I planted areca palms across the front of my lot about 20 years ago. They grew to 25 feet or so by the time I actually moved here a couple years ago. I just cut down all the tallest trunks, hoping they'll send up more new shoots because I need more of a hedge at the road. With my arecas, the bases are now about 3'in diameter and the tops spread 10 or 15' across - depending on how straight the trunks are. With age, the outer trunks tend to angle out from the base a lot. If you want them fuller looking, then cut the taller trucks earlier than I did. (Don't wait 20 years.)
