How to Grow Blue meadow grass and other Koeleria Plants

Blue meadow grass, Junegrass and other Koeleria can be grown either from seeds or tubers. The seeds should be sown on the surface, and tubers buried 5 cm deep; in the first months of spring. They like to grow in sunny areas that have good drainage, and have a preference for sandy soil. It takes from half a week to three weeks for blue meadow grass seeds to fertilize at 15 to 24 degrees centigrade.

Caring for Koeleria in the Garden

Once growing thin the young Koeleria plants to be about 20 to 30 cm apart. Members of the Koeleria genus are pretty easy to look after: they require regular watering in dry spells. Plants are short lived, and more can be propagated by dividing plants in the spring.
