Tropical Fruit Discussion / Cherimoya seeds as insecticide?
« on: March 17, 2023, 03:26:30 AM »
Has someone used the crushed seeds of cherimoya to make an insecticide? Can you share the recipe on how you did it?
Does it have any worthwhile effect and on what pests is it most effective against?
My cherimoya started fruiting and i have a load of seeds that i dont know what to do with, i would like to try to make this insecticide but not without first consulting the tropical fruit gang haha  ;)

Tropical Fruit Discussion / Cherimoya bonanza
« on: March 05, 2023, 07:01:47 AM »
Cherimoya season here in Bulgaria is in full swing haha 😂
Ive been harvesting the fruits of my 2 greenhouse  plants for a week or so. I was puzzled at first as to when to harvest, but think i found the best way that works for me, i bagged the fruit with organza bags, tied them to the branches. Now as the fruit ripens they stay for the longest possibl2 on the trees, i just inspect them each other day for softeness, by the time they are soft they have been separated from the stem end and i just untie the organza bags and harvest. Then i leave them for several days to ripen further, i found that they are very good tasting when they have that watter soaked look to the skin, as like they were frozen and thawed.  I will try to leave some of them to ripen further to see if they become better.
Taste profile is sweet, standard cherimoya taste, cant really find difference compared to the very good ones i sometimes find in the store, thought most of those are not as tasty as my homegrown ones. The smell of the fruits strangely enough reminds me of maybe dark chocolate.  The size of the fruits is satisfactory, although i think with some heavier thinning there is place for improvement.
Overall first cherimoya fruits ,from seedling plants ,took 5 years, it was wort it! Both of them have nice flavoured fruit.
One drawback is, they are quite seedy.

Tropical Fruit Discussion / Variegation spurt on a strawberry guava
« on: February 27, 2023, 12:39:15 PM »
Found this interesting branch the other day, it is a top branch where 2 oposite buds have sprouted with variegation, both the leaves and the stem have the variegation. It is only on this one branch, none of this on the rest of the plant.
There is a flower bud which also seems to be white.
I will monitor the new growth of this branch and if it keeps the variegation will try to air layer it.
Just noticed on the pic that the underside of the leaves are also white, compared to the regular one in the photos.

Tropical Fruit Discussion / Carica papaya vs Carica pubescens
« on: February 12, 2023, 05:40:39 PM »
Can someone compare those two species to each other, i am interested in fruit taste, ease of growing of C.Pubescens, compared to C.Papaya. Ive grown regular papaya and its not the easiest of plants, i am germinating right now regular and pubescens papaya seeds, i will have 2 new spots to plant papayas in the greenhouse. I am interested mostly how does the fruit of papaya pubescens  compare to regular papaya, like the small fruited solo papaya.
I would like to plant two papaya mounds in the greenhouse, so i womder if i should leave space for pubescense or just go with the regular one.

I have 2 monteras ,inground in my greenhouse. They are wanting to grow up wright but due to space limitations i would rather train them to grow along the ground. Do they fruit better when grown vertically, towards where theres more light, or do they fruit as well when creeping along the soil?
I would ultimately want to have them as creepers, but if most of you suggest that they fruit better when vertical in the sun, i will have to make some space and trim my other plants so i can fit the monsteras vertically.
Please share your experiences and observation on the species, thanks!

So i red that cherimoya needs 50 to 100 hours of temps around 6 C , anybody growing cherimoya in places where it doesnt drop below 10C and still get fruit?
I am asking since my plants are greenhouse grown, currently at temperatures of around 15C in the night to 25 C in the day. They are currently holding fruit which is starting to change colour to an extent. Is it ok to have the plant hold fruit while it experiences such low temps? I can manipulate the temperature inside to get to around 5C  by shutting off the heating sistem and i was intending to do this after i harvest all the fruits, expecting them to come end of feb and march. So is it a good plant to wait on them, harvest them and if i pick the last ones in the end of march i will still have the cold outside temps to allow to have colder temps inside also. This will be perfect as i am also planning to prune and strip leaves somewhere in april, so suppliyng some cold in march?

