Herb Weeds
Weeds because: They dominate areas and push out native plants. Many have escaped from gardens into the bush. Overgrazing promotes spiny plants. Plants with spiny seeds can attach to animals. Annual weeds can leave areas bare in the late dry and lead to erosion in rivers.

Methods for control
Slash
Slash tall annual plants well before seeds ripen.
Burn areas
Burn piles of cut and/or dry plants to kill accumulated seeds on the ground.
Cut & Spray
Disturbed soil promotes many herb weeds. Slash or remove plant material, or wait a few weeks and then carefully spray.
Control Grazing
To reduce spread of prickly seeds and allow native plants to recover.
Cut & Paint
Cut woody herbs to ground level with a brushcutter and paint or spray with herbicide.
Replace
Plant or seed native plants to increase competition.
New Plants
Learn to identify leaves on new seedlings and carefully spray. Hand pull in small areas.
Dont Spread Seeds!
Seeds can be spread from muddy car tyres, shoes and car radiators. Prickly seeds can attach to clothes and swags. Check when leaving sites that your not taking weed seeds with you!
