Title: My citrus collection [EU - Antwerp]
Post by: Peep on June 30, 2022, 09:15:17 AM
Hello everyone,

In summer of 2021 I started my citrus collection with a few plants from Lenzi, and have kept learning and adding varieties during the year. I thought I'd just make a topic to put some information about my plants, my experiences and people are free to ask questions if they have any.

I'm located in the city of Antwerp and while the back of our house and garden are facing south, the hours of sun can be limited due to walls and buildings blocking the sun. So I keep my citrus plants on a flat rooftop, two stories high up and get a reasonable amount of sun there I think (it's not at the top of the house, I still get some shade from other buildings). Downside is that it can get a bit more wind up there. Other than that, the winter temperatures are not too harsh here in the city I think. According to the book from Olivier Biggio "Agrumes rsistant au froid" I'm on the edge between zone 8A and 8B.

These are the varieties I have now:

- Yuzu
- Yuzu N3
- Smooth Skin Hanayuzu
- Yuzumelo / Yuzu x Citrumelo
- Thomasville Citrangequat
- US119
- Furrowed Bitter Orange
- Taiwanica
- Sudachi
- Eremolemon Coachella
- Prague Chimera
- Shekwasha
- Keraji Mandarine
- Changsha Tangerine
- Okitsu Satsuma
- Maxima Satsuma
- Enzo Pomelo
- Citrangequat 4 Season
- Meyer Lemon


Some of them came from Lenzi and are on carrizo rootstock, so I am taking scions from them and grafting them onto poncirus. I had never made grafts before and from reading on the internet it seemed like I should not expect a high success rate, but it really wasn’t an issue. Most of them succeeded and if they failed it was often when the mother plant wasn’t doing very well at the time or if the scion was just a terrible piece.

Here you can find more information about my plants, the rootstocks, my grafts, and any information I collect:
https://docs.google.com/spreadsheets/d/1bDS69kX9iBFFes3AHoAaj-wvSEzkFKqQe8QJ008WsaE/edit?usp=sharing (https://docs.google.com/spreadsheets/d/1bDS69kX9iBFFes3AHoAaj-wvSEzkFKqQe8QJ008WsaE/edit?usp=sharing)

I’m still looking to add a lot of varieties, this is what I still have on my list right now

These I have no good source for yet (Vessieres doesn't reply again):
- Kumquat Namewa
- Clemyuz22 (or Clemyuz33)
- Kishu(-mikan)
- Tachibana
- Eremomandarin
- Bloomsweet / kinkoji

Quissac has these two, but they are expensive, so still looking for alternatives or get scions:
- Yuzu Nishiki Tada
- Yuzukichi

These I think I can get from Adavo, but I'm still interested in scions (just less of a priority):
- Ichang lemon CRC 1215
- Trifeola
- Satsuma Hashimoto
- Satsuma Iseki
- Citrangeremo
- Eremorange
- Kabosu
- Ichangensis x Sinensis
- Citrus glauca x shekwasha

For these I know someone in France that is willing to send me scions:
- Satsuma Collot
- Satsuma Corsica SRA 145

And this one I should get from a local nursery in August, he says it's very cold hardy, when I go there I'll try to get more information about it, because online there is nothing to be found about it:
- Kumquat Rafael

I'm also interested in making crosses in the future, so Poncirus+ would also be nice to add to the collection.

If you see a variety on my list that is not worth getting, or if you think a variety should be added to my list, please let me know!

And if you can help me with scions, I’d be very happy to talk about that.

I'm also happy to share scions, but I don't know when I will have which variety available as my plants are rather young right now so I don't get many good scions from them.

Here is a picture of most of my plants together:

I noticed you listed Ponkan Mandarin on the don't want list.  Ponkan is not only a good fruit, it is a great tree..  I would urge you to reconsider.  You will be happy if you do.  Thanks for sharing.

Thanks for taking a look! I originally added Ponkan because I read great things about the fruit, but found out hardiness seems to be -9 / -10, while I try to only include things starting at "reported" -12C. It's why I will sell my Meyer lemon, even though the fruit is good. Kishu is an exception on my list because I might like it for crossbreeding (and maybe I also have a weak spot for cute tiny mandarins similar to the shekwasha ;D ).

Hi peep,

I have
- Tachibana
- Eremomandarin (not the cross with Shekwasha)
- Trifeola
- Citrangeremo
- Eremorange
- Ichangensis x Sinensis

I may be able to send you Clemyzu22 and Clemyuz33 the next year. By now, my grafts have not yet budded.

