Citrus General Discussion / Re: Growing oranges in FL
« on: July 22, 2024, 12:40:46 PM »
UF/IFAS has developed a few varieties that are recommended for the home landscape. These include:

Sugar Belle®- a rich-flavored, delicious mandarin with first harvest in mid-November to late December; HLB-tolerant

Marathon mandarin -- fruit matures early and is attractive; peels fairly easily; seedless, not messy and great flavor; HLB-tolerant

There is also a tree that was discovered in an orchard without symptoms and is being propagated with great excitement, don't know the name and an internet search is not yielding results.

There were 11 seedlings.  They vary in vigor.  Not all of them have bloomed yet, they are about 8 years old.  The plant with with this purple flower has died.  Flavor among them is generally sour with some bitterness and decent brix, one of them tastes good enough to sample twice.  Another tree has flowers with long curling petals and very shiny leaves.  They survived 8 degrees F a few years ago.  F2 seedlings are years away from flowering.

Dig a hole next to a plant to check for soil moisture.  You don't know if there is too much or too little moisture unless you look.  Chicken manure is extremely high in nitrogen and can easily burn your tree.  Something like Osmocote plus is a better choice as it releases fertilizer slowly.  Protect your plants from full sun until they are larger.

On a  side note, it was under low  water  and  very hot temperatures outside.

Is  this  normal or just rare genetics?  What can  I  expect from this plant?
Severe stress will cause citrus to bloom

The AI program Perplexity provided this:
Yes, there are a few olive tree varieties that can potentially thrive in USDA Zone 7, though they will require some extra care and protection during cold winters. Based on the search results: The Mission olive tree is considered one of the hardiest, able to tolerate temperatures down to around 20°F (-7°C). As one of the oldest American olive varieties developed in California, it is well-suited for the west coast climate including Zone 7. The Frantoio olive tree from Italy is rated as very cold-hardy, tolerating temperatures down to around 10°F (-12°C). It is recommended for growing in the Pacific Northwest which includes parts of Zone 7. The Arroniz olive variety from Spain has a very high cold tolerance rating of 5 out of 5, potentially able to withstand temperatures below 0°F (-18°C). This makes it a good candidate for Zone 7 climates. The Chemlali olive tree from Tunisia is described as more cold hardy than most, tolerating Zone 7 temperatures. Its compact size also makes it suitable for smaller yards. While not ideal, the Arbequina olive can sometimes survive in Zone 7 if given extra protection like planting near a warm south or west-facing wall. But it may suffer damage in extremely cold winters. So in summary, while olive trees prefer warmer climates, with proper varietal selection like Mission, Frantoio, Arroniz or Chemlali, and by providing warm microclimate conditions, it is possible to grow olives in the cooler Zone 7 regions.

I did not know where to post this since it is not citrus but thought you all are growing cold hardy stuff so thought you might have info on cold hardy olives. I know alot of people that plant Arbequina but I don't think it will make it in zone 7. So is anyone growing olives in zone 7 and what kinds do you all recommend?
Arbequina is not hardy, wish someone in the US had this.
Variety found in the Lodévois basin. It is the only olive tree capable of withstanding – 25°C in adulthood . Medium vigor olive tree. Ball-shaped habit, sometimes semi-erect. Medium fruit, sometimes large, flattened at both ends.

I thought the flavor was as good as store bought fruit.  The problem is getting the tree to produce fruit.  I am still struggling to get one fruit.  An advantage of growing citrus outside of the usual areas is that you will not need pesticides.  An Owari grown outside of the citrus zone has blemish free fruit without pesticides. 

Virginia Fruit Grower on his channel discussed the problem of lack of fruit with Stan.

Did you do anything to speed up flowering?

Meiwa did not fare well in a coastal South Carolina trial.  It is probably less hardy than other kumquats.

At the Southeastern Citrus Expo two years ago there was a presentation on this topic.  Citrus do well in the shade, but much less yield.  Also less attractive to psyllid.

Thank you. Are they completely seedless?
I think they have a few seeds, but could be mistaken.

Does anyone know more about this plant's background?
What  do you think of their other Frosts? Do you have them?
I have them but not growing in the best of conditions so no fruit last year.  The grapefruit is delicious.  The lemon tastes like a lemon.  The satsuma was good.

I have a question for you on this cross:

"Pummelo Siamese acidless x Poncirus (fast flowering or Poncirus+)"

I want to use the Banpeiyu for my pomelo since I have a large tree with fruits now so I can do it on the next flower cycle.

Which fruit do I get the pollen from, and which fruit will should be the female to hold the fruit?
Pummelo has mostly seeds from sexual crosses.  It would be the female parent.

This week Precocious Poncirus flowers collected for their pollen were sitting in a small bowl and a faint fragrance came off of them.  First time I have noticed any odor.

Juvenile citrus plants frequently have thorns that do not persist in the mature fruiting plant, so your plant may eventually be thornless as an adult.

3-3 usually sets fruit, but my 2-2 has never bloomed, so it needs more attention apparently.  2-2 is hardier by at least a couple of degrees.  From sampling 2-2 a long time ago, and the 3-3 more recently, 2-2 had more flavor.

I put 4 citrus and one olive tree in the ground last spring. I have been researching for about 2 years on how to get them to survive a winter by using 100 watts of electricity (a string of Christmas LIghts) along with plastic, styrofoam and wood chips. I am actually having a problem with them being to warm. Last night it was 16 degrees and inside my set up it was 62 you look at my photo the trees are actually 2 feet below the level of the plastic. i planted them 1 foot below ground level and added 1 foot of wood chips. At 10 cents a kilowatt lights are running at 100 watts an hour.  So basically 1 cent an hour to heat my setup

This may help:

Thank you sir! I'm so happy that recordings of the presentations are now being made. I have been 2 of these, and I was always annoyed when I missed one because I was late or speaking to other attendees...
It great to be able to go back and find out what I missed the first time.

Does anyone know where the information about seed grafting method is located?

On the old forum there was a topic about grafting a sprouted seed onto a rootstock.
