How to Plant Grass Seeds

When planting grass seed it is best to sow outdoors. The seeds should be sown in the early months of spring, and lightly covered.

Ideally Millet grass seed should be spaced about 30 to 60 cm apart, and grown in a moist and fertile soil. It typically takes about three weeks to germinate once the temperature has reaches about 15 degrees Centigrade. Millet grass prefers to grow in shady areas of the garden.

Caring for Milium

Once established Millet grass and other Milium should be watered frequently and subjected to the occasional feed.

If you require more plants and do not want the plants to self seed then they can be propagated by division in the springtime.
