Palm tree cracking at roots

[JD11]

What can this be? How do I care for it?

Nothing to worry about... Just aireal roots forming. Bury the trunk a little deeper if you want with some additional soil - but tree will also be fine if you just leave it alone.

like @aztropic said they are advantageous roots. its a good sign of growth and very common for well grown palms. in fact, if you mound up mulch it will split even more which i do to get the trunks of my palms fatter and fatter.

Cranky old pedant here, ...it is advantageous to have these roots develop, but they are adventitious roots.

The rough equivalent of a healthy palm, er, ahem, "getting hair on its chest." If you pardon the expression. More delicately, @JD11 it looks like your palm is hitting maturity or will soon, and, if it hasn't already, might start flowering and seeding.

What kind of palm is it?

More specifically they are “root initials”

Well this answers my question as well, my Copernicia is doing the same, I guess I won’t worry then. It’s a little hard to see, but it looks the same as the OP’s palm.

Many of my fasted growing Archontophoenix exhibit this. It’s a good sign.  The adventitious roots usually make it into the soil.

Thanks Tin, It’s a tmobile tower on my lower pad

Yeah, adventitious roots are weird.  There's a Sylvestris just down the road that has them growing out of the trunk a solid 2-3 feet up from ground level!
