Very little was known about organic greenhousing then. I needed to improvise. In my market gardening days I found myself to be an almost perfect failure at the repair and maintenance of machinery. I decided that I must eliminate the use of machinery. I fenced in all of the gardens and got animals to do things that machines ordinarily do.
Chickens eat every bug in sight.
The animals go in following the harvest. Large amounts of carbon rich materials like leaves and hay combine with the manure, making the soil rich and sweet smelling. These simple techniques worked wonders. Plant grew like crazy, weeds and bugs were under so much pressure from the activity of the animals that they were very easy to control. Additionally, the animals benefited by the variety given to their diet.
