Bush2Bush, your your ideas are always welcome on this forum, as normally there is more than one right way to accomplish an objective.  I would just say what you call "industry propaganda" most people call good advice obtained through research and years of growing.

Citrus General Discussion / Re: Can you overmulch citrus in San Diego?
« on: December 15, 2017, 09:53:44 PM »
Mulching under a citrus tree is both good and bad. Clean organic material can be applied around trees for erosion control in the area of the sprinkler pattern.  Mulching 2 to 4 inches deep reduces weed growth, conserves moisture, and improves soil tilth.  Do not incorporate the mulch into the soil.  Mulch must be kept about 8 inches away from the trunk to avoid wetting the lower trunk for long periods of time.  Mulch laid against the trunk has been known to increase the infection rate of Phytophthora gummosis and other trunk diseases.  The presence of mulches on the orchard floor can interfere with heat transfer from the soil to the tree which is especially important during frost events. Recent research in a Kern County orchard during a frost episode where a thick layer of shredded orchard prunings was present on the orchard floor demonstrated that lower nighttime temperatures occurred in the mulch areas than in areas free of mulch.  Mulch free soil releases more heat to protect the tree during frost events.   All things considered if it was my citrus tree I would refrain from using mulch, and keep the soil under the tree free of all vegetation.

Citrus General Discussion / HLB In California Backyards

Citrus Greening (HLB) has been spotted in about 250 backyard trees in Southern California, but so far California’s commercial orchards have been spared. Researchers are hard at work to keep it that way.

From Marant's picture one can see why the fruit was called GRAPEfruit.  Due to the clumps of fruit on a grapefruit tree look like a bunch of grapes.

Depending on how your pruning the tree, that could be the reason the tree is not flowering.   Citrus bears flowers on new wood, and by the very act of pruning the new wood is removed.  Therefore, a pruned tree cannot flower.

Citradia, whatever fungicide you use , just be sure it is the dry powder type.

Well then SoCal2warm, your thinking is 100 percent opposite of what is written in the University of California's "Citrus Production Manual" ..It is a fantastic manual, you should buy the book.

Citradia, don't use damp paper. Here is how commercial citrus seed suppliers treat and store their seed.  Thoroughly wash the seed, then the washed seed is surface sterilized with 125-F water for 10 minutes, dipped in 1% 8-hydroxyquinoline sulfate (8-HQC fungicide), air-dried on screens in the shade, and packaged in plastic bags. When storing, it is important to leave these storage bags open initially until the seed equilibrate with the refrigeration temperature.  If the bags are closed before refrigeration, the undissipated heat and humidity may generate condensation inside the bags, which promotes fungal pathogens. Seed can be stored  at 40-F for as long as 6 months with little loss of viability.  Seed stored at room temperature looses viability quickly.   8-HQC might be difficult to find, but you can use the common Daconil fungicide which you should be able to find at any good nursery,

The variegated lemon is quite common in the USA.  The tree is very ornamental, but the variegated lemon does not produce big crops.

Welcome to the forum.  Great having you as a member.  The links to your tree's pictures did not work when I clicked on them. 

Citrus General Discussion / Must Be A Reverse Sport
« on: December 07, 2017, 03:15:32 PM »
Again this year the same branch on my Cara Cara tree is producing Washington Navel Oranges.  Last year I noticed that branch was not producing pink fleshed Cara Cara, but rather the regular orange colored fruit.  This year since the same branch is once again producing fruit with  orange colored flesh that branch must have surely revered back to a Washington navel.   For those that don't know, Cara Cara were originally a sport of a Washington Navel orange tree growing in Venezuela.

Most companies that sell citrus seed, sell only seeds of rootstock varieties.  Minimum order is usuall aroung 100 seeds and up.  As an example look at LYN seed web site.

Many plants need polinators, but of course Citrus trees do not---neither does tomatoes nor pineapples as they are self polinating.

Mark, I actually have a Saint Dominic Sour Orange tree planted from seed. When it was large enough the tree was transplanted into in a large bottomless Root Maker container.  It has been growing in the container for 5 or 6 years and has long ago rooted into the ground.  The tree is doing fine with nice fruit on it.

that transmits citrus greening disease, a development expected to help farmers control a plague that has destroyed trees in growing regions of Brazil and the United States.

The scientific breakthrough, shared with Reuters exclusively on Tuesday, is the result of six years of research on Diaphorina citri, the vector of citrus greening disease.

