Sorry to hear about your poor plants.
I wish I could offer some positive advice.
About your house plants dying, I think all that rain is a shock to them. If you still have any left alive, I would suggest taking them back inside until after the strong rains stop.
But I hope your other plants will make it through and recover, once the rain stops.
Thank you for your kind words and advice. Yeah, the houseplants that went outdoors died so suddenly we couldn't save some of them. Luckily we hadn't moved everything, so some are still inside and doing fine.
> "...once the rain stops..."
I'll hold that thought dearly and pray.
