Dahlias are half hardy, so keep them protected from frost. Pot tubers individually between February and April and grow them on in a greenhouse or bright indoor position. Alternatively, start them outside in May, once the risk of frost has passed.

Dahlia
'Bishop of Leicester'
Introduce a touch of elegance with Dahlia 'Bishop of Leicester'. From midsummer until early autumn, this bushy peony-type dahlia produces masses of single, pale lavender pink flowers, each petal bearing a darker band down its centre. The open flower structure makes 'Bishop of Leicester' a popular variety with pollinators, making it an ideal choice for the wildlife conscious gardener. The luminous blooms contrast strikingly against bronze-purple foliage—a stunning and vibrant focal point for your borders and pots!
It's impossible to have too many Dahlia 'Bishop of Leicester' in the garden, so you’ll be delighted to hear it is spectacularly easy to propagate. In spring, snip off a few of the new shoots once they’ve reached around 8cm tall. Insert into a pot of free-draining compost, and give them warmth, light, and plenty of misting. Soon, roots will appear, and you'll have your very own 'Bishop of Leicester' offspring to weave throughout the garden.

For planting out later, use a snug-fitting 15–20cm pot filled with peat-free multipurpose compost. For a patio display, plant directly into a container at least 30cm wide and keep it somewhere bright and frost free until it can move outdoors.
Position the old stem facing upwards, with the tubers covered and the stem stump level with the compost. Tubers naturally vary in size and shape and may arrive without visible buds. Bent necks are usually fine if they remain firmly attached, so do not remove them.
Water after planting, then allow the compost to become almost dry before watering again while the tuber remains dormant. Once shoots and leaves are growing strongly, water more regularly, always allowing excess water to drain away.
Plant out after the last frost, once the plant is around 20–30cm tall and its roots hold the compost together. Space dahlias approximately 30–50cm apart in borders, allowing less room for compact varieties. Water thoroughly after planting.
Water regularly during active growth and deadhead or cut flowers often. Dahlias usually bloom from July or August until the first frost, although later-planted tubers may start in late August or September. In autumn, lift, clean and dry the tubers, then store them somewhere cool, dry, airy and frost free.
