strawberry towers forever!

I  managed to squeeze in a site /networking visit this week - between all the administrative and and hunting visits. Here's Alain Darroze's 'strawberry tower'. A one metre or so high, and the same in surface area, 'tower' made with hazel branches and twigs and filled with compost. There are 250 strawberry plants in here (on 1 square metre of land). Different varieties of course. And they will ripen at different times according to their aspect to the sun.  Permaculture in action!  Stacking, minimum use of resources and labour, maximum output.
