Hi there, i have a tropical plant in the Netherlands indoors.
The room its in is about 24C and it had sunlight, this plant is used to 25-35C.
And i'm not joking i had it in the oven at 40C for around a weak before it came out.
The others didn't even come out and its been 3 months ago.

The leaves grow fast and then end up curling at the end and turning black. like 5MM.
It's a very unknown plant and theirs almost no information about it online.
Thumb of 2017-09-14/Farnk/3da418
Other leaves just grow odd:
Thumb of 2017-09-14/Farnk/070973

Other information:
It has a lot of horse soil mixed with pot soil and tropical soil.
it has tropical white sand, and gets only water by the leaves.
It has a estimated growth time of 3-8 Years.
It's actually a tree not a plant. growing from 3 to 25 Meters.
It's a child hood tree with delicious fruit.
The country it grows in is getting to warm for the tree to give fruit.
The people in that country just eat them instead of reproducing it.


So the problem is, why is the tip of every leafe turning black after it fully grows.
Why are some of them just growing in a odd position.

I feel like we are playing "20 Questions"...

The leaves are turning black because:

you never water it and it needs some water once in awhile?

Too much horse manure so the leaves are burning?

Its not happy as an indoor plant?

I give the soil water once a week and spray the leaves every 12 hours.
If i only water the soil the leaves wont grow.

Too much horse manure so the leaves are burning?
Could be, so i just need to replant it?
But the leaves only start burning after they get fully grown

Its not happy as an indoor plant?
it will die outside and its dying in the land it came from.

It would be handy to know what the plant is and what land it came from.

Looking at this plant (Syzygium jambos) and its relatives, it appears they need a LOT of water and very high humidity. Average rainfall is 1200 - 1600 mm per year!

I suggest you start watering your tree daily (until water runs out the bottom hole) and place it on a humidity tray (a waterproof tray full of pebbles that you can keep water in to raise the humidity). Misting every 12 hours raises the humidity while you are misting but that's it. If you could find a small humidifier to place near your plant, that would be better yet.

These trees have a reputation for not transplanting well. Transplant as a very last resort. Also, it doesn't appear they are dying anyplace except Hawaii and are considered invasive in some areas. Because you grew your plant from seed, if you ever get fruit, the quality will be uncertain and maybe not what you were hoping for. All the commercial growers are growing from cuttings from proven plants.

Hi and welcome. I agree with Daisy that the cause of the burnt tips on your leaves is very likely the horse manure in the mix. Potted plants need measured, timed release fertilizer in a pelleted form. Things you can use outside like horse soil release their nitrogen too fast for indoor potted plants.

As Daisy suggests, flush the soil with pure water for a few days, making sure the soil drains well, and the water doesn't collect at the bottom. Then use potting compost only for the medium to grow your tree in, since you must keep it in a pot forever. Other soils such as garden soil and sand will compact too much in a pot, and not allow air spaces around the roots. This will eventually lead to root rot and death of the plant.

Do you put it outside for the summer weather at least? As long as the night temperatures are above about 18C it would probably do well. I would think as it grows your biggest problem for growing this equatorial fruit tree will be to give it enough strong sunlight. Give it sun every chance you get, keep it as warm as you can and away from drafts. Water and fertilize consistently. In other words, give it a tropical equatorial climate as closely as you can. Good luck!
