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?

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!

These poncirus came from a neighbor down in the valley. He said the tree has been growing beside their trailer for 30 years.

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
Sanguinelli
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.

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?

Citrus General Discussion / Ichang lemon pie; fruit from SE citrus expo!
« on: December 04, 2017, 07:16:57 PM »
One Ichang lemon produced 1/4 cup of juice which was enough for pie recipe, was acquired from citrus expo in Savannah this year, from Dr.  Hanna's seedless ichang project.  They were giving fruit away there. There were 10 seeds in the large "seedless " lemon. I love Ichang lemons; strong lemon smell from whole fruit, and juice from fruit made excellent lemon pie. Not bitter at all. Yes, I planted the seeds!

Cold Hardy Citrus / Upgraded cold frames for growing trees.
« on: October 09, 2017, 05:00:27 PM »
My seedling Changsha is getting too tall and Rio Red on FD is bigger this year. Will cover them in 4 mil plastic and have one side to roll up on east side of structure to vent on warm days. Space heater with thermo cube in each. Plan to disassemble the Rio Red frame next to house in spring and put up again next fall; used screws.

Citrus General Discussion / Growing lemons from seed?
« on: July 09, 2017, 07:53:30 AM »
Ok. I just read a post on FB about growing your own indoor potted lemon tree from seed to get fruit, etc. photo shows a 12 inch high lemon tree loaded with lemons in a two gallon pot on a window sill. A small productive lemon tree is grafted, right? Lemon trees still have a significant node count requirement like other citrus right? I've not tried to grow sweet lemons from seed, just Ichang lemon, but still doubt that I could plant a grocery store lemon seed and get fruit off a foot-tall tree. Enlighten me please.

Citrus General Discussion / Air propagator question.
« on: June 19, 2017, 09:44:53 PM »
I have some of these air propagator clam shell devices and want to try it on some citrumelo branches. How long should the branch be that I'm trying to root? I have the small and medium size propagators.
