It depends on the kind of weed killer. Some have to be applied to the growing weed, others are put down as a germination preventative and have to be placed before the seed germinates. As with any pesticide, ALWAYS read and understand the label.

Pre-emergent weed killer places a thin barrier on the ground that kills the roots of little seedlings that try to sprout, effectively stopping weeds before they can grow into a plant. This has no effect on existing bulbs (which are already beneath the layer of protection), although it should stop any new bulbs from sprouting from seeds that the plant may have spread last year.
