Native Grasses Maintenance And Weed Control | Maintaining Lawns And Gardens

Native grasses have been used extensively for Mass Planting. Grasses such as Kangaroo and Tussock grass, some Wallaby grass and more.

The entire areas should be covered in grasses to create a robust sward capable of shading out weeds. The site should have an inspection every year in Spring and new plants should be planted into any gaps. Certain varieties like Poa and Themeda are better at shading out weeds than others and are less likely to require replanting.

In most cases, initial fertilizing is enough. On sites where there is ongoing maintenance, slow release fertilizer used annually will produce much better looking plants. In areas where ongoing maintenance isn’t possible, fertilizer can benefit weeds more than the native plants, so follow up fertilizer is not recommended.

If you want a site to look ornamental, yearly trimming of native grasses is needed. For revegetation sites this isn’t required, unless maintenance for fire control is needed.

Some native grass-like plants don’t usually require regular trimming to look good, e.g. Lomandra Longifolia Katrinus and Tanika, Dianella Little Rev etc, but these are not really grasses. For ornamental sites use a sharp knife or brush cutter. Trim close to the base. (50mm to 100mm from ground).

Avoid trimming C3 (Cool Season) grasses in summer or hot months, and avoid trimming C4 (Warm Season) grasses in winter or cold months or in dry summers. For revegetation sites, yearly trimming can be done with a brush cutter, or a slasher. If a slasher is used, rake off the clippings, do not leave them sitting on the grass.

Slash at 100mm high. A good time to slash is early Spring or early Autumn. Try to pick a time when the new native grass seed crop is not destroyed.
