I picked up a Live Oak yesterday and plan to repot and root prune this spring.
I have a couple of potted bonsai from a local nursery, but this is the first that I will be doing any major work for.
I have the substrate, soil, fertilizer, ive watched multiple repotting videos and feel comfortable enough to try the process.
The goal of the repot is to get it into a pond basket(the Anderson Flats are a bit too expensive for this stage of the hobby for me), do some minimal root pruning, and to thicken the trunk about 1/2 inch.
What I have not been able to find a lot of information on is when and how much it is safe to prune after the repotting.
The tree is about 8 foot tall, but it will need to be cut down to a point that all of the branches will be pruned to make it bonsai sized. I have read that it is good to wait a year after repotting from the nursery pot before any major pruning.
Should I indeed wait a year to allow the root structure to recover?
Should I do any pruning of the branches at all during that year or is it best to just let the tree do its thing? Will selective pruning help the tree direct its energy to growth of the roots and trunk?
A quick aside - this is an awesome community. Thank you all for being so open, helpful, and welcoming
