Ok, more info on the orange flesh guava. The one I have is still a small seedling. It is called Gushiken, USDA cultivar HPSI 26.
Here's a few photos of what the fruit should look like, but not sure if the seedling will have similar fruit.



i had ate something similar to this around two years ago, the fruits were the size of big plums slightly pear shaped. The colour thought, it looks like pink to me too so ....
I have three seedling plants which are big now so hopefully next year i will see some fruit on them.
I also have three seedling plants from a bigger fruited ,pink guava, probably similar to apple guava. Two of them set fruit this year ,but due to the colder temps in the gh they are not sizing at the moment.
I had fruit this year from two catley guavas , both the yellow and the red varieties.
I liked the red strawberry guava the better, had more sweetness, very good flavour with a small amount of seeds per fruit. Fruits were the size of a medium large round plum. Both the peel and the inside just melted into the mouth, the peel had a slight piney flavour which i very much liked.
The yellow one, generally called lemon guava was kinda bland compared to the other.

I have always germinated them in small flower pots with basic plant soil with perlite. Fresh seeds sprout way faster and generally as a group, stored ones sprout very slow and u get ones that sprout 8+ months later, ive had poor germination from stored ones also. I sprout them at room temperature, around 20C.
They are generally very easy to sprout, last winter i sprouted around 100 seeds, most i tinned, the rest ( 60 or so) were stransplanted in small plastic cups and are now in my basement for the winter with the citrus.

Thanks for the replies, i will buy one or two next week, hopefully they get softer and i am able to pick the ripest ones from the pach.
Last year i did not had any succes with the seeds, i even had one that had germinated and had roots, yet still it molded and rotted. I used peat moss and soil also, same story.....

Mameys that are picked under ripe will soften up and can taste good, but they will never ever taste as good as one picked ripe from the tree. To tell if a mamey is ripe you can scratch it like you did. Problem with that is even the store bought mameys, when soft, tend to show an orange color even if they were scratched a week ago and showed a green color. it is not the same as fresh off the tree. Anyway, I have gotten high germination rates on ones from the store, wouldn't hurt to try.

Jaboticaba45 did u plant them whole ,i mean with the shell, or u pry it open and planted only the embrio ?? Thanks!

I recommend a pretty bland soil mix for them like citrus / cactus mix that has lots of sand and stone in it for drainage. They are prone to root rot.
thanks , i will make a fast draining substrate with perlite and sand as u reccomend  and will plant the seeds whole with the shells.

Thats nothing, plants survive with way more severe inguries. Looks healed also.

Just found theese were available and they seem way under ripe now, compared to those past year when they were alot more softer and had the right colour under the peel.
Now i know the scrape method, tested it on some of them and the color underneath is a light greenish/yellow , no salmon colour.
Almost every fruit was rock hard, some of them were getting a bit softer, csraped those a bit and its the same greenish colour.
Last year i bought a rock hard one and it just molded inside instead of ripening. I quess they will not properly ripen ,to be consumable, no ?
My main target of course are the seed ,but do they have a chance on sprouting if they come from an underripe fruit ?

I am just highly let down by this, since i'm a big fan of tropical fruit and will buy everything new, but the stores just sabotage themselves importing such bad guality fruits. People will buy once and never buy again, there will be no demand on those fruit ,thus no availability. Thats a big shame, the prices are also skyhigh for a fruit that deserves to be in the garbage can........

Chris, you can distinguish dead branches from good live branches by looking at the piece you cut. If you look inside the cross section of the cut and you only see dry/brown color it's dead. If you see either white or green color cross section and maybe the cambium layer is not dried out then it is alive. Just cut any small branch that has no leaves and looks bad or dried out starting from the tip of that branch section, then keep cutting that branch back to where is originates from the main trunk or secondary branches that are growing good (leaves, green wood). If you are not sure if its dead or alive then leave the branch alone.

Post a before and after photo of your tree.

Another trick to find dead branches is to scrape some bark with the nail or some other object,  if its green under its alive.

Plantinyum, take a look at the leaves of my vine, I see 3 pairs of glands (6 total) so does it mean my plant is a P. Quad?




I am not sure but judging by the above article, it may be it. I see that your plant has three sets of glants on every leaf, no matter the size. I am saying this since my plant has tre sets only on the biggest leaves, the smaller ones have two sets. I cant see by your photo ,but the glands on yours seem smaller than the  ones on mine, which are pointy.

Your leaves also seem rounder than mine. I did not harvest more leaves to picture since the plant is in a poor condition right now. I have shown a petiole and the glands on it also. The perfect leaf is pretty much how all of them are, as shape goes ... the biggest difference i see between both plant leaves is that mine has this elongation on the tip of the leaf, i'm sure there a botanical name for that...

