I suspect something to do with soil and roots. I just lost a Chinese quince a of a sudden. I've also lost some flowering quince looking the same way.

Geez, I hope you don't lose that tree, was such a nice pairing with the pot.

A wipe down with 70% or 90% rubbing alcohol (isopropanol) will effectively kill most bacteria, molds, fungi and to some extent virus. 70% works as well as 90%, less than 70% does not work as well.

Something I learned from lab people while learning about tissue culture is that 70% is actually far better for disinfecting than 90%. Seems counter-intuitive I know but apparently, that's the way it is.

Weird...okay...diluting with water I presume.
Wow so sorry to hear this... It's always a kick in the teeth to lose one and not quite know what went wrong.
Thanks Clyde...I will forever feel partially responsible. I ponder if I should have repotted this season. It is what it is. I had hoped at onset to keep lower section. But don't see that wise...it most likely will succumb to it anyways.

The reason 70% is better is the fact that it evaporates at a slower rate than 90%. Therefore it has a longer contact time with any possible pathogens.

I did not see the pictures until after I sent the PM. Doesn't really change my response. But it does look bad. As soon as it is safe to put outside, set it a good distance away from your ''good trees''.

It does look like the rot ran down to the roots.

If it dies, take it out of the pot and see if it is the ''circling root'', I am skeptical that this would be the problem, a visual check can confirm or debunk the ''circling root'' idea. I really doubt that this sudden death was circling root related.

Thanks for the indepth information. I really don't see it as a strangle root myself once tearing off branch upper area was not marred. It all came from lower in the tree.

Will see what if anything if they can test it at the nursery. They have that Ohio state degree guy that did that treatment on my landscape tree.

Will hold off on pitching it...until it dies...and then look in the soil.

Sorry to see this, but it happens to everyone now and then.
Thanks Judy...this one I had created from nursery stock as you know. Its the one my son also was liked.(neither really interested in the hobby) He hugged me last night and told me he was really sorry I was loosing the tree. Compassion from him helped go a long way. It does happen as you say...this is at least less of a loss for investment at least in $$. Only upside...will clear a space for better material. I do like quince...they bloom so beautifully. I may still peak in nurseries at their stock...from time to time.

Cut it out, Darlene. Cut it back to clean wood. Then seal with it with cute paste. You can worry about aesthetics later.

Leo's observation about water molds caused me to do further googling and reading. I think I now know how I lost my Natal plum last summer.
