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?

Nop, the leaves are from the large tree you see above with the green fruits hanging. I just picked the largest one I saw and took some photos.

This year the tree is completely covered over by a passion fruit vine so I need to cut out the vine so my pomelo can get some sun light.
Yeah, i ment if the leaf was from the tree, but from a water sucker, which is a strong vegetative shoot. Usually those bear bigger leaves, compared to the rest of the plant.
I think i know the answer to why you have such huge leaves , your passion fruit vine is making your tree defficient in light, thats why it make big leaves, bigger leaf area harvests more sunlight energy.

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 !

Never seen such big leaves on a citrus. Was the leaf on a young strong shoot, growing in the shade ?

Tropical Fruit Discussion / Re: What triggers flowering in tropical guava?
« on: February 02, 2023, 04:42:29 AM »
My seedling guavas flowered for the first time at almost 2 years of age. I get flower buds at some or all of the new growths at times, other times they dont make any. I usually dont prune them i let the growth make 2-3 sets of leaves and then pinch the top. That said they are getting out of hand sizewise so this spring i will be pruning them back a bit.
For me it seems like a plant that has a chance to flower almost every time you prune.

I am interested in the idea of plucking the leaves, reminds me of the procedure i do on my cherimoya, will probably try that.

Tropical Fruit Discussion / Re: Bees in greenhouse? What have u tried?
« on: February 02, 2023, 04:28:02 AM »
From my limited knowledge regarding bees in general, for a closed environment i think you should look into the tropical or small familly/stingles bees. Ive watched videos of such species, their colonies are nowhere near as big as europian bees for instance. For a greenhouse a standart europian bee colony will get starved to death, i dont know if bee colonies grow proportionally to their environment, so it may be possible to raise them with a limited amount of food/flowers.
For the passion fruit i would suggest to do a hand pollination ,if you have acess to the flowers. In my opinion thats the 100% sure way that u get alot of fruit, that will be worth the trouble to grow a passion fruit out of its native climate.

Interesting, seems to have some Poncirus and probably coldhardy genes. Interesting how hardy and how the fruit quality is ?
It seems hardy enough to survive the winters in my basement, with close to freezing temps, and has froze in its pot several times.

Sure here it is, i found just 1 of the bilobed leaves, the other ones must have fallen off. It is a seedling from a standart white fleshed pomello, the only pomello seed that i have ever found in store bought pomello.

Plantinyum, chimney fires are scary, were your babies all ok? How far down does your ground freeze? Could u dig deep around the periphery and place tubes for an earth battery air exchange? I have no experience with this, and have now idea what happens if the water table is high.
Well the times where it got fire i was there and was shooting some water on it on the outside, which didnt really help anything. On the inside the metal chimney would get all yewolly- orange, hot as hell, of course it would burn and dessicate all livving things around it.
Our ground rarely freezes lately, we are yet to have it freeze this winter. I can do the pipe earth battery thing, but i dont really need it now, if i want to have a warmer temp inside i can just add an additional radiator ,which i already have.  Will have to disterb alot of plant roots too, in my case now, when i have  a good heating system, i wouldn't do it.
The water table here is quite low i think, ive never hit a standing water anywhere. It is a seasonal thing probably.
Yes such tubes into the ground would fill with water ,to where the water table is. People do wells this way.

Yeah i am not fixed on the idea of fruiting the seedling, i will graft it with my other 2 pomello varieties, since i see its growing vigorously and seems like a good rootstock . I hate flying dragon rootstocks, stunts the plants really bad in my experience.
I suspect mine a hybrid since it pushed out several bilobed leaves, probably some trifoliata gene in there.

Pomelo do not come true from seed & also require a large node count before they will flower. In ground they will take 5+ years in perfect conditions. In a container they will never flower or produce fruit, that's just the nature of the variety.

I have seen a number of containerized pomello that fruited in containers, in Bulgarian citrus and garden forums, people manage to pull it off. They are grafted on dwarfing rootstocks thought ,thats may be the reason why they manage to fruit them.

I also have one 3 year old seedling , a single seed in a store bought fruit, planning to graft it with my standart and red pomello this summer, will also let a original branch to grow probably. Its quite a besutifful plant, my healthiest citrus by far.

