1 CHOOSE A SPOT
Dahlias grow best in moist, well-drained soil with full sun. Depending on the variety, they will reach between 1 and 8 feet tall.
2 GO SHOPPING
Some growers sell plants, but for the best variety and prices, order tubers (similar to bulbs) at an online resource such as dahlias.com.
3 PLANT THE TUBERS
Well after last frost (late May or early June), plant tubers and water them. Ideally, when plants emerge, mulch with 2 inches of hay or compost to keep roots cool.
4 KEEP THEM TIDY
When plants reach 6 inches, remove all but the strongest stem. When plants reach 1 foot and have leaves, trim tops to encourage branching. Stake tall plants or use cages.
