Pindo Palm: Dry newly growing fronds in the crown
I have a Pindo Palm that has survived 5 Dallas Winters. This year we had a pretty mild winter and therefore, the Pindo Palm tree had a good early start and started throwing out new fronds until recently I noticed that the crown where the new fronds come out is getting dry. One of the new frond is also dry. The old mature fronds are still good and green. I am puzzled, what could cause this. We are having weather in the 90s+. Could it be drought? But aren't Pindo Palm drought tolerant? I have, however, started giving more water to the plant. I can't see it die as it's my favorite plant.
Any advice/recommendation is appreciated.
