Do you have a picture of a large prague citsuma plant?

I have a prague but it is not very big, I don't think it will get much bigger though.

It seems to be in a decent shape. I though it grows in a really ugly way but it looks just like a poncirus tree
Damn I really wanna plant a bunch of these and wait a decade to have my cold hardy citrus orchard lol

[vnomonee]

if you can get taitri, which is hardy in zone 7, use that as a rootstock and you won't have to wait decades. I have a graft on taitri outdoors which has outgrown the original prague I bought from Stan that is on poncirus (2-3 years ago) in just a season.

Here are my two. Not very large but not small anymore either. Grafting on a vigorous rootstock helps a lot. It is kind of half-deciduous but even in summer only holds few leaves. One of the uglier citrus in my opinion .



I grafted this one on a strong, thick Poncirus at around 90 cm. In spring, it sends out shoots that can exceed 20 cm.

Here's my medium Prague; it's about 6 feet tall. Defoliated from the recent harsh winter, but undamaged and budding out nicely now. View from the dark side:

Has anyone tried rooting cuttings or marcotting? Wonder how vigorous it would be on its own roots.

I grafted four scions of Prague on different rootstocks in my greenhouse in Feb 2023 and all four failed to bud out all year despite staying green. I cut one off thinking it had failed, but the other three are still just sitting there now, green but refusing to bud out. I've never seen anything like it, but I assume it's related to the lack of vigor, or incompatibility with rootstocks (3 were different kinds of mandarins, one was a lemon seedling).

I noticed today that one of the three is showing very slight bud development, so I'm holding out hope. That's the one that's grafted to the central leader of a grafted Pixie mandarin (in the ground in my greenhouse).

@vnomonee

how do you hold of those? sounds interesting, but im barely getting results on google

[lajos93]

@jim VH

wow how old is that, 10 years?
how high was is grafted?

i heard its better to graft it high around 1 meter

[vnomonee]

Maybe you can find some seeds or cuttings on the forum. I don't have fruit yet but when I do I will share the seeds. Do you have access to vigorous growing poncirus or an already established tree? that will certainly help boost the growth. 

the prague is on the left, multi grafted taitri


new graft of prague i did to taitri cutting, the whole tree will be prague

[Ilya11]

I don't have fruit yet but when I do I will share the seeds.

Prague is a chimeric plant, its seeds are giving pure satsuma seedlings.

[vnomonee]

Yes, was talking about the taitri seed. i should have quoted the reply

[jim VH]

Lajos93,

It's been in the ground about 8 years, but was probably about two years old when I got it from Stan Mackenzie.  I had to go out and look; it appears to be grafted about a foot high (35cm) on what I think is a PT rootstock, based on the leaf pattern of a rootstock sucker a couple years ago, but it could be Citrange, those being the two rootstocks Stan uses. Note the dense canopy that Prague forms, which is helpful in protecting the inside of the tree from harsh temperatures. Not that it seems to need it at 12F(-11C).

does stan also use flying dragon?

i think my original prague might be on it, it barely grows bud date is 2020

summer 2021


spring 2024

@vnomonee

can you show pics how the prague on taitri looks like right now compared to the one you got from Stan?
really curious to see it in action

I found this regarding hardy citrus (also could work for rootstocks)
https://hardycitrus.blogspot.com/2014/01/cold-hardiness-table_13.html

I know one guy that talks about swingle citrumelo as a roostock that takes -15C and its fast growing, so thats an option as well, but its still a pain in the ass to get any roostock in my country lol.. maybe I could order some from surrounding countries but its quite expensive in large quantities

Answering your question:
I have one fairly large poncirus that was around 6-7 years old when I bought it 2 years ago, it stood there without leaves for a whole year and now its leafing out, I wonder if its a good idea to graft Prague on it?!

[lajos93]

@jim VH

Interesting, fairly good growth then, not a terribly large plant after 8 years, but not too bad
What about the yield? does it give you more fruits you can eat? or would you need 5-6 plants of that size for that goal? haha

[vnomonee]

Yes, graft it to that poncirus! Citrumelo might die back in a severe winter, even though it survived for me -17c once. I don't graft on it, I have tried some but the grafts died in a cold winter while the tree didn't.

I took this video 2 days ago. It shows the prague https://www.youtube.com/watch?v=iB0JH6ukEHw

It blooms profusely, but sets very few fruit, typically 3 pounds or less. I'm not sure if that's because the flowers are not terribly attractive to bees (they aren't) or because Prague's chimeric nature renders the flowers sterile, or maybe both, or maybe something else. I haven't tried hand-pollination. Most of the fruit are golfball sized, like a typical poncirus fruit, but some are the size of mandarins. However, the flavor of all of them is outstanding and I eat them all. They're a bit late ripening in my cool Mediterranean climate--mid-December here--so most years I bring them in before the first hard freeze and let them ripen indoors.
  You might need more than 5 or 6 trees to have more than you can eat, but maybe things would be different in your climate?

[jim VH]

Vnomonee,

Stan 𝘩𝘢𝘴 used flying dragon--two of the plants I got from him are on such--but I'm under the impression that his stock of FD plants is limited; he prefers to use Citrange or PT.
In regards to rootstock hardiness, I agree with you that PT is much hardier as a rootstock than Citrumelo or Citrange. I lost a couple plants on Citrange rootstock during a very long 140 hour freeze with four nights near 10F(-12.2C) because the rootstock died; the plants themselves looked pretty good up until spring.

My C35 rootstock died under my NZL from cold
