I am considering buying the 1.5 gal EZ Flo Fertilizer injector, to lazily feed all my newly planted grass and plants. Their website talks a big game about how well they work (http://ift.tt/2feVsak). Wondering if any of you have any experience? Caveat for me is I am going to have my lawn/garden/vegetable garden all on one the same mainline. Which will mean I will most likely be using an organic sugar or fish product for everything to make sure my vegetables stay organic. The organic cost about 20-30$ more a package, I am also concerned with how well they work on grass vs veggies/plants?
