Organic lawn food comes from animal, plant or mineral sources. It does not contain any manmade chemically formulated additives. Some organic products claim to be organically-based or natural-based, but they contain manmade chemicals or nutrients and pesticides. Check the product label carefully for any chemical derivatives.
Organic lawn food is made from livestock waste, municipal waste, bone meal, dried blood, manures, vegetable meals, feather meal, fish scraps and crushed minerals.
Grass seedlings are fed about three weeks after they have emerged. A healthy lawn needs feeding every four to six weeks during the growing season.
Most organic lawn food contains 3 to 10 percent nitrogen that is slow to release into the environment. It may take several weeks or even months to become available to the grass.
Grass responds slower to organic fertilizers than others types of fertilizers, which means that it is slower to take effect in the spring and can extend grass growth in the fall.
Do not apply high amounts of nitrogen-rich organic food to cool-season grass in the late spring and summer or to warm-season grass in the fall or winter. Applying during these times increases a lawn's susceptibility to pests and environmental stress.
Applying organic lawn food year-round does not help grass growth. Grass does not take up nutrients while it is dormant, so the weeds are able to absorb the food.
