Nice...a lemon?
We're living in Mexico and confusion reigns concerning what name to attach to which citrus fruit. Common names go only so far, and, when the young folk at the various nurseries sell us 'named' trees...and three years later they are fruiting different 'named' fruit...confusion reigns.
Does anyone know of a pictographic webpage that shows and compares citrus types?
All is not lost here, as we were harvesting about 200 lemons off our 3 year old grafted tree a couple months ago. Lemon is not a popular citrus here and we had to order the grafted tree (lemon on top of a hardy lime root)
Thanks for input.

We've been having some discussions in other scattered threads about making your own nutrient mix for citrus. This looked like the best place to consolidate it.
Anyway, the hot topic has been "how to mix natural sources of plant nutrients for citrus?". The answer is: there are many ways to do it, but ultimately the goal is to have the N, P, and K in ratios of 3 to 1 to 2 -- with respect to each other.
Since we are also having this discussion with regard to tomatoes, I have created an excel spreadsheet that might help you make decisions on fertilizer mixes for citrus and other fruiting plants. Well see :)
Here's a link to the spreadsheet: N-P-K_Mix_Analysis_v02.xls (http://www.plantsthatproduce.com/guides/N-P-K_Mix_Analysis_v02.xls)

Make sure that there is 3 to 5 inches of 1-inch diameter mulch on top of the soil surface so that the soil surface does not completely dry out. The mulch should extend past the "drip line" of the tree canopy.
Contact A&L Laboratories West (http://www.al-labs-west.com/). Get the materials from them for a soil analysis and send them the sample. The will send you a PDF file with the analysis -- send it too me when we get it and then we can talk about it here or in private if you like.

I find peppers & tomatoes to root with ease in the AG, but blueberries or other cold weather plants tend to fail in the AG very quickly.

For citrus rootings, use semi-ripe cuttings in midsummer.

Some folks asked for dosage information in the spreadsheet, so added that and called it: N-P-K_Mix_Analysis_v02.xls (http://www.plantsthatproduce.com/guides/N-P-K_Mix_Analysis_v02.xls).
As an example, you can get the citrus ratios of 3:1:2 by mixing:
4 lbs Blood Meal (steer)
1.1 lbs Bone Meal
0.7 lbs Potassium Sulfate
For a citrus plant outdoors in a 15 gallon pot, the maximum annual dosage would be about 0.8 lbs, which you could divide up into monthly or trimester feedings.
Keep in mind that this only covers the N, P, K ... there will be follow-on posts about obtain the minors, micros, and hormone ratios for citrus and other near tropicals.

The classic book on pruning "How to prune fruit trees" by R. Sanford Martin basically says you don't need to prune young citrus trees. Remove dead wood, crossing limbs, and suckers. If that leaves you with a shape you don't like, shape it as you wish. What happens in the lemon orchards around my house is that tall growth gets removed to keep fruit in reach and the centers get opened to let in light.
In short, prune it if you want to, but it probably isn't necessary.

Great answer. Citrus bark is sensitive to sunlight, and as a wonderful consequence they naturally form a "ball" shape. If you do want to control some wayward branch, follow the pruning mantra "thin, don't trim".

What a great article.
Although most citrus fruits contain polyembryonic seed, they also contain monoembryonic seeds in characteristic locations. If you want to grow citrus from seed and be true to type, check a seed or two from each area of seed formation. Generally, the polyembryonic seeds are fatter.
You might have trouble locating seeds in navel oranges. :)

Yes, that great scent really travels. We have a small orange orchard on our campus and you can smell the flowers hundreds of yards away if you are downwind. A nice way to take your mind off work for a few moments.

The scent of Citrus in bloom is one of my favorites. As a child my home in Redlands CA was in the middle of 200 square miles of citrus orchards. Nowadays the orchards have mostly been planted over with houses, there are about 15 square miles of Citrus remaining in the Mentone area.

Same as you would choose for growing in the ground, but grafted on a non-aggressive (so-called dwarfing) rootstock.