Temperate Fruit Discussion / Peches/nectarines in pots?
« on: February 02, 2023, 03:56:19 PM »
As i dont really have space for much inground trees, but i do have one nectarine that has the best nectarines that ive ate, i want to propagate it and grow a few plants as potted specimens. Didnt find much info regarding potted culture of peach so i post here as i value the first hand experience much more anyways. I already have 2 grafted plants that i did last spring, grafted onto wild plum rootstock. Dont really know if this graft combination will be ok in subsequent years.
I plan on having them in bigger and bigger pots as they grow, finally planting them into gigantic 100+ liter pots, which will stay outside trough winter.
Please share your experience, thank you !

Temperate Fruit Discussion / Strawberry tower
« on: January 26, 2023, 02:32:46 AM »
This turned out very nice, i would like to do several of theese, but dont really have space so may do 1 more at most. The idea is to have more space to plant the strawberries, they wont shade themselves as much when grown vertically. I would imagine that the fruit would also be alot easier to pick, there is enough space for it to hang down. I will paint the green plastic with brown paint, as its kinda my main colour of the structures in the garden..I cant wait to plant them and hopefully to have a nice crop this year.
Its 120 cm high, i am thinking how cool this would be if it was like 3- 4 m high lol

Tropical Fruit Discussion / New summer time passion fruit trellis
« on: January 21, 2023, 04:02:49 AM »
I did this so fast, usually i plan for such things for like at leas a month, pondering about..... this time i just had the idea in the evening and next day i was already doing it.
This trellis will be perfect for the summer growth of my passion fruit plants, i have 1 purple edulis and 1 decaisneana in the greenhouse, they are growing vertically on the wall of the greenhouse, fixed to a aluminium fence. This growing possition is not optimal in any way, but i am forsed to grow them like this due to space limmitations. They cast alot of shade on the other plants that way.
Anyway, with this new setup i will guide the new growth trough a hole at the top of the greenhouse, i will remove a piece of the pollicarbonate in spring/may and let them roam outside.
The purple edulis i'm sure will really apreciate the new space, ive grown the purples outside in pots and in ground trought summer with no problems, the decaisneana may not grow as good there, since i think it likes a little more shade and a lot more humidity . In fall i will have a problem thought ,i will have to prune and take the rest of the plant inside the greenhouse, i just hope that whatever fruit sets it ripens before that point, as messing with such long and tender vines, carying fruit will be a nevre braking job.
Here are the plants:

This is the trellis :

The pics are not too clear, but thats the best i could do ..

Temperate Fruit Discussion / Overly warm winter, a double-edged sword?
« on: January 18, 2023, 06:29:05 PM »
This winter up to this date is probably the warmest winter that i remember. Lowest temp we had was minus 7C, 95 percent of the time weve been frost free, cant even talk about a frozen ground/soil, which we shouldve had till now. The warm temps are deffinitely helping with the zone pushing part+ its very easy to keep my greenhouse sufficiently warm.
On the other part i did spot some worying singhs yesterday, blueberries along with my almond tree are starting to show singhs of waking up, a slight bud swell, which should have naturally happened in middle to late march. 
As much as i love the warmth and being able to do activities outside , i hope the weather normalizes and gets colder or else plants will have a ruff spring start...

Tropical Fruit Discussion / Homegrown guava taste review
« on: December 30, 2022, 05:08:33 PM »
So ive been enjoying theese several fruit that this plant in particular had, i am still experimenting with the harvest time, but this fruit in particular i think  is at an optimal ripeness.
Weights 250 grams, guite a big one, all of them were as big or bigger, around 8 fruits this year on the plant.
Smells very floral and sweet, almost like a perfume on the outside. When cut open the smell is somewhat different, cant really describe it.
The flavour is very good, not very sweet but alot of complexity to it, tastes like a fruit salad, i'm terrible at this lol, sorry! The inside part has the texture of soft butter, its sweeter, compared to the rind, which has the benefit of being juicier and more flavourfull. Overall, i really like this particular seedlings's fruit, i just hope for more sweetness in future's crops.

