How to grow Natal Grass and other Tricholaena Plants in the Garden
It is best to sow 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 (12 to 18 inches), 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 (50 to 54°F).
Transplant the young grass seedlings following the last frost of spring.
