Hello everyone,
I just watched a video mentioning some bad unclean cuts on branches can die and rot back inside the trunk and eventually kill the tree.
My tree has something similar, I was gifted this carmona and it had a tip of a thick removed branch on this spot in the picture, so i removed the tip and realized it's black inside, anyway can someone check this and tell me if my tree is gonna die or be fine, please? Should I seal this with something or just let it be

For wood to rotten, it takes water. If not enough water, it cannot rot.

If I am not misstaken here, you are in Iran? Not totally sure about every aspect of iranian climate. But in my mind I see quite dry climate where rain is seldom and sparesly.

Look at natural old trees around you. Do dead parts rot or do they get White, hard almost mumified?

Healthy trees form a barrier between dead/rotting parts of the tree, and living parts. So normally cuts are not a big issue. I do however recommend to do what you can to get the bark to grow over the cut areas, especially if you make new larger cuts.

For now, main focus is on keeping your tree happy and growing well. It should not be hampered by this.

Tropfrog: yes I'm in Tehran Iran, its 20% humidity atm and we get some rain and snow all year round but not in summer.
Do you mean over watering cuzes that part to rot? The trees at the streets are fine here they make hard wood at the cutting area.

Leatherback: thanks,as far as I can tell the tree is doing quite well, makes flowers and healthy leaf and is very vigorous and makes new shoots.so I will keep any shoots appear near the spot

Thanks again, this one was my very first bonsai and is a gift from my gf and I guess I'm overreacting
I hope it does fine and it seems there is nothing I can do otherwise

No, over watering Will not cause the wood to rot. Not if properly done. But rain water running down the trunk and gets trapped in dead wood cause rotting.

Teheran gets 70mm rain per year. That Will not cause rotting unless plastic is used. Where I am we have annual awerage 772mm. Most dead wood rot in our forests.

How do you live in such a dry climate? So far this year we have had 1356 mm, and it is raining right now.

This is close to double historical average, but even the average is a lot.

I think the type of rain you get is important..

We have 185 days per year that it rains. Yet we only get some 890 mm of precipitation.

There was an article back in the seventies relating pH of rain to trees dying in the Appalachian mountains. I think it was one particular species of pine and dying was because of acid rain binding something to the tree roots, maybe aluminum ions. It's been a long time and the article was heavy on chemistry. I don't remember much about it.

Yes, ph of the water Will have impact on the rotting process. That is why peat is building up in bogs. In low ph much more is left behind in the rotting process. Strong carbon molecules Will last forever. The oldest well preserved human remains is found in a bog not far from me. The bocksten man from the 14th century. However the ph in the bog did not prevent him from dying. Just from rotting.

Back to ts....70 mm of rain reach year Will not cause rotting, no matter ph in the rain. However, low ph rain can be a reason of death to the tree.

Thanks for the effort. The rain and ph won't be a problem since i keep this fukien tea indoor and I put ot for direct sunlight in balcony like 2 hours a day, it only starts to rain at beginning of the autumn which I probably stop placing it outdoors since it will be cold and windy. Thanks everyone in total
