My pygmy date palm has been in my living room for 2 years. I DO notice it has a nasty habit of collecting dust and being difficult to keep clean - the best way for me was to give it a day outside once in a while and hit it with the hose on a light spray. It has grown VERY slowly but leaves turning brown has been a continuing problem. I have had a wonderful experience with my spindle palm as an indoor palm - even in relatively low light areas. It continues to grow indoors, although very slowly - and is beautiful, majestic-looking, and the leaves stay nicely green for a long time. I find they aren't easy to find, but if you find one, a spindle palm has worked out great for me. btw good call on the majesty palm. They don't really like being indoors - although there is no way one would grow very fast indoors. Good part about majesty palms is they are disposably-priced :)

Looks like too much heat and not enough water. If it had been grown in less then full sun,then its also adapting to that with old fronds burning. Water more,and see if the new flush of fronds is greener. If so-home free! Also,If your in a Sunset desert zone or a hot inland soucal valley-it will always need some shade to look best.

Watering can be tricky as the negative effects of too much water can resemble too LITTLE water. Your palms are containerized right? Not sure how drip system works with smaller containerized plantings. Watering depends on a lot of factors (sun exposure and duration, soil type, heat, humidity, etc.) When you put your fingers beneath the soil to a half inch, how does it feel (wet, moist, dry)? Keep in mind that this species is native to humid tropical/subtropical, fairly moist climates (not a desert or Mediterranean species at all). Good luck!

How cold has it been where you are? I've got a 3 foot planted Pygmy Date and 4 that are 8" tall and in small nursery pots. I planted the large one this summer so this is my first attempt at trying to overwinter it in zone 8b Alabama. Luckily we've only had two light freezes so far. My method was to put a portable greenhouse over it and I'm using a small heater on cold nights. Each morning I've just been misting it with a hose for a few minutes and it's very green besides a little curling on the ends of the fronds. I also put 2 slow release fertilizer sticks in the ground in early November. Have you fertilized yours? I would also place them in direct sunlight if you can and see if that helps. I'm definently not an expert and still trying to get mine to look healthier but hopefully I can be of some help.
