Delphiniums thrive in full sun and rich, well-draining soil. They prefer cooler summer temperatures. Stake tall varieties to prevent them from falling over. Water regularly, especially during dry spells, and fertilize in spring. Deadhead spent flowers to encourage reblooming. They are perennial, but some varieties are short-lived and may need replanting every few years.
