Delphinium Cultivation
Delphiniums are heavy feeders and thrive on a diet of well rotted manure, dug well into the soil prior to planting. They must nave fertile soil with good drainage. In dry summers, they should be kept watered. Feed during spring and summer with a well balanced fertiliser, preferably not too high in nitrogen. Unobtrusive staking should be in place early in the season; use twiggy bits such as hazel or beech primings adding larger pieces as the flower stems rise. Protect the crowns and emerging shoots with generous sprinklings of coarse grit. For a second, rather smaller flowering, cut down the spent stems and foliage to ground level after flowering than water and feed well thereafter.