I live near Aachen (Germany), so not so far from you.

Hi Peep,
That is a nice collection you got there! I happened to have bought the Satsuma Miyagawa and Iseki from Adavo this year, so I would be able to send some budwood later this year.
I had ordered some Kabosu from Adavo some years ago, but by now all of the trees have died. They might carry a disease. Anyways, I contacted them and they said they would have new plants available in august this year.

I would be interested in your Yuzu N3 and Hanayuzu if you have some budwood available :)

A really interesting collection, both the ones you have and the future possibilities.
Well over half unknown in Australia, even in research collections.
I hope to learn more about them.

Thanks, I'll keep that in mind about the Miyagawa and Iseki! I am also wondering about the safety of getting Kabosu from Adavo, don't want plants with the HLB virus. I know Lenzi had his Sudachi tested.

Can't promise yet if I'll have budwood available of the smooth skin hanayuzu and yuzu N3, but I will write it down so I can check in autumn. I do have Yuzu N3 plants available that I have grafted this spring, if you are interested.

Thank you. I'm excited about making some crosses myself in the future. This year I removed all flowers and focus on plant growth, so not sure when I will start. Even if I don't create the next popular and useful new hybrid, I think it's still fun and amazing to have some unique plants.

Hi Flos
I thought about asking you if I could just drive up to get 2-2 budwood since Antwerp is just north of my town of Cincinnati Ohio USA.  I am interest in2-2 but more interested in viewing your citrus collection.  After I looked at the map and saw it was a 3 hour drive I decided not to ask you.  My wife also said "NO MORE CITRUS TREES".

Thanks you very much for the offer. Maybe in Autumn is better? I can write your name down and the varieties you have, together with wat Till and Mikkel have, and then see in Autumn what's best regarding who can send what. So the least amount of effort and shipments have to be made by the people helping me :)

Are you mixing up the town Antwerp in Ohio and the city of Antwerp in Belgium? I'm from the latter.

Last Edit: Today at 10:37:37 AM by Peep

I just wanted to see a map of Antwerp in Europe and google sent me a map with driving directions with times to Antwerp Ohio  USA So I thought I would comment on it.  I had no idea that there would be an Antwerp Ohio.  Ohio covers 116096.22 Square kilometers and I only know the Cincinnati corner.  Doe to disease problems I don't swap citrus of any kind.

Didn't expect to get excited about something like new plant pots while I'm in my twenties, but I guess here we are.

Also quite the struggle to find good quality, inexpensive pots that aren't black, too decorative, too ugly, or only sold in bulk for nurseries. Earlier I bought a bunch of brown "Toledo" pots from the Action, but they are only available during spring, didn't expect them to be out of season so quick. Now I've settled for these, bit more expensive, but I like the look better, especially in terracotta color: https://artevasi.com/product/venezia-cilindro-pot/ (https://artevasi.com/product/venezia-cilindro-pot/)
Bought the whole stock from the webshop/dealer most local to me   ::)

Bunch of 20cm pots:

As my rooftop can get a little hot, and I'm not sure the roots would like the heat in the black pots, I'm moving away from them.

And some 30cm:
(https://i.postimg.cc/njv00CLn/IMG-20220705-153307.jpg) (https://postimg.cc/njv00CLn)


Unfortunately my dealer didn't carry the 25cm size, so my quest for pots continues.

Made two grafts today, a Sudachi for @incubator01 and a Furrowed Bitter Orange for myself, both on poncirus. Scions taken from plants that I got from Lenzi, which are on carrizo.

The bitter orange scion:
(https://lh3.googleusercontent.com/pw/AM-JKLX_tzd6SyMaRkT8_cIN7rvIofgewpAJ4DcqvL91B6qe6_jh5DSvZRRXWZ7ymX-7Qf34U1yR7iblSONM5yK6WVpwRZuWnlfZ6ANRojBVG4KHhasxP0vVDEO-4Qp3l7yzS2xVSczr0TLmrZzdbhTozEKa=w532-h943-no?authuser=0)

Cut in the whip and tongue style:
(https://lh3.googleusercontent.com/pw/AM-JKLUkWI1s14GazCCwzU24u1Angz-LljgCejPuZqbvfY-Caq-W8Pdo1nbtUg9XLVGcBpGJVgB9XXNq0uc3b1ZWm3zIE6wDEt2t8QntieHEfopcyWiurI_GAjACtIY2sxRkFat_6tETr03ZBBEw6m-F5IFF=w532-h943-no?authuser=0)

