Although tea oil websites claim efficacy for earthworm control, a 2007 search of the worldwide scientific literature found no references or data supporting that claim. A single tea seed meal application in early April 2008 reduced castings in replicated plots on the pushup green by more than 95% for at least 5 weeks (Figure 1). In another trial on the pushup green, application of tea seed meal in early October reduced casts by 98% after 2 days, and 83% after 30 days (Figure 2). Finally, a sequence of lab trials confirmed that the chemical basis for tea seed meals activity on earthworms is the natural triterpene saponins found in tea seeds., Early Bird Natural Organic Fertilizer , Representatives of Ocean Organics Corporation (Ann Arbor, Michigan / Waldoboro, Maine), developer and manufacturer of natural fertilizers and bio-rational materials for turf, ornamental horticulture, and specialty agriculture, expressed interest in developing a tea seed meal-based organic fertilizer.
