Bonsai. When cultivating bonsai using fruit bearing trees such as citrus or crabapples, one usually uses a little deeper pot to provide a little more nutritional support from a larger root mass. Need good drainage, regular watering, and adequate fertilizer to keep up with the frequent watering.

Iím harvesting my Rio Reds and Croxton grapefruit now too. They have to be on tree almost a year and a half to ripen here too.

I cut open three fruit this morning. All were mostly pith and desicated. I agree with SoCal2warm: tree too small. My Rio Red made small pithy fruit the first few years, now the fruit is much better. Fruit may have frozen and dried out when it went to 14 degrees two nights in March. Even with space heater inside portable greenhouses, I didnít have a 32 gallon water barrel in this one or my bergamot or shiranui, and the bergamot and shiranui almost died from that late freeze. They did well the previous winter, but this warmer winter followed by a hard freeze shocked them too much I guess, even though they were not showing signs of active growth yet.

I donít think I have a lack of cold weather problem here in western NC. Iím going to cut open some fruit and assess further.

Why would my 5 ft tall Seville sour orange tree have fruit that wonít ripen after a year and a half? Grew great last year and blooming great this spring.

Iím giving up on my from-seed papedas which die back every year from cold. I have/had two left that went unprotected this winter and kept green leaves all winter which was unusually warm, and pretty much died after two nights of 14 degrees in mid March. Cold hardy citrus is only hardy while dormant. Two weeks with temps in seventies and sixties followed by a polar plunge kills. Even my citranges look like garbage right now and my 15 foot tall Changsha unprotected this winter looks like a dry tumble weed although still green for now when scratch bark.

Thanks. Iím trying to hit open flowers with paint brush but nothing seems to stick to it. My paw paw pollen sticks to paint brush easily like yellow dust. I donít feel confident about the citrus pollination.

I donít know about plastic envelope. From what I read it only mentions drying it out so itís not wet and freezing it. Seems it would mold or be too wet in plastic. Some talk about putting it in glass tubes. I just donít know. Three weeks sounds good though. Just need a few days.

Citrus General Discussion / Pollen collection and storage
« on: April 18, 2022, 10:08:16 AM »
Iím collecting pollen from poncirus and put it in a paper envelope. I need it to pollinate an orange tree with flowers with white unopened buds that may open in a few days. Iíve read about drying out pollen and then freezing it to use months later. Can my pollen stay viable in an envelope for a week or two without having to freeze it? How do I know when to strip petals off of unopened blossoms to access a mature pistil?

Cold Hardy Citrus / Re: Poncirus perfect flowers vs. staminate flowers
« on: April 15, 2022, 08:57:15 PM »
A lot, actually most of my poncirus flower buds froze off this spring thanks to a warm winter followed by a fabulous two days of 14 degrees F in mid March. Anyway, I was outside today trying to extract pollen from the few flowers that are showing up. I noticed that some flowers only have stunted stamens inside and some only have pistils. A few had perfect flowers with nice yellow pollen on stamens.

My poncirus often bloom before my other citrus varieties and the blooms canít withstand a freeze. Some years I donít get poncirus fruit.

Know that Woodlanders sells seedlings. Ichangensis does not always come true from seed so probably a hybrid. I have seedlings from a fruit I got from Woodlanders and from another place and the main leaves are a little longer than petiole at least most are.

Cold Hardy Citrus / Re: Georgia Grower Rapidly Reacts to HLB Find
« on: February 23, 2022, 10:19:42 PM »
I just learned from a commercial grower in south GA ( actually, I believe she was the author of this article) at our annual southeastern citrus expo last November that they have now determined that the psyllid  is not killed by cold temperatures and that they are found hiding under the leaves even during freezing temperatures. They are bagging the trees there to give protection from psyllids  and for additional freeze protection. At one point they said you would have to be somewhere where it stays below freezing for three days or more to kill the psyllid. This past winter, we didnít even stay below freezing for a 24 hour period here in western NC. Global warming is going to bring the bugs further north. They also say hurricanes can blow them north too.

