Delphinium Plant Care:
As with most delphiniums, a moist, rich soil is needed and regular feeding and watering are recommended. This taller variety may require staking. Lanky or bent stems can be cut back by one half to force new growth at the base. As with Digitalis and Lupines, cut off most faded flowers so they do not exhaust themselves in seed production. Allow some self seeding to ensure future generations.
