Forester I'm not sure that is a Kadsura. I don't have coccinea, but I have a japonica and a couple of heteroclita. Heteroclita is supposed to look very similar to coccinea. They need more shade than I give them, but this heteroclita in a shady spot is starting to do well. I had a couple of flowers on japonica, but no fruit set.

Tropical Fruit Discussion / Re: More cold-tolerant lychee
« on: October 21, 2020, 11:59:40 AM »
It's probably just bullshit. The Chinese have been selecting lychee for a thousand years, and this guy just happened to breed a variety which withstands 15 F and has great fruit with tiny seeds?

The coloring on that blue and black Rollinia/Dugentia at 0:54 is crazy! It looks like some kind of alien egg. What is it?

Maybe Eugenia hiraeifolia? The fruit are very Eugenia-like, especially the four persistent calyxes. Looking at Myrtaceae in Costa Rica on iNaturalist and saw this pretty close match. https://www.inaturalist.org/taxa/978489-Eugenia-hiraeifolia/browse_photos

It surprises me how many people are saying dragonfruit are no good. I had some delicious white-fleshed (red-skinned) DF this year. They get good once they sit on the vine fully red for a few weeks. Don't pick until the connection gets floppy (thanks Spaugh for that tip). Especially good chilled to nearly frozen.

I think there are two species being called Eugenia myrcianthes/Hexachlamys edulis. The sweet one looks very different from the garlic one. The garlic one has multiple trunks, looks like a willow, rough bark. The sweet one is a much prettier, smaller tree, somewhat resembling an annona to me, with smooth trunk. The garlic one has longer leaf petioles, narrower leaves, and less pubescent leaves when the leaves are mature. Garlic fruits are smooth-skinned and lumpy, while sweet ones are round and pubescent.

Some people say the garlic one is Hexachlamys tomentosa/Eugenia anomola, but I'm not sure it really matches the description of those.

That lawn is awfully green. Just been fertilized?

This talks about two types, with the smaller-fruited one being better: https://hort.purdue.edu/newcrop/proceedings1999/v4-348.html

No fruit yet. It was tiny when it came in May. It's not supposed to be a great fruit.

Congrats! it is not easy to grow Guaporetí! morning sun, rain water?
Thanks Marcos! I gave it more sun this year, no shade until 2pm for most of the summer. I felt like too much shade and moisture was contributing to the brown leaf tips. It handled the sun, but when I move it into shade it gets beautiful flushes of new leaves, like it has now. I just use city water, and a little sprinkle of sulfur or manure every once in a while. It's good to hear you're getting set up to get phytosanitary certificates.

Check out other Asimina species. The others are all native to Florida, and are generally smaller than triloba. Lots of potential for dwarfing and other weirdness. https://www.indefenseofplants.com/blog/2018/3/13/the-other-pawpaws

« on: September 21, 2020, 04:13:08 PM »
Which cultivar names are used for two cultivars of different species in the same genus? Usually it's the same cultivar with disagreements on what species it is, e.g. Eugenia calycina 'Nelita' vs Eugenia involucrata 'Nelita', Dream Annona vs Dream Atemoya, Plinia jaboticaba 'Sabara' vs Plinia cauliflora 'Sabara'.

Temperate Fruit Discussion / Re: Pawpaw nutrient deficiency help, please!
« on: September 18, 2020, 05:52:33 PM »
I bet it will go down on its own in time. I'm hardly finding anything about reducing excessive calcium levels, which makes me think calcium probably won't stay high on its own. Maybe adding Epsom salt (MgSO4) would help? Then again doing anything might just make it worse. I saw some stuff about Phosphorous and Sodium removing Calcium, but you could easily do more harm than good. One site said growing leafy root crops with high oxalate levels would help. https://www.researchgate.net/post/How_to_reduce_excessive_calcium_levels_in_soil

"Gypsum is not acid soluble and will not change the soil pH. It helps to shift the Ca and Mg levels in soil and offers a readily available form of sulfate sulfur, a valuable secondary nutrient that benefits the soil and crop. The sulfate in gypsum binds with excess Mg in the soil to form soluble Epsom salt, which moves lower into the soil profile. This Mg is replaced by Ca, improving water holding capacity, root development and soil quality." source: http://www.gypsoil.com/news-and-events/gypsum-and-lime

If the Ca causes the Mg to precipitate as MgSO4, I don't know what adding dissolved MgSO4 would do. Maybe some of the SO4 would combine back with Mg and some with Ca in the soil, but if there's MgSO4 in the soil already that's come out of solution... idk. Maybe "lower in the soil profile" means the MgSO4 is basically out of the picture. People do say MgSO4 makes blossom end rot worse by reducing Ca availability, so maybe that would work.

