The Clorox tip wasn't mine. Sounds interesting though. I use an Epson salt spray in the evening. It contains magnesium sulfate, which helps with cell wall structure. Bell pepper and tomato plants do well and turn really green.
I do know that too much chlorine in city water is detrimental to the organisms in the soil which breakdown minerals to nutrient forms which plants can use. If you use chlorinated city water for watering, let it sit in a barrel or bucket of a few days - the chlorine will dissipate. PH of the water is very important too. You can get a test kit to check it.
Our city water is very alkaline, so I use rain water and even set up a reverse osmosis unit for watering my box garden.
The clorox tip was mine.
In the deep south there’s a microb-a-palooza in the summer. All with the goal of melting your tomato plants into piles of black goo.
The clorox stuff stops them :)
The copper stuff you buy at the store might actually work in less humid places. Here you can almost hear the blight laughing at you.
I got worried they’d eventually mine my property for the copper I’d sprayed on my tomatoes over the years LOL.
Thanks for the tip. I have city water for the house, a well for irrigation and also on septic. Our water Bill’s even with 3 girls in the house averages about 20 dollars per month. That’s even with teenage girls who seem to only take “hollywood showers”.
