Dahlia is a garden plant, but some species can be planted in flowerpots. It originates from Middle America. Tubers of dahlia should be planted in the end of April and during May, when the earth is warm enough. It should be planted in a sunny spot, where it is sunny 8 hours a day, if possible. The soil should be medium, humus, and well-draining. If the soil is too hard, it is recommended to add peat and sand to adjust its structure. If you want to plant dahlias in flowerpots, make sure you add a layer of boulders on the bottom to help drainage. Tubers of dahlia are planted 15 centimeters in depth. The distance between the plants depends on their height. The tall ones need 90-120, the medium ones need 60-90, and the short ones need 40 centimeters of space between them. Tuber should be planted in such way that 1/3 of the root is above the ground. After they sprout, dahlias should be watered plenty once 1-2 times a week, if they are planted in the garden or 2-3 a week if they are planted in a flowerpot. If you water them correctly, they will blossom bountifully.
