Rooting sweet potato vines to overwinter
Recent posts on rooting other annuals to take indoors have me hopingÂ
I have been growing sweet potato vines for several years. A few are in mixed deck planters I take in and out every year (though those donÂt always make it over the winter and have to be replaced). But I also plant 6 or more in other planters and in the garden. This year I was dismayed at how costly they were at the nursery. I still shelled out but bought fewer. I tried taking cuttings last year but they died immediately. I noticed that the cut stems ooze a milky liquid. If I have to I will dig up the whole plant but IÂm hoping that will not be necessary: plus I am likely to leave it too late before frost.
The chartreuse colored ones in particular I really want to keep going. WhatÂs the secret for these?
