Q.Houseplants
I left my spider and ivy plant in the car by accident overnight and now they are very limp, turning brown and look unhealthy. Can I do anything to save them? I’m even afraid to water them. The soil is not bone dry. The leaves are just hanging over with no life to them. Please help. I live in Mass.
Thank you
Sue

Wait and see is the best approach.
You can trim away any dead and damaged material.
If you see new growth, they can recover.
If the temperatures were low enough and length of time to freeze the roots, they may not recover.
