Veggie's random garden

This is one of my new growing areas!
It used to have a roof on it with a couple of seats and a table underneath but the roofing sheets warped and, instead of channelling rainwater into a waterbutt, it formed a pond on the roof!! Rather than re-roof it, or demolish it, its been enclosed with fireguards and a safety gate - to keep the dogs and chooks out. The square beds inside are from a stacking wormery.
I've put a layer of hotbin compost in the bottom of each square and top it up with last year's tomato compost prior to planting courgettes in each one. 
The canes are from the cutdown bamboo and I'll grow something up them - beans or squashes or similar

Unusual to see straight lines and right angles in your garden?
