Plant Delphinium out in sheltered sunny borders in moist well drained soil. Incorporate plenty of well rotted manure or garden compost into the soil prior to planting. Water well to settle the soil.

Feed and water regularly until plants are established. When shoots reach a height of 30cm, the tall stems will require staking with garden canes for support. Remove old delphinium flowers as soon as they fade to encourage another flush to be produced later in the season. In autumn, remove old foliage and apply a mulch of well rotted manure to the base of the plant. Lift and divide in autumn every third year to maintain their vigour.
