Question
I live in NYC and have 7 or 8 large pots and window boxes on the roof outside.  I put in all new dirt last year mixed with some peat.  I will be planting morning glories, impatiens and other easy to car for plants again this year.  Should I add anything to the soil again before I reuse it this year?  Thanks.  Joe

Answer
i'd empty the old dirt from the pots and mix new soil w/the old dirt before refilling the pots. use a good indoor potting mix like jungle growth, peters, miracle grow, etc. visit a local garden center to find someone knowledgeable on container plants. quiz them on soils & fertilizers. buy some granular slow release fertilizer(i like espoma brand products like plantone) while there.
good luck
