Post-Yamadori Care
Excerpts from ry2tree2
General Protocol for Yamadori Aftercare
Pot the plant into a container it fits into as quickly as possible after the dig (within a couple days max). Minimizing this time minimizes stress and maximizes healing. Some extra root pruning may be done but not too much or it may not survive. Fine roots must be left on the tree when potting as they are the engine of your tree's survival! Honeysuckle won't be picky, use any potting soil you have available, but bonsai soil is preferred when you get more advanced or for older trees and more delicate species which are challenging to transplant.
This part can get nuanced for advanced practitioners. I'll just leave you with the idea that 100% pumice is the preferred bonsai soil to surround freshly dug rootballs as this allows lots of air into the pot and promotes lots of fine root development. Perlite is allegedly comparable, cheaper, and more widely available but my own experiments with this are underway so I cannot say yet. Try for yourself and let me know!
Large trees can be put into custom-built wooden pots. You could also leave them in the black contractor bag if you used the durable kind and poke holes throughout for water and air to get in and out of the rootball. I have done this with success, but I can't say that it is better or worse. I'm still collecting data on this method but it is VERY convenient (on time and cost), and my teacher Dan Robinson has used this method with success for years.
Leave the plant in the shade while it recovers from the dig for at least the first summer due to the stress of heat and water loss. Do not fertilize for the first few months after digging either as excess ions from fertilizer can dry out sensitive new roots and kill the tree's recovery. Water regularly. Keep the soil moist but not soaking wet.
Water regularly and fertilize lightly throughout the summer. [Most] species recover much more slowly. Survival is only assured after 1 year. Do not prune unless you are confident in its survival.
In winter, insulate your roots from and protect them from dry winter wind. This is the same recommendation as most bonsai, but especially true for sensitive freshly dug plants! You will still need to keep the soil moist as it can dry out even in winter.
Mist a lot, water sparingly
Sweating is not recommended for conifers, but a long list of sensitive trees to force budding and rooting.
Bonsai nut blog advice re Collecting Coastal Redwoods
They do not like to dry out. They are coastal trees and are accustomed to daily mists. Also, being on the west coast they are do better in morning shade and strong afternoon sun.

A fellow PNW nutter here....way up north on the 50 th, been collecting shore pines in bogs and rocky areas. Most of us do not remove any of the original soil immediately after collection......some of us wrap the root ball in the easily accessible sphagnum moss and leave it wrapped like that for two years, some put into grow pots and others place the rootball on top of pumice/Seasoil mix (landscape cloth covering ground) then cover the top with same mix.....all treatments have great results
