Fort Vedge

The original idea of having a vegetable enclosure was for it to be a bird- and possum-proof. At first we built a tunnel:

In late 2010 we acquired some chooks and needed to expand the protected area, now called Fort Vedge:

We tried shade-cloth over the tunnel throughout summer and winter and found that in both cases it improved plant growth (less harsh sun in summer, less heat-loss and lighter frosts in winter) so we've made the roof out of low blockage (30%) shade-cloth.
