Its not on my property so it doesnt bother me. if it was on my property I would have torn it out as those fan palms are a nuisance.
It usually takes a couple years for the palms to adapt to their locations and tehn they explode with growth. If you palm isnt growing as well as it should, it probably needs more water and most importantly fertilizer. Palm spikes twice a year and plenty of H20 can work wonders.
Not humid enough for coconut palsm, they need tropical weather not mediteranean climates.
