From the Outside-In
Dill grows from the inside of each stem, in a layered, "stacking" pattern - the newest stems grow from the inside of the second-newest stem on the plant.
Prune plants from the outside-in, picking the oldest stems first. Leave at least two stems on the plant at a time to allow it to photosynthesize and produce new growth.
Flowers and Seeds
If growing dill for the sole purpose of seeds, plant in full sun. Dill will "bolt", or grow flowers, when the weather gets hot, and a sunny location will help that along. Once flowers bloom, you'll notice the tips turn from fluffy yellow flowers to green balls. Each one of these balls are two seeds. Wait for the plant to begin to turn yellow and die back, but be sure not to wait too long after; otherwise, they'll drop on the ground around the plant and reseed in the form of new plants in the spring (not the worst thing in the world!).
To harvest the seeds, hold the stem in one hand and carefully cut with the other (too much jostling will cause seeds to drop). Place the seed head in a brown paper bag, roll it closed, and let it dry completely - should take 1-2 weeks. Once dry, simply shake to remove the seeds from the head. Return the empty seed head to the garden or compost pile.
