect or creeping shrub or tree with succulent, jointed, flat stems with large or small spines and tufts of thin and fragile hook-shaped bristles called glochidia. The leaves of prickly pear are small, subulate and succulent. Prickly pear blooms with bisexual single flowers of yellow, orange or bright red. The fruits of the prickly pear cactus are edible berries with flat seeds in a hard shell.
Caring for prickly pear at home
Growing conditions
The prickly pear cactus is light-loving, and it requires bright light all year round. However, prickly pear should be accustomed to direct sunlight gradually. Prickly pear feels good at home almost all year round, but in winter it is better to move it to a place where the temperature does not rise above 5-7 ºC, since wintering in a warm place causes the plant to stretch out strongly and painfully. Caring for prickly pear at home comes down to watering, fertilizing and replanting the plant.
Watering
In spring and summer, indoor prickly pear needs moderate watering, like all succulents, but in winter, if the plant is dormant and kept in a cool room, it does not need to be watered at all. The substrate in the pot should dry out between waterings.
- Sedum: growing from seeds, types and varieties
To moisten the soil, use the method of bottom watering, placing the pot with the plant in a container with soft, settled and slightly acidified water, for which several grains of citric acid are dissolved in one liter of water that has been standing for 24 hours. If you pour water under the root of a plant, as we do when watering other flowers, drops of water that fall on the stem of the prickly pear clog the pores, and this disrupts the breathing of the tissues, and cork growths form on the stems.
As for air humidity, under natural conditions prickly pear feels normal even in very dry conditions, so there is no need to spray the plant either in the summer heat or in winter, when heating devices work intensively.
Top dressing
Caring for prickly pear involves regular feeding during the period of active growth - complex mineral fertilizer with a low nitrogen content is applied to the soil once a month from March to September.
Transfer
Prickly pear does not like to be disturbed, so adult plants are replanted no more than once every 3-4 years, in the spring, before active growth begins, if there are no buds on the plant. Young prickly pears that have not reached three years of age are replanted annually.
Since the root system of prickly pear is weak, the pot for it should be shallow but wide. The substrate is made up of one part sand, two parts clay, two parts turf and four parts leaf soil and add a little expanded clay, crushed charcoal or broken brick, but in no case should humus be added to the soil mixture. Those who do not want to spend time preparing a substrate can use a store-bought cactus mixture.
The prickly pear is replanted together with an earthen lump using the transshipment method. After transplantation, the plant is not watered for a week.
No. 1. Opuntia microdasy.
My favorite is the prickly pear, also called the hare's ear. Not only is it outwardly very decorative and extremely unpretentious, but it is also a real mystery. Growing it is a pleasure, since it is impossible to predict the shape of the future plant. But in any case it will be unique.
Likes to grow in wide, shallow containers, fresh air and cool, dry wintering.
It grows as a large, branched, erect plant.

Care during flowering
Prickly pear rarely blooms at home. It's hard to say what this is connected with. Either because it grows too slowly, or maybe because it is almost impossible to create for it the conditions in which it lives in nature. However, if you are lucky and buds form on your cactus, try not to spoil your holiday with an annoying mistake:
- do not rearrange or rotate the flower pot;
- do not replant the plant;
- do not change anything in care - both watering and fertilizing should be carried out strictly in accordance with the regime.
If you violate at least one of these rules, the plant may shed its buds, or they will degenerate into vegetative shoots, and a blooming prickly pear will remain your pipe dream.
Prickly pear after flowering
When the plant has flowered, its watering is gradually reduced, fertilizing is stopped completely, and then the cactus is transferred to an unheated room, where it will remain dormant at a temperature of 5-7 ºC without moistening or fertilizing until the beginning of the next growing season.
