"Yellow shades of Dahlia for bouquets brighten up your flower bed. Place the tubers in the ground in the spring, when you are absolutely sure that there will be no more frost. Dahlias bloom best if placed in full sun, but they also thrive in dappled shade. If you dream of large, strong plants, it is necessary to add fertilizer and also preferably compost.
Withered flowers are removed, this promotes flowering. The tubers cannot tolerate frost, so if you want to save them for next year, they must be dug up and overwintered in a cool place. "