Quite happy with the fit:
(https://lh3.googleusercontent.com/pw/AM-JKLUJ_FmYVWHIsaQn_WG3j8CrGsC-7aje-kuTOsPzZFJFEQpFjI44n_zoEaS0KsWGyOxGKilRZPHF2jk4S4umk2UFYZGhhtPeYFaDaJctf01wGDYnbq5YpbyqBQhUwNh5VK07gTTYnJryTpiLszvyN5Yd=w532-h943-no?authuser=0)

One more angle:

Wrapped in tape. It's grafting tape, but the cheap kind. Not the good/expensive parafilm kind. So far the cheap one has worked fine, but I'm probably going to try the expensive tape soon.
(https://lh3.googleusercontent.com/pw/AM-JKLWN5F9bWNKPDwezpNabWLivbwO242DG8GPgS3q6tqeMHClnZ6qD_cQjx8yjqgo4t4JHlcS82dnawUNrp4gwQqPBf05OnwFSont8FIX-u9aC0iY7HdnZBFHuABTRYMBSEg4m5_8hR9Pu-lPIWKBCnpjW=w532-h943-no?authuser=0)


And bagged, I spray some water inside it for moisture:

The Sudachi scion was quite thin and a bit harder to graft, but it still went pretty well I think:
(https://lh3.googleusercontent.com/pw/AM-JKLX3fPf8124pSKCIqEsqEppzqXiv10hNWF3Kgwgn98-6OPspd073KLnqF354kcjcp15yTNLFVtb3LCOOJDLGvpPcljRagidV_k7Fn_Yq5itycwxiFtL2AglajjkSsb_ASG2B-sl-1tB0b61-XQRzA551=w532-h943-no?authuser=0)

And done:

Also a picture of my Prague Chimera, it really is an unique variety. The young branches are like jello so I put lots of stakes, but it's growing better than I expected:

Nice work. The graft unions are barely visible, especially with the bitter orange. I have always used cleft graft but might just try whip and tongue next time.

Thanks! And I don't think whip and tongue is that much harder than cleft graft. Only when the scion is very thin and soft it can be risky to cut too deep when making the second cut (the little tongue), and when that happens the knife often slips to one side so you just end up cutting a piece off from the scion. Best way I found of doing it is just rocking the knife like a children's seesaw, and not really pushing the knife down or making a regular cutting motion.

It happens on some of my rooted poncirus cuttings:

A lot of plants will do this red thing to protect themselves against UV light damage.

That could very well be possible! These cuttings were recently moved outside, I've now put some plants besides them for shade.

I do also get the dark red/brown new growth on some of my citrus varieties, which I found out is also for of UV protection. But it looks different from the brighter red color on the cutting, I guess either because the leaves aren't as new, or maybe it just looks different on poncirus?

I find it quite fascinating how the plant protects itself like this

It may be a phosphorus deficiency.  Tomatoes look like that when there is insufficient phosphorus.  In any case use a water soluble fertilizer and spray with trace minerals for citrus.

Does someone know what causes the leaf stem/veins to turn red like this?

With Poncirus it is a type of autumn leaf colour change in response to cold, it is a deciduous species.
In a group of seedlings you could get various shades of orange /red on individual trees, up to bright red.
When they are neglected or underfertilized, they will turn colour earlier than trees still active,
so deficiency seems to be also a trigger factor.

The red growth tips on Citrus is as said, UV protection. It is very common in other non Citrus rainforest plants in Australia, highly ornamental.
Red growth tips in Citrus usually indicates Lime / Citron ancestry.
Rangpur, Lemon, Rough Lemons etc also have pigmented new growth.
Some Papedas also have pigmented new growth, i.e. Makrut / Kaffir Lime

It being summer here it's probably not the cold, but lack of nutrients could be it. These cuttings were in sowing/cutting soil (which had few nutrients) for some months without adding any nutrients. Repotted them a week ago and now they do get nutrients, so I'll see how it goes. Thank you all for the input.

Interesting, I'm in Antwerp too.

I don't have a garden though. I used to live in France with a garden and veranda, so now my collection is just trying to survive as it can on my balcony until I move somewhere else with more space.

My own plants are all grown from seeds so they aren't specific varieties, but I just want to say that my C. limon, C. hystrix and C. bergamia trees have been surviving the winters here just fine outside despite not being supposed to be very cold hardy. All growing on their own roots. Also C. junos and C. trifoliata but that's normal for them.

