After years of disappointing harvests filled with small, wireworm-ridden potatoes, one gardener decided to try a radical new approach last season. Dubbed the “Thai method” by skeptical neighbors, the technique involves adding a surprising ingredient to each planting hole: small, cheap fish like smelt or sprat. The results were nothing short of astonishing. From just two hundredths of a hectare (approximately 200 square meters), the gardener harvested a whopping 8 tons of large, smooth, and delicious potatoes—nearly double his usual yield. The science is simple: as the fish decomposes, it releases a slow, steady stream of essential nutrients—nitrogen, phosphorus, potassium, and calcium—that feed the plants all season long, far more effectively than quick-to-wash-away mineral fertilizers.
While the method proved incredibly effective, it came with an unexpected challenge: a neighborhood cat invasion. The scent of fresh fish turned the potato patch into a feline magnet, leading to damaged plantings. However, a solution was found in fish meal, a concentrated, odorless organic fertilizer. Used on the rest of the plot, it delivered the same remarkable results without attracting any animals. Combined with a thick layer of straw mulch that conserved moisture and suppressed weeds, the fish meal created ideal growing conditions. The gardener now swears by fish meal for its ease of use and zero odor, recommending that others mix a tablespoon into each planting hole and mulch generously to achieve their own record-breaking harvest.
