How to Grow Miscanthus

When growing Miscanthus it is best to sow the seeds outdoors. Sow them on the surface about 60 to 90 cm (2 to 3 feet) apart for small species. Larger Miscanthus varieties should be planted singularly.

They typically take from two to nine weeks to germinate, once the temperature reaches 15 degrees Centigrade (59°F).

Silver grasses (Miscanthus) can grow in either sunny or lightly shaded areas that have good drainage.

They have a preference for moist soil, but are able to tolerate dry spells.

Caring for Miscanthus Plants

When growing Miscanthus, it is important to realise that they are very large plants. This means that they require a lot of physical effort to look after.

As they easily spread, they should be cut back to ground level in the autumn before they have chance to set seed.

Miscanthus also require to be divided about every four years in the springtime. This helps to maintain robust growth. Division also allows gardener's to obtain additional plants.
