Title: Interesting Story about these two cold hardy avocados.
Post by: JoeReal on May 10, 2019, 02:23:02 PM
Story about the **Aravaipa**:
Here's what I found out about the Aravaipa Avocado.

There's a special story about it in the Fruit Gardener which I recommend you'd subscribe if you're into fruit growing. It isn't publicly available as it is copyrighted but accessible via paid subscription.

There were many avocado trees planted in Arizona and elsewhere near the Mexico Border when parts of the US were still under Mexico, sometime in the 1700's and earlier. So it must be a long time of selection pressure for the various trial avocado plantings, by people freely coming in and out of Mexico and from Central and South America long before the US was formed.

In 1906, a rancher's family purchased the deed to his land in 1906 in the Aravaipa Canyon, now a Conservation Preserve in Arizona, and there was already a good size avocado tree growing in it. The avocado tree must have first sprouted or planted in the mid to late 1800's. The ranch is located at the bottom of a Valley, on a small mesa, just about 10 to 15 feet above the stream bed, and about 180 feet from the Aravaipa River. This means that during winter, very cold air from the mountains, being denser, would drain into this valley creating very cold freezing conditions, but the cold air would continue to drain down further into the river, away from the avocado tree, away from the ranch. According to the rancher, there are a couple of times or more that the entire mesa was flooded with 6-8 ft of water up to the trunk of the tree. Over the more than 100 years since their family acquired the land, the ranch had experienced many wintry snow storms, with regular winters of mid-20's and plummeting as low as 10 deg F. During the summer, the temperature regularly get several days of 120 deg F and sometimes weeks of temperatures above the century mark.

The tree must be at least 125 years old and survived it all to be the great and unique specimen that it is to this very day. What sets apart this tree from other cold hardy specimen is that it is both very cold hardy and heat tolerant. The tree is also salt tolerant, able to thrive in saline sodic soils of Arizona, and tolerant of root rot from the flooding and prolonged wet soils during winter. The tree just laughs off freezing events and continues to be very productive.

The tree is now regarded by Arizona residents as a Native Arizona avocado, and is related to Hass, a Guatemalan race, and avocado aficionados know very well that Guatamelan varieties typically have rough tough skins and are the most cold sensitive. So indeed this variety is truly unique in that it is very cold hardy and heat tolerant at the same time. Hass will simply burn in very hot summer temperatures or die out or severely damaged after a few frosty nights during winter.

The cultivar is just starting to become popular. In my quest for having a fruit bearing avocado tree in North California, I seek out and added this to my collection. Thanks to my friend Harvey Correia who first told me about the story of the Aravaipa and let me take a cutting of it from his tree.

One of the drawbacks to its adoption is that some say it only tasted mediocre. Most people don't want anything that isn't at least as good tasting as Hass. Julie Frink, a revered avocado guru, wasn't impressed with its flavor and at best considered it mediocre. But for our area, being mediocre is preferable to having no avocados at all. The current ranch owners of the original Aravaipa tree told that the taste is really delectable when harvested and properly ripened, and they had more sampling of the fruits than anyone else. As for me, one sample isn't enough especially if you're tasting many other avocados. A sampling through time of various harvest dates and ripening period is the best gauge for evaluating the quality of the fruits. Also the age of the tree has tremendous effect on the fruit quality, just like old vines making better wines than newer vines. I learned that as a winemaker long time ago, that you'll have to bring wine across its journey through time, and one bottle isn't enough. Flavor quality changes through time. Sometimes a slight modification in the "curing" or storage of avocados can dramatically change their flavor profile, and we don't have a clue on how to handle Aravaipa Avocado, such as optimum harvest and storage time.

I hope to get a lot of fruits this year. So I hope to evaluate it properly for my personal recommendations. Regardless of taste, it is a must have variety, at least for me as I believe that it would surely be a good source of excellent rootstock just like the Duke, that are able to tolerate salt, heat, root rot, and very cold hardy.

