Black Plastic Mulching Film

[piers]

As to the fleece questions, Chrispea27, I got mine from a company called Alplas - which sell basically every type of plastic and related product. I thought it was cheap, highly efficient, and a really good find. Go to www.allplas.co.uk for info.
They also have mulching film too, and everything they do is sold by length rather than in packets. You just tell them how much you want.

Instead of using the black plastic film I buy a large roll of cheap bin bags from my local sunday market (£4 for 500 bags).   This way I don't mind cutting holes in them 'cos they're so cheap, whereas with the film it get's expensive.

Good tip CC. 

I checked out the Alplas site and the black sheet heavy quality mulch is the cheapest I've seen.  For a 50 x 2m wide roll it's £53.46 delivered.  I shall be getting some for our in bloom allotment to make paths and put between beds etc.
