What is an organic fertilizer that works for everything?
Fertilizer companies — even those that make organic products — like to make us think we need one fertilizer for tomatoes, another for flowers, another for “vegetables,” another for lawns. But unless you have had a soil test (most of us have not), then there is no way to know what the optimum fertilizer mix is for your soil. So your best best is to use any fertilizer labeled “all purpose” or “for vegetables,” if that is what you are growing. And by the way, you don’t need to buy fertilizer, really. Plain old grass clippings are an excellent fertilizer, and they do double duty as a mulch.
