Plant geranium bareroots at the earliest opportunity following delivery. Should soil conditions prevent planting directly into borders (if soil is frozen or waterlogged), perennial geraniums should be potted up, watered sparingly and grown on in a cool position. Choose a sunny or semi shaded position on moist, well drained soil. Work some compost or general fertiliser into the top 20cm of the soil. Dig a hole wide enough to accommodate the bareroot with its roots spread out and deep enough that the crown of the plant is just a few cm below soil level. Backfill the hole with soil and firm the plant in gently. Water well to settle the soil.
Water regularly until fully established. Remove old foliage and faded flower stems throughout the growing season to promote continuous fresh growth. In autumn, cut the foliage back completely. Apply a mulch of well rotted manure to the base of the plant in spring. Lift and divide hardy geranium plants every third year to maintain their vigour.
