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
'Arthur Hambley'
Have a party in pink this summer, enjoy the exuberant colour of Dahlia 'Arthur Hambley'. This showstopper of a dinnerplate dahlia really knows how to get everyone’s attention. Enormous double flowers bursting with ruffled petals and vibrancy are a hit all through the season. The colour is truly special, a rich and deep pink, getting duskier towards the centre, but lighter and softer towards the edges. With these enormous flowers, at up to 20cm across, Dahlia 'Arthur Hambley' brings life, colour and excitement to the garden and perseveres well into autumn, out- running most other summer plants with its stamina and lengthy season of interest.
Decorative dahlias make a big statement in the garden, and are equally impactful in a bouquet or vase. Just one flower of Dahlia 'Arthur Hambley' will give an instant lift to a cut flower arrangement, and blends especially well with other pinks, as well as purples, whites and creams. Luckily the huge blooms are held up on sturdy stems, and at 90cm high this dahlia is not too tall for most bed and borders. To give its very best, Dahlia 'Arthur Hambley' benefits from a spot in the sunshine, and a good watering and feeding regime. A little care will pay off dividends, with an excellent succession of flowers over a long period.

Plant calendar
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.