If you look at the ratios of potassium to magnesium in the soil vs in the leaf, it's 194:393 in the soil vs 0.96:0.11 in the leaf, or about 1 to 2 vs 9 to 1. Sounds to me like there's an issue with magnesium uptake. Since the pH was 6.8, which seems on the high end for pawpaw, I doubt it's too acidic. From the table on this site, 0.11 Mg would be low for basically any crop. It also says if you have over 150 in the soil you don't need to add any for corn, so I doubt your soil is deficient in it. https://extension.umn.edu/micro-and-secondary-macronutrients/magnesium-crop-production

I think the issue is excessive Calcium. "In nutrient solution experiments it has been shown that high availability of the cations Ca, K and Mn can lead to strong decreases in Mg uptake... Slightly increasing the Ca concentration in the nutrient solution then rapidly restores the membrane functionality, so that the uptake of other cations is enhanced and leakage reduced. Further increasing the Ca concentrations in the nutrient solution then turns the positive synergistic effect of the nutrients into an antagonistic cation competition for uptake. This is reflected by a reduction in uptake of Mg (and K) when the Ca concentration in the nutrient solution is further increased"

https://link.springer.com/article/10.1007/s11104-012-1567-y

Edit: I looked and Epsoma Organic Soil Acidifier is only 18% elemental sulfur. 80% is gypsum, which contains calcium.

With the leaves about to go deciduous and drop, seems like discoloration shouldn't be too concerning. That said my guess is magnesium deficiency. "symptoms consist of interveinal chlorosis (leaf veins stay green while the regions between them turn yellow). Older leaves lose their green color except in the veins. "

I have spots like that on my tomatoes from the ash or the smoke. Could be that.

« on: September 14, 2020, 11:58:21 AM »
They can take a while to sprout. Just plant them in soil next time don't put them in wet plastic bags. You may have broken the root when you transplanted it, but it may grow a new root. I planted four this year, three from one tree and one from another. The three from one tree all sprouted maybe a month earlier than the other, but that one is now the biggest. Your one survivor is looking good though, much bigger than mine, planted about the same time.

Red jaboticaba seedling. I'm hoping it doesn't revert to normal. I think it may be Red x White, but if that's true what is Escarlate?

Temperate Fruit Discussion / Re: Caprified Figs
« on: August 25, 2020, 05:26:54 PM »
I got it from Adam at Flying Fox Fruits. I had it labeled as Thai Dwarf mulberry, not sure if the mixup was mine or his, probably mine. It took me probably six months to realize this wasn't a mulberry :D. He sent me some fig cuttings too, but none I had labeled took. I didn't know they should be rooted in bags or water, but somehow this one took in soil in June. It grew extremely vigorously He sent Sbayi, VdB, and Improved Celeste, but he wasn't sure on the IDs. This somewhat resembles Improved Celeste, which is supposed to change a lot with caprification, but Improved Celeste usually has less leaf lobation, and the uncaprified fruits are a bit small to be Improved Celeste. Sbayi looks to have red flesh even without caprification.

I got a few cuttings off figbid, but none of them rooted whether in soil or in bags with moist vermiculite or perlite. Rot set in after a few months. You're probably thinking of figs4fun, an old(?) forum. The wasp is probably Blastophaga psenes, native to the Mediterranean, as is Ficus carica, with which it coevolved. There are some established populations in California. Basically where figs come up as weeds there are wasps. Figs produce one or both crops with or without pollination. Most named varieiteis are common type, which produce both breba and main crops either way.

Temperate Fruit Discussion / Caprified Figs
« on: August 24, 2020, 09:42:10 PM »
I have an unknown fig variety bearing for the first time this year. No breba crop, maybe due to late-season pruning last year. It's been producing a lot of small amber-fleshed figs with a purely sweet flavor. After eating about twenty I bit into one, and found bright red flesh. It tastes like a mix of strawberries and raspberries, with a bit of lemon. I ate a few more amber ones before I found a second red one. I am blown away, the taste is so much better! It's got a lot more jam inside too. Both of the red ones I found were on the same branch, on the south side of the tree. They were also a bit bigger than most of the amber ones, and now I notice some ripening ones that are bigger and more spherical than typical.

Is this caprification, and is this much difference typical? I'm amazed at how much better the red ones are.

Caprified?


Comparison with amber/uncaprified


Guessing these are caprified