I always get theese over summer, since i add lots of manure to my plants in the garden. They eat mostly rotting matter but i think they nibble on vegetable roots also. Not sure about tree roots...

So just checked my plant and the petioles mosly have two pairs of two glands every petiole. Some of them have three pairs...
So was reading s3veral studies on the subject, and this one does an comparison of alata, quadrangularis and decaisneana. Decaisneana is said to have 4 glands on the petiole in 90%of the time, compared to quadrangularis which should have 6 glands most of the time.  Alata is out of the guessing game, since its flower is vissibly different, whereas the other two are harder to distinguish apart. This information iis basically the same , compared to the one provided from MisterPlantee.
Also by the pic my flowers look closer to decaisneana, so hopefully ive got my proper id .
Several studies also claimed that decaisneana is commonly sold as quadrangularis, another hint.

Here are a few pics of mine when it bloomed. I had posted pics of the blooms before , but they were with an stranje off colour to them from the pic, so posting those which are closer to the real deal.
I still cant differenciate the flowers of  quadrangularis, decaisneana and others that look close to those two.
However now when i took a look of the flowers of my plant, the look kinda different to those of SC4001992, mine are not so wavy....

I have Hoang's passiflora decaisneana that I grew from cuttings this past winter ago.. It went crazy over the summer, got probably 100+ flowers.. Finally ripened a couple weeks ago.. The flowers look different than yours, maybe yours is a hybrid?












What was the taste of those beauties ?? Was the rind edible ?

Yes, you may be correct about the cold temperature and no pollen. But my purple fruit passion (passiflora edulis) flowers seems to have no problem with lots of pollen and when I hand pollinated them last week the fruits set and it is doing well.
edulis is bullet proof for me . Flowers are awlays full of pollen, sets truit on every hand pollinated flower, some times on ones that i havent pollinated also...
Another problematic passiflora for me is ligularis. The two plants got huge, had tiny flower bud starts all over the place, none of which managed to grow and flower. If those and my quadrangularis do survive the winter i will give them one more summer ,and if there isnt any impovement i will take them out and plant an purple edulis, which has never let me down on fruit production.

Janet, wow your fruits looks big already. I hope I get one flower to set fruit. I just pollinated 2 more today and I saw another 5 that might open by next week. When I looked at my flowers closer it looks like it doesn't have any pollen on the pedals so maybe that's my problem. It may need another year before my flowers have pollen. I just used my purple passion flower pollen since the PD didn't seem to have any in the flowers.
My plant was also very variable in regard  to having pollen on the flowers. Some of them had a good amount, others had none. I think the late flowers barely had any pollen, low temps may be the cause.

Not a pro in this, but could this tree use some rejuvenation trimming to produce new young branches? I also see alot of dead branches( small) in there, its becomed entangled and this is preventing air flow ,thus the chance of desease increases. I am not an expert in citrus ,but that's rather a generall tree care thing.
U can use the trimmed parts to start new plants also!

I read above that people are pruning to make their trees more compact.  That works of course, but it isn't hard to keep trees compact, potted or not.
I learned from someone in North American Fruit Explorers that the apical bud, the bud at the end of a twig, gives off a hormone that reduces bud break below it.  Making a notch just above a lower bud will prevent the hormone from going down to that bud, and it will (usually) turn into a twig, then a branch.  This is done by hobby fruit growers to control their tree growth.  Commercial fruit growers find this method too expensive when growing hundreds or thousands of trees.
I haven't tried this on citrus yet.  But I tried this method on a seedling wisteria and got a branch at EVERY leaf axil.  Ordinarily wisteria don't branch at all until they are bigger.  I had a branch for every leaf since germination until I quit doing the notching.  Then it stopped further branching.
I'm not doing this on my seedlings because seedlings don't bloom until they get a certain height.  That certain height is different for each unique seedling.  I presume each nucellular seedlings of the same variety would bloom at the same height.
Grafted plants and rooted cutting could be notched at any time as they are from mature wood.

woudn't it be easier to just trim the terminal bud?? Do the remaining buds that are just below  the trimmed one take its function and become terminals themselves?

Kaz, in my experience when the vine isnít ready it wonít hold any fruits no matter how well you hand pollinate them. Happened to me the first year. No fruits despite hand pollination. Then second year it worked totally fine
I really hope that this is the case with my plant also, hope it sets something next year and i will try to find a way to make it bloom earlier ,while the warm weather is present.
One thing that i wonder is if the colder temps triggered it to bloom that late??