I removed scale successfully without killing my plant by doing this:

get a bucket of water and add a little bit of high strength rubbing alcohol and get a q-tip, find some scale, and test the alcohol strength. if they turn red in 1-2 seconds, its probably strong enough. just keep testing back and forth back and forth until they die really quickly, but not immediate (because that means its too strong and will probably hurt the plant too)

then douse a papertowel in it and coat every single surface above and below, extremely thoroughly. I find that just spraying can leave gaps sometimes whereas wiping you can really get into the crevices of new growth. Then spray off with water

Took me like 40 minutes for a <2 foot tall plant, but it did seem to work
interesting technique! I can see it being alot usefull for the nymphs or whatever their babies are called, like the big ones i could just scrape off but the alcohol will also kill the very small ones.

 I have been an indoor grower for like 5- 10 years since i started to maniacally collect whatever tropical fruit species i could get my hands on. Here in zone 6- 7 at 830 m above sea level, growing tropical stuff is hard, althought i have a greenhouse now i still have the house chock-full with plants, placed near the brightest windows. They really hate it in winter for alot of reasons, lack of light being the major one.
I will say that the ones that are in the greenhouse / inground are doing fantastic. I see most people here that have greenhauses are having their plants stay in there potted. I hardly have anything potted in the gh, only a few plants that will go out in summer. I hate having potted stuff in there since i made it with the solo reason and idea of everithing thats inside to be planted inground.
The walls are 20cm thick,60-80 cm deep into the ground on south and west side, and around 40cm  on the north and east sides where i have it incorporated into the pathway. The walls
have 5cm thick styrofoam on both sides. All this was with the idea of keeping the internal soil isolated from the cold soil outside.
Construction is a standart greenhouse one with square metal
pipes 2 cm width, 1mm thick, galvanized. The policarbonate is 4 mm thick . Its ment to sustain a 80 kg snow load per square meter(its 3 on 4 m), thats what i remember from the instruction list. Snow hardly ever persists on the structure, the form combined with the warmth that comes from below quicly melts and slides it off. On the outside of the policarbonate i have 1 sheet of big balloon bubble wrap, on top of which i have 1 layer of clear nylon. Those 2 additional layers ive attached to the structure via the same screws that are supporting the policarbonate.ive NEVER had a problem with it blowing off , the way ive fixed it is keeping the layers nice and tight on top of each other. Yes, water gets between the layers at places, also inside the bubble wrap, but ive never had it green up or get dirty becouse of this. Green algae i have a lot of on the inside of the greenhouse, mainly on the walls.
Heating- last year i was heating with a wood stove, what a horrible experience that was, dont reccomend, although i pilled my plants trought winter fine i needed to stay till late evening to set the fire so it would last the night. I also almost lit the greenhouse on fire on several occasions, on which the chimney got fire, as i said, dont reccomend!  This year i made a radiator heating system, i dug a 20 meter long, 60 cm wide, 80 cm deep canal for the pipes that cary the water from our fire place. Did the digging myself and at one point was questioning my existance, now im real happy i did it though as i knew the alternative was nasty aff. The inground pipes also were insolated with a very thick 20+ cm stirofoam on every side, filled the crevices with fixing foam.
I have 3 radiators, 1 140cm by 60cm and 2 60 by 80 cm. They are sufficient at this point , succesfully keep the inside 15 to 20 c at -7c outside temp.
The 2 barrels i use for wattering, i fill them with water from my ponds, in a matter of a day the water is warm and ready for use, they also add a little of a buffer heat as they are heated up by the radiator.

Are the quails food or pets? Try neem oil because it is not toxic it just smells bad.

Does neem work on scale? I ve spraied neem before, my cherimoya plants hated the stuff. If its effective against them i can spray with it, the citrus did not show any sings of damage.

I bought 2 snonna reticulata seedlings in individual pots, those had already several leaves on them, in one of the pots there was an additional seedling that was decapitated. From my experience with cherimoya and with this particular reticulata, if the decapitation happens below the point where the cotyledon leaves were/are, theres no chance for sprouting back.

With that much fruit it's no wonder the tree doesn't bear the next year. The way to solve alternate bearing is to thin the fruit. That also often results in higher quality of the fruit that remains after thinning.

I was just going to say the same, alternate fruiting is what happens when a tree has a load of fruit one year, and none or a small quantity the next. Just thin the fruit as fruitnut suggested, that will brake the cicle.

Looks great!

Thanks! I'll keep it updated trought summer!

