Should I trim off the brown tips?

Yes, you can snip them off with clean shears for aesthetic reasons. Just be careful not to cut into the healthy green tissue.

What to do: Flush the soil deeply with plain, unsoftened water to wash away excess salts. Avoid using chemical fertilizers for a few months to let the roots recover.
Inconsistent watering
Possible
How to tell: The leaves look dry and brittle at the edges during hot, windy weather. The soil feels very dry several inches down.
What to do: Water the tree deeply every 7 to 14 days during dry spells. Ensure the water reaches at least 2 feet deep to support the root system.
