dead needles on dwarf mugo pine

Question

I found many dead needles in the bottom of the topiary dwarf mugo pine when first grooming this summer. (I mean handfuls of these long needles!) I just planted it this year. Am I doing something wrong? The rest of the plant looks good and healthy right now.
