Tropical Fruit Discussion / First cherimoya flowers, what to do..
« on: May 23, 2022, 01:28:44 PM »
Hi , the first of 3 flowers opened today as a female, the two other ones i think have a few days to go before they bloom, so i dont really think its worth it to collect the pollen from this one. I shut it tight with a rubber band, to keep it humid and prolly a better chance this way to self pollinate , i think ive red somewhere that keeping the flower shut helps with self pollination, dunno.. 


I just saw my other cherimoya plant ,which has some branching on the new growth and a t a closer inspection i saw flower buds on the small branchlets. Almost all of them have tiny round flower buds, is this a weard behaviour?









Heres a double leaf from the second plant

Temperate Fruit Discussion / Akebia quinata flower morphology
« on: May 17, 2022, 01:53:00 AM »
My vine just flowered a week or so ago, and one interesting observation i carried.....most of the flowers like 99% were small in size, but there were also two that were way bigger that the rest. The two big ones were like a steroid laden version of the rest ,and had somewhat of a star shaped ovule i quess at the center.
So are the big ones the female flowers?
The smaller i would assume were the male ones, and they had pollen carrying organs, but without any pollen that i could see...
Wanted to artifficially pollinate the bigger ,supposedly female flowers ,but there was no pollen....
Will they set without pollination ?

Well just checked in the web and yes, the bigger ones are the female flowers...also read that the plant needs cross pollination ,so i wont get fruit this year, hopefully my other plant will get big this year and flower next, so they can pollinate each other....

Tropical Fruit Discussion / A watermellon question.....
« on: May 13, 2022, 02:37:26 AM »
I want to try my hand again at watermellon, they are generally hard to grow here out of a greenhouse, problems like too much moisure and desease becouse of it are guaranteed. So i was thinking of making some planting pockets with regular white or black nylon bags, the ones that are maid of weaved strings. I have planted plants in the past in this and it has provided good drainage and also air. I will cut the bottoms of the bags and place them on open ground so they can root down readily, when they are ready to. The place i want to plant them is wetter then needed most of the rime ,so thats why i want to make them like raised beds from those cheap nylon bags.
I will also cover the whole bags with somethink when there is too much rain , so they do not get saturated.
The "pots " will not be moved ,so logistics is not an issue!
What soil are u using when growing watermellons, like not brands becouse i will have difficulty finding those, rather texture and general ingredients that u add etc ..?
What do u think , and thanks ?!

Sorry for the off topic! I am searching for the name of the desease/ fungus for several hours now . I just found it on some of the stems of my weaved willows, it seems to apear at places which are little scratches or cracks in the bark, dunno it the cracks are a symptom or the way the fungus got in.... i have some severe cuts on some of the stemms ,and those big wounds do not have this. The visible orange part is dust-like in texture.
I desected one of the ill spots and the fungus is only present just near the crack or wound and the bark tissue is sorta orange colour which means i think it is infected and not just a surface thing.
I will spray all of the plants with a fungicide later today ,and i wonder if i should like cut the damaged parts and spray then or just spray??
If anyone knows what this is ,please share and thank you !







As a side note i think it would be helpfull to have a place on this forum to comment and post about decoratives and other non fruit related plants, if thats possible, like a generall ornamental plant forum ?

Tropical Fruit Discussion / Time for air layering ??
« on: May 05, 2022, 02:27:56 AM »
Hello , my tropicals in the greenhouse have started growing at a steady rate, so was thinking of setting some air layers early to have them root nicely by the end of summer. Planning to airlayer catleyanum guava, regular guava and avocado. Any tips ??

Found this for sale, red its a sour type fruit. Is it worth growing this, how is it tastewise ??

Tropical Fruit Discussion / Heat mat experiences
« on: April 16, 2022, 05:30:11 PM »
I bought a heat mat theese days ,to help germinate some cacao seeds. Its just the usual type one, cheap and with no controller. I tried it for one hour and at room temp it got quite warm, at the surface close to 40C. Funny enough ,i find myself scared and cautious of using it since i have read at places people had bad experiences with them.

Anyone had a modern horror story with a heat mat ??

Tropical Fruit Discussion / Grafting roots to aid with air layering
« on: April 13, 2022, 02:11:13 AM »
So this is complicated, but for plants that are known to root via airlayering, but are slow or hard to do so like my carambolla, i was thinking of trying to graft a few roots on the stem and leave the joining part away from humidity and water. Anyone tried this?  I'd like to hear some feedback on this ' thanks !!

Temperate Fruit Discussion / Cherry scionwood question
« on: March 28, 2022, 10:09:06 AM »
Hi, i took some decorative japaneese cherry scions and most of the stems have flower buds. I have some growth buds that i can use but was wondering if i can also use the ones with flower buds. Are there any miniature growth buds hidden in the flower buds that can wake up after the flowers finish,or i was thinking of removing the individual flowers after they gain some size but before they flower, to promote any such growth buds to wake ??
Thanks !!

Tropical Fruit Discussion / Forcing baobab seedlings to leaf out ???
« on: March 08, 2022, 02:31:36 AM »
Hi, so i have those two dormant baobab seedlings with no leaves, one of them shed its leaves in nov- december , the other one sometime January i think, both of them are now naked.  The branches are green and there are buds visibl3 at the tips but they are not swelling. I am holding off the water on them to not rot them, the soil has some moisture to it 
Will they leaf out on their own come spring or should i force them somehow.

