Bud rot is caused by a fungus which causes the heart fronds of a palm tree to wilt and die. Tree death can occur soon afterward.California and Mexican fan palm trees and Mediterranean (European bush fan Palms) are the most vulnerable, but in the Pacific NW with our colder and wetter winters the Moroccan blue bush fan palm, Pindo Palm and Chilean Wine Palm trees also may develop the fungus. Even though the damage is done in the winter months, spring & summer are the worst seasons for bud rot to show up on the trees. Chemicals can be effective in the early stages of this and other diseases. Consult a specialist and follow directions carefully. This fungus often occurs after a harder winter, a brief near-record low cold spell, or during prolonged colder than normal periods in the winter. This causes damage to the tender fronds which are then susceptible to the fungus. In all cases where fungal infection is a threat, it is important to prevent the careless spread of spores. Make sure gardening tools are kept clean at all times. Sterilize between finishing work on one tree and starting work on the next.
