I have a Kentia Palm for probably 1.5 years now. Over the last 6 months it's deteriorated a bit, showing brown and dead leaves.
It's in a living room away from direct light (but still get indirect light). It's the end of winter now and has been cold (could be factor). Furthermore, the house is generally on the cold side (possibly another factor). It's in a good pot with drainage at the bottom (concealed).
I've recently repotted it as I was worried the root ball wasn't really propogating (which was true) so it's in fresh soil now.
I've been keeping it on the dry side, but recently gave it a good shower which seems to have helped, although hard to tell.
I'm wondering is humidity possible a problem too here? It might need more regular misting, or a humidifier.
