Earlier this year the college-age son of my Polish neighbors had good luck growing tomatoes and cucumbers under netting.
Peppers grow well in the summertime here in Florida.
With shade during then most blistering hot time of the year, many plants will make it that otherwise won’t.
There’s a you tube guy, The Millennial Gardener, who lives in NC on the coast and deals with heat and vermin and has had good success with shade cloth. He’s got good advice on growing tomatoes and peppers and how to deal with the heat with them.
The other one I like a lot is MIGardener. He lives in the same climate zone as us.
Epic Gardening is good to but he’s in So CA.
