Plant Indoors: The Dahlia tubers can be started off indoors from January to March.
Plant Outdoors: Plant them out 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.
Our Tip: Dahlias can be left out over winter in well drained soils, just mulch to give added protection.
Remove dead flowers as they appear to encourage new flower growth.
Protect young shoots from slugs and snails and do not plant dahlias into cold soils.
When planting in the garden do not plant into freshly manured areas but of course remember to feed when the plants have shoots over 15cms.
