Before sprouting dahlias, they should be prepared. The landing process must be carried out in early May. Cool and humid weather can stand, but this only contributes to the formation of a strong root system in dahlias. Thanks to this, the development of flowers will be much better. Dahlias are not afraid of transplanting into the open ground and take root well.
Before sprouting dahlias, at the initial stage, dried roots are cut and sprinkled with fine charcoal. Then the tubers are transplanted into a box, which should be filled with peat, sawdust or fertile soil. The tubers should stand on a well-lit window sill at a temperature of 18-23 C. It is advisable to harden the seedlings so that the plants are healthy and resistant to bad weather conditions. The box can be periodically taken out into the open air, but you need to monitor the temperature and humidity in it.
Transfer
After at least 15 days, tubers are divided. They are dug up, washed and cut. It is necessary that the tuber with the neck should have not one, but several sprouts. Before sprouting dahlias, you need to prepare pots or boxes with cells. Then the separated tubers begin to germinate in them. The bases of the sprouts are left at the very surface and do not fall asleep, otherwise the tubers will not develop. Before planting dahlias in open ground, the tubers are treated with weakly diluted potassium permanganate. Only those tubers that have sprouted and prepared for planting are planted, otherwise all the work will be meaningless. Dahlias are planted in open ground not earlier than the beginning of June, and under the film in mid-May.
You can learn all about dahlias by reading a lot of literature devoted to this flower. We will try to highlight the main points. It is known for certain that dahlias are light-loving plants, so it is better not to plant them in the shade. Wells for planting should be deep, with a diameter of about 35-40 centimeters and a depth of one bayonet shovel (25-30 cm). Typically, tubers are planted in two rows on a meter bed. The distance between tubers of undersized varieties should be at least 50 centimeters, and tall - 80 centimeters.
The dug hole is filled with humus or compost. Complex fertilizers are often used. Fertilizers in an amount of 50 g are mixed well with enough soil to feed and added to the hole. Tubers are placed in the hole strictly horizontally, which contributes to the formation of new roots from the shoot. With a vertical planting, root growth occurs on an old tuber, and this can ultimately lead to spoilage and loss of variety.
The tuber with the sprout is sprinkled so that the place where the neck of the tuber attaches to the sprout is sprinkled with a layer of soil with a thickness of 4 cm or more. The hole is made shallow. If the ground is a little wet, then dahlias are not additionally watered.
Tall Dahlias: Care and Growing
Tall plants need garter and processing. In front of each planted tuber, a peg is driven in so as not to damage the overgrown dahlia root system. If the soil was treated superficially, then dahlias do not tie, since they will already be quite stable.
Recommendations
Before germinating dahlias, it is necessary to take into account the points described above. Although these flowers are unpretentious, they still need to be sprouted correctly so that they do not cause trouble in the future and only delight you with their beauty.
