I have been given a 10 year old pot grown magnolia. What is the best way to plant it in the garden? Do the roots need teasing out, and if so, what is the best way to do this? I am a bit concerned in case it is pot bound. I haven't looked yet as it is so heavy. When would be the best time to plant it? Any information would be greatly appreciated.
Thank you, Mel

Magnolia planting is best done in spring or fall in a moist, rich, slightly acidic soil that is amended with compost or leaf mold. Since it has been in a pot for some time, you may need to root prune it prior to planting. Here is more information: https://www.gardeningknowhow.com/houseplants/hpgen/prune-roots.htm
