How can I permanently remove grass?

Hi all!

It's my first time posting here because I'm in need of serious help with my lawn.

I've tried laying cardboard, weed killer and weed mats after removing the sod but the grass won't stop growing.

Any ideas on how we can achieve this ground is much appreciated!

Hello @brianhj 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about permanently removing your grass. 

Getting rid of grass permanently can be challenging, especially if it’s a hardy variety that keeps coming back. A strong glyphosate-based weed killer like Yates Zero from Bunnings works best when applied on a warm, dry day while the grass is actively growing. If regrowth occurs, multiple applications may be needed.
 

For a non-chemical approach, removing as much of the root system as possible and covering the area with a heavy-duty geotextile weed mat from Bunnings can help. A thick layer of organic mulch, such as sugar cane or pine bark, will further suppress regrowth while improving soil quality. If you’re not planting in the area, compacting the soil and adding pavers, stepping stones, or a layer of crushed rock like Deco Granite will create a durable, low-maintenance surface.
 

Even if you eliminate existing grass, wind-blown seeds can still take root. A pre-emergent herbicide like Yates Weed n’ Feed will help prevent new seeds from sprouting. Applying at least 10cm of coarse bark mulch will also make it harder for seeds to germinate. For paved areas, sealing gaps with Gap Sand or mortar helps stop stray grass from creeping in. Regular maintenance, such as pulling out any new growth before it spreads, will ensure the area remains grass-free over time.

Please remember to wear personal protection such as gloves, goggles and a mask when using sprays.
