Likely causes
Salt spray damage
Most likelyHow to tell: The tips of the needles turn brown, especially on the side facing the ocean. This happens after heavy wind storms.
What to do: Rinse the foliage with fresh water after a major storm to wash away salt deposits. Provide extra water to the root zone to help the tree flush out salts.
Severe drought
PossibleHow to tell: The tips dry out and become brittle during long dry spells. The tree may look generally thirsty.
What to do: Water the tree deeply once every 7 to 14 days during dry periods. Ensure the water reaches at least 12 inches deep into the soil.
