Strange color in bouganville cut.....

[Fidur]

So I have a couple of mini thai bouganvilles I have been caring for the last 6 months. In the nursery they came as a single seedling, and I made a separation and repoting.



So, today I decided to get rid of the central branch in the left one (I didn´t like the fork shape)





and there I found this strange color in the trunk I had never seen before



I have protected the wound with paste, but I wonder....Should I be worried ?....they are very healthy (or that is what I thought)
What do you think?
PD: I made a similar cut in the rigth one a week ago and it wasn´t like this....

I am thinking, I added some ‎iron chelate about 5 months ago .....

I used to have large bougainvillea in my landscape. That red color is not uncommon. I don't know why it is red, but just know that I saw it frequently and it didn't seem to have any negative impact on the plants.

It's just the color of the sap and nothing is wrong.

Looks like heart wood to me. When I prune them the sap is always clear. At any rate, it doesn't seem to be a problem.

I had seen the color red before
Almost looks like a water melon..

Just to say, after some chopping operations on this species under different circunstances, I've learnt that color is just the result of adding iron chelatos to the soil (the sap dye even the wood of the trunk). So mistery solved

Nice job of researching. Thanks for passing this along friend.