Semi-hardwood cuttings from Citrus are easy to root. Trifoliate rootstock is often propagated by cutting.
Grafting onto 2-3 year-old seedlings works great too.

When pruning to open up the center of a tree it is good to leave growth that sprouts on the main scaffold branches for shading the bark. But trim those to 6 inches or the tree center will just fill up again.
I saw first hand the results of this practice when my rare fruit tree club had a tour of Premier Grove orchards in Ft Pierce this year. Three hundred acres of cancerized citrus were converted to low chill Florida peach production. Saw the packing house and one of the chilling rooms -- everything very professional.
Now I understand stuff like why the main trunk on young trees is pruned to 30" for some varieties and 15" for others. Growing the main scaffolds low to the ground controls tree height. Varieties like Tropic Beauty that tend to grow more upright need the shorter trim.

I have lots of citrus in bloom right now. I need to make a list of the varieties I've got. Most are separate trees but a few are grafted onto other trees. Many are still in pots (I grafted/budded them myself after obtaining certified budwood from CCPP) but will go in the ground soon. I'm going to start a list now and will add to it as I go out and check around and find things I'm sure to miss....
Two navel oranges dating from the 1970s which are of two unknown varieties. I picked about 800 pounds of citrus from them this year, like most years. I still have about 20 pounds 40 pounds of very ripe fruit on the tree which I'm eating daily. The trees are in full bloom with a great scent reaching 100 feet away or more.
An unknown variety of lemon of about the same age. I pick maybe 200-300 pounds of lemons a year. Most of the crop is still on it.
An Oroblanco - I don't eat it due to effects on statin (cholesterol medication) I take :( I picked about 200 pounds for sale to the fruit stand (which buys most of the above fruit)
These are younger and just coming into production:
Valencia
Gold Nugget
Tango
Kishu
Tahoe Gold
Miyagawa Satsuma
In Pots:
Centennial kumquat
Nordman Seedless kumquat
Page (mandarin/tangelo or whatever)
Clementine de Nules
Fremont mandarin
SRA 92 clementine mandarin
Xie Shan satsuma
88-2 mandarin
Caffin clementine (perhaps the prettiest of all citrus when full grown, IMO)
USDA 15-150 mandarin
Wow, the other day I told somebody that maybe I had 15 citrus. I just counted 10 varieties in ground, 10 more varieties in pots (14 plants with some duplicates)...
Grafts onto some of the first three:
Smith Red Valencia
Midknight Valencia
Palestine sweet lime
Buddha's Hand citron
I still hope to get Dekopon some day, but might be about done otherwise.
For what it's worth, I've not found a pigmented citrus that I really like enough to justify planting. I've tasted the same fruits that others have raved over (i.e., at Lindcove tasting) and I just don't get it. Bland.
I usually don't fertilize my citrus as they are productive enough without it. I have been pruning my large navels to make it easier to access them with picking ladders. And I prune my lemon tree as it gets too tall and was planted by prior occupant too close to the house.
Oh yeah, one more that I might get some time is Ortanique tangor. I tried grafting it once with wood from CCPP but that wood was too immature, IMO. Toots Bier had highly recommended it for juicing over any Valencia (for California conditions, at least)
blah blah blah
One more thing....Mitchel, you said you had a "Paige". If you mean Page, I think you'll need a pollinator if you don't already have one or you can spray with giberrillic acid (GA3), especially if you don't want seedy fruit.

It isn't on the list I found on CDFA's site but I and some others found that it is affected by HLB (not surprising) but also found that Asian Citrus Psyllid avoids the tree. If we get the African Citrus Psyllid here then they will be subject to infection.

