原文:
Coffee grounds have recently become a common soil amendment, especially since Starbucks launched its free coffee grounds recycling program. Coffee grounds applied to the soil will benefit blueberries by lowering soil pH slightly, adding nutrients and improving soil texture. But don't overdo it, and avoid coffee grounds if you already have acidic soil. The coffee grounds may lower the soil pH too much
