Q.Healthy Palm Fronds Falling.
I have had my Queen palms for about a year and a half. I woke up and one of the lower fronds on one of my queens has snapped even though it is green and healthy. The palm looks healthy and has one new frond growing up from the top but i was wondering what cause it to break when their were no storms or anything? About a month ago another palm frond did the same thing. I feel like everytime it gets more than three fronds, the bottom one breaks and sags.

Unfortunately, your photo did not come through. I am unable to see the damage. It could be that animals are pulling them off, or that it is diseased.
