Ah, yes! Total alkalinity . . Just went and did a quick test with my swimming pool test kit, and it's not good, the test strip I used only went up to 720, and the reading was at least that high. <sigh> It might be cost-prohibitive to do what I'm wanting, considering the acidic additives seem to run around $26 per gallon. But I really only irrigate with the well water for about 4 months of the year, in the hot weather in spring and fall.
But I am sure that at least greenhouse growers (of which there are thousands in FL) must address this problem so there is a relatively simple solution. That's where I've directed my quest.
Our soil is basically sand, so slightly on the alkaline side to begin with. Miles from the beach, you dig up shells in your garden here.
Amorphophallus?
Evan! You know what I think about stinky flowers.
A flower's gotta smell nice or it has no place in my garden!
