Q.Will Plastic Bag Coverings Harm My Plants During a Snow Fall?
The plant is a very large indoor potted plant that was outdoors during the summer. We have not been able to bring it indoors yet and we are experiencing unseasonable frost/rain/snow. I placed large plastic trash bags over the leaves/branches but not sure if this is a good thing.

It is best to place a sheet or blanket in between the plant and the plastic. The plastic is actually a very good direct conductor of cold and also traps moisture inside, which increases how well the cold can get in. A sheet or blanket slows the transfer of cold and distributes the moisture more evenly. A plastic bag or sheet should only be used for keeping a cloth sheet or blanket dry.
