I purchased recently Juglans nigra and potted it temporary because I have not yet prepared the ground for it.
The tree was delivered bare rooted and its just over 2m long.
I potted it into a large pot 1/2m diameter and 2.5 feet deep pot and added some root growing fungi , mixed normal soil with some neutral humus and a bit of gravel to help the drainage.
I intend to keep it in this pot until the autumn by which time I hope to be able to prepare the permanant spot for it.
Did I do right please?
