I found three fruit on my yíall from-seed Changsha last November. Last week after removing the winter plastic from its frame, I noticed some flower buds. Itís been so warm this winter and spring with some highs in upper 70ís, I had to take down my plastic. We had a low of 35 Saturday, was supposed to get to 29 degrees F, but thank goodness I dodged that bullet. Supposed to get to 35 again this Wednesday. All my other citrus are budding out too.

Cold Hardy Citrus / Santa Teresa lemon
« on: December 08, 2019, 08:39:53 AM »
I just received my Santa Teresa lemon tree from Four Winds. 1. What is their ďsemi-dwarfingĒ rootstock?
2. To what degree F is this lemon tree hardy to? Iím planning on keeping it indoors in pot forever assuming it canít handle temps below freezing.

Cold Hardy Citrus / Seedless citrange
« on: November 25, 2019, 07:30:16 PM »
Iím wondering if these two citranges got mixed up or switched names: the Benton looks bright orange and has seeds, but the citradia is yellow and seedless. The citradia that the grower showed me last year was bright orange, and Iím used to thinking citrus aurantium as being orange and the seeds in it being used for pectin. Does Benton citrange tend to be seedless and yellow, or are citradia fruit usually seedless?

Cold Hardy Citrus / Lobed citranges

What causes some citranges to sometimes be lobed and sometimes smooth spheres? These are Benton and citradia at the Southeastern Citrus Expo in Bolivia, NC today.

Citrus General Discussion / Is greening in fruit or seeds?
« on: November 22, 2019, 09:02:44 PM »
I think I learned on this forum a while back that they have determined that greening disease is not found or transmitted by fruit or seeds. Am I right?

Cold Hardy Citrus / My first poncirus marmalade tastes good.
« on: October 28, 2019, 08:56:26 PM »
My trifoliata trees finally produced enough fruit for me to try making marmalade and it turned out to be surprisingly good! I basically followed the sure-jell recipe but pored off the boiled water from the chopped peels and just added the peels to the fruit pulp/ juice. It ended up being 2.75 cups of pulp/juice and 1.25 cups of water, sure-jell, 5.5 cups of sugar. The final product tastes like a strong yet sweet orange marmalade with no bitterness. There was no resin sticking to my teeth after eating the marmalade either. I just used standard poncirus trifoliata fruit for this batch, not the flying dragon.

Citrus General Discussion / Uses for poncirus trifoliata?
« on: May 27, 2019, 01:49:08 PM »
I have a bunch of PT seedlings. I remember someone on this forum wanted a bunch of fruit to treat cancer. Iíve tried to research treatment of cancer with PT but canít find anything telling me how to process it or who I could be a supplier of fruit for. Anyone know of a profitable industry for poncirus other than root stock?

Cold Hardy Citrus / First good Rio Star grapefruit in 5 years.
« on: February 04, 2019, 09:46:20 AM »
Iíve been caring for this tree for the past five years or so. Usually fruit gets damaged by cold even in enclosure, but this winter has been the warmest here Iíve seen in years with my lowest recorded temp so far being 11 degrees F, and temps have gotten above freezing every day.  I ate this grapefruit today and it was the best quality one Iíve ever produced here. 6-7 more fruit still on tree. Hope my Croxton fruit are good too. More Rio Star pics to follow.

Cold Hardy Citrus / Citrus cold frames held up under 20 inch snow storm.
« on: December 10, 2018, 08:43:17 PM »
The space heaters inside helped melt heavy snow off tops of covers. My boxier frame with flatter roof held snow but I think the thermo cube for that heater malfunctioned so I went to Tractor Supply today after the roads were cleared and got another one; supposed to get down to 24 degrees tonight.

Cold Hardy Citrus / Name game
« on: November 03, 2018, 07:28:56 PM »
Poncirus trifoliata x mandarin = citrandarin
Ichangensis x mandarin = ichandarin
Poncirus trifoliata x citrus aurantium = citradia
Poncirus trifoliata x pomelo = citrumelo
So, ichangensis x citrus aurantium = ? ( ďIradiaĒ, ichantiumĒ, ďichadiaĒ?)