Just read one cacti thread and thought what if i graft a few opuntia ears on my dragonfruit cactuses. My dragon fruits are very big plants, i have alot of material i could graft on. I want to add opuntia to my greenhouse ,but if planted in the soil it will be too moist and shady for the plant, i would like to add a few grafts at the top of my pitahayas .
I think one major problem will be the weitht of the opuntia grafts, as they start growing, but i could tie them to my greenhouse  structure, or policarbonate somehow, that way they will get alot of light and hopefully produce fruit also.
So yay or nay?

Tropical Fruit Discussion / Avocado leaf problems
« on: December 21, 2022, 05:11:27 PM »
Hi, my avocado in the greenhouse is having some of its leavs drying in 2 different ways.

Some of the leaves are getting brown from the base/ center of the leaves out.

Others are having necrotic spots spread on the leaves, they appear at random places on the leaf, thought usually from the edje towards the center. First theres a green dead spot, then becomes brown and turns to a crisp, after that the spot just gets bigger via the principle.

And then i also have those leaves that just turn a light yellow/green colour and fall off.

Could it be from too much heat? I have radiators working in there BUT the damage started before they were put into use. Soil is slightly moist to moist. I  recently sprayed with fungicide and pesticide, but that was also after tha occurrence of the problem.
Last year i didnt had such a problem on it, rhought the greenhouse stayed alot cooler.

Forgot to add the overall pic off the tree, doesnt look so bad...

So i bought a few of theese species's seeds, they are all dried, the seller said they are from this year, yeah  it doesnt really sound incorouging. I justhope a few of them pop up, right now they are soaking in water.

Anonna squamosa
Manilkara zapota
Carica pubescens
Anonna muricata
Mimusops elenghi
Garcinia dulcis
Uvaia rufa
Flacourtia indica
Antidesma something....
Nauclea latifolia
Any chance some of theese to sprout after being dried out?

I aquired a few quails last month, i am keeping them in my greenhouse. I havent had sprayed the plants in there for like 2-3 months, so i sprayed two consecutive days with fungicide and a pesticide becouse i found some aphids on the plants, there are also some sighns of mites.
The birds i relocated into a cardboard box before the spray, everything is dry inside the gh now, i plan on releasing them back in this evening which will mean that the gh had solid  days after the final spray ,to dry out.
The soil of course got moist from the chemicals and that is what worries me thw most.
Does anyone else that keeps animals/birds in their greenhouses spray their plants from time to time? How do you proceed ,in order to not poison the livestock?
I find that i have to spray at least periodically, in order to not have a pest infestation, which if happens is a nightmare to erradicate, especially mites.
Will i be ok with releasing them back today, or should i wait a bit longer ? I should say that the greenhouse does still have a bit of a smell from the chemicals....

So my guava plants are having some fruit thats ripening, i awlays have the feeling that i pick them a little underripe.   Cherimoya should be coming in february, so my question regarding those two is...
Can i bag the fruit that close to being ripe with organza bags, tie up the handles to a branch and just wait for the fruit to detach from the stem on its own? Is this the way of getting maximum ripenes?  I saw this trick on one youtube channel where the person bagged the cherimoya fruit and waited for them to fall off in the bags.
Anyone doing/done this?

« on: December 16, 2022, 06:22:42 PM »
Hi ! Thought to do an update on the tropicals ...we are having a mild winter so far.
The wood stove which was the heating system from last winter is a hystory, the new radiator based heating system is working fine for now, keeping things warmish at 15 to 20 C at night.

Tropical Fruit Discussion / Air layering guava in winter question
« on: December 16, 2022, 01:51:44 AM »
Hi ! I have 4 regular guavas in my greenhouse and i am planning to remove 2 of them to make space for other exotic fruit plants. Is now a good time for air layering guava? I want to make several air layers on them, before i dig the whole plants in spring. The greenhouse is heated and for now it stays solid above 10C ,around 15 to 20 C in the night, in the day it is usually warmer. The guavas are growing at the moment, not as fast as in summer but they are def having new growth.
I want to do this now since i want hopefully, to be able to dig them up around may or june, i could dig them up now but i will be sacrificing alot of the branches since i cant dig the rootball big enouth, due to closeby plants.
What do you think? Thanks for your oppinion !

