The Q&A Archives: Winterizing Container Plants

Question: Every year I have several container plants that I don't have room to plant in my yard. This year I'd like to keep them until the next warm season if possible! I have a large Hibiscus,a mini rose,licorice vines w/New Guinea Impatients & spikes,Coleus,Strawberry plants,asparagus fern & a small Loosestrife -all in a nice semi-warm place in my garage! I think I can keep the temperature above freezing all winter BUT do I water them?? Do I keep them in sunlight or indirect sunlight??? How do I care for them?? Please reply!! My babies are wilting!!! & ThankS!!!

Answer: Unfortunately the hibiscus, licorice vine, New Guinea impatiens, coleus and asparagus fern are all extremely sensitive to cold and need warm temperatures and bright light all winter. They would be considered houseplants or conservatory plants and will probably die if subjected to the cooler temperatures one would find in an unheated garage in mid winter. The rose, strawberry and loosestrife are winter hardy plants so should manage to survive in an unheated garage. Allow them to slow their growth as the season progresses and keep the soil just barely moist. The danger is that the roots or stems will rot if kept too moist, yet the plants should not dry out completely.
