| last year I kept a petunia plant alive in our attached garbage by keeping it moist, but can I also keep petunias in my basement under plant lights? in other words, must they go semi-dormant? Pat |

| I'm not sure what you mean by "semi-dormant ", but petunias are true tender perennials and can be overwintered quite easily. I recommend that you trim the plants back before bringing them inside and keep the basement quite cool. You might prepare the trimmings as cuttings and try to root them in a porous potting medium. This is not the ideal time of year for rooting cuttings, but petunias are pretty cooperative. Eash stem should be prepared properly to insure success.

| I wouldn't bother keeping the lights on for the petunias - buying new plants or seed will cost you less than the cost of electricity. If you're running the lights for other reasons/plants, it wouldn't hurt to try, but I don't think it's very smart in terms of $$$ to do it just for the petunias. |
