HELPFUL TIPS ON GROWING DELPHINIUMS
Delphiniums are perennials that have two blooming cycles, one in early summer and if cared for properly again in late summer or early autumn. Blue is the most common Delphinium flower but there are numerous hybrids available in shades of pink, lavender, red, white and yellow. Blooms may be single or double.
Delphinium planting is normally at the back of the bed, where flower spikes can reach 2 to 6 feet tall. Delphinium flowers are often planted in groups.
Grow in fertile, well-drained soil in full sun to light shade, with shelter from strong winds.
Soil should not dry out. Water plants during the summer if rainfall is less than 1 inch per week.
Mulch helps retain moisture and keeps roots cool.
Care should include regular fertilization in spring when the plant begins to grow, and during the flowering period.
Deadhead the first blooms in early summer. Remove flower stalks when blooms are spent.
Taller varieties may require staking.
