Some people feel differently, but I reuse my potting mix. For me, it's too expensive to toss out. I "fluff" it by digging deep in the mix with my trowel and turning the mixture over and over throughout the pot. I don't worry about amending the "soil" because I water weekly with a low dose of fertilizer. Good luck whatever you decide to do. Gardening is always a bit of an experiment.

It's been very hot here, too, but I'm going to plant some fresh kale and lettuce this week. Let's hope we get great fall harvests.

If you are reusing peat based mix, might be worth mixing in some pine bark to air it up. Bark is cheap. Peat is already too water rententive, and gets worse with reuse. You need some air in the soil.

By the way, peas and kale will often recover with new growth once the weather cools. They are cool weather plants. You may not need to replant. Kale will even survive well into frost, and I've had it come up again in spring before. I'm just east of you and my snow peas are starting to regrow and produce new peas after mostly dying off in the heat of summer.

Thanks for the tips. Yes, I can probably get my hands on some more bark/mulch.
Turns out the romas aren't going to be yanked out just yet. They finally have a few fruit on them that haven't been attacked by BER yet.
Instead, I plan to take out the eggplant plants that never grew much, and use the big 18gal container they're in.
My broccoli spouted, but need a few weeks before they're ready to go in the garden, I think.
I pulled up my peas (they were very very dead), but the kale is still puttering away, and maybe will start growing a bit more. Beans are still going.
I'll let you know how it goes. Thanks!

I thought my peas were dead too until I saw the beginnings of new growth, so I left them and are now starting produce pods again. Not saying that's true in your case, but don't be too quick to give up.

Next year, try the 5-1-1. I've never had BER in it. You won't regret it.
