How to Grow Delphinium Pacific Giant Mixture From Seeds

Choose an appropriate bed for growing "Delphinium" cv. Pacific Giant mixture. Select a bed with full morning and late afternoon sun with light shade during the hottest part of the day. Avoid areas with deep shade or scorching hot sunshine.

Till the soil at the planting site to a depth of 6 inches using a rotary tiller. Spread a 3-inch-thick layer of compost over the bed. Work the compost into the bed with the rotary tiller.

Moisten the bed before planting the "Delphinium" cv. Pacific Giant seed mixture. Water the bed for three to five minutes using a garden hose with an adjustable nozzle set to shower or soak. Let the bed drain for ten to fifteen minutes before sowing the seeds.

Sow the "Delphinium" cv. Pacific Giant seed mixture in groups of six across the bed. Space the individual seeds 3 inches apart and the groups 1 to 3 feet apart. Plant the seeds 1/4-inch deep.

Water the seeds well after sowing. Shower the bed for five minutes to thoroughly saturate the soil. Maintain moisture at a depth of 2 inches during the germination process.

Watch for sprouting in 15 to 20 days. Spread a 1/2-inch-thick layer of compost around the base of the seedlings after they emerge to provide additional nutrients during their early development.

Water the Delphinium cv. Pacific Giant seedlings twice a week to a depth of 1 inch for the duration of their growing process. Continue watering periodically after the flowers fade.
