|This is California fan palm with cold damage from|
temperatures in the low 20's or high teens F
|Not totally sure on this one but it was probably |
light cold damage on this date palm during the
winter in low 20's
|This is Queen palm, not a good palm for the hot desert|
and probably lack of soil preparation or watering too often
|Center fronds, youngest, demonstrating yellow growth|
which could be due to watering issues, soil issues
or possibly disease
Cold damage on palms usually results in the older fronds turning a bronze color first and then browning later as they die. General rule of thumb is if more than half of the frond has turned brown, remove it. The new fronds at the center of the palm should be healthy and green when they emerge in mid-spring.
If your soil is heavy and holds water a long time then plant on a mound 2 to 3 feet high and 6 to 8 feet across so the water drains away from the roots.
