How to keep potted 4 o’clock plants alive in winter

Question

I waited too late to plant the seeds so I put them in big pots.

Answer 1

Allow the pots to go dormant naturally.
You will want to periodically add some moisture to the pots so the roots do not totally dry out.

You can add a layer of mulch to the top of the pot to help with moisture evaporation.