Unlike the Duke avocado, the Aravaipa can be be ordered online and is often available. It costs more than the typical avocado tree from big box stores as the propagators don't have the economies of scale. But also be aware that there are two types of Aravaipa being sold, one is also sold as Arizona Avocado, and is the original Aravaipa, and the other one is sold as Don Juan which many said is not the original Aravaipa, but dual labeled as such. The Don Juan is said to produce better tasting fruits than Arizona, and so must be another cultivar and I have no idea about its cold, salt, heat and rot tolerance.

Here's a video link showing that the legendary tree exists. The family who owns the ranch and the original tree has invited one of the promoters, propagators and sellers of the Aravaipa avocado. The exact location of the ranch and the tree can't be disclosed to respect the owner's privacy.

Here's the story about the **Duke Avocado**
Part 1:

As I have already mentioned, the best rootstock for our area is from the Duke Avocado Tree. The seedlings can tolerate well water high in boron and salts.  I am suspecting the same for the Aravaipa so am excited to test them.


**Fantastic/Pryor Avocado** is green, paper thin skin, most cold hardy of all the Mexican avocados. The fruit
has a creamy texture with fantastic flavors. Eat skin and all. It is a vigorous growing beautiful tree. I am suspecting that the Fantastic avocado has similar genetics to Duke.

**Brazos Belle or WIlma**  is also a cold hardy Mexican avocado. The fruit is large and has a very good flavor. The skin is black in color.

This winter, I have 100% germination rate of Aravaipa seeds and Duke seeds outside the house, in the yard, exposed to the elements, they're in plastic cups. Only the Aravaipa germinated during the winter while Duke germinated during early spring.

I'll begin to experiment on them as rootstocks!
Title: Re: Interesting Story about these two cold hardy avocados.

A couple of years ago, I grafted all the cold hardiest avocados that I can find and so it has 7 cultivars with 5 type B and 2 type A flowers. Earlier this season, they bloomed almost together and there were plenty of bees and syrphid flies visiting the tree.

So now it has heavy fruit sets that I am tempted to thin out the fruits of our avocado tree! From the floor of the deck to the top of canopy, avocados of different sizes and shapes from 7 different cold hardy cultivars on one tree are becoming heavier and heavier, made the tree droop and spread. I worry that some limbs might break.

This is a young tree about 3-4 years old and this is what happens when you have both type A & B flowers bloom at the same time. The heatwaves are just starting so am hesitant to thin it out as many of them would fall off. Will try to brace the tree after another heat wave.

It was hard for me to get avocados going in my yard. We have freezes every year. Many avocado trees have died before I achieved this. Two major things why they died:

Rootstocks: all the rootstocks available from nurseries and big box stores don’t like our water. Too much boron, too much salt, high pH. We also have alkaline soil, so they all die within a couple of years if they survived the cold.
Cold Hardiness: only a couple cultivars available from the same commercial stores are cold hardy but they’ll die if we got freezes colder than normal during the winter, such as wayward Arctic blasts.
So I researched and experimented with my own rootstocks, growing them from seeds of established trees of Northern California and then collected all the known cold hardiest Avocados of North America. And the result is this tree.

Nice to see some success in my area. I'm actually pretty close to some GIANT duke's in oroville.
Did you plant in a mound or directly at ground level? I know standing water is a huge issue out here.

Do I understand correctly that you're using your own selected rootstock? How many seedlings did you plant to arrive at one that "works"? Did you select with all of them in-ground?

Always plant elevated from the ground in most areas of California. I recommend at least 3' x 3' x 1' high planter box (made of retaining wall bricks preferably).

All of my avocados are now on Duke Seedling rootstocks. All the ones that I got from the stores, and other seedlings that I have started resulted in dead avocado trees! 

The Aravaipa seedlings seemed to even be more promising and am trying it this year too!

Very nice work indeed! I'm trying to do the same thing inside a greenhouse in Europe. They are hard to come by, but the Mexican cold hardy varieties are so much more tolerant of our cold and wet winters here, that anyhting else dies, while the Mexicola seeds don't even have one single leaf that burns in some years. I know anyone can think of such a thing, but in practice it takes a lot of planning and searching for specific seeds and cultivars to get a tree going like yours. That is pretty amazing. The seeds of your avocadoes will probably give some interesting new trees as well. Good luck!

