The modern delphinium is one of the most
spectacular and popular of garden flowers. There are
wide ranges of colors, several flower forms, and varieties
of different heights. Hobby growes strive to produce
the largest individual flowering spikes possible.
PLANT RIGHT: Select a sunny location and a soil as deep and rich as
possible. In early spring set plants into a well prepared soil. If the soil is
tight or does not drain well, place a layer of rocks and gravel some 12 to 18
inches under the ground level. Work 1 pound of fertilizer per 25 square feet
deeply into the soil. Set plants 2 feet apart, pressing soil tightly around
SUMMER CARE: When plants are about 2 feet high, stake with bamboo
poles. If moisture is needed, it is best to flood the soil with water, rather
than to merely sprinkle. Keep the surface of the ground loose and free of weed
FEEDING IS NECESSARY: One month after transplanting, work 1 rounded
tablespoonful of Fertilizer into the soil around each plant. Soak the plant
food into the soil. Soon after blooming, delphiniums should be cut back and fed
in order to induce a big second crop of bloom.
DIVIDING: About every 3 years it is necessary to divide roots. This
is an early spring job, just when the shoots axe breaking through the ground.
Dig plants carefully, wash dirt away, cut clumps into sections, each with
plenty of fibrous roots and one strong stem. Plant immediately in
well-pre-pared fibrous soil, setting plants so the crowns will be 2 inches
below the surface.
PROPAGATION BY CUTTINGS … is simple and, easy. In the early spring
when the shoots are about 2 inches high, dig the soil away, exposing the crown
of the plant.
Use a sharp knife and slice a thin heel from the crown. Place in water for 2 or
3 hours, then re-move and dust with sulfur before placing in moist sand. Keep
partially shaded and moist. After cuttings have taken root, move into 3 or
4-inch pots. They should be ready to transplant into the garden in about 5 to 7
DELPHINIUMS FROM SEED: Good seed is necessary to produce good plants.
Hand pollination is generally preferred. 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.
