Dahlia 'Alva's Doris'

Dahlia 'Alva's Doris' is a tall-growing, semi-cactus dahlia, with large, red spiky blooms in contrast with dark green foliage. It's ideal for growing in a mixed herbaceous border and is excellent for cutting and exhibiting.

For best results, grow Dahlia 'Alva's Doris' in full sun in fertile, well-drained soil. Stake plants early on to protect blooms. Deadhead regularly and feed with a potash-rich fertiliser to prolong flowering. Lift tubers after the first frosts and store them in a cool, dry situation until March, and then pot them up and keep them in a temperate greenhouse before planting out in late May.
