— Plant your Delphinium (larkspur) bare roots straight outside during spring

— Soak the roots in water for 30 minutes before planting

— Grow in borders or containers in full sun or partial shade

— Spread the roots out in the planting hole so that any growing points are just above soil level, and not buried

— Space the plants about 35-30cm apart

— Water-in after planting, and do not allow the ground to dry out in summer; watering regularly during the flowering period will help prolong the flowering period
