Onion Weed Control – Weed Busters

Onion Weed, also known as Onion Grass or Guildford Grass, is a major problem in Perth lawns and gardens. This winter-growing weed thrives year-round in shaded, well-watered garden beds. Its underground bulb makes it tough to control manually—pulling it often leaves the bulb behind, causing it to multiply, and it’s nearly impossible to remove from lawns.

At Weed Busters, based in Greenwood, Perth, we can effectively eliminate Onion Weed from your lawn or garden. Our specialized herbicide mix targets the bulb, killing it over 4–6 weeks without harming your lawn or plants.

Our Onion Weed Services:

  • Effective Bulb Control: A herbicide mix that kills the bulb over 4–6 weeks.

  • Lawn-Safe Treatment: Protects your grass while eliminating Onion Weed.

  • Garden Bed Solutions: Safe removal from shaded, well-watered areas.
