Aw, I'm still in 9a.

 I heard that many years ago it used to be a lot warmer here and they used to grow a lot of citrus commercially. Anyone know what zone Jacksonville was like 20-30 years ago?

Was it 20-30 years ago that they used to grow it? I remember reading in a book about the History of Citrus that a while back (I think even more than 100 years ago) there were many citrus groves further north in the state because there hadn't been a strong freeze in a few years. After many people planted out acres of citrus and the trees were doing well, a really strong freeze happened and killed off all the groves that were too far north. The groves were not replanted in fear of losing everything again. Since I do not have the book, what I said is just from memory and could be completely wrong. I will try google and see if I can find more concrete info about it.

Murahilin, curious as to why it's so important to you where Julie mango originated? Ok, let us know when you find conclusive evidence.
From the little research i've done i think it's hard to find such conclusive evidence, as plant material was carried freely between places and back again. Because mangos in Reunion have some DNA similarity doesn't necessarily mean they originated there. May just mean some of its parentage may have come from there. I don't think DNA alone can conclusively prove parentage, only relationship. You still need historical records + DNA thumbprints.
I suppose it's possible that mango seeds traveled from Africa during times of slave trade to Jamaica. But Reunion is off the wrong coast. So Julie would have to have been dispersed through Africa towards west coast to have been carried to Jamaica.

Oscar,
My only reason is because I hate the idea of not knowing. There has to be an answer, and I am sure there is record of it somewhere. I don't know if I will ever find conclusive evidence, but I will continue to search.
I agree that it may not have originated in Reunion, but that one source from the 1960's saying that it did is interesting. I am going to try and get in contact with the author of that article (I was told he is still alive) and see if he remembers why he thinks that Julie originated in Reunion.
I doubt it came through Africa though for the same reasons you mentioned. I think it is more likely that the Julie or its ancestor mangos went directly from Reunion to one of the French Caribbean Islands and then either the Julie grew there or the Julie's ancestors further spread into the Caribbean and finally created the Julie in Trinidad. I haven't found any evidence supporting Jamaica as the origin yet though. Everything seems to point to either Trinidad or Reunion.

Another interesting side note, Trinidad had a fruiting mangosteen in 1875.

Trinidad?

The Republic of Trinidad and Tobago. Quite possibly the greatest island(s) of the entire Caribbean!

Just saw this: http://planthardiness.ars.usda.gov/PHZMweb/default.aspx

thanks! now I need to change my profile! i'm in zone 9b i guess...what's the zone map from 1955 look like??? lol

Here is Bloomberg article on the new zones
USDA ‘Plant Hardiness’ Map Shifts Temperature Zones North http://www.bloomberg.com/news/2012-01-25/usda-plant-hardiness-map-shifts-temperature-zones-north-1-.html Not that I believe it. Lots of this global warming hysteria has been exposed as junk science as far as I'm concerned.  It is beyond laughable to classify CO2 as a pollutant. Water vapor is a stronger factor than CO2 in the greenhouse effect. Solar cycles are very influential.

Zands... be nice  You know us liberals get hurt when someone talks bad about global warming!

It was an experimental feature that we decided to remove because some people were "smiting" others too much. Patrick and I, as Admins, can see everything relating the karma and certain people were smiting too much which we felt did not coincide with the happy helpful forum we wished to have. If there was only a way to give people positive karma, we would have kept the feature. I can give you an honorary title other than "member" for you all your troubles if you'd like?

A03 'Graham' mango description

It's from Trinidad so it must be good.

it's overkill is what it is.  i'm not writing a research paper on a forum, so not everything has to be nice and neat.

Your subject simply said "fertilizer". I thought that was too broad because it did not say what about "fertilizer". It makes it easier for people to read the forum and pick what topics they open with more descriptive subjects.

depending on your location I can get you a seedling to trade, or maybe for free if I have seed...this variety is patented so I can't sell  so you get for free or trade from me! but could be a bit different due to pollination I've heard....

Which variety are you saying is patented? The TR Hovey?

I don't have any scientific instruments 

I have been looking on Amazon for the refractometers though because they have a very wide selection and the reviews are usually pretty helpful.

If I remember correctly, the newer growth is wider and does not have as many ripples on the leaves. I think the growing conditions in the container may cause been the cause of the leaf differences. I guess I will see if it is a Lemon Zest soon enough. I got it from a row of 15g LZ's at Excalibur.

I do not have an updated pic of the entire tree but I do have a pic of the day I planted it. It was over 6ft tall when I planted it and has pushed 1 or maybe 2 flushes since then.

Here it is on August 27th, 2011:

Check the bottom of the pot!
