Growing Non-GMO Delphinium Pacific Giant Series Flower Seeds

Delphiniums are known to be a challenging grow and best started indoors 10-12 weeks before the frost. Pacific Giant Series seeds will germinate in 7-14 days with full lighting, then place seedlings under a grow light and harden off to an equally sunny spot either in the garden or indoors. Starts may require early staking that must be readjusted as the plant matures. Plant 3-4 Pacific Giant Series delphinium seeds ½ inch deep and 36 inches apart in organically rich, evenly moist, and well-drained soil in full sun. Delphinium is known to require considerable maintenance including staking, disease prevention, and heavy pruning and deadheading.

The most common problem with germination is cold soil. The soil temperature needs to be 60-70°F for any of the seeds to have a chance to come up. Apply a balanced fertilizer every two weeks during the growing season. Stake gently and shelter from strong winds. Deadhead the dead flower spikes as far down as the next flowering shoot begins. Prune the entire plant to ground level in the late autumn. Where harsh winters are expected, a thick layer of mulch placed above the root ball can protect the plant in case of a deep, hard freeze.
