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
'Fenna Baaij'
Is it a Chrysanthemum? An Echinacea? An Anemone? No, it’s Dahlia 'Fenna Baaij'! With its particularly pronounced central powderpuff, this anemone-flowered dahlia is certain to give even the most experienced gardeners pause for thought. Soft, lilac pink and dusted with gold at the centre, the sumptuous flowers of Dahlia 'Fenna Baaij' are ideal for adding texture and summer-long interest to borders and containers. We love seeing them with swaying, buff-coloured grasses such as pennisetum and miscanthus, with a few tall, airy dierama (angel’s fishing rod) nodding above. Perfection!
'Fenna Baaij' dahlias are half-hardy, meaning they will need some form of protection from the cold and wet. If you have heavy soil or live somewhere prone to very cold winters, your best bet is to lift and store the tubers in a greenhouse or shed. If you garden on light, well-draining soil, or are in a milder area, you will get away with leaving Dahlia 'Fenna Baaij' in the ground with a thick layer of mulch.

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.
