UV light does not penetrate surfaces, so it could only kill what is on the
surface and only what receives the required UV dosage. Any bacterial in
shadows created by limbs, leaves, branches, or flower parts would remain

Light radiation falls off at an inverse square, and I'm assuming and

the trees out of leaf, I'm guessing the shadows would be covered. Supposing
