Yes, it should be. You can bump up the pot size as needed instead of jumping up to a big one and when its older root prune if needed to maintain a smaller pot size.

Hi Oscar. You can probably go up incrementally in pot size as the plant gets larger, but I tend to 'forget'. I containerize most of my brugs (just seem to have better success in my yard with that) and have been traumatized by the cost of larger containers so I went to talk to one of the local nurserymen I patronize (waaaay too much) and he sold me 2 dz 15 gal black tree pots at $4 ea. It was a big outlay and black isn't exactly showy but for the money I now have lots of matching pots......not to mention not risking someone coming into my yard and stealing nice pots which has happened a couple of times (yep, dumped them and took the $$$ glazed pot!). Anyhow, nurserypots are a thought as your collection increases. Good growing, Will
