This tree needs a dormancy period...So, I'm not familiar with climate of where it came...How far different in climates you are...Thinking couldn't have been far off. For they are assuming zone friendly in both places.

What was your reasoning to stimulate spring...verses allow it to go dormant? I know...the red chojubai are a finicky species even in the right climate. Wish I had more to offer...just trying to understand the reasoning first and foremost, the reason you didn't want to allow for dormancy?

Also...what sun is this getting? Morning or afternoon? For I was told not to allow them afternoon sun it's to hot.

I think this one has passed the point of return from the death. It has been declining for the last couple months. As I mentioned in other post, you know if the tree going to die weeks before it actually die. Maybe an emergency repot? If you have to try to stimulate Spring/Winter for it then it fail sooner or later

What I did last saturday was to move it into a bigger pot with medium pumice in the botton and on the sides of the original root mass.. roots were ok in my opinion.

I see it declining too.. 2 weeks ago I thought it was recovering, leaves stopped turning yellow and falling off and new leaves were emerging.. I finally thought i was doing ok, then.. leaves started to dry and fall.. I think i prefer the yellowing!

Stop messing with it! :)

Yellowing inner leaves are old leaves generally dropping from no longer being necessary. (The tree is finding the newer leaves are providing a better return—energy input—on effort expended.)

The brown leaves on June 13 look to me like minor light burn.

Is it indoors? The light colored, wrinkly leaves look like sign of poor environmental conditions. These trees like air flow and handle chilly weather (10–20ºC) just fine.

Quince are very finicky trees. If you leave it alone and give it the right watering, soak then let dry a touch between watering, it may grow new leaves. But you have to leave it be for now to see if it can recover.

Chojubai love to pout and lose their leaves when disturbed, they generally dislike repotting as well, put it in the shade, keep it damp, not wet and leave it be. They often recover when least expected. Key is to leave it alone, it has had enough stress.

Update: this is the tree now:

unnamed.jpgunnamed-2.jpgunnamed-3.jpgunnamed-4.jpgunnamed-5.jpgunnamed-6.jpg

But we are really hitting winter here, having lows of 35 ºF (2ºC) (My JWPs like that! haha) so I don't expect it to grow much more...

Btw, do you (or know who) sell chojubai rooted cuttings or bonsai/pre-bonsai in the US? Im travelling there next week.

That would depend on where in the USA you will be visiting? If you are in the Pacific Northwest, i would suggest Bonsai Northwest as a source! You have to ask, the smaller rooted cuttings are usually in a less visible area behind the main display greenhouse;)

Thanks! Well, I'll be in Sunnyvale (CA) and Santa Monica (CA), they are in Seattle.. do you know if they ship trees?
In that case check with Lone Pine Gardens ( Sebstapol ) or Brent at Evergreen they are both in California. Easy to find on the internet. Others on this forum from California can probably add quite a few more suggestions.

I was at Lone Pine Gardens two weeks ago, and they had four red chojubai rooted cuttings in 2 inch pots. When I left, they only had three :). They also had a pretty large selection of other quince cultivars in both two and four inch pots. I doubt they ship trees, but I guess it wouldn’t hurt to ask.

It’s a wonderful nursery to visit. The nursery covers 3 acres (I believe), they have quality material, and the people there are very knowledgeable and helpful.
