Tropical Fruit Discussion / Pictures of the world's northernmost avocadoes?
« on: August 19, 2023, 02:28:48 AM »
Anyone has pictures of avocado trees that grow way beyond what one is used to seeing?

Were talking Zone 8a or even slightly further?

Tropical Fruit Discussion / Black Sapote - Persimmon Cross, is it possible?
« on: July 01, 2023, 05:07:41 AM »
Can you hybridize them to create a cold tolerant black sapote tasting fruit tree?

Tropical Fruit Discussion / Can loquat be bred for temperate climate like pomegranates?
« on: May 17, 2023, 01:16:25 PM »
Like russians developed many pomegranate varieties that can handle much colder temps than temps they are originally exposed to

Can you do the same thing with loquat?
The only issue that comes into mind is that they start flowering in december so unless it mutates to flower in spring instead its not gonna happen

But it makes you wonder about the possibilities of zone pushing

Tropical Fruit Discussion / Why did kumquats evolved to handle 15F/-9C when its fruits freeze easily?
« on: May 06, 2023, 04:42:53 AM »
To make the tree essentially tolerant to pretty deep freezes, yet its fruits to die at barely around -1C/-2C temps

Is it because normally the fruit matures before winter where the plant is originated from?

Tropical Fruit Discussion / Tropical climate trees are "less efficient" by nature?
« on: May 03, 2023, 01:39:26 PM »
...than temperate climate trees?

Its as if tropical fruit trees are unable to "do the work" of bringing flowers, leaves at lower temps whereas temperate trees (apples, plums, apricot, pears etc.. ) do that with ease..
What is the science behind this?

Interestingly enough it not only affects tropical fruit trees but non-tropicals as well that came from the tropics, subtropics (but somehow evolved to handle colder temps eg: Asimina Triloba). They are really starting to wake up once night time temps go above 10C/50F

Can it be that as science advances we'll be able to manipulate whatever that is causing it to wake up early (and thrive), or push it with selective breeding?

Tropical Fruit Discussion / Planting 1000s of seeds from the cold hardiest avocados (experiment)
« on: April 15, 2023, 02:42:49 AM »
Or 10 thousands of seeds from the hardiest of avocadoes of all times (Joey, Fantastic, Lila etc.. )

Can we go down another half a zone maybe to reach Zone 7b, or a solid Zone 8a plant with natural selection and 7-10 years?
Is anyone doing this already?

Tropical Fruit Discussion / Can I save this avocado graft by approach grafting?
« on: February 12, 2023, 02:20:34 AM »
.. by approach grafting it onto another seedling?







As you can tell the main stem is drying out, Im wondering if humidity would help it to recover or its heading for certain death?
It started a few days ago, now Im thinking approach grafting it would be the only way to save it (newly formed stem)

(BTW the seedling is not moldy it simply looks brown when its young)

Tropical Fruit Discussion / Ordering from frutalestropicales.com to Europe experiences?
« on: January 24, 2023, 01:40:55 PM »
Wanna buy this Gomera4 mango: https://frutalestropicales.com/en/home/96-mango-gomera4.html

But its impossible to reach them via mail or by phone, possible cause of their shitty system. Nevertheless Id still like to give them a chance ordering to middle Europe. They're from Spain I believe

Anyone got any experiences ordering from them? How was it?

The small ones in the picture?

Tropical Fruit Discussion / Cultivating subtropical trees in freezing climate (avocado,citrus)
« on: January 03, 2023, 01:17:37 PM »
Found this article: https://www.lowtechmagazine.com/2020/04/fruit-trenches-cultivating-subtropical-plants-in-freezing-temperatures.html

Here it explains how if you train the tree to have this "creeping shape" rather than a normal tree shape you gain a warmth of 2-3C degrees for the winter and quite a bit of cooling for the summer


This should be enough for Zone 7 (at least in my case we barely have -10C every few years) so if you want lemons or avocadoes(the cold hardy ones) it might just be possible, maybe cover it with hay if you wanna be extra careful

The only issue that could come up is that the fruit will touch the ground, not sure how to overcome that, maybe training the branches to face upwards?

Tropical Fruit Discussion / Using approach grafting to graft more genetically distant trees?
« on: December 15, 2022, 10:54:13 AM »
Ive read that with approach grafting you have less chance for graft incompatibility to occur
Does that only include cheimical incopatibility (virus, fungus attack) or when a more genetically distant scion is used?

To be more concrete...  would it be possible to graft avocado on red bay this way? (Both are in the lauraceae family)

Tropical Fruit Discussion / Are seedlings always more hardy than grafted plants?
« on: October 30, 2022, 05:11:40 PM »
So if you have a tree that tolerates 10f/-12C on paper,

Does it mean if I graft one of its seedling with one branch off the tree together then in 3-4 years they will be just as hardy, tolerant of cold, disease etc.. as its non grafted counterpart?

Or the weak point after the graft remains long after the grafting is done and never actually heals 100% only 99% at best?

Follow up question: If thats the case can air layering be a solution to this since its roots and the stem is identical?

Tropical Fruit Discussion / Does anis like scent in avocado leaves indicate cold hardiness?
« on: October 24, 2022, 03:31:40 PM »
I have a few seedlings from store bought avocadoes and some of them have features like
  • anis smelling leaves
  • and the newly emerging ones are red colored

The weird thnig is that as far as I know there arent many actually Mexican avocadoes in the store yet these definitely inidicate Mexican origins

So how can this be? Is this even a legit claim that red and anis smelling leaves are an indication of cold hardiness/Mexican origin?

Tropical Fruit Discussion / Hardiness of the Puebla Avocado
« on: October 05, 2022, 03:52:19 PM »
How cold hardy is the Puebla Avocado?

All I know is its of mexican origin but no info on how hardy it is actually

Tropical Fruit Discussion / "Breeding" cold hardy avocadoes from supermarket seeds?
« on: September 17, 2022, 10:38:06 AM »
Saw a guy on Youtube talking about how you can plant a bunch of seeds from the supermarket outside in Zone 8-8b, maybe give it protection when it falls below minus 1-2 C. (and you can push it further as it grows )
And if it survives then you've potentially created a cold hardy avocado rootstock (Regardless of the origin of the seed)

Now you have to work with a large number of seeds, maybe only one in every 10 survives

The video: https://www.youtube.com/watch?v=O2gaZ6i4qZQ

Is this legit doable? Im starting this experiment, just wanna get some insight from someone who might have succeeded already

Tropical Fruit Buy, Sell & Trade / Where to buy Hardy Avocado trees in Europe ( Mexicola, Steward etc.. )
« on: May 07, 2022, 02:19:44 AM »
I havent found any sources in Europe, only in America, too bad I cant get them send here because
- it would be against their policies
-Via ebay I could get cuttings but they would most likely die until they get here

How can solve the mystery of getting hardy avocados to my country?

(I wanna have them in an sunken unheated greenhouse)
