Years ago I was walking under the one in my front yard that has coconuts the size of basketballs and one fell rite behind me I felt the breeze from it. That's a 28 footer almost fully extended I use a 32 on the taller ones. If you want them to look nice all the time every 3-4 months I think that one is at 6 months, I do a better job on the shorter ones I use a chainsaw, I will post a pic tomorrow. Only birds and ants live in the ones down here, what the heck are roaches doing that high up..lol Haha, I have a couple hundred of them that would be a million dollars to ship. Its a pain in the ass to keep them looking nice I have 8 palms and some are even taller than that one. You use a super sharp machete to cut them open
