Work on a Chinese quince

I’ve heard a Chinese quince (Pseudocydonia sinensis) is rather picky to be worked on. As I have one, I’d appreciate to learn about your experience with it if willing to share. What are specifics and oddities of work on this tree, particularly timing of repotting, trimming and wiring/bending but also anything else you’ve found important? Thank you all in advance.

I have a couple in development so my experience is limited even though I have had them for many years (mostly in the ground). I have not had any issues with spring repotting as the buds well. However, I have found that they definitely like a deeper pot - 10 cm vs. 5 cm. Branches of any size are very stiff so I wish I had wired some shape when they were smaller. I am getting some back budding now that they are in the deeper pots, but nothing like a maple. Wounds are slow to heal, but I have been told that use of the high IBA sealers like Kirikuchi-Naoru (Cut Repair Sealer) will help close the wound.

I too would like to hear from folks with more experience with Chinese Quince.

Thank you, Marty. Yes, I’ve also noticed the quince branches are pretty stiff, so I want to wire them ASAP - one of the reason why I started this thread - but still would like to find an optimal timing for it…
BTW, I’ve been also experimenting with using a friction tape underneath of wire for trees with stiff wood (another layer protecting wood of breaking). It looks promising so far - all trees with the tape applied have kept growing quite normally but I haven’t seen how it’s going to be underneath of the tape yet. Have you tried something like that?