Temperate Fruit Discussion / Strange bumps on a plumcot trunk
« on: December 10, 2022, 12:51:12 AM »
I have this cross between a plum and an apricot, its a grafted tree from a nursery. Last year it started to form theese bumps on the trunk and along the main scaffold branches. I cut one of them ,there wasnt a worm or other insect in there. They are also not full of resin, ive seen resin pockets just under the bark on most stone fruit species, those are definitely not that
When cut they are firm and look like they're not just a bark formation, but rather have a hardwood core.
It's interesting that the rootstock part doesnt have any of this, they are forming at the graft line and above.
Anyone know what this might be ? Thanks !

I know some of you raise quails in your greenhouses, i looked up old posts but couldnt find information regarding whether quails eat and could damage plants. Has anyone of you had problems with them destroing your plants?
My uncle will be getting me 5 quails, probably the common ones, in a few days . Should i put nets around the bases of the plants?
Particularly worried about my dragon fruits as they arent woody and would be easy to consume...
Also i hope they dont eat all of the earth worms that i have in the top layer of soil...

Well ,from one problem to another....i was wondering why my apricot trunk is all cracked and full of deep crevices ,well a week ago hapenned to look a bit closer and found the remaing/discarded shredded wood  piles all over the trunk of the tree. I assume that i have bark borers in there ,probably the same ones that i found on my cherries.
I do have them in way smaller amount than in the apricot and i actually extracted almost all of the ones that i found on the cherries, they are like little caterpillars that bore into the cambium, just below the bark. They are actively eating the live  bark/cambium layer.
What can i use to control such pests, i could spend several days extracting the ones from the apricot manually but i will damage all of the living bark thats left, its that bad!
How do i deal with those ?
Thanks alot !

First, i am sorry for the off topic , i posted about the same mushrooms last year, in the temperate fruit section and was left without answer. Looked pics online and didnt really saw the same ones that i have....
They are growing in big numbers in my blueberry patches, they seem to like asidic soil but i think are growing without a host. No pines or big trees around, only fruit plants like apple and stonefruit, along with the blueberries. They are growing at clumps as shown in the pics. I just want to know if they are edible or not...


Tropical Fruit Discussion / Latest blooming loquat varieties?
« on: October 17, 2022, 11:55:23 PM »
Hello, one fellow fruit geek is interested in which ones are the latest blooming loguat varieties. The goal is to grow the variety/ ies here in BG, so a cooler climate asks for a plant that will flower at the end of winter and begginning of spring, which is end of march trought april. If theres one that blooms even later, like may, that would be great.
He first wants to know the names of the varieties in question and will do his research on them, later he said he would be looking for plants or cuttings for grafting, once he's sure about the varieties.
Thanks for helping out !

Tropical Fruit Discussion / What variety/species of anonna is this?
« on: October 12, 2022, 10:42:46 AM »
One woman from BG is selling seedlings from this, shes labeled it as a cherimoya but the leaves on them are more pointier, just like the ones on the tree with the fruit, which doesnt look like a cherimoya to me. She said that the seedlings are from this particular fruiting plant. I ordered 2 and just want to know what i have, is it a sugar apple instead of cherimoya?
The tree is located somewhere in Miami ,Florida, incase this matters .

Tropical Fruit Discussion / A rather awkward fertilizer opportunity
« on: October 11, 2022, 10:26:53 AM »
So, prepare for this one! I found a bunch of very old bags with bones in the forrest. The nylon bags they were dumped into have pretty much degraded or are degrading so this should have happened at least 4-5 years ago.
The bones themselves also look old, they are all the same and look like the bones u get in chicken legs, i can quess they are from chickens.
I wonder if i could or should take the bones and hammer them and use them as a bone meal fertilizer. Are there any risks with deseases with old bones? Again ,they are all the same tipe, no spines and other nasties, they just look like someone just cooked a bunch of chicken limbs and discarded the remains.
Is this a good opportunity ?
