Peat-free compost
Not so long ago Veolia would occasionally give away loads of compost made from the contents of food waste and garden waste bins. The stuff was quite smelly and it was usually still warm from the fast composting system they used. I used it mainly for mulching trees and shrubs.
The Veolia source of giveaways eventually dried up and the company has now launched a range of products that they sell online under the name Pro-Grow (see: https://www.pro-grow.com/).
I recently purchased a load of one product sold as "soil conditioner" . It comes in 30 litre bags and I can tell you that it is an improvement on the free stuff. It doesn't smell, it has been much better sieved to get big chunks of wood out and I have yet to find any of the bottle tops and small plastic toys that used to turn up in the free stuff. I am counting on this new stuff to make it easier to work my heavy clay soil and to improve yields.
