My Yaupon Holly is pale and not many berries. There is also many areas that have moss starting to grow. Do I a need a pesticide? I live in Florida. I have had it about 3-4 years. was growing great.

I would suggest taking a soil sample to your local extension. They can tell you what is going on, but I'm going to guess that the soil is somewhat salty. This can cause nutrient lockout. Usually these don't need a large amount of fertilizer, so I don't really think it needs food. This leaves me to believe that the soil isn't the proper environment for this shrub.
