Kutrov family. Homeland - humid tropical forests, mainly about. Madagascar: seven species are endemic to Madagascar, and only 8 species of this flowering plant are widespread in nature, the only species is native to India and Sri Lanka. In culture, the species Catharanthus roseus or pink periwinkle Catharanthus roseus became famous.

It is a small perennial shrub that grows on average up to 60 cm in height. It has erect, branched stems with opposite leaves of an oblong-lanceolate shape, dark green, with a light central vein, up to 7 cm long. The flowers are simple, with five petals, pink, lilac or white, in appearance similar to the flowers of balsam or "Vanka-wet". Under favorable conditions, the catharanthus can bloom from May to the end of September. For more than one century, Catharanthus pink has been naturalized in Italy, Asia, Australia, the warm states of the USA, Central America, and many oceanic islands

Among the various varieties of Catharanthus pink, there are plants of a wide variety of colors: purple, burgundy, blackberry, scarlet, pink with mottled specks, white with pink, etc. In addition, the varieties differ in the size of the bush, some are larger, some are more compact about 35 cm in height and 30 cm wide.

How to grow Katarantus

Temperature: Katarantus is thermophilic, the optimum temperature for growth in summer is about 25-27 ° C, in winter, with a natural decrease in lighting, a coolness of about 15-18 ° C is required. Does not tolerate hypothermia of the root system, but in an insulated pot with dry soil, it can safely stand on a glazed balcony up to + 4-5 ° C. periwinkle loves fresh air, does not tolerate placement in an unventilated or stuffy room, for example, in the kitchen.

Lighting: for a catharanthus you need a very bright sunny place, direct sun for at least 4-5 hours a day, mainly in the morning or evening. Grows well in the southeast and west window. At the end of winter and in spring, the bright sun in spring should be taught gradually so that the plant does not get burned. If the plant stands in a warm room in winter, there should be a lot of light and in sufficient quantity, if you do not have a south window, then you should install fluorescent lamps next to the flowers.

Watering: in the warm season (at temperatures above 22-24 ° C), it is quite abundant, the soil should not dry out into dust. However, avoid excessive dampness, dry the upper part of the soil by about a third - Periwinkle does not tolerate waterlogged soil.

Fertilizer: with the formation of flowers and new leaves, the catharanthus is fed with a special fertilizer for decorative flowering plants, adding it to the water for irrigation. Top dressing about 3 times a month, it is desirable to use fertilizer with the same proportion of macronutrients, for example, NPK ratio of 10-10-10. At the beginning of growth in spring, for the growth of the green mass of the bush, it can be added to the soil when transplanting humus soil, or a month after transplanting, 1-2 fertilizing with a sufficient dose of nitrogen (fertilizer for deciduous plants) can be carried out. Do not forget about the needs of plants for minerals, it is better to choose a fertilizer with a full set of trace elements: boron, copper, molybdenum, manganese, zinc, iron.

Air humidity: Catharanthus likes very humid air. It is necessary to carry out regular spraying if the hygrometer is below 50%, if below 30% you need to put the pot on a pallet with wet pebbles, expanded clay or sphagnum moss.

Transfer: annually in the spring. The soil should be loose and have a slightly acidic reaction, when choosing a soil in a store, use one that is intended for planting rhododendrons (azaleas) or conifers. You can compose the soil yourself from 1 part of sod land, 1 part of leaf, 1 part of humus, 1 part of pine bark and 1 part of fine gravel. It is important that the soil is nutritious and very porous - it gets wet easily, the earthy clod is wetted evenly, and not in places. It is bad if the water after irrigation immediately flows down the walls in the saucer! To improve the structure of the soil, we add pine bark and gravel, but do not forget about drainage to the bottom of the pot - about 2-3 cm. The catharanthus is transplanted into not too spacious pots.

Reproduction: Catharanthus is propagated by seeds, semi-lignified or green cuttings.

Catharanthus from seeds

Use fresh seeds, for example, there are Gavrish seeds for sale called Pink Periwinkle. Soak them for 3-4 hours in room temperature water before planting. A mixture of peat (universal peat soil) and vermiculite (perlite) in equal parts is suitable for sowing catharanthus seeds. Pour the soil into a wide and deep enough bowl, moisten, and microwave sterilize for 2 minutes. Seeds germinate at a temperature of 22-25 ° C, in moderately moist soil, in the dark. Therefore, the seeds should be sprinkled with soil about 1-2 mm of soil. You do not need to specially make furrows and bury, you can spread the seeds over the surface, and sprinkle with a pinch of soil on top (like salt food).

Crops should be covered with foil and placed on a warm windowsill. Seedlings will appear within a week. It is very important that there is enough light from the moment of germination. If sowing in spring, a light sill is enough, but if you want to sow catharanthus (pink periwinkle) in late summer, autumn or winter, prepare lamps for additional lighting, otherwise the seedlings may stretch out.

After the emergence of seedlings, wait for the development of two pairs of true leaves - they differ from the cotyledons in shape, and you can start picking the catharanthus in separate pots about 8-9 cm in diameter. This is not to say that pink catharanthus grows very quickly and intensively, it can take about 1.5-2 months before picking. All this time it is desirable to maintain high humidity. While the seeds are just germinating, you will cover them with foil and air them two to three times a day, shaking off the condensation. When the seedlings begin to grow, the film (or glass) will need to be removed, and the bowl should be placed in a transparent bag. Tie and open the bag also for airing, after about 2-3 weeks from the emergence of shoots, you need to accustom them to a lower humidity - untie the bag and leave it open, straighten the edges up.After picking, you do not need to put the pots in the bag.

If you want to sow a lot of pink periwinkle seeds, then it is more advisable to sow in special cassettes for seedlings, several seeds per cassette, remove the excess after germination.
