In spring plant each healthy one for even more of these lovelies.
Dahlia tubers Started by BARNACLE BILL on General Gardening. Plant dahlia tubers in full sun in late March or early April using a large pot and multi-purpose potting compost. Theyre not hardy so in all but the mildest areas of the UK it is best to dig up the root tubers and store them in a frost-free place over winter. We supply dahlias as tubers available from January to March as plug plants well-rooted cuttings from March to April and as pot plants grown in 10 cm pots from April to June.