Cold Hardy Citrus / Parentage of a hybrid?
« on: October 31, 2018, 08:29:54 PM »
I should know the answer by now, but I know several of you can elaborate ad nauseum and enlighten me: When trying to create a citrus hybrid, does it matter which of the parent trees serves as the mother or father plant? For example, Iíve learned Ichang papeda doesnít come true from seed, so if I want a hybrid of ichangensis with Seville sour orange, I would want the ichangensis to be the mother plant, no?  If the sour orange was the mother pollinated by ichangensis, there would be less chance of getting a hybrid offspring since the orange is polyembryonic, right? So when the citranges were created via hybridization, which was the mother plant, the trifoliata or the orange? Did it matter since oranges and trifoliata both tend to come true from seed with low chance of producing a hybrid? Could I pollinate both parents with each otherís pollen and then watch the seedlings of both sets of fruit to look for hybrids?

Want citradia seeds, seedling, grafted specimen.

Cold Hardy Citrus / Poncirus juice resin settling procedure?
« on: October 29, 2018, 06:53:56 PM »
Someone posted recently about putting poncirus juice overnight in a glass ( I presume in refrigerator) to let the resin or poncyrus nastiness to separate from the juice, and then youíre left with good juice. How do you separate the nasty layer from the good? Is the nastiness floating on top? Do you scoop it out with a spoon? I canít find the post about it.

Cold Hardy Citrus / Name that citrus.
« on: October 28, 2018, 09:17:23 PM »
I went to J.C. Raulston Arboretum in Raleigh, NC today to see their Dunstan citrumelo and citradia trees. The Dunstan was obviously Dunstan. However, the ďcitradia ď which they seem to have misspelled ď poncirus trifoliata x citrus auranticumĒ looks like Swingle citrumelo to me. Iíve never seen actual citradia fruit before, so I canít judge. The photos Iíve seen of it online vary greatly. Iíve seen long lumpy sour oranges before, but photos of sour oranges such as Seville seem smooth and round. Could this pear-shaped yellow fruit be a form of citradia?

Cold Hardy Citrus / Large poncirus fruit!
« on: October 27, 2018, 06:48:45 PM »
These poncirus came from a neighbor down in the valley. He said the tree has been growing beside their trailer for 30 years.

Citrus General Discussion / Nitrogen deficiency?
« on: September 17, 2018, 05:28:21 PM »
Dunstan citrumelo. Has lush green sucker coming from base and rest of tree is yellow. Been fertilizing with miracle grow and super thrive. Suggestions?

Cold Hardy Citrus / Rio Red blooming after winter defoliation.
« on: April 30, 2018, 08:14:32 PM »
My big Rio Red grapefruit is blooming like mad even on wood that lost leaves after hard freeze in greenhouse this winter. The small space heater in it's greenhouse didn't prevent the water barrel inside from freezing the week of January it didn't get above freezing. The tree partially defoliated. Branches that lost leaves but not wood are covered in small flower buds. Parts of tree that didn't defoliate have older more developed flowers.

I'm tired of Ichang lemons freezing to death here, so anyone who wants to drive to NC and pick them up, come on. I have in 1 to 10 gallon pots:
Ichang lemon
Mandarin seedlings
Just sprouted "seedless" Ichang lemon seedlings from Dr Hanna project

I'm not mailing any of these. I grew all from seed. Some of the sanguinelli have dropped leaves from freezing in greenhouse this winter but most still have green stems and will probably leaf out like other stuff in greenhouse.

Cold Hardy Citrus / Swamp Lemon Adventure!
« on: February 11, 2018, 12:15:18 PM »
I am currently en route, embarking on an exciting adventure, to Delco, NC in search of the elusive and highly sough-after Swamp Lemon! I'll let y'all know if I find some. Hope to find some seed-filled fruits in a ditch off of hwy 74, or maybe a local nursery will be open tomorrow and have a lovely assortment of potted specimens to choose from at a very low price! Got it all figured out.

Cold Hardy Citrus / Picked some freeze-damaged Croxtons
« on: January 29, 2018, 09:46:07 PM »
Actually, don't seem to be ruined on the inside and although still not pink, is edible after a taste test.

This past three weeks below freezing destroyed all of my water Barrels. They completely froze and busted at the seems. 15 or so cans lost means I'm not replacing them. These trees can either survive without protection or die. I'm over it.

Cold Hardy Citrus / Snow-kissed satsumas!

Had to cut me some Owari for my lunch this week.

Cold Hardy Citrus / Ichang lemon seeds in refrigerator.
« on: December 10, 2017, 06:08:56 PM »
Can I put some of my seeds in wet paper towels and put in ziplock bag in refrigerator and then plant seeds outside in spring?
