I Am Seeding A New Lawn In September,should I Clear It Of Newly Growing Weeds With Chemical Spray Now

Question

It’s quite a large area and I’ve hand cleared it 3 times already but they keep on coming up.

Answer 1

Yes, I would start to spray so that it will, at least, be more manageable for your new grass to emerge. Products containing the chemical, Glyphosate, are fast acting (within a week) and breaks down on contact with soil through a process called microbial degradation.