I canít get rid of scale and donít understand it. My large red lime and Meyer lemon were completely free for years while others were infested, now this year only they have it. Yeah Iím stuck using hose in summer and spray bottle with soap/rubbing alcohol And a toothbrush in winter. Iím gonna try mass rearing of lacewings next year, scale destroyers donít work at all for me (tired them twice).

i think i will start to just scrape them off from the leaves occasionally,  without messing with wiping the leaves..eventually the life sicle should be interrupted. It just takes alot of effort and persistance to do it this way..

 Havent had the fruit of feijoa,
I have 3 feijoas , none of which have fruited yet, they are reasonbly big plants. The one it the greenhouse has around 20 flower buds forming right now , the other 2 that are potted havent bloomed yet. The poted ones are an unknown variety, the greenhouse one is Jemini. Last year i self pollinated the gemini, didnt form fruit. I hope they all bloom in spring at the same time so i can cross pollinate, butthis may be challenging as the greenhouse one doesnt experience any winter temps whatsoever, doesnt get below 10 c in there, and rarely does it get below 15c. The potted ones are in the basement at much colder temps.

Nice greenhouses and plants!

Daintree, i am jealous of your cacao, bananas and the rest place that you have in there! The parot has a very nice colouring.

Tropicaltoba, supposing that you have planting space outside the greenhouse, why dont you plant the stonefruit outside? Is it too cold to grow peaches there outside, or you just have space limitations in the yard?
I have thought about a similar thing, supplying cold to my feijoa in the gh. Ive thought about enclosing it in someking of a box, and opening a small window in the policarbonate, to supply the cold needed. I think you could do a wooden or other box around the peach trees, and install small windows to supply the cold air. I dont know your setup so excuse me if this is impossible to do...

Ive seen parasitic wasps in my yard, infact i think i saw their larvae on 2 occations, 1 time they were parasitazing a caterpillar,  the other time i found a live ground worm that was full of oranje little worms,this may have not been a parasitic wasp, dunno. Their life sicle is badass!
When i have aphid infestations outside, usually a strong poppulation of ladybugs gets established, cant beat ladybug at eating aphids, their larvae are the best thing that can happen to a garden.

To be fair, my plants leaves/canopies in the gh are above the line that the quail can reach, mine seem to nibble at the banana pups,  those juicy big leaves do atract them somehow. Strangely they dont bother one potted surinam cherry that has its branches crawling on the ground, not a single nib on it so they do have preferences lol.
 I also have scale on my citrus there and it doesnt get phased by any insecticide ive tried,nasty stuff. Only thing that works for me ( havent tried imidicloprid ) is removing them manually  and ultimately spraying with a insecticide after that. One of my pomello is clean after this,still need to do the lemon which i badly infested.

Thanks for the suggestions, the ground here freezes to 6-8 feet here so Iím gonna have to start working out to get my shoveling muscles ready for the spring. Iíll probably pick your brain closer to the spring in an attempt to minimize failed pond experiments.

No worries, i'll share what i know !

Tropicaltoba- Hahah ;D , if you have the space ,make one, it doesnt have to be huge u know, just make it deeper since your in a cold zone and fish like to have a deeper place to go to ,when its very cold.
My ponds look like nothing right now, they look spectacular in summer with all the vegetation, waterfall running and water lillies blooming. Its a little more work in the start untill the water has circulated itself, after that its on a autopilot mode.

i keep goldfish and some native species

Plantinyum, what native Bulgarian fish species do you keep ? Just wondering what they might be ?

 We have Carp, Tench, Redfin Perch ( Perca ) and Rudd/Roach introduced to Australia.
I only have two wild species in the ponds, one is crucian carp, which is kind of an invasive species in our area. The other one i dont really know the name of it, its a small elongated fish, dark grey in colour with quite prominent protrusions on the sides of the gills/head. They may stay so small due to the confinement of the ponds.
I also had wild juppies at one time, those died out the first winter, they are native in some southern areas of my country, invasive as f**k.
I also have 2 big lake clams in the bigger pond, i should get more of those for both ponds, they seem to love trailing trought the muck.
I would love to really stock the ponds with all kinds of native fish, but they are too small for heavy fish raising. Will stick with goldies since they are the most friendly and beautiful to look at, native fish are too shy, thought my crucian carps do eat food from my hand at this point.

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
