That is concerning. I am planning of testing them for the disease, and hope for the best.

Are you using LED? Perhaps you are giving too much light.

Thank you for sharing. Yuzu is generally not known for preciousness, so I might take a while longer before I can expect the first flowers. Some of my carrizo is starting to branch out in the top, at around 2.5, these might be closer to flowering.

Hi, I am germinating some yuzu seedlings, and some of them appear to be variegated. Does anyone have experience with this trait? Does it persist in the seedlings?

I used to have a kabosu plant from a seed that came from a fruit bought in France, but it died while I was on vacation a few years ago.

I still have a sudachi, also grown from seed at the same time, in 2015.



It has never fruited yet but it stays outside all winter here in Antwerp (in a rather sheltered location though). If you're interested I can send you cuttings (tell me how to do it thought because I've never sent live plants through the post) or you can drop by if you're ever close to Antwerp.

That's too bad. Adavo still has some small kabosu plants left, which I might buy.

I already have a sudachi, but I would love to get some budwood  :D

Thank you for sharing. This gives me a good idea of what to expect. How tall would you say a seedling would be on average to reach maturity?

Interesting! I am now growing only the main shoot. Should I cut the heads and let them branch out, or wait for the trees to do it themselves?

Hi,

I have some trees (yuzu) that are reaching almost 2 meters. When could I expect them to become mature? Are there any signs that I can look for when they mature?
The main shoot appears exactly like the new growth I would expect from a grafted yuzu.

@deRoode

I had send you message a while ago, did you get it, or did something go wrong?

I must have overlooked you message. I send you a reply.

Citrus General Discussion / Re: Growing under LEDs
« on: July 29, 2022, 02:48:13 AM »
For the LEDs, it depends on what you want to achieve. Do you want to maintain the plants inside until spring? Then I would say you need minimal light. The risk with having a strong light source is that it might trigger flowering (if induction was done outside) or vegatative growth. If your tree can then not sustain that new growth, due to the climate not being optimal, it can kill your trees. I have unfortunately killed trees by moving them inside and letting them grow uncontrollably.

In regards to the deficiency symptoms; I would indeed start with measuring soil pH! An offset pH can interfere with nutrition uptake.

On a visit to Japan, ( outer Tokyo area ) I saw various Citrus trees in home gardens, and young trees at plant nurseries.
Specialty Citrus fruit was sometimes seen in supermarkets, i.e. unusual Japanese varieties.
I am wondering if there are any Citrus collectors / hobbyists in Japan ?
Any Citrus Forums in Japan ?
It is not hard to find webpages for Citrus farmers growing less common types,
but that is about as far as I have got.

Mature Flying Dragon tree/budwood
In my climate, ungrafted FD seedlings fruit in about 5 years. Also produce some interesting Off Types.
You can speed up their growth by extra heat, shortening the dormancy period.

Many varieties are also available on the Japanese amazon. Due to regulations regulations it's however not possible to import any material into the EU / Export from Japan. Nowadays fruits are being exported from Japan, and that is a way to get the varieties (my sudachi and yuzu are from Japan, and even found an importer selling haruka from Japan).

Interesting about the FD, I will have to try that

Cold Hardy Citrus / Re: C. depressa Shikuwasa Cold Hardiness
« on: July 21, 2022, 04:48:07 PM »
I have a shekwasha on carrizo (still need to take a scion from it to put on poncirus), but no winter experience yet.

On the internet I've seen temperatures mentioned from -12 to -15.
Some of these might be in case the tree is on poncirus rootstock I expect.

I'm from Antwerp by the way, where in the Netherlands are you located?

I have a similar one, also on carrizo. I am looking to use it as a rootstock, but also to graft in on flying dragon.
Do you have any sources on the -12 and -15? I had difficulty finding them.

I am from the south of the Netherlands

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.

A grafted yuzu would be nice, if you have a spare  :)

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 :)

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.

Till

Hi Till, I would be interested in the Tachibana if you happen to have some budwood

Hi,

I have some shikuwasa rooted cuttings, and soon some seeds that I want to use as rootstock. Does anyone have experience how cold hardy it is?

Citrus General Discussion / Re: 4-leaved yuzu Seedling
« on: June 15, 2022, 04:41:12 PM »
Yuzu has a distinct scent in the leaves I am curious if a hybrid would retain the nice smelling leaves, but yes this definitely looks like a hybrid congrats lol

I'm trying to cross my Yuzu with trifoliate, really cool that you randomly got a hybrid from a fruit you purchased (assuming this came from the Yuzu fruit you mentioned looking at your post history).

It originated from a fruit imported from Japan. What are the odds! I will be keeping my eye on this one  ;D

Citrus General Discussion / Re: 4-leaved yuzu Seedling
« on: June 15, 2022, 02:30:10 PM »
It's probably a hybrid if it keeps on putting out trifoliate leaves

That would be my first guess as well!

can we see more of the plant? what do the leaves smell like when you scratch them?



Not sure about the smell, similar to other seedlings I guess?
Apart from the leaves the size and growth is very similar to my other yuzu seedlings.

Hi,

One of my yuzu seedlings consistently makes four leaflets. Has anyone seen this before? Is it common?
Could it be a hybrid?

Citrus General Discussion / Re: Citrus juvenility and internode count
« on: June 12, 2022, 05:01:14 AM »
I have a Yuzu seedling that just started to flower from seed, last season. It has 2 main stems, so would be about 2 metres tall and slightly bushy with side branches.
Haven't counted the nodes, but would be the same for any 2 m tall citrus, not overly vigorous with normal bud spacing.
The plant is in a pot, and has been on the back burner. It is well over 10 years old, but has been neglected over the years, until now it started flowering.
As I recall Yuzu is not one of the faster types to fruit from seed.
Anything that can be done to speed up the growth rate to achieve node count will be helpful., i.e. extending the growing season with protection or heat or repotting as required.

Very interesting! I will be trying to speed up the growth of my seedlings

I am becoming skeptical of the node count explanation as I have a few rootstocks that fruited after the scion died.

Generally I would agree, some plants seem to flower or fruit despite the node count theory.
However in the case of a formerly budded rootstock, was node count achieved by the whole grafted plant,
and flowering maturity transferred to the rootstock ??
Another possibility is flowering hormones from the mature grafted scion influencing the rootstock.

Normally after achieving the necessary node count, all new growth will be adult and can flower. I would agree with you that the rootstock is likely a cutting.

There are some studies were a gmo rootstock was able to induce flowering in a juvenile scion, so it could surely be possible, although the likelyhood of it being a mature cutting would make more sense.


My four winds cuban shaddock's scion died and it flowered and produced fruit.  the rootstock was a rooted cutting.

I hadn't consideres that the rootstocj itself might be a cutting.  Is that common?  I thought most citrus are hard to root.

There are some good protocols for rooting citrus out there, this one for example:

Any chance you would be willing to sell a plant or send some cuttings?

Unfortunately some fungus infected the seeds. Perhaps I can get some fruits next year and try again

Next time send them to me I can help you germinate any kind of seed and send them back.

Thank you! Will keep that in mind!

Citrus General Discussion / Citrus juvenility and internode count
« on: June 07, 2022, 02:51:34 PM »
Hi!

I am quite interested in citrus juvenility. There are some studies that suggest after x amount of plant internodes, the seedling will become adult. One study observed flowering earliest at around the 50th internode up until 120ish internodes. In my opinion, genetics clearly play a role, especially considering precociousity.

Does any one of you have experience with the number of internodes required for flowering? I am especially interested in yuzu, and when to expect flowering in my seedlings  ;D
