Dahlias provide a long period of colour in your garden. Dahlias can be started off indoors during January to March Alternatively they can be planted outdoors in the garden or containers in late March when the fear of frost has passed. To store until then, keep in a cool, dry and frost free location. Protect young shoots from slug and pest damage.
