Crown rot?

[Borosbobo]

Hey!

I would like to ask you guys to help me identify the problem with my palm. 
i bought a Phoenix Canaresis like 3 weeks ago.
Im not really sure how this part is called in english but the crown part below the leaves look like they are rotting. 
Maybe some kind of insect attacked it?

The leaves are healthy they do not have any problem

Can you guys help me identify the problem and tell me how to treat it?

The holes do look like some sort of insect . A couple of my Phoenix Roebelini shed their leaf bases a couple of years ago due to rot. It didn’t hurt the palm at all. Harry

@Borosbobo the holes might have been some kind of beetle, but it looks like that was many years ago.  If there are fresh holes in the trunk it might be a beetle infestation.  If so, a systemic insecticide like Imadicloprid or Dinotefuran is a good choice.

The fibers up near the top are just the old leaf bases (sometimes called "boots") of the palm fronds rotting off.  That's normal on most palms.  If it's soft and squishy that's normal too.  If you poke around in there you should find the hard "trunk" beneath the fibers.  Eventually it'll turn out smooth and hard like the lower trunk in your photos.  If you want to, you can take a sharp pair of garden shears and snip off the fibers.  Just be careful to not cut into the hard trunk shell.

So if I understand right when the boots rot away and they fall down then the trunk will still have a nice “staircase” formed trunk like under my leaf bases? Because if thats the case then it’s fine I thought that they specifically cut the leaf bases to look like this in the nursery

 

thank you all for answering!

@Borosbobo yes they will eventually rot and fall off, leaving a mostly smooth trunk.  A lot of times people (and nurseries) will cut them off at an angle to make them look good.  Yours probably was cut, and looks like they did a good job. Once the boot is totally dead and dessicated, it should be relatively easy to trim with a reciprocating saw or hand saw.  Just don't cut into the actual trunk, only the leaf base.  Cutting them too early (when they are still live or partially green) opens up a fresh wound, which is a good way to get fungal rot infections.

Perfect thank you! I will keep that in mind
