Cold Hardy Citrus / Re: Crocston grapefruit
« on: May 25, 2017, 04:30:23 PM »
The original grows in Columbia,SC without protection. I cover mine with plastic sheeting and place space heater in the enclosure with thermostat device to turn on heater when below freezing. It's too cold here and stays below freezing for too long for my citrus to live and hold fruit through winter. I'd say try to ask Ben Salley or Stan Mckenzie since they have large specimens and to my knowledge only use microsprinklers when freezing over night to protect their trees.

I tasted one at Mckenzie farms in November one year and thought it pretty bitter.

These are pics of my Croxton that I harvested earlier this year. I got the tree grafted on FD from Ben Salley several years ago. I've seen the flesh pinker on one of Stan Mckenzie's fruit in November during citrus expo. I think my tree doesn't get enough heat during summer to fully ripen fruit to get pink color.

It's from a professor "Croxton " in Columbia,SC. I just looked it up on internet. Stan McKenzie talks about it on YouTube.

I have " Croxton " written in my notes fro citrus expo years ago. It's name after a Dr Croxton that lived just across the street from Ben Salley in Columbia, SC. Ben grows trees that came from the original tree at his neighbor's house.

Ben Salley of Simply Citrus in Columbia,SC. He has a site on Facebook. You can try calling Stan McKenzie out of Scranton, SC. He has a web site for McKenzie Farms and is on Facebook.

Out of all my citrange/ hybrids, the dunstan is the only one to survive last winter unscathed weather in high tunnel or totally exposed in the open, my Dunstans are full leaf now and others are at best starting to come back at base of trunk: all of these trees did well this winter, staying green in high tunnel with water barrels even after a low of 7 degrees F, until we had warm weather all February followed by low of 14 degrees and then 16 degrees the following night in late March/ early April. Ironically, the Dunstans did not have water barrels, even the one on the west end of high tunnel. My theory is that even though I vented the tunnel with doors open on both ends when above freezing, the tunnel still made it warm enough in February to break dormancy on all but the dunstan and then when the 14 degree low hit, even with the closed tunnel and water barrels, it was too much cold for trees starting to sprout new growth.  A citradia that was uncovered all winter with only a barrel for additional heat, looks better now than the bigger citradia in the tunnel. I think next year I won't use tunnel and just let the fittest survive. In the pics the green tree at end of tunnel frame is dunstan,and the losers are as followes: Ichang lemons x2, Thomasville, pink FL grapefruit seedling (totally dead), citradia, rusk, Nansho Dai Dai, mortan.

Larry, grapefruit is supposed to have anti-cancer property too. Maybe research that since grapefruit is available anywhere. Be careful if on blood thinners though since grapefruit can cause bleeding if on blood thinners.

Cold Hardy Citrus / Re: Arctic Frost Satsuma experience
« on: May 18, 2017, 06:54:09 PM »
I saw arctic frost satsumas for sale in the greenhouse of an Asheville, NC nursery, and they were covered in small thorns; my other sats don't have thorns. Is this because the arctic frosts are cuttings from seedlings instead of more mature wood, or just thorny nature of this variety?

Cold Hardy Citrus / I killed poncyrus seeds!
« on: May 18, 2017, 06:47:25 PM »
I planted poncyrus seeds in pots full of potting soil like I do anything else, and they went through the winter outside right next to potted crabapple and Rowan seeds, and now the crab and Rowan are coming up just fine and no poncyrus; the PT seeds I dug up are rotten. I've never had to make a science out of potting soil for seeds. I've grown s bunch of Ichang and dunstan seeds indoors over winter, flying dragon outside in pots, but have never got PT to sprout. Ok, y'all tell me what I did wrong.

SoCal2warm, you are like me; we always want what we can't have.

I've been having lows in upper 40's/ low 50's with highs in 60's-70's this month, high of 84 today though. My citranges and Ichang lemons have stopped growing too; actually, barely started to show any new growth. Need higher temps.

