My rooftop farm

We have a square rooftop at our house that I am slowly covering with pots full of veges. Currently I have five pots of various sizes and one parrot cage. The pots are filled with lettuce, celery, spring onions, bok choi, spinach, marigolds, rocket, fennel and various herbs. I’ve constructed them using permaculture methods, creating layers of organic matter covered with soil. So far they are thriving and I haven’t bought a salad pack in ages. The parrot cage houses a tomato plant. It is an experiment to see if I can protect them from the ravenous neighbourhood monkeys!
