Sowing Advice

Sow  Delphinium seeds onto good quality compost or seed raising mix during late winter spring for a summer planting. Sow seed on the surface of compost. Water from the base of tray to moisten the compost then drain. We recommend germinating at 15-20 degrees C keep moist at all times, by watering from the base of the tray, do not saturate.