I think there is truth to node count debate. I've had dunstan citrumelo and swingle citrumelo and Changsha mandarin growing well over 10 feet tall and not bloom. Other fruit trees I've grown from seed that don't flower until 7 years old and 15 ft tall are malus angustifolia and wild apricot, and paw paw. A wild sour orange in the woods of my childhood FL home had 5 inch thorns going at least 10 ft up the length of its trunk and all fruit was 20 feet up in the top of the tree. My poncyrus trifoliata trees have been in ground from seed for over 6 years and over 10 feet high and just started blooming last year, with blooms on long branches starting at at least four feet from ground.

I'm in the mountains of NC and I'm noticing that it doesn't get warm enough here for my citrus fruit to fully ripen before freezing temps happen in late October and growth just starting now in May. Despite stopping fertilizer in August, a final flush of growth happens in September. The growth that happens in September may survive through most of winter with raised tunnel and water Barrels, but invariably, all that growth gets killed by early spring; these are trifoliate hybrids and Ichang lemons I'm talking about. I started this cold hardy citrus adventure several years ago under the assumption that some of these trees were as touted, "cold hardy to 5 degrees F, or 10-15 degrees F with some protection ". Well, they're not. The only hybrid I have that didn't lose half of its height or more the past two winters is Dunstan citrumelo. The Dunstans left unprotected all winter did better than the other hybrids in high tunnel or the citradia with only water barrel protection. The tunnel was vented on both ends when not freezing at night to help keep trees dormant. The Dunstan in high tunnel looks good now in full leaf and all others look like crap; Ichang lemons, Thomasville ( it's actually just still dormant and leafless), citradia, nansho dai dai ( looks better than citradia or Ichang), rusk, mortan. My low this winter was 7 degrees and during the 80 degree February, my citrus started to break dormancy and put on little shoots of growth wether in or outside of tunnel. When we got two nights in mid teens in march/April, my trees were cut in half wether in tunnel or not, except for 5 out of seven Dunstans. Two Dunstans that Failed are planted out in open, not protected from wind, and are under black walnut tree which maybe weakens citrus afterall, even though I'd read that citrus isn't susceptible to juglone.  Bottom line, citrus, even trashy hybrids need heat and they don't like to freeze. If you live in south central FL or a coastal microclimate that looks like FL, you can grow citrus outside; otherwise, nontropical climate folks need to invest in plastic coverings and electric heaters for any outside citrus trees.

That's a very interesting break down of bloomsweet genealogy!

Well, all I have to say is if the scientists want to GMO spinach into citrus to save the citrus species, Go For It! I doubt mixing spinach with citrus will make us sick.

Citrus General Discussion / Re: Ponderosa Lemon vs NZL
« on: April 22, 2017, 02:01:52 PM »
I've not had one since I was a kid, and I thought it was bitter (ponderosa) but so were the FL grapes that grandma grew. My other grandma ate what I now know were Nagano kumquats right off the neighbors tree, and they were NASTY! Grandpa ate bitter white grapefruit every morning too.

I think my poncyrus trifoliata fruit smells good when cut open. Similar to lilacs.

My grandma had s ponderosa lemon in FL when I was a kid. She used to put a straw in the lemon and give it to me to suck the juice out like lemonade.

Citrus General Discussion / Re: Flying Dragon and node count

Wow citrange! Your weather challenges sound like mine! We count our blessings if the trees survive freezes, high winds, droughts, fires, hail, deer, bears, voles, borers, ice storms, greenhouses collapsing under snow, etc...

Oj will get more expensive as the citrus trees die off from greening. Eventually people won't have them in yards either unless the species can be saved from greening.

I have two FD, same age, about 4 years from seed, one 2.5 ft tall, the other 2 ft talk, and neither have bloomed. I thought one might this year, but hard freeze killed most of the bloom on my PT's, so maybe the FD buds got frozen too.

Rue plant. I'm concerned about the native "toothache tree" which is in rue family and ranges from FL to Canada.

Some may be groves that were just let go by land owner. I remember seeing neglected groves as s child in FL, way before greening outbreak. Have seen apple orchards let go in NC to.

I looked up chimera and looks like it is two different species fused together. Do we call this citrandarin chimera instead of hybrid because it has a good mandarin quality fruit on a trifoliata tree, whearas most trifoliate hybrids have a tree body and fruit that is a mix or blending of the two parent trees?
