Citrus General Discussion / Re: Oroblanco
« on: April 11, 2019, 07:33:20 AM »
My seed-grown Sweetie is starting to flower for the first time after 4 or 5 years (I am not sure which year I planted the seed). I reckon that is quick enough for Switzerland. I hope it does not stop next year and take another couple of years to flower again.

It used to have much larger leaves but perhaps the pot is too small..
I will try to graft it onto Poncirus next year.

Cold Hardy Citrus / Re: Today, I've put my ichangensis IVIA in the ground.
« on: April 06, 2019, 10:19:27 AM »
The IVIA survived its first winter fine but it does not look too happy. However, it started to look like this last year already, so this does not seem to be a winter problem.



I was a bit surprised by the differences between the two backup plants I grafted last year. The left one is already flowering. They are on identical rootstocks in identical substrate.

How cold do you reckon it was inside the Bloomsweet enclosure? I have a seed grown plant which is flowering for the first time.

I would say the climate here is pretty similar to where you are. From my experience so far I would say that, even with a cover, and even close to the South-facing side of the house, Bloomsweet is borderline in this climate. It might survive or might not. It's pretty "iffy". The Bloomsweet is still alive, but it still remains to be seen if it can put on enough growth so it does not decline. But it was also a colder Winter than usual here, that's something else to consider.
You may not want to risk your seed grown plant.

But this may be encouraging. Ilya posted a picture of his Bloomsweet (just outside of Paris) in the thread "Cold Hardry Grapefuit/Pommelos" on page 2.
http://tropicalfruitforum.com/index.php?topic=18992.25

So apparently it is possible for it to survive in Europe.


I made a mistake, it is not my Bloomsweet that is flowering but my Sweetie, sorry ;D. I confused the two in my head.

Ooh, yes, I love the smell of crushed lemon leaves. This actually is what got me hooked on citrus. Combava leaves are great too.

That's about what I expected but you will have guessed that it won't stop me from trying. Thanks a lot anyway.

Citrus General Discussion / Honey Pomelo seedlings
« on: March 15, 2019, 02:28:55 PM »
These are usually seedless but this winter I had a fruit that was full of large, flat seeds. I sowed them and they took their time but many germinated.

Now, I am wondering what to do.. I know pomelos do not come true from seed and our climate is much too cold to plant them in the ground but I'd still like to give them a try for the sake of it.

How long would they take to flower anyway? Any suggestions are welcome.

It is the ordinary Arbutus unedo. I will snap a pic when I get around to it.

I have one and I am in zone 7b/8a. It does well enough and always looks good. I was told that below -15C it can freeze back. We haven't seen such temps since it was planted, so I cannot comment on that.

It is a lovely tree, care-free and a bumblebee magnet late in the year. It tolerates pruning very well.

Citrus General Discussion / Re: Grafting with micropore
« on: March 11, 2019, 08:27:43 AM »
I have not heard of this material and have used Parafilm so far which has worked great. I usually wrap the union and the scions too and there has never been any mould. Would micropore be cheaper than Parafilm?

Cold Hardy Citrus / Re: How hardy is TaiTri?
« on: March 10, 2019, 10:24:50 AM »
Thanks! I know that Taitri isn't supposed to be very good tastewise but I am happy with anything even slightly better-tasting than Poncirus as long as it survives our winters and is able to ripen. Would Taitri be more coldhardy than Citrumelo?

Here are some of my seedlings. I have to keep them in community pots because of lack of space. I use a well-draining substrate in order not to over water them and to be able to seperate them easier later on.

I have a bunch of seedlings from seed eyeckr kindly sent to me. I wonder how they handle European (i.e. Swiss) winters. USDA zones are only of limited use over here. This winter would have been 8b/9. But our winters are long and damp, days or even weeks below 0C occur every so often.

 Thank you, Laaz. How did you get it in the first place? Was it from seed?

Florian This link gives you the answer.
Unfortunately in French.

http://www.fruitiers-rares.info/articles63a68/article67-semis-Poncirus-trifoliata-et-variete-monstrosa.html

So I allow myself to quickly translate the most important.
The origin of this is genetic but most often the influence of a fungus Aspergillus flavus and Alternaria tenuis present on the seed coat.


Thanks for the link. French is fine, I am Swiss after all..;-).

But whose plant is this chimera above (or whatever it is)? I would like to learn more.

Cold Hardy Citrus / Variegated Poncirus
« on: March 06, 2019, 05:16:49 AM »
I was browsing citrus pages when I saw this picture of a variegated Poncirus.


Is there any information available? Is there anyone growing variegated Poncirus?
Thanks!

Cold Hardy Citrus / Re: Citrus seed germination beginning in 6 days
« on: March 01, 2019, 03:00:32 PM »
I have had excellent and quick germination with Taitri too. I used the baggy method with perlite and put it on a radiator. No albinos so far.

You are much ahead of us. Here, citrus do not flower before April or even May.

Citrus General Discussion / Re: Tiny dragon flying dragon trifoliate
« on: February 26, 2019, 04:41:20 AM »
I found this link: https://mrmaple.com/products/buy-poncirus-trifoliata-tiny-dragon-dwarf-contorted-hardy-orange

It says:
'TIny Dragon'  is a dwarf contorted hardy orange with thin thread-like leaves. The branching is even more contorted than 'Flying Dragons' and is much slower in its growth.Ted Stephens and Rick Crowder found this hardy orange at a garden center in Japan as they were leaving Nagoya headed toward Gifu. While Ted ended up calling this selection 'Baby Dragon', Rick ended up calling this tree 'Tiny Dragon'. Either way, this dwarf contorted hardy orange stays small and is a great candidate for growing in a fairy garden or container. 'Tiny Dragon' may reach 4 ft by 4 ft in 15 years.
The fruit on 'TIny Dragon' is rare but tastes quite tart, similar to a lemon. The fruit of this species is often used in making marmalade. 

So mine is not the Tiny Dragon, just tiny 8). Ilya, you are most certainly correct in assuming it is the rosette-type. Because apart from having extremely short internordes, it is also supposed to have thick roots, which, in fact, it does have.

I haven't heard of it either but I have a couple of FD seedlings that are much tinier than my other seedlings (also FD).

One year old

Cold Hardy Citrus / Re: Hardy citrus growing in Switzerland
« on: February 23, 2019, 10:17:45 AM »
Yes, the temperature near the house is warmer here too. But it is not enough in a cold winter with extended freezes. Last year, I lost a Citrange only about a metre away (in the pic on the right where you can see a few leaves of the changsha I put in its place, which btw. also survived unprotected).

If only all winters were like this one. Where I live, the absolute has been around -5/-6C.
My ichangensis x sinensis is not impressed 8).

I have a K which is also monofoliate. Btw. I thought they went from A to R not only K.

Check out the Hamlin x FD: http://tropicalfruitforum.com/index.php?topic=28270.msg321750#msg321750.
It appears to be rather coldhardy.

Cold Hardy Citrus / Re: Trifoliate hybrid ID
« on: January 26, 2019, 04:08:00 AM »
Ok, I see. That makes sense. Mine is grafted. But then I am not convinced the above plant is Thomasville since almost all of its leaves are trifoliate (although on some the two side leaflets are very small).