I have found out that the first seeds of the Aravaipa avocado germinated during the winter here in our area, I planted them in small cups, outside, fully exposed to the elements. The Duke seeds sprouted much later, only after it consistently got above 40F. 

It seems that the Aravaipa seedlings are able to take our boron toxic and saline alkaline city water very well, showed no signs of salt damage at all. Duke seedlings also, but then the Aravaipa grows more vigorously.  I'll experiment on them as avocado rootstocks.

All the avocados that I got from the big box stores has already died and I am suspecting that the rootstocks used aren't really suited to our area. The trees that are sold don't have the name of the rootstock used.

If the grower was La Verne Nursery, I think he told us on the last CRFG LA Chapter nursery tour they use Fuerte seedlings.

I inquired about ordering some Avos at LaVerne and got the following reply: "The avocado rootstock is Zutano and the height we ship at is about 42” from the ground; we use a 42” stake and it will be at top of stake, the 5 gal container is 12” in height." from Richard Wilson - CEO, on April 24th.

Truly amazing and well planned Joe.  I've heard nothing but good things about the Mexicola.  No, it's not in the same class as many of SoCal avocado hybrids but it's a helluva better than the "Tex-Mex" avocados they push here in Texas: Fantastic/Pryor Avocado, Brazos Belle or Wilma. Joey is another one that's crap. 

Might try Reed.  You may have seen where mine took 18F for a short time and came back from stubs last year.  It's now 13' and flowering.

What nails our tropical fruit trees in Texas is the wild temp swings - 80F high one day, Arctic cold front moves in at night with a low of 26F the next morn.  Trees that have some age, are lignified (woody) and have been acclimated to cold can laugh at the cold hardiness ratings on the label or published in guidelines. 

Having said that, check out my little friend. Smallest praying mantis I've ever seen.  It's sitting on a new Kahalu'u graft.

So true about the wild swings.  There's one thing that I like about Fantastic/Pryor Avocado, Brazos Belle or Wilma and Joey: they make very good rootstocks here! They're better as a rootstocks than the ones that came from the stores. Wilma for example produce a ton of avocados, with mostly seeds instead of pulp (big seed to flesh ratio), but their seeds can still sprout in late winter when planted outside and is able to tolerate our toxic city water.

One of these days, I might be able to plant more exotic avocados like your Kahalu'u when I find space for a greenhouse!

I love the flavor of Mexicola and found them to be much better, smooth and more refined than Hass. A lot of factors can influence the flavor though. Where grown, type of soil, water, fertilizer, weather pattern, age of the tree... it is like wine. Taste of the fruit can vary from place to place and how it as cared for. If you don't like the fruit, graft over it with something you may like.

Joe, they (mexicola) seem to be all seed and no flesh for me.  And they hang on the tree about a week at the most before falling off and becoming bird and mouse food.  And its hardly flowering here while every other tree is overloaded with flowers. 

I've never heard anyone say they would take mexicola over hass.  Makes me wonder if you are only comparing to store bought hass.  Im pretty sure a proper hass will mop the floor with most avocados. 

Speaking of hass, whats the deal with growing them in your area joe?  Can it be done?  Or if not what is the problem?  The heat, the cold, both?  I read the central valley farmers really want to grow avocados but hass wont grow there.  I grew up in Stockton/san joaquin county by the way and never grew avocados until moving to san diego county.

It's funny that my Mexicola here has way more flesh than seeds. Maybe you got the wrong type of Mexicola, or maybe my Mexicola was mislabeled. But whatever, the one I have has smooth skin, you can eat the dark skin, and it is cold hardy, and the leaves has the distinctive Anise aroma. I grafted mine, by taking it from a very mature Mexicola tree of our friend nearby city.

Funny that you asked about the Hass. Just one arctic blast in our area, it could kill the Hass back to the ground.

And in one of those Arctic Blasts, about a decade ago, a friend of ours have the Hass avocado died back to the ground, so they cut it, but not below the graft line. Then it resprouted, above the graft line that year, and grew without any winter damages thereafter. For the past 4-5 years, it has been producing more and more fruits each year. I called it Lynn's Cold Hardy Hass and has grafted it to my collection of Cold Hardy Avocados. So far the grafts took and it showed the characteristically very large Hass leaves similar to during it's juvenile stage as I took the wood from a juvenile branch so I can have more vigorous growth during the first year to catch up with the rest of the cultivars grafted together.