Not much to go on here, but I found citrus psyllid (African) (Trioza erytreae) (http://www.plantwise.org/?dsid=54914&loadmodule=plantwisedatasheet&page=4270&site=234) which specifically mentions Casimiroa edulis as being a host for the African Citrus Psyllid and within that page makes mention that the significance is that it's a vector for HLB.
A couple of studies which indicate Casimiroa is not a host for Asian Citrus Psyllid are http://www.senasica.gob.mx/includes/asp/download.asp?iddocumento=18380&idurl=27167 and a spread sheet with various HLB related studies, "Liberibacter publication list (2000-2011) (Excel)"
http://citrusgreening.org/Liberibacter%20publication%20list.xls
I don't know of any studies where they have attempted to infect Casimiroa manually so it's probably safe from infection here in the US unless the Asian Citrus Psyllid is introduced as well.
Richard
04-22-2012, 10:49 PM
When the ACP program started, I inquired with my inspector and then the local program director if the Casimiroa should be on the list. They checked and reported the negative result in the Florida program. The 2012 list from CA represents updated studies done by the Citrus research program. I'll check with them to see if Casimiroa was tested again.
Some readers might be unaware: Casimiroa (White Sapote) is a western Hemisphere member of the Rutaceae (Citrus) family in the Linnean taxonomy system. However, in genetic classification they are placed in different subfamilies (Toddalioideae vs. Aurantioideae).
harveyc
04-22-2012, 11:55 PM
I don't have any reason to believe Casimiroa is a host for the Asian Citrus Psyllid but it looks like it might be for HLB. From what I can tell, the testing done in the U.S. is with Asian Citrus Psyllid without directly inoculating plants with HLB.
One concern I have is that if Casimiroa was infected somewhere in SoCal that seeds of fruits produced from those trees might make their way up into NorCal and get planted since several of us up here have done this in the past. Still, it's such a rare species up here my level of concern is quite low. It's just something I'm keeping in the back of my head (figuratively).

I'm going to try this method of posting photos for a while. Taken with my phone and uploaded to Google+. Not a great shot but a lot faster than me processing large files from my DSLR and processing them in Lightroom, etc. and then uploading those to my own host.
I began harvesting my navel oranges maybe a couple of months ago, maybe two and a half months ago, and they are about gone. I picked about 800 pounds between this tree and a smaller one, not counting another 200 pounds or so that dropped to the ground. They are very tasty but breaking down quickly now. The tree is in full bloom as can be seen in this photo. This tree has an old volunteer (?) avocado growing up through it to which I've grafted an unnamed seedling selection picked up for me by Tony.

From what I have read and heard the Psyllids don't like Casimiroa, if you give them no choice they will use it as food, but they don't reproduce on it. If they don't feed on it they can't transmit it. I haven't seen any reports of White Sapote having HLB.

The Asian Citrus Psyllids don't like it but the African Citrus Psyllids do, from what I posted above. Fortunately, we don't have the African ones in the U.S., as far as I know.

So far, my understanding is that:
HLB (the Citrus Greening Disease virus) affects certain members of the Rutaceae family, especially those in subfamily Aurantioideae.
Being a member of the Rutaceae family is not a precondition for HLB susceptibility.
There are only a few known vectors (carriers) of HLB.
There are many host plants for the vectors. Most recently edible figs have been added (see 3435 Asian Citrus Psyllid -- State Interior Quarantine (http://pi.cdfa.ca.gov/pqm/manual/htm/420.htm)).
Being a host plant is not a precondition of HLB susceptibility.
There is no report from a plant pathologist of a Casimoroa being infected with HLB.
Corrections are welcome!

Just to throw my hat into this thread. I have three in-ground citrus trees here in South Ga. A Meyer's lemon which I got nearly 300 lemons last year, a Brown select Satsuma in its third year and a newly planted Red Navel.

So far, my understanding is that:
HLB (the Citrus Greening Disease virus) affects certain members of the Rutaceae family, especially those in subfamily Aurantioideae.
Being a member of the Rutaceae family is not a precondition for HLB susceptibility.
There are only a few known vectors (carriers) of HLB.
There are many host plants for the vectors. Most recently edible figs have been added (see 3435 Asian Citrus Psyllid -- State Interior Quarantine (http://pi.cdfa.ca.gov/pqm/manual/htm/420.htm)).
Being a host plant is not a precondition of HLB susceptibility.

