I’m I killing my Palm Tree?

I bought my potted palm tree a month a go from Walmart. I re-potted into larger pot (?10”?). To make the top of the pot a bit nicer, I planted some other plants underneath the palm. I have been watering it often and the top soil is always wet and I thought this will help the smaller plant do well. But I realize that my palm tree leaves are turning gray like drying and in this way most of it already gone except for the inner most. I think I am over-watering it but not sure even if the re-potting it self may have done it (but obviously I do not like the plastic container of Walmart). I am using rain water from rain barrel. It is in front of the window and gets most of the light but not direct sun light. It is in the living room and not directly to the AC outlet. I have some pictures to give you idea. Thanks for helping to save this tree.

Hi, Totolamo, how is your palm tree doing now? It does sound like overwatering, but I'm no palm expert. I water mine about once a week, or when the soil starts to feel dry if I stick my finger in a couple inches deep. You do need to make sure whatever plants you put in with it have the same care requirements.

You're almost certainly overwatering if you're keeping the top of the soil always looking wet. The top of the soil dries out much quicker than the soil underneath where the roots are and a palm tree does not like its roots to be in constantly wet soil. The best way to check if the plant needs water is to stick your finger down a few inches into the soil and see how wet it feels. If it's still feeling wet a couple inches down, then you shouldn't water even if the top of the soil looks dry.

I have one also, the best thing u can do f/it is NOT to over water it, only give it water when the water feels moist to u, I got this f/ serching internet., mine is doing fine and health, will gladly post pict of it ok? I know a lot about about house plants as my Mom always had them when I was growing up, am now 62yrs.

Over watering kills more indoor plants than anything else, I would re-pot the plant into fresh new compost for houseplants, remove as much of the wet compost you can from the roots and then pot it back into the new compost, don't water the plant for several days IF the compost feels dry, but you can mist the foliage to help keep a bit of humidity onto the plant.
Once you begin to water the plant again, slowly pour water into the compost, soon as it begins to drip through the bottom of the pot, stop the watering, allow the plant to sit in the water inside the saucer for about half an hour / hour then pour the water away, this indicates the water has been soaked up and enough is taken by the plant / compost. continue to mist when you water the soil.
Once you see the plant has settled, you can remove the dead and damaged leaves, cut them off right against the stem but be careful you don't cut the stem. After a couple of months you will see a huge difference to the plants health and it will have settled down. Come winter, keep misting the plant as the heating will dry the air in the room and plants don't like this so keep the misting up, continue to test the soil to find out if the plant needs more water, in a few months you will know how often the plant needs watered.
Good luck, WeeNel.
