Winter vege fertiliser

Pile loads of Autumn leaves on your garden and dig them into the top 10cm of your cleared patch. Add in seaweed as well if you have access to it from the beach. Rake the soil flat after doing this. Sow over the top raked soil with an Oat and Mustard mix (Burnetts do one that is sold in stores). In spring trim the Oat and mustard seedlings and dig the whole lot into the top 10cm of soil. Your Autumn leaves would have broken down to leaf mold by this stage too.
