Weed removal techniques

  • Where possible, choose non-chemical methods of weed control.
  • If the weed spreads by seed, consider the most appropriate way to remove the weed without spreading seeds.
  • Think about how you will dispose of the weeds. Never dump your garden waste on roadsides or reserves as this can cause weed spread and invasion.
  • Make sure you have the right tools and safety equipment.

Use to dispose of woody weeds

Use a chipper or mulcher to breakdown large amounts of woody weeds (to avoid burning off). Use the chipped weeds as garden mulch provided it does not contain any seeds or berries.

Use to remove woody weeds (small to medium)

Clear away any other vegetation from near the weed. Use secateurs, loppers or a hand saw, to cut the stem of the plant as close to the ground as possible. Use a dabber bottle with a registered herbicide, to paint the stump immediately. Acting quickly will ensure the plant draws the poison into its root system.


Use to remove woody weeds (large)

Use a drill or chisel to make a 2-3cm hole, at a 45 degree angle, as far down at the base of the tree as possible. Quickly fill the hole with a registered herbicide. Repeat every 3cm around the base of the weed.

If there are exposed roots, drill and fill these as well.

Use to remove woody weeds (large)

Use an axe to chip around the base of the tree (not too deep as you don’t want to ringbark it). Place herbicide into the cuts.

Be careful not to spill or use too much herbicide.

Use to remove seedlings, herbaceous weeds and grasses

All root matter should be removed to avoid the plant re-sprouting. Cover any exposed soil with organic matter to reduce more weed growth.

If the plant is seeding, either cut off the seed heads or place a bag over them before removal to reduce the spread of the seed.

Use a trowel or long knife to help loosen the soil for plants with long tap roots or bulbs.

Use to remove herbaceous or woody weeds.

Carefully spray a registered herbicide directly onto the weed. Do not to spray on untargeted plants. 

Use to remove herbaceous plants with bulbs, tubers or corms.

Use a dabber bottle to swipe the stems and/or the leaves. If needed, use a tool such as secateurs or a knife to help.

Use proper safety measures when using a dabber bottle. 

Dabber bottles have 3 parts including the bottle, sponge and lid. 

  1. Fill the bottle with undiluted herbicide (such a glyphosate)
  2. Add a drop of herbicide dye if it is available. This will allow you to see what areas have been treated. 
  3. Push the sponge stopped all the way into the bottle and ensure it is inserted properly.
  4. Put the lid on the bottle.