Being in the city helps a lot, and I think we should probably consider our zone to be 9 rather than 8.

Yes, especially if your balcony is south facing and protects against wind. The rooftop that I grow on can still get some heavy wind, but besides this it's a good spot.

Interesting that your hystrix and other non cold resitant varieties have no problem, have you had cold winters since you moved here? For the past winter it's not so surprising, but eventually there will be a winter with some colder temperatures, even if it's just for a few days.

In case you are looking for more citrus plants, I still have 16 plants available for sale https://docs.google.com/document/d/1fajX4HY9GpOcdNYcnwuZrC8mjZdZe6Z8FkhmGQ5onGY/edit?usp=sharing (https://docs.google.com/document/d/1fajX4HY9GpOcdNYcnwuZrC8mjZdZe6Z8FkhmGQ5onGY/edit?usp=sharing)

My balcony faces north-west actually, but there is probably some warmth coming from the windows that brings the temperature up a few more degrees.

I've been here since 2018 and there have definitely been subzero temperatures more than a few times, including a few days at -5C last year around January but I don't have anything less on record at my place. In the first years, I used to bring my plants inside and keep just one specimen of each (among those that I thought might be at least somewhat cold hardy) outside to test it. I did lose a C. australasica and a C. glauca like this. It's no citrus but I also have a Passiflora tripartita (also rated to around -5C, but likely more fragile than the citruses) growing on my house, and I tend to think of it as an indicator that would die sooner than them.

The estimations on the cold hardiness of C. hystrix on the Internet are all over the place, from -8C to +2C, while C. limon and C. bergamia are supposed to be able to withstand -5C or so. In any case I now consider these plants to be mostly fine down to -5C. If it was any colder I would take some measures for protecting them.

Little update.

Repotted and changed the soil of my plants, some of them had some issues with root rot.
Now I used a mix with lava stone and also some pine bark:

9 cups lava (5 cups fine lava 4-8mm and 4 cups coarse 5-15mm)
7 cups potting soil
6 cups pine bark mulch (10 - 25mm)
1 cup sand

Not sure yet if I like using the pine bark, but we'll see how this mix does for now.
Most of the citrus are sitting outside on the roof. After we have finished soms work on a wall that is to the right, I can put them against it. This will help a bit with the wind up there.

I also have a few plants indoors. Two new grafts, a "Smooth Skin Hanayuzu" (from Lenzi) which started growing quickly, and also a US119:

And also a plant (right) where I have made a second graft. First one was Satsuma Maxima, and second (with the plastic bag) is the Smooth Skin Hanayuzu. The Kerji (left) had a new shoot in a spot that would give a nice shape for the plant, but due to the temperatures it hasn't been growing, so I took it inside:

I also made and order from Adavo, which has shipped out today.
I'm still a bit scared of plants from Adavo being infected. I might keep them separate, not really sure how to handle it. Any advice?

I should be receiving these plants:

- Hanayu (Hana Yuzu)
- Hana Yuzu (The "Sudachi" version which isn't Sudachi)
- Trifeola
- Kabosu
- Kishu-mikan            
- Hashimoto Satsuma
- Taiwanica / Nansho Daidai   
- Poncirus x C. unshiu
- C. unshiu x C. junos   
- YUZU N1
- YUZU N4
- Citrangeremo
- Glauca x Shekwasha    
- Ichang Papeda IVIA
- Citrus sinensis "GLORY MIČURINA"
- Triplode Reale (bought for someone else)

Your potting mix sounds very well-draining. That could be a bit too much during hot weather. I once used a similar mix and had to water constantly and the citrus had red spider mites all the time.

I also have a Hana Yuzu "buccia liscia" from Lenzi. It came with a few fruits that really had smooth skin. Oddly enough, later fruits have had a much more bumpy rind. It is not really smooth anymore. I don't have a normal Hana Yuzu anymore for comparison, though.

If you mean a pumice for lava, it could be OK, but at least  in France lava is something else- red colored stuff obtained by grinding of volcanic rock.
It is considered unsuitable for citrus cultivation because of high abrasive action on the roots.

Unfortunately I could not find pumice anywhere, I don't know why it's so rare. Only way I could buy it was a bigbag (1 cubic meter), which is way too much, but mostly the problem is also that I live in the city and we don't have anything like a driveway for them to put it.

