On the finish of the rising season add compost to the soil, which prepares the beds for the following 12 months’s crop of the carrot household.
  • Leguminosae (pea and bean household): All kinds of peas and beans Peas and soybeans repair their very own nitrogen from the air and feed additional into the soil. They make beds for the following 2 years of crops, each of which profit from the infusion of nitrogen.
