Plants in pots
I've had an Acer Palmatum Dissectum for 17+ years, regularly re-potting it in larger pots. It's now in a 21" pot and the Acer is approximately 24" tall. On the face of it the pot should be large enough but it has a very large root ball and is now quite severely root bound. I have tried it in a 24" pot and it looks silly! Can I prune the roots to fit the existing pot, or is it time to plant it in the garden?
