*jaku, I make my own liquid fertilizer for the grass. Started it with just pulled weeds, put those in a bin and covered them with water. Over time I added dried grass clippings, coffee grounds, free from Starbucks and a lot of tea from tea bags, dark molasses and really cheap beer, a little seaweed, epsom salts, potassium, a few older vitamins and a little finished compost and of course, chicken poo!! ONLY PROBLEM; that 1 bin full is enough to provide for about 6O blocks worth of lawns, I think!! My grass and greenery love the stuff, but I only need to filter off about 1/2 a cup to a cup a month to make a 2-liter of liquid for a hose-end sprayer. I WATER FIRST then, take a 1/2 cup filtered bin mix, add a cup of Murphy's oil soap and water to fill the 2-liter, put that on the sprayer and can do the whole lawn over twice if need be!!!
