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
'Karma Sangria'
"Viva la fiesta!" It’s happy hour all day, every day with Dahlia 'Karma Sangria', which flowers unstoppably through summer and most of autumn. A sunny cocktail of gently rolled, pink petals with a bright yellow glow at the base, forming an explosion of starburst, shaggy cactus blooms of up 15cm across. The unmissable Dahlia 'Karma Sangria' is fun and funky with pointed petal tips that add a fresh and edgy texture to planting schemes. The ever-popular 'Karma' series are bred for exceptional garden performance and cut flower qualities; prolific nature, shapely blooms, long stems and a superior vase life. Snip some for summer arrangements and enjoy the fruity burst of colour. The more you cut, the longer they party on!
Growing to a height of over 1m, Dahlia 'Karma Sangria' settles in perfectly towards the back of a border where it will radiate tropical tones through the season. You can group dahlias together or space them around the garden – either way, you’ll be in for a colourful and rewarding summer show. Dahlias which complement Dahlia 'Karma Sangria' and which flaunt the same vibrant spirit include 'American Dawn', 'Jowey Frambo' and 'Big Brother' – plant them together and look forward to a healthy helping of summer colour.

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.
