Potato Towers.

Potato tower

Before you plant your potatoes this year. We have all seen the hype about potato towers, but do they work? 
​Well a potato breeder in the USA decided to check for themselves. Their results:-
not the way they are supposed to work  reasons:- 

• Hilling up much beyond six inches brings no benefits and is likely to reduce yield.
• The purpose of hilling is not to stimulate production of tubers, but to protect the tubers from the environment.
• Potato yield is primarily limited by foliage area, not by the amount of soil above the seed tuber.
• Conventional container growing works fine with potatoes but potato towers don’t work.

This would match what I found last summer and I thought  it was only me.
IF  it is space saving your after then the suggestion is to put in extra layers of seed potatoes as you go up. That is plant with alternating layers of potatoes, dirt, potatoes, straw, potatoes and dirt. 

​Mean while the experiment continues and I shall notify you of the results.
