How to grow Natal Grass and other Tricholaena Plants in the Garden

It is best to Ruby and Natal grass outdoors at the start of spring, once sown lightly cover the seed.

The Tricholaena plants should be spaced from 30 to 45 cm apart and like most grasses should be grown in a sunny part of the garden.

The soil type is not overly important but Natal grass will thrive in a light and well drained soil.

If starting off indoors then sow natal grass seeds about seven weeks in advance. The Tricholaena seeds should take about three weeks to germinate at a temperature of 10 to 12 Celsius.

Transplant the young grass seedlings following the last frost of spring.

How to Care for Tricholaena Plant Species

It is quite easy to look after and care for Tricholaena plant species such as Ruby and Natal grasses.

They should not be grown in areas that experience strong winds as they will flatten. Tricholaena plants thrive in a moist soil so water moderately when required.

At the end of autumn cut the plants back to the ground. If you require more plants then it is easiest to grow these grasses from seeds.