The molecule was discovered by Fundo de Defesa da Citricultura (Fundecitrus), a research center sponsored by farmers and orange juice producers in Brazil, in partnership with the University of California, Davis and the University of Sao Paulo's Agricultural College, known as Esalq.

The next step will be to synthesize the pheromone from the molecule and create a product that will work as a kind of trap to attract and neutralize the insect. Then scientists hope to reduce the spread of a disease that resulted, since 2005, in the destruction of almost half of Brazil's current orange tree area.

"This will not cure greening disease, but it will allow us to work in an intelligent and assertive way against the insect," Juliano Ayres, general manager at Fundecitrus, said in a telephone interview.

The first commercial solution should be available to farmers in a year, said Walter Leal, the Brazilian researcher representing UC Davis who participated in the interview.

Sky Valley HEIRLOOM Navel Oranges season is beginning. The limited offering of this premium citrus will begin shipping next week, and is expected to last into March. The older a citrus tree gets, generally the better tasting citrus they produce. The limited crop of this heirloom variety was originally PLANTED IN THE 1930s, (trees are now 85 years old) and is now harvested from a single ranch for the duration of the season, ensuring consistent flavor and quality. Sky Valley Heirloom Navel Oranges TRULY represent quality over quantity and are unmatched in the citrus category as the only citrus grower that supplies heirloom navels from a single ranch, meaning retailers never have to worry about mixed results during the season; Sky Valley Heirloom Navels taste as great at the end of the season as they do at the beginning.

The reason for big citrus trees a hundred years ago was because they were started from seed back then.  A seed grown tree already had some size to it before it matured and begun producing fruit.

I've seen  quite a few citrus trees in Charleston.  Lazz has four or five citrus trees growing outside at his home in North Charleston.  There is a lady with a large grapefruit tree in her back yard in Charleston that I know of, and Citrus Joe and I picked mandarins off of another tree in Charleston.    SouthCal2warm, I don't think growing a tree on it own roots, instead of various other rootstocks, necessarily makes a citrus more cold hardy.. 

Citrus General Discussion / How Many Trees Per Acre Needed To Make A Profit
« on: December 04, 2017, 09:23:37 PM »
At economic seminar on Nov. 30 agreed that low-density citrus plantings would likely be hazardous to growers’ financial health in the face of HLB. One also reported that the average grower is not making a profit, and that small growers are exiting the industry faster than larger growers. “We were looking into different tree densities: 145 trees to the acre, 220 trees to the acre and 303 trees to the acre,” says Ariel Singerman, economist with the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS). “We considered different scenarios for yield: low and high, and different scenarios for prices: low, medium and high. And basically what we found is that you don’t make any money when you have 145 trees to the acre and you have a low-yield scenario” which the U.S. Department of Agriculture’s National Agricultural Statistics Service reports is the average in Florida groves. “You need to have at least 15 percent over that (average yield), and even then you have a modest return” with 145 trees per acre, Singerman says. Even at 220 and 303 trees per acre, it takes a while for growers to break even on their investments, under Singerman’s economic analysis. “Even the best-case scenario takes about 10 years just to bre ak even,” Singerman says. The economist acknowledges that many growers are uncertain they can get 10 years of production out of a tree in the face of HLB.  Economist Tom Spreen, UF/IFAS professor emeritus, agreed with Singerman that growers can’t be profitable planting 145 trees per acre. He said growers likely need to plant more than 200 trees to the acre to be profitable. Singerman says Florida citrus growers now are losing money, on average. “If we take the average yield for the state and the average price of (oranges) … the grower is not making money currently and has not been making money for the past few seasons,” he says.

Manure is not a good fertilizer source for container plants, due to the higher levels of soluble salts.  The quickest method of growth, that I know of is give additional light to the tree from sunset to 10:00 PM, and keep the root zone at 80-F. Re-pot the tree into a new container before the tree's roots become root bound. A tree can be re-potted as soon as the roots are able to hold onto the soil when the tree is removed from the container.  Fertilize with a fertilizer as close to a 5-1-3 nutrient ratio plus the trace elements.   Be sure the tree is growing in a well draining medium.  Good luck to you and to this tree.

Is this tree going to be grown in a container or in the ground?

Luak, the urea that I buy is a granular product.  You can use pelleted urea if it dissolve in water.   The Tween 20-surfactant is added directly into the urea spray solution at 1.5 teaspoons per gallon..  Whatever urea you use be sure it is low biuret urea.
