Yesterday I had some lantana and forsythia in the starter box that looked like they needed transplanting. Well I transplanted about 8 to 4 inch pots. Now I see our weather forecast for the day after tomorrow is light frost and some freeze. What do I need to do to these transplants to protect them from the cold?

I still have about 30 of these new plants in the starter box. What should I do with them for these winter months? I have the starter box on small wheels so I could roll it in and out of the garage as necessary.
