Temperate Fruit Discussion / Squirrel repellent?
« on: July 19, 2020, 02:03:45 PM »
Squirrel are taking my unripe pears and peaches again. What herbal/natural Concoction can I spray on the fruit to deter the vermin? Peppermint essential oil solution maybe? News flash! Plastic owls donít scare anything! The squirrels skip happily under the electric fence too; itís just to keep bears and deer out.

Temperate Fruit Discussion / Glechoma hederacea killing apple trees?
« on: July 18, 2020, 10:34:11 PM »
I have a thick Creeping Charlie (glechoma) infestation in my apple orchard and I think itís alleopathy is killing my trees. Does anyone know if this weed can poison apples like black walnut does?

Temperate Fruit Discussion / Russian black apricot crop

My first Tlor Tsiran Black apricot crop. All my other apricot trees dropped all their fruit this year except this one and my mume.

Citrus General Discussion / Grafting question:
« on: July 16, 2020, 08:29:38 PM »
I grafted citradia onto FD, cleft graft, and parafilm taped it to the end as I have seen others do online. They said leave the tape on and just let the new growth fight itís way out. My instincts tell me to remove at least some at the end so the new growth can develop easier. What should I do, yíall?

Cold Hardy Citrus / Cold hardiness of bergamot?
« on: July 06, 2020, 08:55:19 AM »
After doing a lot of searching online, I am not finding a good reliable answer to how cold hardy bergamot is. Iíve seen on Daveís Garden that itís hardy to 35 degrees F, and somewhere else 30 degrees F, and that they are one of the least cold hardy citrus and only grow well in the Mediterranean. Iíve also seen a lot of discrepancies about whether or not it is genetically citrus aurantium of variety bergamia, or part lemon of lime. I thought aurantium sour orange is supposed to be cold hardy. Ilya says his is in a pot, so Iím assuming bergamot canít handle freezing temps well. I was planning on planting mine ( on flying dragon rootstock) outside one day and protecting it with a cold frame with space heater like I do my satsumas, but if it cannot survive 25 degrees F,  Iíll have to bring it in the house in winter. I look forward to the expert opinions and answers to follow. Thanks in advance!

Will this cleft graft of citradia on poncirus triangle shape wood work?

Citrus General Discussion / Mailing citrus seeds?
« on: June 24, 2020, 07:32:40 AM »
Are we allowed to mail citrus seeds from state to state in USA, or send/receive citrus seeds from Europe? I canít find a definitive answer online, and someone is wanting seeds sent to Moldova. Please advise.

Cold Hardy Citrus / Ichangensis froze to death, then bloomed.
« on: June 15, 2020, 06:50:17 PM »
I planted this ichangensis seedling last year to see if itís really hardy to zero degrees. Itís not. Low of 19 this past warm winter, and it and another one died to the ground. Iím a sap, so I let it shoot up from roots and the thing decides to make a flower. My seedling 80-5 did fine and Dunstan and citradia and thomasville are fine. Ichangensis out.

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
« on: November 23, 2019, 08:09:59 PM »
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?

Citrus Buy, Sell, & Trade / Wanted: citradia seeds.

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.
