We have noticed two of our Christmas palms' fronds have a shredding problem...even the new growth. Have never had that problem before. These palms are 2-3 yrs old.
This is typically caused by underwatering. The plants may be rootbound and not getting enough water. You will need to check them and then either re-pot them or increase their watering. This article may help:

I recently planted a triple Christmas Palm in a large pot on my patio in central Florida. The fronds are lighter in color than my other palms and plants in the yard. It looks like it needs some fertilizer. How soon can I fertilize it? Are there any other concerns I should have?
Your palm could be suffering from Lethal Yellowing.

Removing berry branch from Christmas palm before berries have matured or fallen, will it kill the tree? I was told it would kill the tree. Please verify.
It is fine to remove the fruiting branch before the berries mature, and this will not kill the tree.
Our Christmas palm is three years old but has never produced red berries. What should we do to encourage this growth? Is it safe to remove the fronds when they are ready to fall?
Christmas palms usually produce the red fruit when they are 5 years old, so yours is siply too young. You can remove any fronds that have turned brown, but green ones should be left on the tree.
Is is OK to remove the outgrowths with tiny green berries from the trunk of the tree or should they be left on?
You can remove them before ripening to avoid any messes they can create.
