The california fan palm is the only palm tree native to the western united states.  All other palm trees that you see in the area have been moved to our area.  This tree is often mistaken with the Mexican fan palm.  While this tree is native to the area it is not the most promintent.  That goes to the Mexican fan palm.  They can be seen everywhere in California.  California fan palms grow to the height of 65-85 feet at maturity.  Fronds are up to 6 feet long and make up a formation of leaflets that can be up to 7 feet long.  

Current threats to this tree include the palm broing beetle.  This insect bores through the thick trunk of this tree doing damage to the living layer.  Red palm weevil may become the worst tree problem in the state of California.  This insect eats the fronds of the tree killing off palm trees completly.  Fusaruim rot is a disease of the roots.  It causes palm trees roots to die.  This will lead to the death of the tree and often uprooting is likely.

It is a relatively inexpensive palm tree and will grow very well in almost any soil condition including sandy soils like pictured to the left.  Mexican fan palms tower to almost 100 feet tall and have slender trunks usually 10-12 inches in diameter before tapering out near the base of the tree.  

 Leaf spotting and yellowing are common diseases of Mexican fan palms.  These diseases are funguses that effect the leaflets of the palm tree.  They start small and expand over time until they take over the palm tree and start killing it off frond by frond.  Red Palm weevils and palm boring beetles are also insect problems of the mexican fan palm.

Some insect problems like whiteflies, weevils and leaf hoppers can become problems with queen palm trees.  All of these insects are fatal in mass infestations.  Insects like leaf hoppers spread diseases in palm trees.  While weevils eat the living layer out of these beautiful trees.  Queen palms are very tolerant of cold weather and are said they can handle temperatures as low as 20 degrees.

This palm tree which is native to Guadelupe island was moved because of the issues keeping this tree alive on the island.  Goat heards were eating all of the new spalings so they exported the palm tree mostly to California.  Fortunately for you that own this beautiful tree there are not many diseases known.  Red palm weevil is a major problem though to all palm with the exception of few varieties.  

None of the butt rots or cankers are known in this tree.  It is still important to look out for nutrient problems in this tree as it is not native to our area and soils.  Making sure to feed this kind of tree two times a year might insure that the doctor does not have to make a house call.  Pretreatment for red palm weevil and orange palm weevil should be applicated to insure these kinds of trees do not die off.
