Plant Indoors: Dahlia tubers are best started off indoors from January to March. Once the fear of frosts has passed they can be planted out into the garden or containers. This is usually towards the end of April but can be earlier in the south and in coastal areas.
Plant Outdoors: Alternatively they can be planted 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, as the young roots do not like fresh manure around them.
Ideal for encouraging pollinating insects to your garden.
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 tomorite.
