Last year my mum gave me half a dozen bags full of leaves that she had collected from her garden. I have left these rotting away in their bags in the hope that it will make nice leaf mould to spread on the raspberry bed this winter.
To be honest I had completely forgotten about these bags until yesterday and to my surprise inside all the bags is the most lovely rich moist leaf mould that I have ever been able to achieve. Normally it is just a horrible sludge and is a bit smelly.
The raspberry bed has been weeded and it now has a 3" thick coat of leaf mould to see it through the winter. This will nourish the ground and give the raspberries a good start for (hopefully) a bumper crop next year.
