It took two seasons. I've got 3 underway with pots of Turface MVP each on long, 2-inch thick branches. I'm not certain how they are doing, but a little poking around leads me to believe I don't have much in the way of roots yet.
Daily average temps are rarely higher than 70F here. Rooting will likely be much faster at your place.
@Eric Group in NC was raving earlier this year about how he was getting roots on generic a.p. in less than 30 days. It takes until August (4+months) to get similar results here.
