O think its a latent desire in all of us, exacerbated by pruning them with the incorporated encounters with cockroaches, rat faeces and husk dust...Now I want to blow up a palm tree. Thanks a lot. I live in southwestern PA. We don't have any palm trees. I will have to travel quite far to fulfill this new desire.
Shit sticks.....killed 2 yesterday....was a pleasure.....I hardly do any. I jack up proce on cleaning them so people would run. If I get them at least I make money. I abhor the nasty useless things. They just suck the planet like lawns.....They're not worth it. Shouldn't even be called trees. Palm grass.
California fan palm is a filifera, a Mexican fan palm is a robusta,It would be very helpful to know where you are. My quick guess is Washingtonia robusta, (California Fan Palm) but I'm fully prepared to be completely wrong. Depending upon where you are, you may want to fertilize with a slow release component 8-2-12+4 with micronutrient formulation. The problem is finding a formulation consisting entirely of time-released components. Any other palm fertilizer is a waste of time and money.
Other than that, they are self cleaning palms. The petticoats forming from dead fronds are excellent habitat for mosquito eating bats. Periodically the leaf bases will slough off on their own. Trying to remove them prematurely can leave wounds in the trunk, which can then be colonized by Thielaviopsis fungi.
Don't prune off any fronds with any green at all in them. They're considered self-cleaning palms and really don't require pruning.
