29) When you’ve harvested all the greens, you can compost the remaining root mat in your own compost bin so that after two or three months of recycling your soil mats and vegetable scraps, you can use your own compost rather than having to buy it from your local gardening shop.  Doing a compost system is very simple, with a pair of bins.  To start off, take a bin, drill holes in it for drainage:

30) The bin will need to be elevated for drainage, I have used three equal height broken bricks for this.  Set them up either outside…

32) Put your remaining soil mat into the bin.

33) Chop it up with a small hand spade.

This method of reclaiming topsoil is as important a skill to learn as growing the shoots themselves.  Knowing how to produce good quality soil is essential.  The art of composting is the foundation of self sufficiency.  Just buy a handful of compost earthworms from your local gardening shop and this method is complete.  Once the first bin is full, begin filling the second, only returning to the first to turn it once a week and it will reach maturity and be ready to use again after two or three months.
