Tropical Fruit Discussion / Grafting pond apples
« on: November 27, 2020, 12:29:29 PM »
What annonas will pond apple (as a rootstock) be compatible with to graft?
I am most interested in cherimoyas, atemoyas, and cold hardy Brazil/Argentina rollinias and annonas...

Temperate Fruit Discussion / Stonefruit Canker?
« on: November 13, 2020, 05:53:52 PM »
What disease is this? I believe it might be some kind of bacterial canker but I can’t say for certain? Anyway it’s nasty.. looks like it infected just about every Japanese plum at Lowe’s.. can a plant survive this or will they all succumb? Also the Florida peach varieties seemed unaffected while every Japanese plum has it to some degree.. ?

Tropical Fruit Discussion / Hybridizing Artocarpus
« on: November 01, 2020, 08:38:23 AM »
Lakoocha and perhaps Kwai muk will survive in my climate zone long-term. However jackfruit, champedek, and others along those lines will eventually succumb to frosts. My question is, is it possible to impart fruit quality and size from a jackfruit/champedek into an offspring with the cold hardiness traits of lakoocha/Kwai muk through hybridization?

Also a long shot but what about hybridizing durian with artocarpus?

Tropical Fruit Discussion / Bacon avocado fungus or bacterial blight?
« on: October 22, 2020, 07:56:42 PM »
Is black spotting on green wood like this on a bacon avocado normal?





I think the spotting above is pretty normal?
But then there’s this type of black spotting that looks more like blight or maybe phyto fungus taking a hold? Every branch that developed this ended up dying I believe.. this is on a sapling bacon.. I started rubbing a liquid sulfur product onto the trunk and branches kind of as a last ditch effort.. this thing has been dwindling down for months now and I’ve tried quite a few protocols but idk it’s probably a goner

Tropical Fruit Discussion / More cold-tolerant lychee
« on: October 20, 2020, 03:47:00 PM »
Anybody have any more info on this particular tree, or any idea as to which heritage it originated? Is of particular interest especially here in the upper gulf coast where we get into the winter teens occasionally.

Temperature/Zone
25°: F, between zone 9b and zone 10b. I am currently developing a cold hardy lychee tree. As a young tree (1″ caliper), it has withstood temperatures as low as 150: F, without any damage at all. I hope to have this tree available eventually. I’ll keep you posted. [/quote

Tropical Fruit Discussion / Unlabeled variety of mango from Brazil
« on: September 26, 2020, 08:25:40 AM »
Curious if anybody knows what variety these are? I was thinking Kent, but they don’t have those white polyphenol spots like Kent, and are also a bit too bright red to be Kents.. ? Still too hard to cut into yet..

Tropical Fruit Discussion / Cereus peruvianus
« on: September 24, 2020, 09:49:35 PM »
Just bought one but reading conflicting advice on frost tolerance.. not sure if I want to plant in the ground or not? Some say Peruvian apple cactus is hardly frost tolerant, others say it will take a brief hard freeze once fully established, others say it’ll take down to 15F..?
Also any rainfall/humidity and propagation recommendations?

Tropical Fruit Discussion / Which Phillipine style mangos grow well in Fl?
« on: September 24, 2020, 08:09:27 AM »
Apparently Ataulfo and Mallika will not grow/produce well in Fl? So which Philippine-type mangos will (maybe NDM)?

Temperate Fruit Discussion / Pecan question
« on: September 19, 2020, 08:17:05 AM »
Spent a windy day before the hurricane picking up bags of pecans from under 2 massive pecan trees. Not sure what variety they are, but they are huge and probably 50-100 years old or older. How can I tell if they’re of the ‘paper shell’ varieties?
Naturally I won’t be eating any of these but propagating them all. Must they be stratified before germination?
Thanks

37
Damn Sally squashed two of my Mexican avocados. One is a Joey, the other Fantastic. I might as well use 18+ ft of avocado wood to propagate. However, all I have for rootstocks are seedling hass and I suck at grafting avocados anyway. Do I stand a chance rooting these varieties up from cuttings? I’ve gotten callouses from small branches of a Lula or Lila once in the past.. never could root a hass cutting or even callous one though. And definitely no experience with taking cuttings from pure Mexican lineages...?? Any help greatly appreciated

