Hi @katmwall
Looking like a happy and healthy plant. Here is a super soil mix below or check this link for a nice soil mix. Use gloves if you have, and just be careful with moving the root system. You also want to make sure the roots are spread out evenly and not knotted in a ball.
1 part soil: buy high quality soil. The soil must have a spongy texture and vital its free from toxic substances. Dont use your garden soil!
1 part compost: composted rabbit, sheep or goat manure ( I am using cattle as that is what is available )
1 part of 50/50 perlite and coco coir mix.
