Peonies attract flower growers with the decorative properties long ago. It is known that in China this plant decorated gardens in the second century B.C. Because in the decorative purposes high-quality, but not specific peonies are grown up, as a rule, it is better to make multiple copies these flowers in the vegetative way.
The most widespread reproduction of peonies by means of division of bush is considered. The plants which have reached age of three-four years are suitable for this operation though the best result turns out at division of five-year or six-year bushes. Optimum time for reproduction of flowers this way in weather conditions of midland the period from the middle of August on the middle of September is considered.
From experienced gardeners it is possible to hear about division of bushes at the beginning of spring, but in this case the probability that the planting stock received at this time uses reserves of nutrients of rhizome for distillation of leaves, but not for formation of additional roots is high. It will weaken young plant and can cause his death.
The bushes intended for division dig out and wash away water the earth which has stuck to roots. For six hours of plant place in shadow where during this time they will manage to dry up slightly, and the rhizome will lose fragility. Green stalks cut off at the height of ten centimeters from roots. The prepared rhizome is divided into pieces ten-fifteen centimeters long with three-five kidneys and small amount of additional roots. If necessary delete the begun to rot sites of allotment. The received planting stock is processed against root decay, having submerged at several o'clock in the potassium permanganate solution prepared from three grams of the powder dissolved in ten liters of water. The allotments taken from liquid dry in shadow within a day, having powdered places of cuts on roots with pounded wood charcoal. In five-six hours prior to disembarkation of allotments to the soil from two tablets of medicine and ten liters of water prepare heteroauxin solution. Add fifty grams of copper vitriol and clay to liquid, bringing mix to consistence of paste. The planting stock is dipped in the received structure and dried. With mix of humus, bank sand, the cespitose earth and peat the peonies place in the prepared landing hole so that kidneys were not deeper than three-five centimeters from earth surface. To prevent excessive deepening of rhizome because of land subsidence, the landing hole is filled with soil mix a month before planting of plants. Peonies cover with five-centimetric layer of peat mulch. In some cases gardeners resort to reproduction of peonies root shanks. At this rhizome divide into three-centimetric pieces with kidney and additional root. The processed planting stock no later than the end of August is landed on bed with mix of the garden earth and compost. The distance between separate shanks makes about fifteen centimeters. Young peonies are grown within year then land on the constant place. Such plants will blossom after the peonies multiplied by large allotments, but at limited quantity of uterine bushes this way of cherenkovaniye gives the chance to receive bigger quantity of high-quality planting stock.
