Overwintering Gaura in pots
I've just bought three Gaura plants that I plan to plant out in spring. I bought them now as they were going cheap! The roots were growing out the bottom a little so I've potted them on in slightly larger containers.
I'm planning on overwintering them in our brick built wash house so they'll be protected from frosts, but wasn't sure about watering. I previously lost one I had grown from a cutting and I'm not sure if I over or under watered it.
How much/little water should I give them do you think?
Thank you in advance,