Best I could do was this: https://www.compo.be/fr/produits/paillage/autres/compo-pouzzolane (https://www.compo.be/fr/produits/paillage/autres/compo-pouzzolane)

I hope it won't be too sharp. Do you have any other recommendations for something that could be better?

I'm curious if the smooth skin hanayuzu from lenzi is the same as the Hana Yuzu "Sudachi" from Adavo.

For the watering of the plants in summer I might use those drip watering lines, similar to what they use in nurseries. Not sure yet.

Perlite is a good alternative for pumice. Also small clay pebbles.
I personally prefer to use 1:1 mixture of coarse cheap compost  and coconut husk mulch (in France it is sold as Paillage Coco). I  wash it several times with tap water to remove sea salts and equilibrate it with Epson salt solution. Coconut coir is porous and  is  a good exchanger for both cations and anions that prolongates  fertilizer action.

Do you let your plants in the compost/coconut mix stay outside in rainy seasons? With how much rain we got here the past weeks, I would be afraid that there would not be enough air in the soil.

And do you have a preference for perlite or clay pebbles? I find conflicting information about which to use. Or is a mix of both recommended?

I was looking at 8-16mm clay pebbles: https://www.brico.be/nl/tuin-buitenleven/planten-potten/bodembedekkers/dcm-kleiknikkers-hydrokorrels-40l/5156218 (https://www.brico.be/nl/tuin-buitenleven/planten-potten/bodembedekkers/dcm-kleiknikkers-hydrokorrels-40l/5156218)
Or 2-6mm perlite: https://agrifield.nl/products/perliet-100l-zak-premium-perligran (https://agrifield.nl/products/perliet-100l-zak-premium-perligran)

They do stay for almost entire winter outside. Coconut coir drains perfectly, never had any problems with roots.
I guess perlite is good, but has a tendance of floating to the surface, while pebbles should be as small as possible.
Seramis pebbles are among most suited link (https://www.geosism.com/fr/sols-substrats-et-agregats/151-seramis-2-5-mm--1-kg---2-5-l--detail)

Plants from Adavo arrived yesterday. Everything looks alright.

As expected the "chimera" doesn't look like a chimera and probably isn't. I will just put it up for sale as an orange.

Does someone have some insight on the hardiness difference between satsuma and sudachi/kabosu? Not the average satsuma cultivars, but the more cold hardy ones like Hashimoto and Corsica SRA 145. Would it be correct to say that Sudachi and Kabosu are more cold hardy than these satsuma cultivars?

Well drained soil that is being watered constantly is pretty ideal for citrus. They don't like mulch or soggy souls like clay though it's possible for them to grow it's not optimal. Regular potting mix works fine but some sand added is even better especially crushed shells. Our sand in Florida is full of shells high in calcium. Citrus love calcium. Bone meal is good fertilizer for them because of this.

Anything in a pot outside on a hot day needs watered almost every day but they seem to grow fast under those conditions. I started adding small amounts of clay and mulch because stuff dried so fast and it's so hot in Florida. I just mean plants generally not specifically citrus. I did mulch my citrus in a pot for similar reasons. Though normally they don't like dampness associated with citrus in the hot summer they dry out so.fast so it's fine.

Post by: 1rainman on October 12, 2022, 09:17:39 PM
Citrus like to dry out between watering they don't like soggy roots. So it's not a problem if they get really dry for a couple days. Good drainage is good for them. Though they can take a lot of water as long as they get to dry out for a bit. Its more common to over water them instead of them drying out. It's hard to dry them out too much because they are built to keep moisture with thick leaves and such.

Shells are almost entirely calcium carbonate. 99.9% will stay in the shell so crushed shell is almost the same as sand but a tiny amount of calcium will leak out which is good but you don't have to worry too much about it affecting salts, ph or being too much because it's small. But almost impossible for citrus to get too much calcium.

Bone meal will release a lot more calcium and other nutrients as it rots and of course fertilizer with micro nutrients should have calcium. Not sure why citrus like it so much. Never heard of it with other plants other than trace amounts. Here in Florida the river water, tap water etc has a lot of calcium due to the shells and such. It makes for really good soil for citrus. Florida had the best oranges in the world until the greening.

Though shells are alkaline. A small amount shouldn't significantly change the soil. Pure sand is neutral ph though a lot of sand are alkaline due to shells or minerals mixed in them.

