Dahlia Karma Serena

Dahlia tubers can be planted 10cm deep in fertile well drained soil, outdoors in spring when the frost has disappeared. They prefer to be in a sunny location and spaced at approximately 45cm apart.

In areas where there is extreme cold, dig up dahlias and store in a cool peat over the winter. Apply a high potash fertiliser every few weeks in the summer to help growth and they can be dead headed when necessary.
