Thank Socal2warm for sharing your experience in a very detailed manner.

Thanks Socal for your extremely detailed description. It is very helpful and enjoyable.

  I just thought of a reason explaining why the ichang papeda displayed more leaf damage than the yuzu did. Perhaps ichang papeda responds better to cold weather than yuzu, so it went through some internal chemical changes to signal the leaves to turn yellow and probably prepared for falling off to conserve energy. A good example of this is Poncirus Trifoliata which will drop all its leaves at a temperature below 50F. If this hypothesis is true then ichange papdea is absolutely more cold tolerant than yuzu. We might need more observation to come to a final conclusion.

  I am guessing that a citrus variety which has leaves most sensitive to cold weather could be least suffered bark damage.

I agree it's certainly true Ichang papeda is an oddity and would not be a recommended variety in zone 9, and maybe even 8b, but it is one of the few things that can grow well outside unprotected in the colder parts of zone 8 in cooler more northerly climates, or possibly even the warmest part of zone 7 in the US South.

 My ichang papdea leaves just turn slightly yellow with loads of small yellow spots after the temperature dropped down to 37 while my yuzu seedling was still doing great. My Harvey lemon also did not show clear signs of suffering in its leaves, and its leaves were still vigorous though the tree stopped flushing with any new bud.

  I brought my ichang papeda inside because I did not want to lose its flower buds. I left my yuzu seedling outside last year and it lost all it leaves but survived without any damage. I personally think that ichang padepa would be less cold tolerant than yuzu, and if this assumption is true, it surprises me. 

  I live in zone 8a.

That photo is clearly Yuzu...

 Yuzu fruits when riped will turn to orange color. There were several different variants of Ichang papeda. The one Socal posted was a variant of Ichang papeda fruit. The one I have now is from an Ichang papeda tree that had similar fruits to the ones posted by Socal.

Poncirus does not require any care even when inpot. It will make it through winter easily without any attention unless you live in a region lower than zone 5.

I don't think a hybrid of Ichang Lemon could survive in zone 7. My pure Ichang Papeda grafted on PT could barely withstand the winter in zone 8a. It barely survives, but most leaves would be damaged and fell off. Ichang Papeda also flowers and fruits during winter which make it a useless source for hybridizing program unless you just want an ornamental piece of citrus.

My IP is vigourous, i use it as a rootstock, good root resistance, tolerates alkaline soils quite well.
I really doubt that is precocious.

 My Ichang Papeda is not vigorous at all. It is an extremely slow growing one even with loads of leaf grow boosting fertilizers. It tends to grow horizonally rather than uprightly. The graft took place about 12 months ago. it is like a bonsai in a small pot. I personally think it will tolerate in that pot for at least 3 more years before upgrading to a bigger pot.

  I like the way it looks. It probably has the most beautiful foliage shape among citrus varieties. The only thing I don't like about it was the ridiculously large and long thorns. I should have spent time to pinch all thorns with a nail clipper.

  My Ichang Papeda just started to flower recently in late fall. This the first time it flowers. I just wonder whether or not will it flowers through out the year.

  I grafted a small branch of Ichang Papeda on a young Poncirus seedling last fall. It surprised me with its flowers at an early age. The rootstock is now not even 1.5 years old. It currently has tiny flower buds all over the branches.

  Please share your experience about this papeda.

California has a special program (CCPP) where you can have budwood mailed there, and they will test it to make sure it doesn't have greening disease and propagate it, and then you can eventually have them send budwood. That might be the safest way. It's not too expensive.

 Thank SoCal, it's good to know this.

>I will probably try to sneak some scionwood into the US.< 

911311, that sentence says a lot about your character.

 Lol you should not judge anyone here about their character. This forum is not designed for judging each other. As a mod you should know this. Think about it and look at your judgement.

12 will soon have seedless yuzu available on their webpage. This seedless yuzu is not a special tree for collection. They are very cheap and so common in Japan. If I have a chance to get back to my country, I will pay a visit to Japan and buy several nice citrus varieties overthere to multiply them in my homeland. I will probably try to sneak some scionwood into the US.

   These citrus might only be rare to those selfish collectors in US and the Europe. There were bunches of excellent citrus varieties in Asia to be considered. Nothing special about citrus to be collected. No body cares, and no body praise for the possession of such citrus trees.

They are available in the US...

 Really? May you please share the secret place to buy it from?

   There were several types of seedless yuzu but not available in the US. If we have the seedless variety, why should we go for the extremely seedy one?


   I have been searching many places online within the US for seedless yuzu but no hope yet. If I found a reliable place to buy I would post it up here so everyone can go get one.


  I've checked everywhere in the US but could find a seedless variety of yuzu. The normal seedy yuzu is now everywhere but it was impossible to find it outside of Japan. I am happy with the less seedy yuzu as well.

  I would appreciate so much if someone find me a place to purchase one.

 Thank you very much

Bye hardy citrus. Don't waste time on something impossible. Enjoy something that is tangible. Grow something that we can eat while we are still young. No space in garden for stupid hardy citrus.

Temperate Fruit Discussion / List of best rootstock for jujube?
« on: January 07, 2019, 10:03:43 AM »
  Does anyone know any best dwarf rootstock for jujube?





My experience with high crafting is a bit mixed up. I have a Citrumelo, a Citrandarin and Chimera Prague high crafted at 120 cm. The stem of Citrumelo (dm 3cm) was severelydamaged by rind cracks. Cracks were only to be found on Poncirus-stem. Cirumelo parts were completely okay. I think it was exposed to the sun. The other stems were not harmed at all. Citrumelo recovered and bloomed late but plentyful. Last flowes in Dec.

  Cool, I think high graft on FD is safer when the tree is still young. I plan to reduce size all my trees using FD rootstock because it is much easier to cover the entire canopy by plastic bags. I think we better water the entire tree before cover it as well as paint lower trunk to protect from insects and cold air. Thank you for your opinion.
