Where to plant astrantias

Astrantias thrive in heavy, damp soil, ideally incorporated with plenty of organic matter such as home-made compost, well-rotted manure or leaf mould. They’re happy in sun but will do better in dappled shade.

How to plant astrantias

Dig a planting hole, remove your plant from its pot and position it in the hole. Backfill with soil and firm in well. Water the plant thoroughly and keep watering through the first summer, especially if you have a free-draining soil. Add organic matter to increase soil fertility and conserve moisture. The plants won't need staking.

How to look after astrantias

Astrantias require very little care. Cut the foliage and flowers hard back in autumn or spring. Plants require no support.

How to propagate astrantias

Astrantias can be divided in spring. Lift the plant with a garden fork and pull the plant apart. Replant straight away or pot divisions on.

You can also grow astrantias from seed, either by collecting seeds from your own plants and sowing in late summer, or sowing shop-bought seeds under cover in spring.

In this video clip from Gardeners' World, Carol Klein demonstrates how to collect astrantia seed in autumn, and sow it straight away:

Growing astrantias: problem solving

Astrantias are trouble-free plants and are usually untroubled by garden pests such as slugs and snails. However they may be susceptible to fungal powdery mildews, which form as a white coating on the plant's leaves. In autumn, cut back the plants and dispose of, or burn the leaves. Apply a mulch to the soil to prevent any remaining fungal spores splashing up on the plants in spring. Plants that have dried out or are under stress are more likely to be a target.

Dry for cut flowers

Astrantias make excellent dried flowers. Cut the flowers in summer and hang them upside down in a warm dry place.
