What kind of soil do dahlias like -- How deep do you plant them?

Dahlias thrive in well-draining, fertile soil with a pH of 6.0 to 7.0, enriched with organic matter like compost. They prefer loamy or sandy soil that retains moisture but allows excess water to drain away. When planting dahlias, tubers should be buried approximately 4 to 6 inches deep, depending on the size of the tuber and local conditions. Ensure they are planted in a location that receives full sun for optimal growth and blooming.
