Back in the Early 1950's before my family moved to Florida, My father seeded our house in cooperation with the neighbors etc. I remember it as quite the project. You have to know many of our new Chemicals and equipment weren't around then. My father seeded in CLOVER with the grass seed, I only assume as a Nitrogen source. Back then everyone just used 6-6-6 on everything. Agriculture will still use Clover in improved pastures. So the quick question is, Does anyone still use Clover in Residential lawns????? I am guessing not because it represents a Broad Leaf Weed.