Anyway, I have the pictures of the fruits from my friend's tree and have been giving away scionwood to fellow CRFG members that are interested in order to validate it's cold hardiness.  The taste of the fruit is similar to Hass, it has rough skin like the Hass, only that the skin doesn't develop a really dark skin color like the Hass when ripe. It's dark green with hue of purple, but more towards the green color. The flavor is similar to Hass. Holler if you want to try it there too. I am spreading it around for evaluation.

Here's what I posted in Facebook:
"Lynn Sharman’s cold hardy avocado in West Sacramento. It’s originally a Hass avocado that died down one cold winter, and was cut to a stump above its graft line and resprouted back from the stump cold hardy. It grew and bore fruits for the last 5 years and never bothered again by frosts or freezes thereafter. The tree seems to be self-fertile (has type A & B flowers on different parts of the tree) as it bore a lot of fruits even though there are no other avocados nearby. It’s fruits are delicious with smooth buttery texture similar to Hass and no fibers. Unlike Hass, it’s tough thick skin don’t turn dark when ripe. It has good shelf life and doesn’t bruise easily even when dropped. Thanks to Lynn for the fruits as I will try their seeds as rootstocks. I took as much scionwood for grafting as her house would be up for sale, along with the avocado "

It sounds very possible that neither of the above are true Mexicola or Hass varieties.

You can call it anything you want, you can spend a fortune for DNA or genetic testing, I won't care much.

As for me, it really doesn't matter. If it tastes good, it is able to endure our cold winters and producing fruits every year, then it's a winner. And that's the bottom line.

I agree with the bottom line part Joe.  Thats what counts.  The hass looks like hass.  They look very green still.  I suspect it will get very black of left on the tree longer.

If left longer, the flavor will also improve further compared to store bought Hass. Anyway, that is one cold hardy tree because the leaves don't even get frost bite. The house that has the tree is being sold, so I am getting as much scionwood as I can and give them away to people willing to try. I haven't encountered a Hass Type that is as cold hardy as this one.

Thanks,

First I did research on where the cold hardiest oldest trees are found and when they bear fruits. So during the fruiting season, I looked at the forecast if it is windy. If that afternoon to evening is windy, I schedule a very early morning trip to those trees and then pick up their fruits from the ground. Most of these trees are in public parks and if on private properties, some of their branches extends to the roads and so I pick up the fruits, and I ripen them, got to taste them too, and then use their seeds as rootstocks.

Now I have many cold hardy avocados grafted on to those seedling rootstocks and as they bear fruits, I use the seeds to experiment if they make excellent rootstocks. I usually started them by germinating them during the winter on potting media, and left outside. I have produced many cold hardy seedlings this way. I will have plenty to experiment from my first generation fruits.

You're spoiled and with what perfect conditions you have I don't blame you a bit for being damn choosy.  It's been reported that an old Mexicola in one of the southern states took 5F and survived.

I guess everyone has their preferences for rootstocks.  I found the typical Florida Slimcados, the W. Indies X Guatemalan hybrids like Monroe, to be extremely vigorous and accepting of scions.  My original trees done back in 2012 are on those stocks.

Now I have many cold hardy avocados grafted on to those seedling rootstocks and as they bear fruits, I use the seeds to experiment if they make excellent rootstocks. I usually started them by germinating them during the winter on potting media, and left outside. I have produced many cold hardy seedlings this way. I will have plenty to experiment from my first generation fruits.

Damn, that's what I call passion.  Good on ya!   If I wasn't getting too old for this chit I'd reinvent the wheel with Nuevo Leon and Oxaca Mexican Criolo avocados, growing and selections. I have a connection thru a friend who knows a Mexican avocado grower who grows and sells varieties of the old landrace Mexican cold hardy Criolo avocado trees.  He's offered my friend scions.  i backed out of her request to graft different named varieties due to the risk of customs and other issues such as disease/insect contamination, which I guess you could get around with a quarantine drill.  She would basically have to smuggle them across is what she's telling me.  Here's one such avocado hanging from one of his trees.  These Mexican and Guatemalan avocados come in all shapes in sizes from ping pong ball size to 2 pounders.

