A group of TOP folks met to be shown by Gary how to grow potatoes in old tyres.

A stack of tyres was filled with compost...
and seed potatoes were added.

To use the space efficiently Gary planted a jerusalem artichoke in the triangle between the three tyres.

 

A combination of water and comfrey tea was poured onto the tatties...

...and the tyres were covered with sheets of glass to speed up the growing process.