Yes, I hope I get more than one flower opening at the same time so I will cross pollinate the flowers. I also heard from Hoang that it's to late now for the flowers to set and that they will probably all fall off. Since it is the first time my vines have flowers in 5-6 yrs maybe it will be different and set one fruit.

i dont think that crossing flowers from the same plant will work, its the same genotype.  U need a different plant from the same species, or other passiflora species that are known to succesfully cross pollinate  with quadrangularis and its hybrids .
Yesterday i saw my plant having one flower bud thats growing, funny since its close to the wood stove and got 50% of it severy toasted from the heat. I am not heating right now, just had several test firings, one time i got the fire so strong it just partially damaged some of the plants close to it.

The plant is currently also having new vegetative growth, the lowest temp in gh till now was 3.8 C.

I have a question for both you Plantinyum and Kevin.

Did you ever get a fruit to set on your passion fruit flower?

I have one that I don't know what variety is it. I bought a small plant thinking it was Lilikoi but after I posted my flower photos I was informed that I have a Passiflora Decaisneana.

Here's a photo of my flower on my vine. I also have another 4 flowers that will open in a week (11/27/21). The first flower shown in this photo was hand pollinated but it did not hold, if fell off with no fruit set.




hi, no i did not get any fruit set on mine the past year ,back then it only had like 2-3 flowers.
This year i planted it in my gh in the ground and it exploded with growth trought summer, it started blooming around september just as the temps started to cool down.
It had i would guess around 40 flowers this year ,as one might expect i self pollinated them as best as i could yet it did not set any fruit this year also.
One observation i had was that the first blooms were the biggest and most colourfull ,as the blooming period was rollin  the blooms were getting smaller and paler, like the one in your pic.  Seems the species is a fall bloomer in my region so it does not help itself setting fruit , since it misses the optimal conditions for the purpose.
In one tread people suggested to cross it with caerulea pollen ,i  was going to do that but instead got my caerulea plants severely neglected and did not had a single bloom this year. If u have one flowering now, i suggest u to try to cross them.

Grow this Meyer lemon thatís 5 years old, not more than 3 feet tall, not including container. Very productive. Have pomeloís thatís either 3 or 4 feet tall. I like minni treeís.








Nice plants ! Are your mini trees grafted on flying dragon ? I have one pomello and a kumquat that seem to be very slow growing, staying very compact since they almost do not make any new growth.
I tend to like plants that are vigorous..however i can see the benefit of the smaller size of them, for space reasons.

Ive also bought from the store a papaya tipe with guite small fruit, labeled as solo. I think i did the sirch some time ago and the variety behind the label was further identified by me as solo sunrise.
They are my fave papaya, very sweet, very enjoiable, no musky taste ever, i have been buing from them whenever i see them available.

Can a new shoot be top pinched after it reaches the desired lenght in order for it to send new branching growth from the same shoot the same year ?
I found this method works very well with avocado, which on its own seem to also make spindly growth without much branching.
I also have two lemons which are my most vigorous cutrus by far ,that are making long single point branches . The plants are young still so i do not have size problems with them for now, maybe next year haha...

My experience with polycarbonate panels is that the snow quickly forms a thin layer of melt water where it touches the glazing, and then the whole pile of snow slides right off.  If you can hold the snow in place it will provide additional insulation, but also prevent sunlight in.

Yeah ,i have the same experience with the policarbonate, but i was thinking now that i have the bubble wrap on ,it will keep the snow a bit colder at the bottom and not melt as much.
Anyway ,i need to try this and see how it goes.

I am also thinking of having a removable hail net on top of the gh, with purpose of adding some friction layer for the snow to hold on to. I think if i manage to hold the snow that accumolates during snowing events, this will help me alot to retain heat on a past cyclone days, when we usually have the lowest temps.
Thats another idea of mine i will try when weather is favorable, thought the snow may just melt away since inside i will be having a wood stove burning...

Seems like the additional layers of bubblewrap and nylon do not stop the suns heat, inside it gets as hot as it did without them, and actually seems that it gets hotter now .
We had some quite cold nights theese days, heavy frosts and ice in water puddles etc. In one of those mornings ,before the sun came out i checked the outside termometer which read -2c but i guess we had temps of arround -4c in some of theese nights. Inside the gh the temp at soil level where the termomether is ,hasnt dropped under 4c. This was before i placed the bubblewrap and nylon on the sides of the gh, only the top was made.
Seems like the top gave an additional 3c warming effect, which combined with the polycarbonate and the ready now side sides of the gh will give me arround 7-8C difference compared to outside. I will have a fuller insight on ghe temp fluctuations and differences in a few weeks when i collect more data.
As a side note the layers did reduced the light that is passing trough, like i did not measure the levels with a device or smt ,but its just visible to the naked eye. However i think the light will be enough for the plants, given i will not fertilize and will water sparingly.
I just wanted to attaing some additional warmth with this, so i think it did work.
