Growing zinnias at home? Here's what to do after they finish blooming
Gardeners can save zinnia seeds from healthy plants for next year's blooms. Letting flowers dry on the stem ensures mature and viable seeds for collection. Avoid composting spent zinnia heads to prevent unwanted seedlings in vegetable patches. Decide whether to pull plants or leave them standing for natural seeding. Proper seed storage in cool, dry paper envelopes ensures viability for future planting.