For citrus calcium nutrition, I have always used calcium nitrate every 5 or 6 watering.  As far as I know calcium nitrate is just about the only completely soluble calcium fertilizer.

Small update.

Got some poncirus fruit from the botanical garden:

(https://lh3.googleusercontent.com/pw/AL9nZEVUrsA-KAy3UQpjNkwwgrAUWbINiAdjYTJlE2TgOd5cznZFWxkzqhBF4-edjZMk1kc3p6Sca0ovrLpkxHXu8xKqnMU2yGwELHinmy-TJ2a_XvVfRFbQTOYh9aoQ_fT43edgvy3BRJ116oCdBrgWDZjW=w532-h943-no?authuser=0)

Obviously not to eat, but for the seeds. Although I came across one that was seedless, I wonder how often this happens with poncirus?

After squeezing I found one underdeveloped seed:

These two I grafted late in the year, on September 1st. One US119 and one Smooth Skin Hanayuzu. The moisture, sunlight and temperature balance isn't so easy when keeping them inside the house and they don't grow as well as the ones I did earlier, but they seem alright.

Because I bought plants from Adavo, including Kabosu, and there are some rumours about the possibility of it having Tristeza, I have ordered test kits.

These are home kits, it works similar to how covid has detailed PCR tests and also simple positive / negative tests for home use.

Here is more information for who is interested: https://orders.agdia.com/agdia-immunostrip-for-ctv-isk-78900 (https://orders.agdia.com/agdia-immunostrip-for-ctv-isk-78900)

Email reply was quick, shipping as well, will arrive tomorrow. Pricing is 54 for 5 tests and 160 for a set of 25. Shipping to me in Belgium was 28 (FedEx), and with taxes the 5 test kit came to 98,40 including shipping.

Not really sure which plants I will test besides the Kabosu.

This is what I have from Adavo, so can't test them all. Suggestions for which varieties are at the highest risk are welcome.

- Hanayu (Hana Yuzu)
- Hana Yuzu (The "Sudachi" version which isn't Sudachi)
- Trifeola
- Kabosu
- Kishu-mikan           
- Hashimoto Satsuma
- Taiwanica / Nansho Daidai   
- Poncirus x C. unshiu
- C. unshiu x C. junos   
- YUZU N1
- YUZU N4
- Citrangeremo
- Glauca x Shekwasha   
- Ichang Papeda IVIA
- Citrus sinensis "GLORY MIČURINA"
- Triplode Reale

Today I have tested my Kabosu from Adavo for the Tristeza virus. Everything done with care. My result is negative. There is always a small chance that it is a false negative. My plant may not have enough virus or the test may not have been accurate. Or that other Kabosu plants from Adavo have it, but mine doesn't. I can't rule anything out completely, but I can share my experience and the result of my plant and test. It would still be interesting to see more people test theirs.

Unless proven otherwise, I will assume you did everything right and the test worked fine thus your Kabosu is free of Tristeza. I don't have it exactly because I was told by the French that it had Tristeza. Might just get it some time after all..

I believe it is possible for my plant to have it, but not active enough for it to be tested. Some cultivars are more sensitive to it than others.
There seems to be an alternative, but slower, way of testing, where you graft a piece onto a cultivar that is sensitive to CTV. I'm educating myself on it more.

Quote
"The objective of biological indexing is to detect the presence of CTV in plant accessions or selections or in samples whose sanitary status is being assessed, and to estimate the aggressiveness of the isolate on Citrus aurantifolia (Mexican, key or Omani lime), C. macrophylla or Citrus paradisi Macfadyen (Duncan grapefruit) seedlings"
https://www.fao.org/3/cb4687en/cb4687en.pdf (https://www.fao.org/3/cb4687en/cb4687en.pdf)

Unfortunately I do not have any of these varieties, so I would first have to get seeds and grow them. Some people say Bitter Orange is also sensitive, although not as much as the others. I do have a bitter orange on carrizo rootstock that I do not need anymore, so I'm trying to find out if it's worth it to graft kabosu on it. Someone on Facebook also just told me that I can graft a sensitive plant onto kabosu for the same results. I do have Pomelo Enzo, which is a seedling of Duncan, if I'm not mistaken. So I could try that, but my Kabosu is small and I'm not sure it has a good spot to graft to unless I'm ruining the plant itself.

From a quick google I do notice there are quite a few pictures where Kabosu leaves have some wrinkle to them.

I also noticed how round the leaves are. This is also on my Taiwanica from Adavo. They seem to be quite similar actually.
