Preparation of ground before laying raised bed

Hi,

Im going to put raised beds in my garden in the next few days. They are going to be laid on an area which is currently grass with no weeds. Do I need to lift the grass and then put weed killer or some kind of treatment down before I fill the raised beds with soil or once I remove the grass am I good to fill the raised bed with a compost/top soil mix?

Thanks

 

I did exactly as JWK has described when I did mine.

Brilliant, thats great news as then I wont need to wait on getting started and its providing future nutrients. Im going out to get the wood for my raised beds this afternoon hopefully

 

Will do....I'll do some before and afters!

 

Hello, I have the beds built at last. There was a bit of a delay because of a timber company messing me around with prices, the wood also needed to dry out and I also caught a virus. I will upload some pics. I just tried but it didn't work as the photo was too large so I need to find a way to shrink it down but I am ready to plant....I just need a dry day!
