How to rid nut grass from garden bed?

[Sandhya1]

How to rid Nut Grass from my Raised Garden bed. It was introduced to the garden bed by horse manure in 2021 and now its flourishing. I don't want to grow anything in the garden bed, just want to get rid of the nut grass and put something over the top so it doesn't grow back. I am renting and due to pain and reduced mobility in my back and hips i am not able to maintain anything growing in the garden bed. Sorry i don't have pictures. But the nut grass was very thick and 2 feet tall, i have it dug out and then it grows back in 8- 12 weeks.

I have just had it dugs out again a week ago and already new shoots are a few inches tall.

Hello @Sandhya1 

Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thank you for sharing your question about removing nut grass from your garden bed.

I suggest using Yates 1L Ready To Use Nature's Way Organic Weed Killer Spray. It is glyphosate free and non-residual in the soil, replanting can occur 7 days after spraying. Once you've sprayed the area, I suggest turning the soil over to try and get to the nutlets to prevent further growth.

Please make sure you are wearing appropriate safety clothing, gloves, goggles and a mask when using weedkiller spray. Please make sure to follow all the recommended safety procedures printed on the back of the bottle.

If you need further assistance, please let us know.

Hello, I have just come across your post.  I know it's over a year old but I am wondering how you got on with your nut grass situation?

I have recently moved and the home we've moved into didn't seem to have any issues with Nut grass till I started adding gardens, and of course the improvements have fed a horrid nut grass situation.  In some areas its absolutely horrid. 

I've poisoned it on several occasions, with a variety of poisons and in one area I layered 4 thickness of weed matting and crusher dust to pave an area, and OMG the nut grass has come up through all layers and thicker than anywhere else, it is so thick one would think I specially planted it and gave it the best fertilizer available. Only wish the rest of my gardens looked as healthy.  

If that wasn't bad enough. The soil I removed from the area, I put in other parts of my yard, so I have nut grass coming up everywhere in places I forgot I'd used the original soil in.  I too have physical disabilities and down on my hand knees isn't something I'm very good at. 

Thank you 

This old gal

Hi @Old-gal24,

I'm a fan of the Zero weeding wand, which you fill with herbicide. Then, you can just walk around and paint the nutgrass leaves with the brush applicator. Its length prevents you from having to bend over.
