Essential Guidelines for Growing Stunning Delphiniums

Plant delphiniums in full sun with fertile, well-draining soil enriched with organic matter. Water deeply at the base of the plant to keep the soil consistently moist but not waterlogged. Fertilize with a high-phosphorus fertilizer in early spring to promote blooming. Stake tall delphinium varieties to support their growth and prevent flopping. Watch out for aphids and powdery mildew, and treat with insecticidal soap or neem oil as needed.
