Mexican Fan Palm Washingtonia robusta

Description

Mexican Fan Palm is unsurprisingly a palm tree native to Mexico that has naturalized in Florida, California, Hawaii and Texas. Its columnar trunk can reach up to 100 feet tall with a round crown of fan-shaped fronds that can grow 3-5 feet long. Rather than dropping off, dead leaves fold down against the trunk giving it a dense skirt. These should be removed to prevent a fire hazard. As the tree grows taller it may become self-pruning. At least 50% of the fronds should be left on the tree for adequate photosynthesis to occur. Frond damage can occur at 20 degrees F.

Mexican Fan Palm is easy to grow in well-drained soil in full sun to partial sun. It is drought, wind and salt tolerant. It is often used in coastal plantings but because of its height, it looks best in lawns with tall buildings or houses. It is also used in parking lots or as a street tree.

Problems: Potassium deficiency can cause leaflet tip necrosis, leaf discoloration, and premature death of the oldest leaves. Few insect problems but watch for spider mites and scale. Fungus diseases can cause trunk rot.