First I did research on where the cold hardiest oldest trees are found and when they bear fruits. So during the fruiting season, I looked at the forecast if it is windy. If that afternoon to evening is windy, I schedule a very early morning trip to those trees and then pick up their fruits from the ground. Most of these trees are in public parks and if on private properties, some of their branches extends to the roads and so I pick up the fruits, and I ripen them, got to taste them too, and then use their seeds as rootstocks.

The egg of the bull might just be the shape and size. After all, the original word for avocado is 'testicle'.  Nahuatl name for the indigenous avocado fruit is āhuacatl, that also means “testicle.”

That would be interesting... All those cultivars.  All of the avocados that the US have were originally smuggled in from other countries, mostly from South America and Mexico. The endemic ones were from seedlings of the smuggled ones of ancient days. When US was not yet formed, people from Americas moved about and brought with them plants and animals. Of course those that have established avocado orchards wanted protection.

I don't know of any existing quarantines on avocados, since they're not a major agricultural crop of the US.

You know your testicles well. ;)  Mexico is a bit weird regarding bringing avocados back across the border.  You can do it but for some strange reason the vendor must remove the seed upon the sale.

Here's one Mexican avocado grower in case you do Facebook. https://www.facebook.com/jaime.gonzalez.900388?__tn__=%2CdlC-R-R&eid=ARBq9MEg4CRtHJaQJV-ERVkTV_slqF8oh7bRQ2MRH5L4FJoDe_suzTDFllJ2JlJpx6r-kqTnTWzh7Opg&hc_ref=ARSm137MJLu4gTrAkjARILAiA71ufnyzZqxSxexNBpL13CJTcMxN28eFYVBo1NWflZw (https://www.facebook.com/jaime.gonzalez.900388?__tn__=%2CdlC-R-R&eid=ARBq9MEg4CRtHJaQJV-ERVkTV_slqF8oh7bRQ2MRH5L4FJoDe_suzTDFllJ2JlJpx6r-kqTnTWzh7Opg&hc_ref=ARSm137MJLu4gTrAkjARILAiA71ufnyzZqxSxexNBpL13CJTcMxN28eFYVBo1NWflZw)

I learned something new: 
"Persea americana var. drymifolia trees are characterized by their resistance to cold and
high oil content, a very distinctive characteristic is its strongly aromatic leaves (anise scented)
in almost all individuals; usually, they grow at altitudes greater than 2,000 m. The leaves are
dark green with light green or reddish young shoots; the fruit has a thin, smooth and soft skin,
the seed can be adhered or loose, the cotyledons are smooth or slightly rough, and it is common
to find fibre in the flesh, although this is not found in most cultivated species.
Given that the avocado is an open-pollinated species, it contains great genetic variability with
almost unlimited possibilities for utilization; a wide diversity of germplasm allows the
advancement of botanical and agronomic knowledge and the development of new cultivars."

That's where my friend's friend lives - state of Nuevo Leon.  I noticed some of the improved creoles is what he's growing. 

I would think that if they grew, shipped, and warehoused well, had a good meat to seed ratio, they would be grown in place of Hass.

Thin skin and different appearance... probably not going to replace Hass.

Did you plant in a mound or directly at ground level? I know standing water is a huge issue out here.
Joe, excellent and extremely interesting (and to me) important work that you've presented.  I've been on a similar, if less sophisticated and successful, quest to successfully grow avocados here in Sacramento (Roseville suburb), where we often see the wild temp drops, particularly with these artic inversions we've been getting of late.  I came upon the Duke story (and even held dialogue with it its progenitor and others related to it).  I've made several trips to Oroville to take cuttings and search for seeds.  I've only found one half-eaten avocado from in my visits.  The 2nd set of cuttings I took were grafted onto 2 or 3 box store 5G trees I purchased.  The trees were not healthy due to the winter they withstood, and wild several of the grafts took, the trees ultimately died.  I'm now banking on my Fuerte, Mexicola, and Bacon to survive the transplant I just subjected them to in my front yard.  These trees just produced their first fruit (the Mexicola was excellent) last year.  I had them in large ~50-gal containers for 5+ years.

