Our foxtail palm, what causes the fronds not to open all the way?
The frond grows great, but has a really hard time opening up. The spear will start to open at the end and the rest just stays closed. We have a lot of foxtails on our property, but this one tree is the only one we have a problem with.

Avoid removing fronds unless you're 100% sure palm leaves are brown and dead. Palms need their old fronds to help support new growth.
Rough winter weather, heavy rain, saturated soil—all these things can play a role in a palm tree spear not opening up.
A shortage of boron in the soil is a common cause of deformed spear leaf growth. Without the right dose of boron, the spear leaf stays tightly wound up instead of spreading out.
