My Bermuda sod was laid in January of this year as a new build. In April it will definitely need aeration. I’ve found twincity sun queen Bermuda seed or turboturf seed. I need sand in some areas for the overseeding as it now has several bare spots that the seed couldn’t root into (Alabama clay) it’s around 8500-9000 sqft that will be aerated and overseeded with maybe 30% that looks like beautiful, full Bermuda. Is any sand okay and should I just spread sand across the entire 9k sqft? Brand, brand new to this and not expecting a miracle but want a healthier/better lawn.
