Tips on How to Grow Delphinium

ZONES 3-7 Easy to grow from seed, this variety will reach 5 feet tall. Blooms are a mixture of dark to light blue, violet and blush pink. Most flowers have white bees.Use a good, loose potting soil, firming it down into flats or pots with a wooden block and then moisten before sowing the seed. Cover seeds about 1/8 Of an inch by sifting soil over them. Keep moist and shaded until seeds germinate, then remove shade. August sown seed produces seed-lings that can be wintered over in a cold frame and given a permanent place in the garden the following spring. Plant delphinium seeds in early August for bloom next midsummer. Seeds germinate best when fresh. The trick in hot-weather sowing is to keep the seed box dark and cool until germination, and then gradually to admit light and air. Keep soil moist but never wet. When three true leaves show, transplant to a shaded coldframe for winter. Spread sand; inch deep, around seedlings' to discourage slugs. Set them in sunny, open places; dig deep and put in drainage. Lighten soil with peatmoss; enrich with plant food; sweeten with lime, if needed. Space plants 2 feet apart with crowns 2 inches below ground. Firm soil; water. Delphiniums are their best when 2 years old, but with care produce good bloom for three or more years. See to it that all delphiniums have good drainage, for if icy water stands around crowns, loss will be heavy. Delphiniums rarely need winter protection, even in zero sections. They don't mind freezing; it's freezing-and-thawing, and cold wet feet that are bad. When cleaning garden for winter, rake lightly around plants so as not to injure their crowns. Never move delphiniums when dormant. Before the ground freezes, bring in a box of loam and sand to use in seed boxes. A good mixture for delphiniums is 1/3 loam and sand, 1/3 peatmoss sifted and sterilized.
