Why is my house palm's fronds turning brown and seem to be thinning out? Any ideas for me? I want so much to have it flourish because it is one given to me when my son died. I just never know if I'm over, or under, watering. I'm getting desperate. Thanks so much if you can help me, one more thing, the fronds seem to turn lighter green at times and sometimes have a very light yellowing tinge although I don't think the soil is very wet. That's what confuses me.
