The base on this side is sick! Is this a San Jose?

Well here it is. I put it in 100% pumice. Is there anything else I can do to increase success? Fertilizer? Etc.???

Full sun. I’m not sure if you’re meaning to keep that “humidity tray”…. or just for the photo

Full sun is difficult. Very wooded here. I was hoping to keep it moist all day with the try, while I am at work 10 hours a day. Is it a bad idea?

 

[Nor Cal AC]

Yep, replant it in straight pumice. Do it now and it won’t hurt anything. Build a small wood box (no colendars) that is just large enough to accommodate roots, and no extra room at all…and wire it in tight so it can’t move. It will not make it in the current soil/bucket arrangement.

Water sparingly, but mist the trunk and foliage as often as you can…multiple times per day. Don’t let it get too much sun.

Keep taking photos every week to monitor change.

If interior foliage yellows, it’s a good sign, if all foliage changes color gradually, it’s a bad sign. You’ll know if a few weeks if it’s survived the initial shock. Don’t expect any growth until spring.

Nice trunk, good luck.

Re-potted in pumice today. There wasn't enough roots to fill the pot. Probably 40%. Is that ok?

Any help identifying the exact variety of juniper this is? I want to know if people ask.

As much sun as you can give it would be great. I was advised by well-known collectors that the reason why you re-pot it in pure pumice and let it recover with that substrate is that it has excellent aeration, water absorption, and fast draining properties. So keeping it on a humidity tray somewhat defeats that purpose. Also, it might encourage root rot. To let the roots recover, develop (ramify), it’s a fun game of cat and mouse when it comes to oxygen as water balance.

I’ll post a photo of my collected material tomorrow (daytime) for comparison.

Personally I wouldn't let it sit in a water tray. I let my collected RMJ slightly dry out before watering it.

This is the critical advice! I worked with lots of people who brought in yamadori junipers from the California desert and mountains. The roots are impaired, so you have to slow down the rate of transpiration from the tree while not overwatering the roots. This includes:

(1) Misting the foliage
(2) Protecting from wind or building a humidity tent
(3) Bright indirect light, but no direct sun
(4) Do not overwater the roots! In fact, be careful when you mist the foliage that water does not drip into the soil and saturate the soil - particularly if you are using misters set on a timer. Consider tenting the soil loosely with plastic (don't make it air-tight because you still need air to circulate) so that excess rain or sprinkler water runs off. This way the soil is only watered when you decide it needs it.

I planted in straight pumice, as per suggestions, and this is the result as of January 28th 2022. No Sub-Zero Temps. Watered adequately, dying. Any suggestions?

I still see green that it's pushing out... so don't give up on it yet. Can I see the substrate and the container? Did you take out that humidity tray?

 

[Kodama]

Aw man...sorry to hear but hopefully not too late.
What are your thoughts as to why that might be happening?
Tree might be working out the chopped roots? Could one of the chopped roots belong to that branch?
Wondering if a clear bag with a few small holes over the foliage to help retain humidity?
It needs a hospital

It is in a 2 gallon black pot in 100% pumice. I feel like I should have left it in its native soil. I took it out of the humidity tray. This picture is two weeks old. It is much more crispy now.

I might try the bag. The foliage is very very dry.

 

[Nor Cal AC]

I work all day, so keeping the foliage moist all day is not in the cards.

Don’t change anything. It has green growing tips to work with, and it will shed some foliage along the way. Bagging the foliage is a really bad idea.
