Not every gardening tip comes from a bag of fertilizerJust when you thought you had heard it allGrowing up in New England, we relied on the Old Farmer’s Almanac for planting tips, weather forecasts and some fun reading quips and gardening wisdom. Over the years, I’ve collected a few unusual gardening tricks of my own. Bury a small, low-cut tin can level with the ground and fill with cheap beer (save the good stuff for yourself). Fish heads: Yes, these smelly things have lots of nutrients, especially phosphorous, and make an excellent fertilizer. Bury used tea bags in the soil for an excellent natural fertilizer, soil conditioner and pest deterrent.
