digging a new garden

[kiwibella]

I have planned an area for flowers alongside our fence. It is going to require some levelling which we have started by putting in a border roll. We have a stupid slope on our garden so it will require some filling to level. Do I (we ) have to take off the layer of grass? Dh doesn't think we need to... I'm not so sure .

The grass will just grow through won't it?

I would say you need to get rid of the grass. If the fill is deep enough for it to not grow through, I think that rotting grass gives off something not conducive to growing anything else.

I dug a veg patch in a similar position to your border and did eventually remove a layer of grass. I did try and dig some of the grass sod in but was really is hard to break it up and it sat as uneven lumps on the surface.

when we made a raised bed (or 4!)for our veggies, we just put it on the grass and filled it with soil.

Didn't seem to cause any bother to our harvest

and we haven't had it come up through
