I think all urban schools must have a small garden for vegetables and common plants like coffee, tea, sugar cane, so that students know what they use everyday. all planting and taking care of the plants will be done by the students. we can plan their schedules from january to October every year, End of the year is harvesting and garden clearing activities. We can involve PTA (parent teachers association) in the activities. It is big surprise it young generation don't know sugar cane, rice, durian or other local fruits and trees.
