These plants need lots of attention and like well-drained, composted soil. Feed them every two weeks with a liquid fertiliser and keep well watered in summer. They are better suited to cooler climates, and although they’re perennials, here they’re regarded as annuals.
Plant delphiniums at the back of the flowerbed and stake the long stems to prevent them from breaking or being blown over. There are also varieties with shorter stems that can be planted in the front of the bed. Delphiniums can be propagated from seed or plant seedlings in autumn.
