If you leave these dried seed heads on the plant through late autumn, they will mature. Eventually, the seeds—flat, arrowhead-shaped grains attached to the base of the petals—will drop to the soil. In warmer climates, they may sprout almost immediately; in colder zones, they will lie dormant beneath the snow and mulch, waiting for the warmth of spring.
A thick layer of wood chips or mulch can prevent seeds from reaching the soil or block the sunlight they need to germinate. will zinnias reseed themselves

Facebook +3 Reseeding by Climate Zone Your geographic location is the biggest factor in whether zinnias will return naturally: Warm Climates (Zones 7–10): In these regions, zinnias reseed very reliably. Gardeners in zones 8 and 9 often find they only need to intentionally plant every few years because the self-sown "volunteers" are so prolific.
