Hello and sorry for this off topic question, i just cant wrap my head around as to whats going on with my decorative willows. They are having some problems with their leaves, the leaf starts to lose chlorophyll,  gets a little yellow at first, then starts to dry up from the edges towards the center. The closest thing that i found in the web, which the problem might be is pottassium defficiency. Its only happening on the oldest leaves. Plants look lush and green and healthy otherwise, but i know something is not wright. I am really carefull with the wattering, let them dry a little before the next waterring, they do not dry up to the point of wilting. Havent fertilized heavily also, and i also do not have it on all of my plants, my 2 year old ones(established plants) do not have it at all. Can someone help please?

Temperate Fruit Discussion / Nectarine problems, i need your advice!
« on: April 27, 2023, 11:25:17 AM »
My beloved nectarine is acting funky lately, the leaves are super thin and do not expand as they should. Ive sprayed several times over winter with copper fugicide , that was before it woke up. I dont think this is peach leaf curl as there are no red bumps on the leaves and the plants leaves are all looking like that, whereas leaf curl affects mostly portions of the tree, when it is just starting.
I gave the tree granular fruit tree fertilizer with an even number, i think 15-15-15.
Could i have given the tree too much fertiliser? I have also sprayed last week with fungicide and incecticide, but i doubth that whats happening is triggered bu this, since i have 2 potted ,grafted nectarines from the same variety, that are not having this problem, they were also sprayed. I will show pictures of the inground one and of the potted ones, the difference is clearly visible.
Right now i think i may have overfertilized the plant, i have put generous amount of fert on it, thought i think it got the same amount compared to my other trees, which arent having any problems now. Anyway , i will water it heavily so as to wash off the excess fertilizer. I would be happy for the problem to be the fertiliser and not something more serious, this plant means alot to me.....
Here are pics of the problematic nectarine.
Does this look like a overfertilization problem ?

Here are the potted ones, leaves are visually wider and they look exactly like they should, they also got from the fertiliser, but of course alot less as they are potted.

Temperate Fruit Discussion / Almond having a blast
« on: April 21, 2023, 07:58:51 AM »
First year of a heavy flowering for my almond. The tree had 3/4 of its canopy top worked 2 years ago, you can barely notice it now, the canopy has grown a 100 percent to its original size in 2 years.
I have 3 varieties on the tree, the goal of the partial top working was to add 2 different varieties ,so that the 3 of them cross pollinate for a better fruit set. Alot of early flowered flowers have their ovaries killed by the last freeze, but i still have alot of the flowers that are flowering now ,in a way more decent weather. Hope for a good harvest for the first time.

My vines are big enouth and every new branch that forms, adds a layer on top of the old ones, shading them which i dont think is optimal in any way. I want to consistently prune or even pinch off any new vegetative  growth that the plants want to make, hopefully cantaing the size this way and also i hope to trigger flowerring of the mature vines, along with fertilization? I recon the plants have enough mass to sustain themselves, given if i remove the new growth at all times.
Should i do this?

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 !
