How to kill unwanted grass in garden bed?

[samy]

I have inherited a garden patch from the last owners who had let the garden go wild. I removes most of the grass by hand which was growing amongst the plants. Put two layers of hardwood mulch to prevent the grass growing n the garden looked so much better. But after three weeks the grass is growing back.  How do I get rid of this grass?

Hi @samy 

You might need to put thick cardboard or black plastic to try sterilse that section of  yard for a whille till the grass is  dead and seed cooked.

Welcome to the Bunnings Workshop community @samy. It's fabulous to have you join us, and many thanks for your question about preventing grass from growing.

@Jewelleryrescue has hit the nail on the head there, as you need to remove the woodchip, lay weed matting, and then place the mulch back over the top. Otherwise, the grass will continue to grow through the mulch.

Please let us know if you have any questions.
