Do dahlias need feeding?Updated 3 days ago

Dahlias often produce better growth and more flowers if they are fed fortnightly throughout the growing season, especially if grown in pots where the soil can quickly become depleted of nutrients through the growing season. However, they will still flower well without any additional feed. If you decide to feed your dahlias, an all-purpose or potassium-based feed (such as seaweed feed or tomato feed) can be applied once a fortnight during the growing season.
