We all have our ways & reading text is horrible cause you can't hear chuckles or exchange words as if at a table.
Back to Ca & cow poo, my fear of cow poo (or any smelly ant friendly fert) is fire ants. I've had mounds appear overnight, seen grapefruit tree from seed get covered by so many ants it looked like it was waving at me. My 7gal fruit cocktail planted a few days ago must be sweet cause red friggin ants today were all around trunk, removing soil from roots, climbing up & on leaves. I had to do something so i mixed bifenthrin 1/4 strength or less and sprayed base & trunk.
Ca i'll use sulfate or sheetrock, nitrogen in nitrate i'll avoid, cr90 sulfur i have & will sprinkle some around. Hopefully ants avoid sulfur.
If i hadn't just planted 6 mangos, i imagine if i had tilled rows for trees with amendments that would be optimal, keeping surrounding ground firm for wheelchair.
