Hi all!

First post (although have been lurking for a while). I'm a beginner gardener - well at it a couple of years now but stil there is so much I haven't a clue about.

Anyway, have a particular problem in relation to couch grass. Moved into a new house a couple of years ago and have a fairly large landscaped bed to the front of the house. It was becoming over-run with weeds and grass so I've partially dug it up, removing everthing except the well established plants. Turns out there is quite a large amount of couch weed growing. Now following some investigation, I realise that it will be possible to get rid of the couch eventually. I'm just wondering if there is any point in putting down weed killer at this time of the year. I've already dug up the ground and removed some of of the weed root, and I'm going to go at it again this weekend and try and remove every single bit of root left Should I put down weed-killer once this is done, or is it a waste of time this time of the year??

Thanks for your help in advance

You could certainly put down killer targeting the couch specifically, such as roundup.

I have been through this myself, and i would have dug out before, only for the weed to return again.

I recommend hitting the couch specifically with roundup. pick a day that is dry and will remain dry for 6- 8 hours.

Couch will permanently die off after maybe three weeks. Keep hitting the couch over the spring and summer untill all is eradicated.

Your very best option might be, not to dig out but use the killer more than digging.

Hi JackieO,

If you can cover the bed with black plastic for a few months over the winter (cutting out around the big plants )you will find that the grass roots carry on growing under the warmth of the plastic near the surface so you can just remove the roots without to much effort.

Hope this helps.
