Thanks so much for sharing your vast knowledge of palms with the rest of us. This article and your other articles on palms are fastinating and informative. You should combine them all and have them published in book form!
Quick question if you don't mind. The Kentia palms that are sold in some nurseries have three trunks in the pot, as you mentioned, that are different sizes. Are these three separate palms crammed in there together or one palm that is multi-trunked. If they are separate plants, would it be worth separating them to give them their own growing space, or would the roots hate being tampered with? These Kentias are destined to be houseplants for maybe five years or so. Thanks so much!
Kentias can take quite a bit of abuse, so if want to separate them, you can, with little risk of killing them off... unlike doing the same with Majesty or King palms planted similarly. However they are sold like this for a reason- palms look nice in clusters.
