Taking in account all the marvellous natural resources in tropical environments, we have started a pilot project growing more than 30 crops (vegetables and fruits) applying Good Horticultural Practices from Seed to the Plate for the Consumers in Tonga. The initial commercial plot corresponds with 2000 m2 is located in Vaikeli at Fonongahina Road between Liku and Loto Road, Tongatapu island of Tonga. There will be consecutive sowing dates to reach a constant quantity, quality and diversity of organic and fresh vegetables and fruits all year round. Everybody involved in this pilot project was advised to take the following:
