The California fan palm is a thick tree found along the west and north edges of the Colorado Desert. Originally used for making clothing, sandals and baskets, California fan palm provides shelter for birds like woodpeckers and finches. The California fan palm has a thick and robust trunk that can grow up to 65 feet high. The palm has tiny white flowers that produce oblong black fruits. The leaves are fan-shaped and gray-green in color. The California fan palm is found along groves, springs, and streams and prefers moist soils.
Prune the California fan palm of all yellow or brown fronds. This will facilitate hardy growth throughout the year.
Remove loose stems or stalks by hand. If you cannot pull them off, leave them on the tree so as not to damage the palm.
Cut all broken or diseased palm fronds by removing the entire branch. Remove all insect-infected fronds to avoid contaminating the tree.
Remove old palm flowers and fruits which can provide food for pests like insects and rodents. Removing these flowers and fruits can also free up starch that is beneficial to developing fronds and their root system.
For clumping palms, where the fronds are too close together, thin the fronds out so allow for new growth. Clumped fronds will also block essential light needed for new growth
