Meyers are famous for shedding any fruit that they can not support. If the trees are getti g adequate water and nutrients they will still shed a few fruit. In container trees be cautious of this & be sure to keep water & nutrients at the correct level. Unless Meyers were shedding all or most of the fruit it would not be a worry. Also remember tbat all fruits, much as the rest of nature, are not perfect and will at times be aborted.
