Kinzu (Golden Bean kumquat)

[bonhe]

I grafted Kinzu on Troyer citrange rootstock in 2013. At this time, it is bearing the flower buds. I'll let you know its history. The Kinzu scion was given to me from my bonsai teacher, Richard Ota, who got scion from Mr. Ohara 3 years ago. Mr. Ohara obtained a kinzu tree from UCR years ago. http://www.citrusvariety.ucr.edu/citrus/hongkong.html






The fruits were from my teacher's kinzu.

Nice results Also looks like that graft joint will be easy to clean up and not be noticed in the future. Do you need other trees to pollinate that or will it fruit as is

I've thought about using citrus for bonsai at one point. They're just so darn susceptible to disease, pests, and die back it makes me hesitant. Another small fruiting one is the calamondin orange. The graft that small will blend in a short time.

Thanks. It does not need other trees to pollinate.

My area is famous for citrus growth.
Next time, I will make a graft much lower than this.

In my area, citrus have to be indoors for the winter. I love them, and your graft is excellent.

The exceptionally small fruit of your cultivar make it especially nice for bonsai.

The tree is in flowering few weeks ago.


and the fruits at this time. The color of small one is almost black!



the bigger one.

Hi Bonhe, your plant maybe chlorotic. See the few yellowing leaves?

I am not so sure about it Si. The new leaves have dark green color. The old leaves have yellow parts which I think due to the site I placed this tree last year! I have been trying to find the best location for this tree for 2 years, and now I think I got it right! ;-)

The fruits are not ripe yet.

It was this afternoon.
You can see its bright orange color and its craterlike surface!

Coming along nicely, I love flowering and fruiting trees.

This tree is bearing lot of fruit as this morning.


Ready for another grafting next year.
Below are 2 trees to which I grafted Kinzu on this year. They already bear few fruits!!

You should actually plant these into large containers rather than grafting them to trunks. Kinzu is notoriously slow growing. So slow, that the roots thicken faster than the trunk. They easily propagate from the roots though. Min Hsuan Lo has a good blog post on creating Fortunella hindsii. Another good idea is to graft the scions to branches and use the trunk of other citrus. It will take a lifetime to grow a kinzu trunk.

Looks like a fun tree Bonhe! I have a small one that is growing it's first fruit.

@carp , do you have a link to the blog post?

I'm currently working, not hard obviously, so you'll have to search his blog. I recommend using a browser than can translate pages automatically because its all in Chinese.

You are correct. Kinzu grows very slow on its own rootage but when it was grafted on rootstock such as Troyer citrange, it will grow really fast! I used Troyer citrange as rootstock. In one year, the new shoot can grow about 3 feet!
