Tips for Growing Delphiniums

Tips for Growing Delphiniums Delphiniums are stunning perennials known for their tall, vibrant spikes of flowers in shades of blue, purple, white, and pink. To grow them successfully, start by choosing a location with full sun and well-drained, slightly alkaline soil. Delphiniums prefer cool, moist conditions, so ensure regular watering but avoid waterlogging. Plant the seeds indoors in early spring or purchase young plants for quicker results. Space plants 18-24 inches apart to allow for proper growth. Support the tall stems with stakes to prevent them from falling over. After blooming, cut back the flower spikes to encourage a second round of blooms. Delphiniums benefit from annual division to maintain their strength and vigor.
