I have about 30-40 containers on my deck and I never change out the soil..I plant summer flowers in the late spring and pansies in Oct. All I do is rip out the old rootballs, turn the soil some, take out some soil to make room for the new plants, add some slow release fert and plant the new flowers and mulch on top. I don;t even know how long the soil has been in the containers....maybe 6 years?? maybe longer for some. The soil that I take out to make room for the new plants I always put in a new container that I have just bought.

As long as you are adding a fert that is complete ( all the micro nutrients as well as NPK ) and the soil hasn't had a fungus in it, the plants should do fine. Here are some of the containers-how they look right now
