Sun! American Dream dahlias in general like the sun, lots of it. Furthermore, you need to plant them correctly. Firstly, you need proper soil preparation: dahlias prefer well-draining, fertile soil that is slightly acidic. Before planting, amend the soil with compost, peat moss, or other organic matter to improve its quality. Then, plant the American Dream dahlia tubers about 3-4 inches deep in the soil, with the “eye” facing upward. Cover the tubers with a little bit of soil, leaving only the tip exposed.
They need consistent watering to prevent the tubers from drying out. Water the plants deeply, about once a week. Or even more often during hot or dry weather. American Dream dahlias require full sun exposure, at least 6 hours a day, to grow and bloom well.
