This is what I would and I do. I’m not anti-chemical or against synthetics. But organics work better imo. I would spread out Soybean Meal 15-20lbs per 1000sq feet monthly or every other Fed-October. Dry Molasses 15-20lb per 1000sq feet Feb/May/August and Milorganite per package instructions in either June or July. Not only will you have the best looking yard on the block, you’ll have more earthworms than you know what to do with.
