Winter grass
Description: A bright, light green grass with fine leaves that infests lawns throughout winter. Apart from the unsightly appearance, it will continue to spread and cause damage to a lawn for as long as it remains untreated. Even when the winter grass is not evident most of the year, its root system continues to deprive lawns of space to set down its own roots, causing the lawn to continue to be nutrient-deficient and unhealthy.

Yellow nutsedge
Description: Distinctive and relatively easy to identify – stems are erect, triangular-shaped and yellow-green in colour. The leaves are also yellow-green, wide 1.25 cm bladed with a thick mid-vein and a very waxy covering. The shallow, fibrous root system often produces many nut-like tubers, which are underground food storage organs. Each of these tubers can germinate and produce new plants.

Black wattle
Description: Trees flower into a mass of yellow, replaced with seed pods that fall to the ground. On the ground the black wattle seeds from previous years (up to 50 years) form a thick mulch awaiting a fire, when they will germinate en masse, after which bare ground will transform into a grass-like carpet of black wattle seedlings. The black wattle seedlings grow rapidly upwards, competing for light and resulting in long, straight wattle sticks.
