I've actually already planted some potatoes already! And yesterday I was thinking about how we get non-gardeners to start growing and reduce waste.
My idea was to dig out a bean trench which can be dug anywhere so long as its light and not too shaded.The trench is filled with fresh vegetable waste grass clippings etc from now on and then when full, covered.
In May you simply plant the beans into the soil and then all that lovely rotting stuff gets to work.
You don't need to stick to runner bean. I tried Borlotti beans last year and they were a great success.
