Growing Instructions

Plant Indoors: The Dahlia tubers of Imperialis can be started off indoors from January to March.

Plant outdoors: Plant tubers into the garden or containers after the fear of frost has passed. This is normally towards the end of April but can be earlier in the south and in coastal areas.  Alternatively plant direct into the garden when the soil has warmed up and the fear of all frosts have passed. Cultivate soils to a depth of 20cms and plant tubers so that the top of the tuber is 5cms below the soil surface. Soils are best manured in the winter before planting as the young roots of dahlias do not like fresh manure around them.

Care Tips:

Dahlias can be left out over winter in well drained soils, just mulch to give added protection.

Remove dead flower heads to ensure a summer of flowers and remember to feed during the leaf and flower stage with something like bone meal or tomato feed.
