Title: Kumquat as rootstock?
Post by: Pandan on November 22, 2021, 08:54:58 AM: Hello all!

Basically I'm wondering if kumquat can be used as a rootstock for other citrus types and what problems or benefits could come from that? I can't find a lot of info off google

Froom my limited knowledge poncirus seems to be the go-to for mass compatibility so if compatibility is an issue could PT be can intergraft?

Mostly asking if kumquats could serve as multi-grafted trees partly out of curiosity and also as someone who lives in a colder environment / small living space.

Anyway, because I have a surplus of kumquats and a shortage of flying dragon, I am growing out some fukushu seeds to try this.

Post by: Pandan on November 24, 2021, 11:47:02 PM: So what I'm a little shockingly gathering from these two or three anecdotes are that kumquats are or can be good rootstock but are underutilized? ;D

Marumi in particular is interesting to me given its a manageable size and hardiness, hopefully meiwa would function similarly

Post by: brian on November 25, 2021, 10:47:58 AM: I thought marumi was listed as being not true from seed?

Also, more dwarfing than FD would be a big surprise to me... do you have any links or books you can point me to with more information about this?

I have a fruiting marumi right now I have been eating fruit from for weeks. It appears nearly identical to Fukushu, btw, except that Fukushu has a more pronounced "finger dimple" at the bottom of the fruit, and I've read fukushu is true to seed while marumi is not.
