Coffee grounds for Lawn
I've been reading about using UCG's for fertilizing lawns and thinking about switching to it. Main reason is that it is free, the other organics like alfalfa, soybean, etc. I would have to find a feed store or buy it online. I have a few questions.
1.) Can UCG's be the only fertilizer I put down, or do I need to add other organic fertilizers?
2.) I have a front and back lawn which total 2,000sqft. If I were to do 40ibs per 1,000sqft once a month of UCG's, would that be enough?
