Fall planting of petunias was a great idea. The period right after Christmas has always been kind of like a breather for garden gurus as we pause to evaluate plants and ideas that we have put into place in our landscape or perhaps watched other seasoned professionals try.
Back in the fall, I was reading a publication written by my friend Dr. Allen Owings, Professor Emeritus (Horticulture) with Louisiana State University. He was recommending planting petunias as a fall crop in September, October and as late as November in Louisiana. Years ago, I do remember watching them bloom all winter in some city window boxes in Louisville, Miss., which is right on the Zone 7 line. I suppose at the time the supply chain kept me from trying and it slipped my mind.
The Garden Guy decided to give it a try in Midland, Ga., and I am beyond thrilled. Midland is a little northeast of Columbus. Since I am not too far from the hills of Zone 7, I have no doubt they will work in the San Marcos area.
