Plant Kingsley Larkspur in well-drained soil with full sun to partial shade. Space plants about 12-18 inches apart. Water regularly to keep the soil consistently moist but not waterlogged. Apply a balanced fertilizer in early spring and again in mid-summer. Deadhead spent blooms to encourage continuous flowering. Cut back the plant to the ground after flowering to promote healthy growth for the next season. Protect from strong winds with staking if necessary.