Short description
Prickly pear is a plant of the cactus family. The vast majority of species, 190 out of 300, in this family belong to him. There are various forms: creeping along the ground, low shrubs up to half a meter in height, small trees 1.5-2 meters and large specimens as much as 6m tall. For some species, breeders have developed varieties that are winter-hardy or grow on soils unusual for cacti. Opuntia can be grown not just from seeds or cuttings; grafting operations are performed on it in order to combine the strength of the roots of the rootstock and the brightness of the flowering of the scion; for example, Schlumberger is grafted onto the sprout of Opuntia. Feeders also appeared; decorative, with a small number of needles; indoor varieties.
There are practically no differences in the maintenance of any variety at home; soil compositions, lighting, wintering, watering levels, and methods of propagation can be found in this article.
How Opuntia is used in cooking and medicine, signs and superstitions about the cactus, chemical and vitamin composition are described here.
A scion is a part of a varietal plant that is grafted onto another plant. This could be a small fragment of a stem or even one bud. The scion will form the upper part of the plant and be “responsible” for its varietal characteristics.
The rootstock is the plant or part of the plant onto which the scion is grafted. The rootstock is the lower part, which will be responsible for nutrition, stability and adaptation to local conditions.
Prickly pear propagation
Cuttings
Prickly pear is propagated by cuttings and seeds, but it is easier to use the vegetative propagation method: segments are separated from the stem of an adult plant and dried in a vertical position for three to four days, until a dense film forms on the cut. Root the cuttings in disinfected damp sand, burying the stem segments 3 cm into it and covering the container with a plastic or glass cap. Ventilate the cuttings and moisten the substrate as needed.
Rooting occurs at a temperature of 20 ºC using bottom heating. When the cuttings grow roots, young prickly pears are planted in separate pots in the main substrate.
Prickly pear from seeds
Prickly pear seeds are covered with a very dense shell, so before sowing they need to be scarified, that is, treated with an abrasive - sandpaper or a file, so that the sprout can pass through the shell. After scarification, the seeds are kept in a pale pink solution of potassium permanganate for 10 minutes, and then sown in a sterile substrate consisting of crushed charcoal, river sand and leaf soil in a ratio of 1:2:2. Don’t forget to place a layer of expanded clay in the seed container under the substrate.
Germinate the seeds under a transparent cover at a temperature of 20 ºC, regularly ventilating the crops and moistening the substrate when it dries out. Seedlings are planted in separate pots and grown for two years in good light, but without direct sunlight, and then they are transplanted into soil for adult prickly pears.

No. 3. Cristate prickly pear.
I can’t say more precisely the variety. Remember “brain in a pot”?
It began to grow actively, thanks to which it was identified as a prickly pear. By the leaves. So far this copy makes me very happy.
Diseases and pests
Pests and their control
At home, prickly pear can be attacked by spider mites, mealybugs, nematodes, scale insects and whiteflies. Mites, whitefly larvae, scale insects and their close relatives mealybugs are sucking pests that feed on plant cell sap. They are destroyed by spraying the prickly pear with a solution of an acaricide - Actellik, Bankol, Decis or any other drug of similar effect. During processing, it is necessary to prevent the solution from entering the substrate. After 7-10 days the treatment should be repeated.
As for root nematodes, it is very difficult to detect their appearance, but if you look closely at the roots of prickly pear, you can see swellings on them that these root pests form. Using a sharp knife, these formations should be cut down to healthy tissue, after which the roots should be immersed in hot water at a temperature of 45-50 ºC for 10 minutes, but in such a way that the root collar remains dry. After the procedure, let the roots dry, treat the cuts with crushed charcoal and plant the prickly pear in fresh sterile soil.
Diseases and their treatment
Among the diseases, prickly pear can be affected by pythium root rot, late blight, gray rot and wet stinking rot. The cause of these diseases is fungi, which are activated under conditions of regular waterlogging of the soil and overfeeding of prickly pear with nitrogen fertilizer. Diseased areas must be removed, and the plant must be treated with a solution of a fungicide - Bordeaux mixture, Gamaira, Oksikhom, copper sulfate or other preparations of similar action. When spraying prickly pear with pesticides, follow safety precautions.
