I have 2 pots of dahlia's (1I have 2 pots of dahlia's (1 tall pink and 1 short red & white) that I have put on my deck for 2years now. In the fall I bring inside and store pot and all in a cool room and only water once a month. The foliage stays nice until about January then dies off. Around March the new foliage starts and end of April I put back on my deck. I live in southern NC and am still getting flowers now mid-Oct.
