Mexican Fan Palm Removal

Q. We have decided to have our Mexican fan palms removed. Do we need to have all the roots removed or just cut the palms down to the ground, especially the one next to the pool?

One of the "fan palms", most likely favoring California fan palm (because it is "fat" at the base) (W. filifera). Palm trees in general, Washingtonia types in particular, interbreed easily and so the genus can easily be genetically mingled. 

A. If your palm trees do not sucker from the base (date palm, Mediterranean fan palm do produce suckers from the base) then as soon as the top is cut off, the palm will die. Both Mexican and California fan palms have one central bud at the top which is the only place where new growth can occur. Once cut and they die, they will slowly decay if left behind.

            The problem you will have when you leave any kind of stump is the palm trees very slow decay rate. Palm debris decay or rot very slowly. Coir is taken from coconut palms and is used in soil mixes to build soil structure because it resists decay. It is slow to decay and is the main reason I discourage its use in compost piles or use in woodchip mulch. It makes a great semi-permanent component in soil mixes. In both cases you want fertilizer or compost added to circumvent its slow decay. When plants decay, they add to the organic content of the soil and help make it darker.

Remove as much of your palm trunk as possible. The palm roots won’t regrow, but any debris left behind from the trunk will decay very slowly. If you decide to use it in your new soil mix (it is a great addition to soils to improve soil structure), chop it as small as possible and make sure that fertilizer or compost is added to the soil to compensate for the slow breakdown of palm debris.

What is covered?
Each type of fruit tree is different when grown in our desert climate. Topics will be discussed for each type of fruit tree and how our climate affects each type of tree.

Selection. Which fruit trees are best for this climate? What tree characteristics should I look for at the nursery?

Planting: Which trees are most wind resistant? How big is the hole? Compost vs soil amendment. How deep should I plant it? Is staking really necessary? How to protect the tree from rabbits?

Growing: How do I know if the tree needs fertilizer? How much fertilizer should I give it? When to fertilize? What fertilizer should I use? Will it grow in rock mulch? Does my tree need iron?

Water: How often to water in the beginning? How much water does my fruit tree need?
Insects: How to control insects that damage the tree? Which insects are the most damaging?
Disease: Which diseases are possible and how to prevent them.