At any rate, I'll be following your work very closely.

Thanks for sharing.

Ettinger, a B type, is supposed to be pretty good. Big seed, creamy flesh.  It's one of many that was trialed in S. Texas by TX A&M before an arctic front nailed the orchard.

Well we are not Texas...  ;D
At least in my location is very rare to have temp below -3C. 3 years ago we got the lowest ever temp of -6,5C and my bacon avocado survived. Both reed and hass died. So i think ettinger will do well. I Have seeds of stewart and sir prize growing and will have more cold hardy varieties soon, so i'm optimistic...  ;)

I remember Julie Frink being unimpressed by Ettinger.  It is a Fuerte seedling, but apparently isn't as good tasting as Fuerte.  (I planted one for a friend years ago because he wanted one, but I think his climate was too foggy for it to ever produce.)

Always plant elevated from the ground in most areas of California. I recommend at least 3' x 3' x 1' high planter box (made of retaining wall bricks preferably).

Hey Joe,

    So what are you filling the planter box with?  What amendments are you using?
Reason I ask is that I just finished building a planter box for my slope.  I built a 4x4x36”.
My soil here is very rocky.  The top 1’ 6” is sandy loam but after that it’s  hard compacted clay.
Water does not drain well.
I already dug down the 3’ for the planter box and I also dug a hole in the middle of the box another 2’ plus.
I plan on adding some rock to allow water to drain down.  Then I dug a hole from the side of the slope into the bottom of the hole in the center of the planter.  I plan on inserting a piece of 3”  pvc pipe for drainage.
I will be planting 2 avocado trees in this planter.  An A type and B type.
I have a Gem and plan to add a Sharwil.  If I can’t find the Sharwil, might go with Sir Prize.

There's a local landscape supplier that I purchase garden soil. Their garden soil retains soil moisture but it has very good drainage. They aren't giving me their recipe but inspecting it, it has compost, coconut coir dust and sand. I use them as all purpose potting soil and are also excellent for citruses.

Hi Brad, it's the same plants you see in the two images above in the blue bags. I was just trying to increase humidity.  I've never managed to get an avocado cutting to root with this method.  Works great for Fig, stone fruits, olives, and sometimes blueberries though.  I'm sure someone has a more sophisticated method for rooting avocado cuttings that works with a greater than 0% success rate.

I think you need to grow seeds and graft them.  Otherwise all the nurseries would be rooting cuttings.

Yeah, I had extra cutting and thought I'd try.  I've heard with air-layering that it's possible, but grafting is the only "sure way" to propagate avocado.
Title: Re: Interesting Story about these two cold hardy avocados.
Post by: spaugh on May 28, 2019, 12:23:00 PM
Even if you managed to air layer an avocado branch, the root system of a seedling is probably much better.  Im having good success here planting seeds in pots, growing for 6 months or so until they are a foot tall, then planting in ground.  Then let those grow a couple more months and gain some vigor then graft them on in ground stock.  The grafts take really easy on trees already semi established in ground vs in pots. 
Title: Re: Interesting Story about these two cold hardy avocados.
Post by: spaugh on May 28, 2019, 12:30:02 PM
If you are going to do them in pots, it seems to work best if you let the rootstock get a couple feet tall and when you graft it, only remove the top few sets of leaves.  The more leaves left on the rootstock the better it works.  At least for me.  I see the pros completely hack off really small seedlings and graft them.  They have a perfect greenhouse and method though.  For us home growers, its a bit harder to get dialed in.

Post by: z_willus_d on May 28, 2019, 01:33:10 PM
Yes.  I need to find a good source for seeds.  The random seeds from store bought avocados I've attempted to sprout have been hit and miss.  I'd like to get healthy, grafted (to ideal seed/rootstock) Duke, Aravaipa, and maybe one of Joe's "Lynn's Cold Hardy Hass" specials.  I have a couple spots reserved in a raised bed for these candidates.  It would be great to not have to fret so much each winter with the C9 lights and thermal mass heat dispersion assists.

