I have several plants that are considered annuals here but are perrennials farther south. They are mostly hibiscus, mandevilla, and a kind of butterfly bush but not the buddeleia type. They are all in pots. I was thinking either to over winter them in my unheated garage that has lights, or I could put them into the ground and cover well with mulch and maybe a floating row cover. I really would like to keep them if possible. I also have 2 huge ferns. I was told by the nursery where I got them, to crop them to about 8 inches, divide them into quarters, and re-pot them, then keep them watered and indoors. So, what do ya'll think? Have any of you had any success with this?
