Based on this video, one of the most difficult issues with growing an urban garden is actually starting. For the sunny, hot climate in Thailand, providing enough water for the plants will be one of the trickier aspects of caring for the plants. The plants which are recommended are pak boong and basil as being hardy plants for beginners. If you have a concrete slab and no place to grow your vegetables, coconut husks can be used to provide a layer of insulation before putting some soil over. The coconut husks help to maintain the moisture in the soil and helps keeps the plants cooler throughout the day. Manure is added to fertilize the soil instead of using chemical fertilizers.
