Requirements For Growing Dahlias
Light: Dahlias require full sun, meaning 4-6 hour of sunshine.
Drainage: The one major requirement to growing Dahlias is that they absolutely require excellent drainage. Dahlias are prone to freezing and/or rotting if planted in heavy clay or poorly drained soil.
Fertilizer: Dahlias are heavy feeders and do best with a regular supply of fertilizer. Begin to apply a water-soluble bloom-type solution about one month before they begin to set buds, and continue feeding every 3 to 4 weeks through the growing season.
Pests: The major pest of Dahlias are slugs. Additionally, deer like Dhalias and will devour them. Be sure to protect plants as needed.
