Fukushu kumquat - thornless?
« on: January 14, 2023, 11:04:19 AM »
Looking for some ID help. I'm a bit stumped. Does Fukushu have thorns? My meiwa on C35 doesn't have thorns. I searched Google and this forum and there seem to be plenty of Fukushu pictures without thorns, and some with. My own Fukushu on FD has really large thorns, and I'm wondering if it's actually the failed graft....

Poncirsguy grew his Fukushu stock from seed though, so technically its a Fukushu seedling....

My Marumi has thorns, my Fukushu doesn't.

Sorry, I don't know. When I bought them there was no information about the rootstock.

scamper, if you look at the UCR website (CCPP budwood) it mentions the Fukushu as being thornless. I just purchased some budwood from them and it was thornless.

My Fukushu trees have flowers on thorn less parts of the trees.

Sorry, I have to correct my answer. At more thorough inspection I found some thorns as well.

The thorns on mine are pretty large relative to leaf size. I'm more and more convinced that it wasn't a failed graft, but rather, I was sold a mislabeled plant. The rootstock should be FD, so I would have expected the typical three leaf clusters, which I don't see   on any of the stems.

Your tree does have a lot of thorns, but as long as you get good tasting fruits it doesn't matter.
I've noticed a lot of seedling trees grow thorns more than the parent tree. My seedling pummelo which is a large tree now (18 ft tall) has great tasting fruits, much better tasting than the parent fruit, but it does have plenty of thorns. I cut the thorns off the branches where I will pick the fruits so I don't get stabbed doing it.

You're right in that thorns can be manageable. My main issue is if I even have the right cultivar.

If it's a grafted tree, you should have fruits in 2yrs at least.

Yeah, I have tiny trees on FD from recent graphs producing significant crops already.  They will produce fast
