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.
'Labyrinth Two Tone'
A new version of a much-loved favourite, Dahlia 'Labyrinth Two Tone' bears the same shaggy, dinnerplate-sized blooms as its parent, though offers a different colour scheme of soft lilac pink, violet and white. The big, showy blooms of Dahlia 'Labyrinth Two Tone' measure up to 20cm across, and are produced from midsummer right up until the first frosts. There can be few more hardworking plants in the border!
Dahlias with particularly large flowers such as this can often use a little help to stay upright. Whether you go for the natural approach of inserting a network of cut branches into the ground, or prefer reusable, metal supports; try and get your Dahlia 'Labyrinth Two Tone' installed early in the growing season. Prevention is better than cure when it comes to supporting plants! Choosing the sunniest spot possible will also help in encouraging strong, sturdy growth, as 'Labyrinth Twotone' dahlias grown in partial shade tend to be leggy and weak.

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.
