Commercial yard fertilizers contain harsh chemicals that are dangerous to pets and humans. Fortunately, there are alternatives to using store-bought fertilizers for getting a yard full of lush green grass. Coffee, for example, makes an excellent homemade yard fertilizer. It is enriched with nitrogen and potassium, which are essential nutrients for any healthy yard. You can either save your used coffee grounds, or offer to take them off the hands of a coffee shop owner.
Lay out a few metal sheets and line them with a sheet or two of newspaper.
Spread your leftover coffee grounds evenly over the newspaper sheets. According to HGTV's Paul James, you shouldn't allow your coffee grounds to get any higher than 1/4 inch thick.
Set your trays of coffee grinds aside to dry out. This may take between 24 to 48 hours.
Sprinkle the dried coffee grounds over the soil in your yard. You should begin to see results in two to three weeks.
