The fruit is harvested green in summer for its acidic juice.

tedburn> We don't have HLB (and don' t get it hopefully)

bussone> Zone 7 may not be immune from greening. At least, there are enough cold-tolerant plants than get HLB and enough cold-tolerant plants that can host psyllids that it could march north.

Bussone, Mühlacker is in Europe (Germany).  ;)

You mean phosphorous acid not phosphoric acid I presume.

Cold Hardy Citrus / Re: Rooting Prague chimera cuttings

Since this cultivar is a rare chimera, any seeds planted from the fruits are likely to turn out to be plain Satsuma mandarin seeds. Although no one has actually tested that hypothesis, as far as I know.
I did it many times. If not pollinated we obtain pure mandarin but it gets easily pollinated contrary of satsuma.

Well is the new forum.
The old one is .

> I keep it in a more or less 10 Celsius degrees garage, near a window.
If you notice falling leaves, move the pot away from the window.
Search for WLD (winter leaf drop).

Bưởi is pomelo and Bưởi Kỳ Đà is pomelo ky Da.

> In my experience it is hard to ask a native speaker about Citrus, as peoples knowledge varies so greatly, especially for more rare types.
That's true.

> It's my guess its possibly a Citron Pommelo hybrid ??
Don't forget, the leave is articulated and the petiole is not winged. It is nearer from lime or lemon than citron or pomelo.

Yes, but the shape of the leaves don't fit this.

Citrus General Discussion / Re: An identification request for CitrusPages.

Yes it seems its name is Kỳ Đà.
It is called pummelo, lime, lemon or citron.
In some video we can see the leaves. Short not winged petiole and articulate leave.Then it is not a pommelo nor a citron.
Lemons originate in Mediterranean region.
The last possibility is lime...
Now we need a proof.

No but I shall ask.

An identification request from Thailand:
"In Vietnam we have a kind of big citrus fruit but we do not know its scientific name, could you please classify it for us.
Many thanks in advance ”.

I know we've already had this discussion for the Disneyland citrus fruit. But the answer was not obvious...

OK. This time I succeeded!

Usually when one ask to change his password the old password is refused...
Now I shall try to suppress the new account.

Few minutes later: I didn't find a way to suppress an account  :-( .

You better ask on because these numbers are only used in  France.

Cold Hardy Citrus / Re: Can citrus survive winter without sunlight?
« on: August 02, 2021, 04:16:15 AM »
In the old forum someone posted about how they had kept plants in total dark and cold for several weeks before they started to lose leaves.
It is not saying they loose their leaves at the end!
They have been the whole winter in full dark (15 weeks) and didn't loose any leaf.

I already had 45°C/113°F in my green house and nothing happened.
Obviously, if the pots were dry the citrus would have died...

Indeed, everybody does as he wants.  :)

Everything you tried or said is wrong. Sorry...
Citrus love water. The issue (probably phytophthora) is the lack of oxygen in the ground.
- don't use terracotta pots. Use plastic pots. make ~2 cm holes every 10 cm on the sides of the pot but completely at the most down place, against the bottom. Or buy pots that have this holes. The are becoming very common.
- use regular soil for plants and flowers that you find in any garden shop they keep water and drain enough. And nothing else! like bark, clay pebbles, perlite, pumice...
- never let your soil dry.
- always re-pot in a pot 4 cm wider (2 cm on each side).
- try not to move your pots or no more than twice a year to take them in and out.

Most of my citrus are always out side and believe me, they are very happy when it rains.

About your pursha:
- 40°C don't kill the roots
- loss of roots, loss of leaves and full of flowers means death is near.
Your citrus have phytophtora. To try to save them you might treat them with fosétyl-Al.
And you even are not sure to save them.  :(

You made a mistake. Prague chimera is a chimera but Citrondarin is not, and we see it on your faces!...
Next time, taste the right one!   ;D

It works for me too now!  :)

No! It is not dangerous! :-))

Citrus General Discussion / Re: What lime is it that I had in Costa Rica?
« on: October 26, 2020, 09:56:35 AM »
Rangpur lime (C. limonia) is C. reticulata × C. medica.
Mandarine is the female parent and citron (not lemon !!!) is the male parent, like ‘Rough’ lemon (C. jambhiri), ‘Volkamer’ lemon (C. limonia Osbeck) and C. karna.
The mandarine is the ‘Cleopatra’ mandarin from the acid mandarin group.

Citrus Pages is wrong on this subject. I shall correct it as soon as I can.

Shekwasha is very common in Europe and we use to give budwoods for free.

Arsenicum is not a heavy metal.