 I am wondering when should i start fertilizing my gh plants, all fruit plants. Was thinking around the end of february, at that time i assume i wont need to heat inside and the night temps outside should be above zero. In the last few days the day temps in the gh do get around 30c. Night lows are around 10c +- 2c.
That said ,alot of the plants are pushing growth since new year ,so i may have ro start earlier ??

Tropical Fruit Discussion / Can i root a papaya cutting ???
« on: February 04, 2022, 12:44:04 PM »
Hi, this is my papaya from the gh which roots rotted away and today i salvaged the top portion since it was a goner anyway. Can i root it, how should i proceed to do so? Right now its sitting in a glass of water with some rooting hormone added.
Thanks for the heads-up !

Hi, the rats damaged my opuntia a few months ago and today i saw that the damaged places are partly rotted and jenerally very squishy and soft. I already cleaned the spots and detached the top part of the plant and will let the wound heal a bit before i replant it. BUT i do not know if the whole pars as it is will be able ro root or i may be better off to cut it into smaller peaces and work with those. I would like to root the whole section if possible...

Can anyone provide a guide for the ripening and blooming times for different tropical fruits that are grown in northern countries like here in Bulgaria? Interested in species like guava , cherimoya ,avocado ,coffee, dragonfruit and others you have information on.
Is there a relation with the earths  paralell lines, can u tell by your geographic coordinate that a sertain species will fruit or bloom at a sertain time, given that most of their growing conditions are met...
I'd imagine latitude will also be a factor ...
I am talking mostly about greenhouse growing, but if there is a difference between a gh inground plant and a potted one that gets brought inside for winter, please point it out !

Thanks for any input !!!

Tropical Fruit Discussion / When to pick those guavas ?
« on: January 09, 2022, 08:18:26 AM »
Hi all !! Are theese babies close to ripening ?? Asking since the mother fruit that i got the seeds from was bought green like they are now, it was pinkish inside but was probably way underripe. Am i wating for a all yellow colour on the fruits? They have began to get paler green/ yellow but are still hard and i do not sence any fragrance to them. Thank for the feedback.

Temperate Fruit Discussion / Sorta off topic air layering question
« on: December 28, 2021, 05:25:52 PM »
Hello, i will be setting a few air layers on field maple, hornbeam and elm trees for starting bonsai, and was wondering what is the best time to set them? Read that its best to wait till the plants have their first set of leaves hardened, but as awlays i would like to hear an first hand experience.
Can i set them before the trees have leafed out ??
Thanks a ton !!

Tropical Fruit Discussion / Mid-winter greehouse update
« on: December 25, 2021, 02:37:21 AM »
Hi everyone and happy holidays! Just making an update on the happenings at my gh as of today. As jenerall all is well ,excluding two salak casualties, and one vanilla orchid that had rotted at the root area, but is now inside and will be nursed back to health.







Heres the gh from the outside and a an group picture of the inhabitants.


My pasiflora decaisneana, having some new growth .



Here u can see seedlings of longan, oranje jasmine,  lychee, carob and one lemon guava at the back.





Heres a cumquat and pomello with some fruit, both of them are shedding some leaves... on the pic with the pomello u can also see my surinam cherry ,one very small pineapple, ant two aloe vera species.









Next are my tropical guava seedlings, 4 plants in total, 2 from a big fruited type guava and 2 from a smaller fruited one. Both of the ones that came from the bigger fruit are fruiting this year, one of which has quite big fruit which i think will be starting to ripen soon. In-between  them there is a half dead papaya, i had 3 of them , will prolly lose this one also, i think the soil temp is too cold for them.


Pachira aquatica/glabra , no idea which one of those...







Curry leaf tree/ muraya koenigii ,one lemon guava which is hardly visible, and my strawberry guava which has alot of new growth and some flower buds.








My two cherimoya seedlings, the one next to the wood stove got defoliated due to heat and has some new growth and two flower buds. Happy to see this, hopefully in spring there is alot of flowers on both of them.


Jackfruit, longan and a super dwarf cavendish banana.


Lemon guava


Lemon grass, this shit is amazing, gives such a nice flavour and smell to dishes, way better that lemon itself.








My 3 avocado plants, all of them are making new growth constantly.



Mango seedling


Camelia sasanqua, will use it in future for tea


Pasiflora ligularis coming along nicely with new growth, following a hard pruning.











Dragonfruits, also making new growth, only the grafted megalanthus seedling are sitting still.


True Cinnamon also making new growth since october, infront of it a pineapple with a rotten center.
 

Coffe arabica


Monstera deliciosa also growing at the moment...




Carambolla shedding most of its leaves , in some places i read that this is normal with them in colder climates.

Thanks for stopping by , for everyone that has experince with growing those species in a similar climate to mine, 6b -7a and colder , in a greenhouse, i would love to hear your reccomendations on keeping the plants alive trought winters, thanks !!

A long read for everyone interested in the effects of climate change on tropical fruit plants. At page 45-46 starts the more interesting part ,in which particular species's native range temperature conditions and reactions to sertain temps are described.

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........

Tropical Fruit Discussion / Do tamarillo ripen off the plant ??
« on: October 21, 2021, 12:42:10 PM »
As above, i have those fruit, which i harvested from my plants that i brought inside the basement for overwintering. I doubted that they would ripen on the plants in the dark cold basement ,so harvested them and placed them in a paper bag along with a few apples. Most of them have a tiny bit of colour at the bottoms, some of them have a bit more colour than others,yet some do not have any. I would assume all of them look like the cut up one on inside. <br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />

By the way ,does anyone reccognise the varieties from the fruit pics ?? <br /> <br />