Tropical Fruit Discussion / Advice for ‘my’ ideal mangos..?
« on: September 18, 2020, 03:09:51 PM »
I’ve only ever tasted Kent, Keitt, Ataulfo, Tommy, Haden, and Asian Green (no idea what actual variety, most were slightly sweet/bland maybe like a Keitt, but I did have one that tasted like sweet lavender and that was good)

Basically from that list I’m pretty satisfied with Kent and Ataulfo (I’d rate 8.5/10 for both). I  H A T E  TOMMY AND HADEN. LET ME BURN A FIELD OF THOSE. Keitt sucks too, Asian greens are slightly better than keitt.

As for other varieties I have in sapling form, but I haven’t yet tasted, are Carrie, Ice Cream and Mallika (I question this’d be like Ataulfo?).. Which all 3 dislike the humidity here, smh 🤦‍♂️

Based on this information can anybody recommend varieties that would taste on par or better than Kent and Ataulfo? I don’t care if they’re old or new varieties. But additional side notes on humidity preferences would also be appreciated! Thanks

Tropical Fruit Discussion / LAKOOCHA!
« on: July 05, 2020, 08:43:15 AM »
After seeing videos of lakoocha going deciduous in the Kashmir region, I have renewed hope about this tree surviving in North Florida!
1. Can lakoocha be hydridized with other artocarpus?

2. Can lakoocha be grafted onto other artocarpus (especially jackfruit)?

3. What are some solid varieties of lakoocha?? Think bigger and better fruit, better cold tolerance?

4. Thanks

Tropical Fruit Discussion / Artocarpus and frost
« on: June 11, 2020, 01:31:49 PM »
Cold hardiest artocarpus-type fruit?
One experienced member told me that durio oxleyanus aka wild durian can survive somewhere in the mid or low 20-degree range of frost events. I’m thinking jackfruit would be somewhere close behind, able to survive probably 25 F..
I had a few understory seeding jackfruits that were unscathed this past winter under live oak cover, and made it through about 10 frosts in the upper 20s just fine. (Meanwhile my soursop suffered heavily). Not sure about a larger tree with more exposure. Seems wind plays a big role in frost damage a lot of the time..
Now I have a couple hundred jackfruit seedlings to play with so I will see where that takes me in the future. Maybe there will be some variation in hardiness.
Also VERY interested in dwarf (Thai?) jackfruit. They seem a hell of a lot more promising to protect and fruit in a northern Fl climate than full size varieties. Must they be grafted or can one root jackfruit cuttings or air layers?
Also how would a dwarf jackfruit scion do on a regular-size jackfruit seedling rootstock?
Thanks

Citrus General Discussion / Citrus HLB Theories
« on: April 29, 2020, 12:07:20 AM »
What all do we know about HLB? Maybe post some speculations as to potential 'cures' and/or better tree maintenance protocols?
I am aware that foliar feeding and mulching heavily helps the plant resist HLB to some degree.
I have also heard reports of that growing citrus under oak canopies has some effect. Why is that? I speculate it could have something to do with the tannins and/or humic acids etc released by the decomposing leaves that in some way is affecting the citrus positively (perhaps enhanced nutrient uptake, ie inducing better xylem/phloem cell transportation), or perhaps just affecting the virus negatively (in our favor)?
Perhaps the oak leaves release a good bit of Nitrogen into the surrounding air that the citrus can uptake through its leaves more readily?
I have also been thinking about experimenting with salicylic acid or aspirin. Those compounds (originally derived from willow extract) enhance circulation and the flow of cells. Not sure if a protocol using this would be effective with citrus. I speculate a solution of it may have to be pH balanced.

