Leftover coffee as nitrogen fertilizer?
This is related to another post I made. My soil pH is in the 7.0-7.5 range- just within the range for the leafy greens and whatnot I am growing for winter, but room to be more acid. I also have a major lack of nitrogen, based on soil testing and lack of growth of everything but the peas.
Would it be a bad idea to save my leftover coffee and water my plants with it, perhaps if I dilute it 5-1 with water? As I said, my soil becoming more acidic doesn't look to be a problem
