How to Grow

Dahlia seeds need to be planted in well-drained soil that is rich and fertile. Sow seeds indoors 4-6 weeks before the last expected frost. These seeds should only be planted at a depth equal to their own thickness. Lightly cover with soil or peat moss. After all danger of frost has passed, seedlings can be transplanted outdoors directly into the garden or containers. Dahlia care includes deadheading spent blooms to ensure a continuous supply of fresh flowers. Apply a high nitrogen liquid fertilizer weekly in early summer, then a high potash fertilizer every week from midsummer to early autumn.
