Whey for Plant Growth?
Q: We make yogurt and strain it down to a half-gallon of Greek yogurt and a half-gallon of whey. We have read that whey can be used to help tomato plants but I’m not sure what that might do to the soil.
A: I don’t think small amounts of unsalted whey applied to a large area would have any bad effects on plants. The protein in the whey will decompose and eventually become plant food. I would not apply it to a concentrated spot because I think raccoons, possums, or dogs might dig up the area.
