The surrounding landscape still needs to be finished with the construction of the steps and placement of the final gravel screed. But I now have all of the beds filled with a site soil/compost mix which was placed on top of the gravel and separated with a couple of layers of fine weave shade cloth. All the beds have been planted out and should produce a fine crop of onions, garlic, broccoli, cauliflower, mizuna, rocket, endives, tomatoes, sugar snap peas, chillies, leeks, baby carrots, thyme, coriander, parsley, basil, oregano, watercress and more. Not only will we have great produce, but it will be just about free compared to doing a normal shop.
One further musing about carbon is that these beds are all about converting cellulose molecules of plants to proteins that we can use to fuel our own lives, quite literally, and it is based upon the fact that the carbon atom has four valence bonds that are able to be reconfigured to suite very specific purposes. We - the people of the World - depend upon carbon to make us and fuel us, but if we're not careful, the misuse of carbon will be our very undoing.
