Zero-Waste Gardening came out of the difficulty I had finding out crops yields and areas when planning  gardens. I tied it into the wider concerns about waste and making the most of the planets resources.

I go through over 60 planning-for-yield guides for key crops to help you work out how to make the most of the green space you have got, what to grow easily in it, and how much you will harvest seasonally for zero waste.

There's some wider stuff in there too about organic gardening,  cooking techniques, and edibility tips including which crops you can eat straight away.
