How to Grow Burnet and Other Sanguisorba

When growing Sanguisorba members such as Burnet outdoors from seed then sow on the surface either in late autumn or at the start of spring.

They like to grow in a sunny part of the garden, though in hot areas it may be better to grow in a part of the garden that receives a light shade in the afternoon. Ideally the soil that plants grow in will be moist, pH 6 to 8, and of an ordinary nature.

If starting off indoors it should take the seeds about two months to germinate at 10 to 12 degrees Centigrade. The seedlings should be allowed to grow for a year then put outdoors in the following springtime.

Caring for Sanguisorba

Once growing it is fairly easy to care for Sanguisorba; they like moist soil so keep well watered; supply a stake in windy areas, cut back leaves frequently (this will encourage further growth). In the spring time the plants should be supplied with a mulch. If you require more plants then they can be propagated by division in spring or autumn.
