Cold Hardy Citrus / Re: Citrus damage after freeze
« on: January 04, 2023, 10:06:27 PM »
8 F, 13 C was not cold enough to differentiate a lot between most hardy citrus.  Both types of 10 Degree Tangerine appear to be more sensitive to the cold than expected, leaves curled more than most.  Brown Select, Changsha, Keraji appear to have done well.  Sugar Belle will probably lose its leaves, but seems to have survived.

Cold Hardy Citrus / Re: Tetraploid Citranges
« on: December 31, 2022, 01:46:46 PM »
Tetraploid plants have larger stomata than diploid plants.  I am looking for a way to view them to compare.  There are add on magnifiers that can be used on smart phones, and regular microscopes.  Has anyone tried this method and what are their experiences?

I have a couple of non bearing trees that look just like a satsuma but did well in the latest cold. Low was 8 F, -13 C.   Leaves are not curled.  I can't tell yet if this is or is not a hardy response.  At the moment it appears that the cold was not severe enough to really separate the hardiest trees from the less cold tolerant.

Very nice assortment, you have almost all the varieties I am looking for.
It makes you want to see it all up close.  :)

Can you tell me what are the taste characteristics of Dallas citrumelo and Taichang lemon?
Some people mention that Taichang Lemon can withstand -15C but others say -9C.
What about your experience with this one?
These are not my fruit.  They were brought to the meeting by others.  It was a missed opportunity to not sample the fruit at the end of the meeting.

Any info on the Dallas citrumelo? my first time hearing of that unless it goes by another name. How was the taste?
There was no information about Dallas citrumelo.  Assume it bloomed the first time in Dallas. 
I only sampled Prague, which was very good.

"The dry fruits are probably due to growing conditions. Perhaps a bit too shadowy. Those fruits that were not dry were quite juicy. Fruits were sweet and not bitter. All seeds were underdeveloped."


What are you growing?

Have there been any discussions on next year's location?
Next year marks the 20th annual Citrus Meeting.  It was started by Stan McKenzie and he has been the driving force behind it every year.  He announced that next year is his last year organizing it.  It sounds like Clemson is going to be taking it over so if that is the case they will probably be located near coastal SC.  There was no announcement of where it is going to be held, the news doesn't usually show up for several months on FB

Cold Hardy Citrus / Re: Thomasville v. Morton?
« on: November 14, 2022, 02:38:17 PM »
Is there anything to recommend a Morton over a Thomasville, or is the Thomasville considered superior in basically all comparisons?

It seems to have better vigor, fruit, and hardiness than the Morton.

I ask only because the neighboring town is called Morton and thus the name appeals to me, but aside from that I cannot fathom a reason to prefer it. Anyone with a minority view?
The one fruit I had from Morton was attractive but not edible out of hand.  A ripe Thomasville is edible when ripe and can be used before as a lime substitute.
For breeding purposes, others have posted that they got a deciduous seedling from a Morton, and that Thomasville is not zygotic.

Citrus General Discussion / Re: US119 flavor
« on: November 10, 2022, 01:22:51 PM »
I read that US119 should have a hint of banana and Mango flavor. Is that true?
Yes.  I tried it a few years ago at the Southeast Citrus Meeting in South Georgia.  It was good.  One long time grower said it was his favorite.  They split if they get too much water.  I lost mine in a deep freeze.

This topic has been discussed in this forum and in its earlier version. 
To summarize, in cold weather, citrus go dormant.  They don't need sunlight.  They can be kept in the dark for up to 15 weeks without harm as long as it is cold.
Using covers that let light in can warm the tree up sufficiently that it is no longer dormant, a problem if the heat source is lost and it freezes inside.
Cold soil and warm temperatures inside the cover can lead to leaf drop.
Putting a tree in the basement or garage is sufficient most of the time. 
A dark tarp cover and a heat source can work.

US119 has a unique flavor, citrus, with banana mango overtones.  Easily splits from too much rain. 1/4 poncirus.

Mikkel, Do you still have these plants?  Are they still different looking?

Cold Hardy Citrus / Re: My citrus collection [EU - Antwerp]
« on: July 13, 2022, 07:30:46 PM »
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.

41
FFP seem to be sensitive to conditions in a pot.  Maybe it applies to standard Poncirus as well. The ones growing in pots have very few leaves while the ones growing in the ground are fine.  Uneven/incomplete  watering or other stressful conditions could be sending  the message, 'Wait for a more favorable  environment before sending out new growth' 
Can you plant your Poncirus in the ground?

42
They will soon kick off extra fruits.  If there are too many in a month from now, thin them then.

In South Florida, my grapefruit would start to be pickable but still be sour in December, and then continue to sweeten until May or June, when they would fall off the tree.

Danil, what is your climate zone?

It sounds like you are going to grow plants indoors as key lime is very cold sensitive.

Citrus General Discussion / Re: Juice concentrate?
« on: May 05, 2022, 11:55:55 PM »
When possible eat the fruit and not the juice.

Juicing fruit takes away the fiber that slows down absorption of sugars, and thus slows the sugar spike.  Fiber also has nutrients.

Citrus General Discussion / Re: Pollen collection and storage
« on: April 21, 2022, 02:10:57 AM »
Use foam type swabs to transfer pollen. I don't know what type and style of foam is normally used for this application, i.e., polyurethane, polystyrene, silicone, etc.

I ordered

Polyploid plants often have thicker leaves and more serrated leaf margins

49
My best guess  either the spray was over applied, sprayed in the heat of the day, or not a low biuret variety

I believe it is not low biuret.  The package did not indicate.  The data sheet said it was low biuret.

Urea from Alpha Chemicals caused extensive burning of leaves.   Defoliation goes from none to complete leaf loss depending on the plant.  There is some minor damage on most trees.
