NO!  Well maintained fruit trees pose only a minimal fire threat.  Prune all trees regularly by removing dead limbs and thinning the canopy.  Tall, Mature trees should be limbed up 10 feet from the ground.  It is best not to have any other combustible vegetation beneath trees, but if you do, limb the trees to 10' above the top of surrounding vegetation. 

 

Conifer trees or other more combustible varieties should be limbed at LEAST 10' from the ground (the higher the better) , should not have any vegetation below them, and should be spaced at least 10' apart.  Remove any limbs that overhang your roof, and cut back limbs 10' from your chimney.
