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
'High Fidelity'
We are delighted to bring you the newly introduced Dahlia 'High Fidelity', a stylish two-toned ball dahlia. Measuring approximately 10cm across, its flowers are on the small to medium side for dahlias, making them easy to blend with other plants in the border. The many petals of Dahlia 'High Fidelity' are apricot with a red reverse, a glowing combination which is dazzling when mixed with rich burgundy, golden, and orangey tones.
We think you’ll love Dahlia 'High Fidelity' so much you’ll be dying to grow as many as possible, so you’ll be pleased to hear it is wonderfully easy to propagate. Simply snip off a few of the new spring shoots once they’re around 8cm tall. Insert into a pot of free-draining compost, and give plenty of warmth, light, and misting. Soon, you’ll see roots appear—your cue to pot on into individual pots and grow on until they’re beefy enough to go out into the garden.

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.
