Answer: There are several methods of trying to keep potted plants moist while you are unable to water them. One is to water the plants thoroughly, then fill the bathtub with about an inch of water, set the pots in the tub but prop them up so they sit slightly above the water. Close the shower curtain and shut the bathroom door. This keeps the air around the plants as humid as possible. I would not enclose them completely in plastic as this would prevent air exchange and would probably cause fungal problems as well. Also, two weeks is probably about the longest you can leave them. If possible, you might consider hiring someone to check on and water your plants or offer to swap the favor with a gardening friend when they go on vacation. Good luck with your plants -- and enjoy your travels!
