Most weeds come back because their roots, bulbs or seeds stay behind. Here’s how to recognise the usual suspects and deal with each one.
The short answer: name the weed first, because the fix depends on how it spreads. Tap-rooted weeds lift out with a forked weeder, bulb weeds need digging out with their soil, and running grasses need every root removed. Get them before they seed, bag the seed heads, and cover bare soil afterwards. Restricted weeds such as Chilean needle grass need extra care, so check with your council before you move soil or slashings.
Here are common weeds in Melbourne lawns and gardens, how to tell them apart, and what works. If you’d rather hand it over, see our weed removal across Melbourne.
A low, flat annual lawn weed. Its seeds end in stiff spines, which are the prickles you feel underfoot. Gardening Australia says bindii is a cool-season weed that thrives where lawns are cut too low. So start in autumn and winter: raise the mower and feed the lawn so thick grass crowds it out. Gardening Australia’s rule for annual weeds is to get them out before they flower and set seed, so lift small patches early.
Yellow daisy flowers with a black or dark brown centre. It’s tap-rooted, so lift the whole plant with a forked weeder, which gardeners call a daisy grubber, before it flowers and seeds.
Both have yellow flowers and a taproot. An archived Victorian Government plant key tells them apart. Flatweed (cat’s ear) has rough, hairy leaves and flower stems that usually branch. Dandelion’s stems don’t branch, and its leaves have deep lobes pointing back towards the centre. The fix is the same for both: lift the whole taproot with a daisy grubber.
A bulb weed: pull the leaves and the bulb stays in the ground. Gardening Australia’s advice for bulb weeds is to dig them up with their soil, then drown them in a bucket of water for 8 to 12 weeks. For a bigger patch in warm weather, it suggests covering the area with clear plastic, pinned at the edges, for at least 8 weeks. That kills the lawn underneath too.
Clover-like leaves made of three heart-shaped leaflets, often with purple-brown flecks, and bright yellow trumpet flowers from June to October. It grows from a bulb that makes many tiny bulbs, called bulbils. Weeds Australia warns that pulling it after the bulbils form knocks them loose and spreads them, so get it early or dig out the whole plant with its soil. It also travels in contaminated soil, pots and dumped garden waste.
Onion weed takes persistence. Gardening Australia explains why: its bulbs grow “one above the other”, so pulling the top one leaves the rest to sprout, and digging can spread them through the soil. For a small patch, it suggests smothering it with cardboard or old carpet for a few weeks or months.
Glossy, succulent stems and leaves, with white flowers in summer. Every leaf node can root, and Yarra Ranges Council warns that even a tiny piece of stem will regrow. Roll thick mats up like a carpet with a rake, pick up every last piece, and keep it out of the compost. Expect follow-up over a few years. It’s also a common cause of skin rashes in pets.
Running grasses that creep from the lawn into the beds. Gardening Australia’s advice is to remove every bit of root, and Banyule City Council lists both among its environmental weeds. A firm edge between lawn and beds slows them down.

Some weeds started out as garden plants. Banyule City Council’s environmental weeds brochure lists agapanthus, English ivy, cotoneasters, broad-leaf privet and wandering trad. Darebin’s nature strip “no plant” list includes agapanthus, English ivy and arum lily. Whittlesea counts blackberry among its priority weeds.
If you’re replacing them, ask your council for local alternatives. And never dump the cuttings in a park or reserve: Banyule’s brochure asks residents not to dump weeds or garden waste.
Victoria’s Catchment and Land Protection Act 1994 declares some plants noxious weeds, and the City of Whittlesea reminds landowners they’re legally obliged to manage them on their property. Two to know about, both on the weed lists of northern councils such as Whittlesea and Banyule:
For regionally controlled weeds, landowners must take all reasonable steps to stop them growing and spreading. The City of Whittlesea warns that slashing (especially in peak flowering season), dirty machinery and contaminated soil all help spread Chilean needle grass. If you think you have either weed, don’t mow or slash that patch while it’s flowering or seeding, and don’t move soil from it. Talk to your council or Agriculture Victoria first.
Match the method to how the weed grows. These groups come from Gardening Australia:
| Weed type | Examples | What works |
|---|---|---|
| Tap-rooted | Capeweed, flatweed, dandelion | Lift the whole root with a daisy grubber |
| Bulbs | Oxalis, onion grass, nut grass | Dig out with the soil; smother patches or cover them with clear plastic |
| Runners | Couch, kikuyu | Remove every piece of root |
Two tips from Gardening Australia: weed after rain, when moist soil makes weeds easier to remove, and get annual weeds out before they flower and set seed. For dense patches, herbicides are sometimes the practical choice. Weeds Australia says so for oxalis, says to read the label first, and notes that training is normally required for some control methods. Any product must suit the weed and the situation, and be used exactly as its label says. Whatever the method, established weeds, runners and seed banks usually need follow-up.

Our weed removal service starts with a look at the weeds, the plants you want to keep and the finish you want. Then we agree on hand removal, targeted treatment where suitable, or a mix. We won’t promise a weed-free garden after one visit, because established weeds rarely work that way. If the whole yard has gone wild, start with how to clean up an overgrown garden or a garden cleanup.

Expect it to take persistence. Its bulbs sit one above the other, so pulling the top one lets the rest sprout, and loose digging can spread them. For a small patch, smothering it under cardboard or old carpet for a few weeks or months can work, but it kills the grass too.
Four common culprits: capeweed has yellow daisies with a dark centre. Flatweed has rough, hairy leaves and branching flower stems. Dandelion has unbranched stems and deeply lobed leaves. Oxalis (soursob) has clover-like leaves and yellow trumpet flowers from June to October.
Usually, yes. Moonee Valley, Hume and Darebin all list weeds as accepted in their green-lid bins. Put them in loose, without soil. For restricted weeds such as Chilean needle grass, ask your council how to dispose of them.
It slows them down. Sustainable Gardening Australia says mulch, used correctly, suppresses weed growth. It works best on clean soil, so get the weeds out first, roots and bulbs included.