Tropical Fruit Discussion / Need to ID this atemoya
« on: April 25, 2020, 05:18:01 PM »
Not sure what type of atemoya this is.. it was labeled as a cherimoya but I don’t reckon it is? The vendor said it was grown in California, but he says it’s a ‘Mexican type’..? It’s rather large (I have large hands) and I spent a buck on it!
Almost 2lb..





Thanks

Tropical Fruit Discussion / Viability of duguetia and annona seeds
« on: April 20, 2020, 10:33:47 AM »
Hello, I paid a premium price from trade winds seeds  for a single ‘anona duckei’ seed and a single ‘duguetia peruviana’ seed in hopes that paying such a high price would guarantee that they were viable. Got them delivered last night and was pretty disappointed. The duckei seed looked light brown, old, lightweight, and riveted like a peach pit. Not sure if they’re supposed to look like that?as far as I’m aware most annona seeds are dark brown and flat?
The duguetia seed looked alright but was also a bit light in weight. I threw em in a glass of water to do the floating test. They both floated. However, I kept them in the water overnight and now the annona duckei seed has sunk to the bottom but the duguetia seed is still floating. Is this an accurate way to test viability on these species? Was I scammed (and should try and get my money back?!) or should I go ahead and stick em in some soil? Please help!

Tropical Fruit Discussion / COLD HARDY LYCHEES & LONGANS
« on: April 16, 2020, 02:26:51 PM »
Looking for a seedling or commercial variety of lychee and/or longan that can withstand brief drops into the mid to upper teens F. Actually Randy from ‘Randy’s tropical fruits’ has already developed a cold hardy lychee. I believe from the ‘Hap Ik’ or sweetheart heritage, which can withstand at least 15 degrees F.  However it’s up in the air if he’ll ever sell propagations from it for whatever reason.
I believe another potentially cold hardy heritage of lychee could originate from the mountainous ‘Emperor’ heritage.
As for longans, from personal experience they are at least more frost tolerant as a species as a whole than lychees.. not sure about actual ‘cold’ tolerance though.. probably similar. Might even be an easier shot to find a cold hardy longan than a cold hardy lychee.
Any info greatly appreciated.

Tropical Fruit Discussion / COMMERCIAL COLD HARDY AVOCADO BREEDING
« on: April 16, 2020, 02:18:14 PM »
How difficult would one suppose it’d be to cross a pure cold hardy Mexican avocado (Lila, Joey, Brazos Belle, Fantastic, Pancho, Mexicola) with a more commercially acceptable variety like Hass (because it’s decent quality and ships well... although many say the cold hardy varieties taste even better anyway!) ??
Like the product of hybridization being a cold hardy hass that can get down into the teens.. or a Fantastic avocado with tough outer skin that ships well.. I believe this would extend the growing range in the US greatly.. and perhaps into areas where those damn boring beetles won’t destroy the plants!?

Tropical Fruit Discussion / COLD HARDY ANNONAS
« on: April 16, 2020, 02:05:54 PM »
Need expert annona advice!
There is very little information available in the US on this subject specifically.. some obscure and anecdotal evidence..
Basically I am looking for annonas that will survive comfortably in a lower 8b/northern 9a climate zone. Where minimum temps usually only dip into the upper or mid-20s, BUT every few years we will see rare, brief,  mid-to-upper teens temps (which pretty much constitutes as a ‘moderately severe’ or ‘hard’ freeze). So once every 3-4 winters it might drop down to 17-20 degrees F.
So, from the information I have gathered so far, I believe these species are hardy for my climate zone:
Annona rugulosa
Annona/rollinia sylvatica
Annona/rollinia emarginata
Annona ubatubensis
“Dream” annona
Annona parviflora
And PERHAPS select individuals from these species:
Annona montana
Annona hayesii
Annona hypoglauca
Annona crassiflora
Perhaps some other types of Cherimoyas and Atemoyas.
And perhaps some types of Duguetias.

I have found that most of these hardier annonas originate from Southern Brazil, Uruguay, Argentina, and highland/ mountainous tropical/subtropical forests such as in Peru.

Any additional information would be GREAT! Thank you!
Also seed sources would be AWESOME!