You don't need a greenhouse to micrograft avocado seedlings. Ziploc bags will do. I can graft smaller than these and use tomato grafting clips instead of parafilm. I cover the pot with plastic food bag held by bamboo bbq sticks, secured around the mouth of the pot using rubber band.

August huh? I'll have to make a trip up there. It's too close not too.... :)

Leave some for me? Please....

Joe, excellent and extremely interesting (and to me) important work that you've presented.  I've been on a similar, if less sophisticated and successful, quest to successfully grow avocados here in Sacramento (Roseville suburb), where we often see the wild temp drops, particularly with these artic inversions we've been getting of late.  I came upon the Duke story (and even held dialogue with it its progenitor and others related to it).  I've made several trips to Oroville to take cuttings and search for seeds.  I've only found one half-eaten avocado from in my visits.  The 2nd set of cuttings I took were grafted onto 2 or 3 box store 5G trees I purchased.  The trees were not healthy due to the winter they withstood, and wild several of the grafts took, the trees ultimately died.  I'm now banking on my Fuerte, Mexicola, and Bacon to survive the transplant I just subjected them to in my front yard.  These trees just produced their first fruit (the Mexicola was excellent) last year.  I had them in large ~50-gal containers for 5+ years.

At any rate, I'll be following your work very closely.

Thanks for sharing.

You're welcome! You've been to the very tree that I took most of my seedlings from!

Your secret to success is out, I want in!
I've seen pictures of the tree though and I don't see how I could strip it clean :P I just want a few seeds to experiment myself. I've tried grafting for the first time this year and am amazed at how simple it really is. Would be cool to keep this trees lineage alive.

Very cool.  I judged a persimmon dry white that was excellent at our San Antonio Wine Guild Comp.

Folks don't know it but my area has gone big time with the vineyard ops and wineries, it's the Napa of the southwest.  Must be a new vineyard and winery going in every month and a wine bistro or tasting room on every corner of town.   You may have heard of Jack Keller who has a website and is in our guild.  Jack has probably made wine out of everything.  Rumor has it he even tried St. Augustine grass.  Didn't like the vegetative taste.  ;D  Here's some of his recipes.  https://winemaking.jackkeller.net/recipes.asp

I have made more wines than Jack Keller and won more awards than Jack Keller. To date, I made more than 700 different kinds of wines. I started making wine when I was a kid in the tropics, and have access to much more diverse kinds of fruits that Jack Keller don't have access to.  For example I made wines from Durian, Lipote, Baligang, Aratiles, Sineguelas, Karamay, Kamias, coffee fruits (the pulp, not the beans), cacao fruits (pulp, not the beans) ....

But when someone asks me about how to make wine, I always refer them to Jack Keller's website as a good starting point.  Once they master that part of making wine and if they're still interested, I put them to the next level of winemaking.

Jack Keller's general winemaking can be summarized as a cane sugar wine flavored with hints of fruits. Most recipes use little amounts of fruits and almost all the alcohol are from cane sugar and diluted with lots of water.  My purpose of making wine is to cram as much fruits into a bottle of wine. So I use between 3-6 lbs of fruits to a bottle of wine, while Jack's recipes uses the same amount of fruits to a gallon with added water and lots of cane sugar, and wine acids for balance. Jack Keller's recipes make delicious wines though, but it could be better more flavorful and aromatic if you had just used almost pure fruits with no added water especially if you're producing the fruits.

Sounds wonderful.

My days of making fruit wines are over and that was back in the 60's with such stuff as using tangerines, gardenia flowers, wild Mustang grapes and stuff.  I prefer vinifera grapes and sell to amateur winemakers, about 9 varietals.  Have the best Merlot clone sourced from Beaucastel, etc.   My new semi-dry (back sweetened) rose' made out of Mouvedre and Grenache just won a medal at the T.V. Munson comp.  Tastes just like strawberries.   Here's some 2 pounders from last year.

Getting a bit off topic here.  Be cool to discuss this on another forum.

Enjoyed reading your posts. It would definitely be a blessing to those of us in the colder climate zones, if you can come up with a good tasting cold hardy avocado.
P.S. I sent you a P.M.
Thanks
