Amenity Land query

Hi all.

I’ve just taken possession of a piece of amenity land next to my garden which, as you can see, is rather overgrown. I’m in the process of clearing it by hand and removing all the weed roots, and am planning to put some weed control fabric down. Long term, I’m going to plant some dwarf fruit trees in the centre, and some fruit bushes round the sides.

What would the best ground cover to use? It’s 100 sq/m, so my original plans for gravel or bark chip would be quite expensive.

Thanks.
