I am redoing the landscaping left by the previous owners of my house. When going to nurseries I find that everything comes planted in a pot. When thinking lazily about it, at one time I considered just putting the pots in the ground as is, but as I thought about it, it seems to make more sense.
The problem with my landscaping is that most of the bushes have overgrown their plantings. Keeping the plant in a pot would stunt their growth. Also keeping plants in their pots would make removing them easier in the future if I wanted to, say when we lose our love of grasses or box shrubs. The only down side I see is that I would have to dig a much larger hole to put a retainer in and make sure that it was well drained so the pot could be used.
What are the pros and cons of planting directly in the ground vs burying the pots when placing the plants?
