Found a 1920s gardening manual at a garage sale that actually works
I picked up this beat-up book called "The Garden Expert" by some old-timer named J.W. Morton for 50 cents last Saturday near Springfield. It had this weird trick for starting seeds in damp coffee grounds mixed with soil, and I tried it on my tomatoes this week. Three days later they sprouted faster than any starter mix I've used before. Has anyone else found an old book with a gardening hack that beat the modern stuff?