Thanks for putting that clearly; that is my understanding as well. I believe Casimiroa might be susceptible to HLB from the link I provided, but I don't believe it's been tested (only evaluated as a host for Asian Citrus Psyllid). Is that your understanding re: Casimiroa testing as well?

I believe Casimiroa might be susceptible to HLB from the link I provided, but I don't believe it's been tested (only evaluated as a host for Asian Citrus Psyllid).
The link you provided is to an information page provided by CABI (http://www.cabi.org/default.aspx?site=170&page=999). Regardless of their proclaimation that they are "an international development-led organization", they are in fact a publishing company that supplies grants to university professors throughout the world in exchange for information. The content on their site has been produced by their marketing and web team. If you go to the Meet Our People (http://www.cabi.org/default.aspx?site=170&page=1519) page and select the "Pests & Diseases" keyword search, then follow-up on those people at their institutions it all becomes clear. So the best I can say about their web sites is that the content appears incomplete.
Is that your understanding re: Casimiroa testing as well?
Yes. Early on in my participation in the ACP program I pressed hard to find out if Casimiroa was at risk -- not only because I sell them but especially since I have a prize tree in my front yard. I am still interested in the topic because there are massive testing programs for HLB hosts and carriers (plant and animal) in progress and new information is coming out monthly.

I recently received this Reeds Dwarf Orange Citrus Tree from an 84 year old neighbor.
The tree is at least 15 years old and it has never bloomed .
The reason its never bloomed is my friend just wheeled it in his shed in the fall to overwinter never giving it a chance to bloom naturally....... go figure it is still alive. I know you folks who grow citrus like to see a flower ,however I cannot provide you one for a good id.
The tree was purchased at an exit near Tampa,Florida U.S.A.
I have the original orange and green box instructions .
My question is what variety of orange might this be????
Also how can I force this to bloom for my friend.
The tree is in great health

That tree may need a cross pollinator. I know I've fed my grapefruit and oranges fish 5-1-1 and it gets them to bloom, my nectarine (has blooms on it now) and a friends keifer pear is full of blooms again after they already have gotten fruit off it this year. :^)

down here in Mexico, the locals drive a nail or a wood stake into the offending tree...and they believe it. I have a few non-producers and a handfull of nails...stay tuned!

All driving nails will do is put holes in your trunk for disease to enter. It will not help your tree. Please do not do this!

Any other good ideas which might help me ?
I am more interested on the cultivar .....A Guess perhaps?
Toss out a name .
I need to start somewhere.
I will do the research.

Darkman,
We have no winter here...only superstition.
It's Mexico, and southern at that.

cincinnana,
Does your friend prune his tree often? Citrus must reach a certain node count before they flower. You can consider each new leaf as another node. The problem is that if your tree grows to node 100, for example, and you prune it back to node 50, then the tree must start growing again at node 50. Pretend you need to reach node 300 for the plant to flower. If you keep pruning the tree back, then it will never reach its required node count, hence it will never flower. I cannot tell you a definite node count for your tree or any tree. If the tree is grafted, the scion stock may have already reached the required node count, so your tree may be capable of flowering. However, since the tree has not flowered in the past, it probably has not reached its required node count.
I have citrus trees also. I usually have to bring them inside during the 1st or 2nd week of November and throughout the winter. About 2-4 weeks after I bring them in, they flower. I have to pollinate my citrus throughout the winter if I want fruit. It is my understanding that stress induces flowering in citrus--for instance, a dry period or a sudden change of environment. Is it possible that your friend's tree does flower when he throws it in the shed, but no bees or a person is around to pollinate it? Then the flowers would just dry up and he would never see fruit. My citrus do not flower during the spring or summer when the bees are around to pollinate.

We need a close up of the leaves, this photo is too far away, and something for scale. Even then, a lot of citrus look similar.
