What should I do with monster junipers potted way too deep?

[Brain Treez]

Last weekend I picked up two junipers in 7 gallon cans from a wholesale nursery for cheap. They're definitely the biggest material I've ever had, with great trunks. They weren't labeled, but they sure look like chinensis Old Golds. The problem is they're potted way, way too deep. Considering the time of year, it seems too late to repot them.

You can see from the photos that there are several branches coming up from soil level or below. I'm guessing they've been potted like this for more than a year, because the surface soil is very dense. (Photos are all from one tree, the other is similar). Are they going to be fine until early next spring to repot then? What do I do?

Too late to repot this year. Water and fertilize carefully this year and repot next spring is what I would do.

Don’t see why not. It’s been fine so far?,

It’s entirely possible these branches might have rooted too

This is a great time to clean up the detritus develop a basic design, kill off some branches and created Shari.

I can't really make any decisions around design until I can see what kind of trunk is actually down there. So I feel stuck.

Hmm…

Ok, let’s hove get unstuck.

First clean up the branches and trunk.

Next dig gently down around the trunk to uncover the entire nebari.

Then Tilt, tip, mark branches, take photos and design plan to your hearts content.

Cover it up …or not. Shouldn’t bother the juniper one iota

It’s done all the time

The trees will be fine until next repotting opportunity.

Junipers I've worked with are very quick to produce new roots on any part of trunk or branch under soil level. Sometimes mine even start roots above soil level if humidity is high. This means there's a very high likelihood of roots all along the buried trunk. If they have not been buried long those roots might still be thin and can be cut easily. Unfortunately roots feeding the trunk also contribute to thickening so I've found inverse taper very, very common where new roots have been growing for more than a few months.

No problem digging down along the trunk to check what's happened. Any tree can cope with the loss of up to around 10% of roots at any time so cutting a few small roots while you investigate won't hurt. Given I can see lots of matted roots on the soil surface I'd say digging down to investigate the roots will be difficult and probably futile anyway.

I can see from the final photo that the tree already has reasonably strong surface roots growing from the trunk. That will almost certainly mean inverse taper below so I would be working on a plan for the trees as they are now. That could mean splitting the extra trunks growing from the soil off as separate trees or designing multi trunks. It is almost certain that each trunk will already have self layered below soil level and have plenty of roots to be able to survive transplant as a separate tree.

One thing I typically do is pop the whole thing out of the nursery can and clean top down until I find the root spread. Then cut the rim of the pot down using tin snips and plop it back in. Gets you to the root flare but doesn't disturb the roots enough to harm the tree. Just don't remove too much foliage before the first repot because if it can't use up the water in the rootzone then the roots can rot.
