In recent times, I have only done the basics for my lawn so it’s long overdue some attention. It’s a little bit patchy in places and I have some clover type weeds. I believe my Soil is Sand type and I will get a PH test soon. Could you help advice the order of doing things: Weeds, aerating scarifying and top dressing? Depending on the pH test would I need to include Sulphur etc. into that list?