Iíve seen a lot of my cold hardy citrus die when the bark at the base splits like this. It splits on the south side of the tree in spring after temps have risen enough to cause sap to flow and break dormancy, followed by a freeze that splits the bark. The trees need to stay cold and dormant as long as possible throughout fall, winter, spring. Some blooming and growing in winter even in the greenhouse is a problem since temperatures will drop below freezing in the greenhouse even with supplemental heating when outside temperatures get cold enough. Signs of new growth in March is a bad sign here.

My Chandler is a new grafted potted whip. Just got it this fall. Hasnít bloomed or fruited yet.

The few citrus that I have overwintered in my house have not grown during winter although it is warm indoors and they were in a south window. As they got bigger and pots got heavier I got really aggravated every time I had to cart them in and out of the house spilling dirt and water on my carpeted floor. They go out once a week if possible to get hosed off for spider mites control, etc. So, this winter I decided to take a chance and just stash those not-so-cold-hardy potted varieties outside in a portable greenhouse with a couple of water barrels and two small space heaters inside, and they are doing just fine. Still not growing, but not frost damaged and no spider mites, and no dirt spilled on my floors. So far this warm winter my low has been 13 degrees F. My potted varieties are Santa Teresa lemon, Chandler pomelo, and Lakeland limequat.

If added sugar is undesirable, Sure Jell makes a pectin additive that is made for without adding sugar. Iíve always done the old fashioned sugar recipe because after all the prep work of making the jelly, I donít want to take a chance of it not setting or being preserved. I know sugar is a natural preservative. To each their own.

It says on the Sure Jell instructions. 1000 to 3,000 feet adds 5 minutes. From 3,001 to 6,000 ft add 10 minutes.

I donít know about all that temperature and pump stuff, but I have made a lot of marmalade using primarily the Sure Jell recipe, and modified some if poncirus marmalade to process out resins. I have to add 5 minutes to my canning time since I am at 3,000 ft elevation.

If Ichang lemon isnít sour enough, try citremon. It will be more cold hardy too. I like swingle citrumelo as a lemon substitute too.

Cold Hardy Citrus / Re: Carolina lime questions
« on: February 08, 2022, 07:53:09 PM »

I got a Carolina lime fruit from Stan McKenzie. It tastes like lime and is actually good although it is a trifoliate hybrid. I believe Stan says it is an unknown variety that originated in Europe. He calls it Carolina lime since it is otherwise unnamed.

Spray trees down with water hose and/ or neem oil solution once a week to deter spider mites if trees indoors in winter.

Citrus General Discussion / Re: Triple Superphosphate question.
« on: January 31, 2022, 09:02:48 PM »
You should get a soil test done. I had trouble getting my apples to bloom for years, after a soil test learned that the mountains of NC tend to be deficient in phosphorus. I now plant everything with some triple phosphate and everything blooms well now. Too much phosphorus in fertilizer is supposed to be bad for fish in rivers so only use phosphorus if you need it in your specific location.

Cold Hardy Citrus / Re: Citrus soil mix for pots
« on: January 24, 2022, 09:38:20 PM »
I tried the 5:1:1 mix but it was too aggravating to figure out what kind of pine bark mulch to buy, and I donít want to do the sifting out the smaller pieces of bark thing. I like mixing the Turface with the Miracle Grow Garden soil. So much easier. I tried some kind of pumice stone mixed in potting soil but it was very heavy and did not drain nearly as well as the Turface. The pumice stone gravel stuff is meant to mix into garden to deter voles; I think it was Sunshine brand or something. Came in a white bag with a sun on it. Cheaper than Turface but I donít like it.

Iím glad I read this thread. I planted a shiranui this year but since it is mandarin, I assumed it would ripen when my other satsumas and Changsha mandarin ripen in late November and December. So, I should wait until January or February for my shiranui fruit, huh?
