Last month we visited realIPM (www.realipm.com) which is an organization in Thika, Kenya which advocate new methods of growing vegetables. They have developed the use of a 1 meter round, by 1.5 meter high bag made of UV stabilized netting. These are filled with soil and manure.
The plants are then grown in holes around the bag and in the top. This uses very little water .
We are looking at supplying the schools with these bags. It is hoped that the children will find it easier to grow their vegetables using very little water.
