- Weeds pose a serious threat to our natural environment and agricultural industries.
- They can harm native plants and animals, natural landscapes, water catchments and can impact the economy, human health and recreational activities.
- To reduce weeds, the whole community needs to work together.
- Many weeds can travel across property boundaries and in some cases, landowners may need to take action to stop the spread of weeds.
- Council’s Weed Management Strategy outlines the actions we will take to manage weeds throughout the shire.
Trees for Weeds Day
Do you have troublesome weeds on your property? Why not trade them in for some free, local native plants.
We're partnering with Friends of Emerald Lake Park to host a ‘Trees for Weeds’ swap day. Come along with a bag of weeds to swap. Our experts will be happy to help with identifying weed species and offer advice on ways to control weeds on your property, as well as some free indigenous plants to take home.
- Date: Saturday 2 September
- Time: 10am to 2pm
- Location: Emerald Library (400b Belgrave-Gembrook Road, Emerald)
Weed control laws
- The Catchment and Land Protection (CaLP) Act 1994 is the main legislation governing the management of invasive plants (weeds) in Victoria.
- Under the CaLP Act you are responsible for managing listed noxious weeds on your property and Council is responsible for managing listed weeds on land under Council management
- Under Local Law 17 Council has the authority to ask landowners to control environmental weeds on their property and to issue fines if required

Weed control grants
We provide weed control grants to help landowners and community groups control noxious and environmental weeds on private property, both in areas of high environmental and agricultural value.

Tips for removing weeds
- 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 in reserves, as this can cause weed spread and invasion
- Make sure you have the right tools and safety equipment
- Have a look at our weed management calendar to find out what time of year to treat your weeds and which method to use
- Use a chipper or mulcher to breakdown large amounts of woody weeds (and avoid burning off). You can use the chipped material as garden mulch, as long as it does not contain any seeds, berries, bulbs, corms or rhizomes.
Cut and paint
- Cut and paint is an effective tool to remove small to medium woody weeds. 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 absorbs the poison into its root system. Ideally you should paint the stump within 30 seconds.
Drill and fill
- For larger plants 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 (ideally within 30 seconds) 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.
- You can remove seedlings, herbaceous weeds and grasses by hand. Pull or dig the plant out by hand when they are small enough to do so. All root materials 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 at seeding stage, 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.
- For herbaceous and wood weeds, carefully spray a registered herbicide directly onto the weed. Take care to avoid spraying nearby non-target plants. Avoid hot dry conditions and windy days. The best time to spray is in cool conditions in the morning.
Stem and leaf wiping
- For herbaceous plants with bulbs, tubers or corms, stem/leaf wiping may be the best method of removal. Use a dabber bottle with a registered herbicide to wipe the stems and/or the leaves of the target weed.
Use of chemicals
- Always consider natural or chemical-free options first, for example – hand or mechanical removal
- The chemical must be registered for use to control the targeted weed
- The chemical must be used at the application rate and in the prescribed manner as directed on the chemical label
- Always refer to the safety data sheet prior to using chemicals.
- All safety precautions should be taken, including the wearing of protective clothing, appropriate storage and disposal of the chemical and ensuring there is no off-target damage
- Choose the chemical that will do the job and be the least toxic to the operator and the environment
- Some chemicals are classified ‘restricted use’ (e.g. Grazon, Garlon) and legally require the person applying the chemical to have an Agricultural Chemical Users Permit (certificate)
- You can find more information about the use of chemicals on the Agriculture Victoria website
