Traffic Lights and Zones

You "think" I have a choice of growing areas but, in practice most of the garden is unsuitable for growing annual vegetables because its too shaded by the trees. There are 3 oak trees with trunks too big to hug, plus ash trees in my garden and the neighbours. Also, lots of fruit trees so the middle of the garden is no use for growing anything that needs sunlight. Even the Far end (Veg Plot) of the garden is in the shade during the day so not the best of spots.
You have to grow with what you have!
