Planting and Growing Potentilla

Plant outside in early autumn or spring. Container grown plants can be planted out at any reasonable time of year.

Grow in an open sunny position in any good, well drained, fertile soil. Thrives in full sun or partial shade but the flowers tend to fade in full sun.

Although shrubby forms are not the neatest of plants, Potentilla is a very useful and tough contender for the border, due to its ability to grow almost anywhere and for its long flowering period.

Taking Care of Potentilla

Water thoroughly during dry weather until well established. Mulch with organic matter in spring and apply a general fertilizer suitable for shrubs.

Pruning Potentilla

Dead-head the flowering shoots of shrubby forms and remove any weak and old stems.

Cut back perennials once the flowers have faded in autumn.

Pests and Diseases

Generally pest and disease free.

Propagating Potentilla

Seeds of shrubby forms and annuals can be sown in spring.

Perennials and shrubs can also be increased by division in October or March. One of the best methods is to take 3in (75mm) semi-ripe cuttings in the autumn and root in cold frame.
