an easy way to grow potatoes ??

First you collect old tyres.
Carry said tyres to where you want them to be .
Then you start to fill them with expensive bought in compost ? so you carry in bags of heavy compost and put it in the tyre.
Place spuds in the tyres and start to build up the stack . In the end you could be putting tyres quite high on top of each other !!
very heavy tyres and lots of lifting and pouring of compost !!! Lots of water too...then when they are ready to be harvested you start to pull down the stack !!
Now you have VERY heavy tyres filled with wet compost , which you place on the floor and empty out , so you are now at the same level as you would be if you grew them in the soil in the first place !!! plus you have a load of compost to clear up afterwards.
MMMMM !!!! me thinks I will carry on digging, and plant them in the soil , so much less work !!! Plus my veggie plot won't look like an old scrap yard !!

cheers
