Today i sprayed copper on mature Kent. It has anthracnose here & there, always did & likely will.
If i get a couple dozen delicious mangos from it, i'll be satisfied after just 1 last yr.
Looks better then last yr, i fetilized better, foliar fed once or twice, spread some gypsum, sulfur, iron drenched once.
I've been watering it almost daily for 2 weeks cause i tossed some fert on it then.
I know watering isn't suggested, and cold spells needed, but i see quite a few spikes popping out & buds forming quite nicely. I even used a toothbrush to clean black off buds i can reach 2 days ago lol.
Experiment, we shall see.
