How to Grow Avens and other Geum Plants in the Garden

If growing Avens and other Geum plant species from seed, then sow outdoors at either the start of spring or autumn; lightly cover the Geum seeds once sown. Avens likes to grow in sunny areas of the garden that has good drainage; they can tolerate partial shade in hot climates. Ideally the soil that the plant grows in will be rich and slightly acidic to neutral pH (5.5 to 7).

If first growing indoors then sow Geum seeds about 10 weeks in advance. It should take three to four weeks for Avens to germinate at 18 to 21 degrees centigrade. Once ready transplant into the garden at the start of spring or autumn with a spacing of 30 to 45 cm.

Caring for Geum Plant

Geum plants such as Purple and Mountain Avens are easy to grow and look after. It is a good idea to remove dead flowers to prolong blooming and to keep them tidy. Supply a mulch in winter. When the plants begin to look tired (about four years) divide them to maintain vigor. If you require more plants then propagate by division in the autumn.
