To each their own I suppose. I really feel that in ground plants should be better off, but it's just not the case with me. For some reason I can never get the in ground plants the same as my containers. Possibly it's that I have more control with the containers, or maybe a multitude of factors. Either way, I now stick with what works best for me. No doubt that the in ground experts can blow my container plants away, but I just can't seem to make it happen. One day I'll try a small raised bed - in my mind it's like a mix of both worlds...and see what happens. For now though, it's 5gals all the way.
