Lilac blooms in the winter.
Winter and early spring we usually we give (or get a gift) festive and bright, but habitually srezochnyh year-round chrysanthemum, carnation, rose, or indoor pot. However modest fragrant lilacs, standing at the window covered with frost pattern glass, able to cause the hero for the day real delight. But to blooming lilacs brought into the house in winter breath of spring, it is necessary to work in advance.
Lilac (common, Chinese and Persian) refers to valuable vygonochnyh cultures and in providing certain conditions may bloom in the coldest time of the year. Oust as whole plants or branches of good quality. For forcing in pots used three-five-year compact bushes of lilac, for forcing dirt - and more mature bushes. It is recommended to take the early white (double and nemahrovye) varieties of lilac colored flowers because classes, forcing fade.
Distillation lilac depending on the period of the divided into 3 groups:
- Early (late November to early January);
- Average (the second decade of January, the second decade of March);
- Late (end of March-April).
From time to make the house plants before flowering depends upon distillation: the brought before the New Year plants bloom in about 4 weeks, and after the New Year - 3 weeks from the beginning of the distillation. Accelerates flowering lilac week immersion crown 8 hours in a warm (30-35 degrees) water. In addition to the thermal baths, there are other methods of acceleration forcing lilacs (treatment of ether vapor and smoke).
Intended for forcing in pots lilac bushes are prepared in the open ground in advance: they are cut to form a beautiful lush crown and fed to lay at the ends of shoots a plurality of rounded flower buds. In early June, start to prepare the plants for transplanting into pots: undercut the root ball with a shovel around the bush straight down in a circle (at a distance of about 20 cm from the trunk to a depth of about 40 cm) to speed up the tab of flower buds and the formation of a compact root system.
In early July, bushes and abundantly watered with a lump of earth carefully transplanted into pots corresponding earthen whom size podsypaya in pots during the transplant fertile land. After transplantation substrate watered, sprayed with crown and put the pots with lilacs in sheltered from the sun and wind place; regularly caring for plants and cut emerging shoots. In early August, the bushes are fed complete mineral fertilizer. Lilac autumn watering is stopped and with the onset of frost pots harvested in a secure place (a greenhouse, shed), or dropped on the site, sprinkled on top of leaves, peat or sawdust layer of about 20 cm.
Shortly after entering into the house of lilac bushes begin to water and spray. During distillation lilac recommended temperature: not less than 20 degrees for early forcing, not less than 17 degrees at the middle and late forcing. With the onset of flowering bushes stop spraying; recommended lowering the temperature to 15 degrees - it will prolong the blooming lilac to a month.
After the end of the distillation pots with plants transferred to a bright cool room, and in the spring, when the threat of frost has passed, lilacs planted in a garden. To recover from the distillation of a lilac bush takes a year, and then they again can be used for distillation.
When forcing branches of lilacs from late November to mid-December, requires their pre-cooling during the month; optimally - at minus 5.2 degrees and 95% humidity. If the cooling temperature is higher branches (up to + 4 В° C), while the cooling increases. When forcing the second half of December to mid-January, the pre-cooling lilac branches reduced to 3 weeks.
When forcing the second half of January pre-cooling branches of lilac is not required at all. Cut with uterine bushes lilac branches tied into small bundles wrapped in paper and stored in a cool place for the necessary pre-cooling time, putting it on a wooden lattice (on shelves or on the floor). 6 hours before entering branches into the house, a solution for forcing (main ingredient: sugar - 3%; antiseptic potash alum - 0.08%; substances to improve the water regime in the shoots of: potassium chloride - 0.03% and sodium chloride - 0.02%).
After making branches in their home update sections and placed them on the first 8 hours of warm water (about 27 degrees), and then - in the solution for distillation to be updated weekly. As the consumption of the solution during forcing it regularly topped up to the original level of clean water, and a week old solution was changed to a new one.
Each time before installing branches in new fluid they update sections, making sure to cut missed the node (of flowers will wilt). The optimum temperature for forcing branches of lilac day 25 degrees at night to 20 degrees; during flowering to 15 degrees. An increase in temperature accelerates the distillation, but reduces the flowering period and the quality of flowers.
