No Bob's not my uncle, he's my brother, but that's a story for another time. lol.

>I don't want to leave it there so does anyone have any suggestions?

You could try sliding under it with a spade and lifting it that way.

Alternately, just go ahead and build your no dig bed, and then when you're getting ready to plant there, just sharpen up the spade and slice out a section of the mat as you go. By that stage your grass would have died off and weakened enough to make the job a lot easier.

Mow the grass with a very low blade before you start.
Don't use weed mat - it is c#$p!
Use very thick layers of newpaper - at least 10 sheets. Water each layer as you go. Compost or manure on top of the newspaper.
Then lucerne hay - about 10cm, not fluffed up - straight from the bale in thick chunks. Water it well. Sprinkle with lime and blood and bone or superphosphate, or dynamic lifter - more compost or manure - water well again.
Then a thick fluffy layer of oaten or wheaten straw. Expect a few oat or wheat to grow from it, but it lifts out easily and can be laid flat on top for further mulch. water well again.
Leave for a while - more than 10 minutes is good. I leave mine from 6 to 8 weeks, by which time the lucerne is getting pretty rotten and mouldy. The newspaper should still be forming an excellent barrier even if anything is still alive underneath it. Did you overlap the layers of newspaper well?
Why did you put down weed mat?

I think the mesh Reilly refers to is that stuff they use in lawn growing. I'm not sure if it's something to do with erosion or birds (who knows?)so I think it was already there.

If you put a good layer of mulch you can leave the mesh in place. No dig gardens as Sparaxis described can be layed on concrete as long as there is drainage. The thing is to put straw thickly, not to dig to the mesh and when you have finished with the first crop repeat the whole process again.

Many thanks for the replies - yes the plastic mesh is the stuff that the turf was grown in (through?) and we did inherit it. I would prefer to get rid of it entirely so instead of ignoring it's existence I have put down newspaper with a view to 'numbing' the grass and hopefully it might be easier to rip up. I should just ignore it but for some reason it really irritates me. Probably because I've spent 2+ years improving this garden slowly but naturally and to find this additional plastic rubbish just makes me want to scream.

Novice me.
What is the main idea in a no dig garden?
Is it that there is too much clay in the soil or is it to start a garden on a hard surface and save on digging?

It is an enormous saving on digging, and if you have clay soil, there is a good chance you have worms in your garden, who will pblige by doing the heavy spade work for you, and mix the straw and manure back down into the garden, so every year your garden improves.
It also means you do not have vegies growing from hard dry soil which is impossible to keep moist, especially if youare on restrictions, and difficult to keep weed free.
Weeds WILL grow in your no dig garden, but not many, and they are usually from the straw i.e. wheat, barley or oats. They pull out easily as the roots are only down in the straw.
The lucerne and manure provide many of the nutrients your plants require.
If you are elderly or have back trouble, your no dig garden can be raised up high enough to work from a standing position.
