In midland the dahlias land to the open ground during the period from June 1 to June 10. If the soil manages to get warm earlier, they can be put the separated tubers on May 15-20. Recommend to carry out this procedure in cloudy weather or in the evening.
Preparation of the site
Dahlias put on in advance prepared sites, previously having placed stakes and having dug out about them poles. The place of landing needs to be protected from wind by means of fencings, buildings or trees. Underground waters on it should not rise higher than 60-70 cm from the surface of the soil, otherwise beds and beds with flowers need to be lifted due to deepening of paths and grooves of the neighboring platform.
Soil on which dahlias grow has to be moisture capacious and at the same time water-permeable. To the earth add the fresh or rerotting manure, peat, the cespitose earth, compost of various contents, sheet humus, straw cutting and other organic materials which easily decay in the soil.
To increase water permeability of clay soil, bring coarse-grained sand, ashes, the gravel which is washed out and the sifted small coal slag. Add clay, peat or vermiculite to sandy soil. In the fall the site is deeply plowed and dug over on depth of 30-35 cm. In the spring it repeatedly digs up and carefully loosen in 2-3 weeks prior to landing.
Landing and leaving
Dahlias put at distance from 60 to 100 cm from each other, between ranks there have to be not less than 100 cm. Stakes clear 160-180 cm high, it is the best of all to choose coniferous breeds of tree, they are more durable. They should be painted with green paint, and - to impregnate the lower part with 7% solution of iron vitriol. It is possible to use metal pipes or pieces of reinforcement steel with a diameter of 12-20 mm. Stakes chuck in depth about 40 cm, near them plant plants so that the neck of tuber was located 4-5 cm below than earth surface. Hybrid seedlings and cherenkovy dahlias put on depth of 8-10 cm. Plant, received from divided tubers, before landing it is abundant spill water then accurately place in the prepared pole, trying not to damage earth lump. For convenience of watering of pole leave filled up with incompleteness or around plants create ring-shaped holes. The put dahlias tie to stakes, in process of growth continue garter. In the next days them it is necessary it is abundant to water, in the dry and hot leading role it is had daily. Further water less often, but the soil under plants always has to remain damp. After each watering or fertilizing the earth is loosened. When buds are created and green material of plant will be closed, loosening should be stopped, and the soil needs to be mulched peat or humus.
