Do you fertilize or sidedress with compost? Tomatoes and peppers tend to be heavy feeders. They need a lot of nutrients (but follow package directions if using fertilizer). And I can’t tell from the picture if the soil is mulched. Mulching goes a long way to help prevent soil moisture from evaporating, cooling the roots, and generally helping to limit the impact of extremes in heat and water availability on plants.
We may not have fertilized soon enough. We will see if we can give the peppers a fair shot. Thank you for your help!
Best of luck to you. For what it’s worth, I have a single pepper plant that looks beautiful, puts out a great succession of flowers, and is surrounded by pollinator plants. But it just hasn’t put out a single fruit yet. Oh well. It won’t deter me from planting again next year.
How hot is it where you're at? I have some overwintered peppers that are still full of fruit that set earlier in the season, but pretty much every flower has fallen off for a while now. High heat doesn't reduce flowering much, but it does dramatically stop fruit production.
If you're in the US, I'm in a hardiness zone of 8b/9a though. We have a very long growing season so I know I'll get a fall harvest as well out of both new and old plants.
