How you will receive your bulbs:

Selected by our team of experts and sent from our nursery, you will receive your bulbs in a breathable mesh bag. This is to keep the bulbs together in a pack that is nice and airy – perfect to keep the bulbs healthy while in transit.

Can’t plant straight away?

Keep your bulbs in a cool, light, and dry place and preferably hanging on a hook so that air can get to the bulbs at all angles. Ideally, you should aim to plant your bulbs within a week of receiving them, but if this is not possible, store them in a cool, dark place until you are ready to plant them.

Planting tips and hints:

Start dahlia tubers indoors in March or early April. Half-fill 2L pots with multi-purpose compost. Place a tuber in each pot with the central stem pointing upwards, and fill the pot with more compost so that the tuber is covered. Water lightly and place in a frost-free greenhouse or a sunny windowsill. As shoots start to grow, pinch out the growing tips to produce bushy plants. Remove all but around 5 shoots completely, to encourage the remaining shoots to grow strongly and produce more flowers.

Feeding and aftercare:.

Harden off plants and plant outdoors after all risk of frost is past. Plant in a sheltered, sunny spot in soil enriched with well-rotted farmyard manure or garden compost.

Water regularly in dry periods and deadhead to prolong flowering.

In cold areas, lift tubers in autumn and store in a cool, dry, frost-free place indoors. In mild areas, apply a thick mulch in autumn to protect against frost.
