Hi Tyler,
I have a mate south of the river who has done a careful scalp 2 seasons in a row now, and his buffalo looks amazing. You just need to make sure you keep plenty of runners and not go back to bare dirt. I’ve never tried it myself but was always skeptical of scalping buffalo. I wouldn’t use sand either - I believe even most lawn mixes from landscape suppliers are mostly sand, chicken manure, peat, loam and fertiliser. There are a couple of places around like green life soil who do a decent special lawn mix, I’m sure there are others now. This year I’m looking to use as much bentonite clay as I can get down and quality compost after a core aeration. My “soil” is typical Perth sand.
Cheers,
John
