Peresia - flowering deciduous cactus
The status of the most ancient cacti in Peres is disputed, but here they are certainly the most original. Unusual bushes with real leaves and romantic blooms are hard to mistake for relatives of familiar indoor cacti. Dangerous and beautiful thorns only emphasize how extravagant this plant is. Not the most undemanding to conditions, pereskia easily dump their legendary leaves. But all the same, they remain easy to grow succulents, which easily add variety to home collections.
Representatives of the genus Peresky are considered relict and perhaps the most ancient cacti - unusually bright flowering, dangerous thorns and graceful leaves. They are highlighted in a special Pereskiev subfamily (Pereskioideae) and are found in nature only in Latin America.
Peresia is often used as rootstock for other species of cactus. In Brazil, you can enjoy their buds, leaves and a special delicacy - fragrant, unusual, very tasty fruits, known as Barbados gooseberries and climbing lemon.
Peresia, or Peirescia (Pereskia) - original representatives of cacti. These shrubs and tree trees in nature can reach gigantic sizes and are able to survive in the harshest conditions, storing moisture in the stems. But outwardly, they are much closer to herbaceous plants - with deep roots and thin, branched, woody stems. In the axils of the leaves, beautiful areoles are hidden with very large, sharp and hard spines - single or bundled, silvery or dark brown.
The true leaves of the Peres lanceolate-oval, with a pointed tip, resemble laurel leaves. With a length of up to 10 cm they are shiny, leathery, with different shades of green in species and varieties. They fall in uncomfortable conditions and at rest, often fade.
Peresky summer bloom reminds of dogrose and roses due to the tenderness of the petals and the lush hemisphere of bright stamens around a very large pistil. Flowers from 4 cm in diameter, single or collected in inflorescences, fragrant, with delicate cream or pink colors.
After flowering, edible, yellowish-blushing, up to 2 cm in diameter fruit cones begin to develop. Some cross-sections on the originality of fruiting can compete with prickly pear, forming whole clusters. After the fruit begins to ripen, the hidden areoles on it begin to swell and grow into new buds or lateral shoots, as if the fruit were branched at the apex.
Types of indoor peresk
Pereskia orange (Pereskia bleo) - a plant with oval, large, matte leaves decorated with a wavy edge and flowers resembling red-orange roses, alternating with bright cones of inedible fruits.
Pereskia prickly (Pereskia aculeata) Is a winding species, forming very dense bushes with large lanceolate leaves and long spines. Similar to rosehip flowers, fragrant, wide open, pale cream flowers with bright orange stamens cover the bush in bulk. There are many forms and varieties with reddish leaves.
Pereskia large-flowered (Pereskia grandiflora) is valued for pale pink, large flowers in bundles of inflorescences, accentuated by dark leaves and very long spikes.
Pereskia Webber (Pereskia weberiana) - a very beautiful densely branched look that is easily formed. Small bright oval leaves and abundant flowering with snow-white flowers seem strikingly romantic.
U peresky has the most outlandish fruits pereskia large-leaved (Pereskia grandifolia) with its bunches on the fruits, consisting of ovaries and stems with fancifully twisted purple flowers.
Growing conditions for indoor peresk
In order not to be disappointed in this unusual cactus, it is worth treating the selection of conditions with the utmost care. If you provide pereskii access to fresh air, her favorite warmth and bright lighting, there will be no problems with care.
Lighting and placement
Pereskia are among the most photophilous cacti, do not welcome artificial lighting and bloom only on sunny windowsills. You can place them even on the southern windows. Direct summer sun often leaves burns on the leaves, but simply moving it away from the glass or shifting it to a place next to the window sill at the height of summer will easily eliminate this problem. In partial shade, the bushes stretch and do not bloom.
Preservation of the level of lighting for the winter, rearrangement on a bright window sill is one of the conditions that allows peresiya not to lose all the leaves.
Temperature and ventilation
Peresia love fresh air. Drafts are not dangerous (if there is no sharp jump in temperature and the plant does not bloom). Ventilate the premises as often as possible. Whenever possible, it’s best to place the pereskia in the fresh air, choosing warm places protected from precipitation.
In the summer, Pereskis feel great in warmth. With room content, it is better to maintain a temperature of 21 to 23 degrees. In the fresh air or with constant ventilation Pereskia tolerate any heat.
The ideal temperature for wintering is considered to be about 15 degrees Celsius. Below 10 degrees, the temperature should not fall. An increase in indicators to the usual indoor ones requires lighting control, frequent ventilation and impeccable care.
Care for the census at home
Accurate watering, rare top dressing and attention - these are all the measures that pereskiye need to maintain decorativeness.
Watering and humidity
For transplantation, active irrigation is carried out only during the growth period, but it is better not to completely dry the substrate even in winter, because in case of drought, the crossflow discards the leaves. In spring and summer, the soil is allowed to dry in the upper third of the pot, immediately draining the excess from the pallets. For winter, watering is reduced. Humidity must be changed gradually.
Despite the dislike of high humidity, it is better to include “refreshing” sprayings with warm water to maintain decorative leaves. The higher the air temperature, the more often they need to be carried out, up to daily in the summer. Dust is removed by washing the leaves, wiping destroys the protective coating.
Fertilizing and fertilizer composition
Fertilizers are applied for this cactus only in liquid form and only during the period of active growth. Enough 1 fertilizing per month with special fertilizers for succulents and cacti.
Pruning and shaping
It is easy to form even bonsai from peresky. They perfectly tolerate pruning in spring and summer, provided that at least 1-2 internodes are left on the shoots.
Transplant, containers and substrate
For peresia, a very loose substrate with a pH of about 7.0 is needed. 40-50% of loosening additives guaranteeing high air permeability of the soil (coarse sand, perlite, stone chips, gravel) should be added to the usual soil mixture for cacti and succulents.
This cactus is transplanted only as necessary - as soon as the roots fill the space of the pot. Young cacti can be transplanted several times a year, adults often do not need to "touch" for several years.
For peresk, they use sufficiently deep containers corresponding to the unusually powerful root system for cacti. A high drainage layer is required.
Peresia does not tolerate contact with the roots, they are carefully transshipped. Watering after transplantation should be extremely accurate before the rapid growth.
Diseases, pests and growing problems
Peresia - one of the most sensitive to waterlogged cacti, extremely susceptible to rot. For any signs of damage to the stems, the root of the neck or roots, you must immediately adjust the conditions and care and begin treatment with fungicides. An emergency transplant most often leads to death.
Of the pests for peres, all insects loving dry conditions are scary - spider mites, mealybugs and thrips. It is better to fight them immediately with insecticides.
Blanching or dropping foliage, stretching the shoots always indicate an excess or lack of light. Growth disorders most often occur with irrigation disorders.
It is very difficult to grow cross-seed from seeds because of low germination and extreme sensitivity of seedlings to any increase in humidity. Sowing is carried out to a depth of 1 cm, in very light soil. At temperatures up to 21 degrees, the plants are kept in light moisture under a hood. Diving is carried out very carefully in the phase of 4 leaves, but it is better to choose seeding immediately in individual containers.
At home, pereskia is often propagated by stem cuttings. You can cut them in spring and summer, using segments of stems with 1-2 internodes. Rooting cuttings easier in sandy soil under a hood, at a temperature of 25 degrees. When rooting in water, you need to carefully plant cuttings, trying not to contact the roots.
