Hmmm, if you play acid rock for them, will they produce better tomatoes for canning?
;-D

Rowan, my world is upside-down from yours, but here in the Willamette Valley of Oregon (Portland, in my case), we sometimes don't get a hard frost till way into the winter.   It's not unusual for roses to continue flowering here through December, and one year I picked my last, red cherry tomato (I think it was a Sweet 100) on Jan. 1. (That's officially about 10 days into "winter" here, but climate-wise it's actually about a month to 6 weeks after our cold winter weather usually starts.) It didn't have a lot of taste -- much like a tomato that's been in the fridge a long time -- but it still had normal tomato texture and was ripe, not rotting.

Thanks for the banana tip, Dianavan.   My mom taught me about putting banana peels around her rose bushes to add potassium (and I think calcium too). I'll have to see what it does for tomato plants.

Of course, my native American ancestors used to put a fish in the hole under a corn plant, and maybe under tomato plants too.   That ought to work well for tomatoes too, I'd think.
