I'm finding that my soil/lawn is going hydrophobic really quickly this season. Could be the heat, but I don't recall it being this obvious this early in the season.
My current choice is adding sugar soap into my humic/kelp/P/K mix and using as a foliar spray the day after a foliar fertilisation application. Waters in well and if I don't add the soap, hydrophobia returns!
Have tried all kinds of wetters in the past like Seasol, Plant Doctor, granular, liquid and I'm finding that sugar soap works just as well...
Cheers,
TC.
