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
'French Cancan'
Big, blousy blooms in soft, sunset hues set Dahlia 'French Cancan' apart from the crowd, somehow flamboyant yet subtle at the same time. Each petal is a pale, creamy orange with a warm, peachy pink underside, and has a slightly twisted form which means both colours can be seen together. Measuring approximately 13cm across, the flowers of Dahlia 'French Cancan' are large enough to make an impact, though not so big that they can’t be mixed with other plants in a border or container display. AKA just right!
Give your 'French Cancan' dahlias a head start by potting the tubers up as soon as they arrive, and, if this is before the last risk of frost has passed, keeping in a cool, frost-free environment until it is safe to plant them outside (usually around mid to late May). Pinching out the growing tips when they reach around 20cm tall will give you extra bushy and floriferous plants.

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.
