Over-wintering Brugmansia, Lantana & Coleus
I live between zones 5 and 6 outside of St. Louis, MO. I have several brugmansias that I want to try to save over the winter. I know you can bring them indoors over winter to go dormant, but I would like to know the correct steps to be successful.
1) Do I dig up the plant (which is currently planted in the ground) and pot it and stick it in the basement?
2) I want it to go dormant; so I expect it to lose its leaves.
3) Does it need any sunlight while it is dormant?
4) How often does it need to be watered?
In terms of the lantana, how do I get this plant to go dormant? For the coleus, I will dig them up and pot them as houseplants and keep in a sunny window over the winter. I will probably also take some cuttings to hedge my chances.
Any other thoughts or feedback from anyone?
