Tea seed meal is a 100% organic fertilizer, which is the residue from camellia seeds after extraction. the active ingredient is tea saponin. Heavy concentrations of saponin works well in expelling earthworms, cutworms, slugs and help shrimp/crab grow by killing unwanted fishes. as a result, tea seed meal can be widely used in golf courses, sports field, backyard gardens, rice field, shrimp/crab ponds and so on. however, people in Japan like to purchase it to improve the soil quality as well due to its high content of organic matter.
