I live in the Avon area of Mass. Is it too late to overseed ? I'm using Jonathan Green seeds, A mixture of dense shade and Black Beauty Ultra. I've aerated, and detached but I'm afraid I'm too late to drop 100 lbs. of seeds down, and waste the good seeds. I'm looking at 14,000 square feet of grass to be over seeded. Am I using too little or should I apply more seed?I believe the bags of seeds uses low estimates when overseeding, I like to give it as much as possible< What do you think , Time and amounts??
