How to Save Flower Seeds from Your August Blooms
August is the perfect month to start saving seeds from your favorite summer flowers. By collecting seeds now, you can fill your garden (and share with friends) next year for free—while keeping varieties you love and selecting the strongest, healthiest plants from your own patch. Here’s a simple, step-by-step guide to making your own seed bank from August’s blooms.
Why Save Flower Seeds in August?
- End-of-season bounty: Many annuals and perennials have finished flowering and are producing mature seeds.
- Cost savings: No need to buy all new seed packets next year.
- Garden adaptation: Seeds from your yard are already “trained” for your conditions—often stronger than store-bought.
Best Flowers for Seed Saving in August
- Annuals: Marigold, cosmos, zinnia, calendula, poppy, nasturtium, cornflower, sunflower, sweet pea.
- Biennials/Perennials: Foxglove, hollyhock, aquilegia, rudbeckia, honesty.
Step-by-Step: Saving Flower Seeds
1. Wait for Full Maturity:
Let seed pods or heads dry on the plant until brown and papery. Immature (green) seeds seldom germinate.
2. Pick a Dry Day:
Moisture causes mold during storage—choose a sunny, dry afternoon for collecting.
3. Collect Carefully:
- Hold a paper bag or envelope under the seed head.
- Snip off whole pods or shake free-flowing seeds directly into your container.
- For tiny seeds, cut the whole seed head and let it finish drying indoors.
4. Dry Thoroughly:
Spread seeds in a single layer on kitchen paper or a tray in an airy, shaded room for about a week. Turn them once for even drying.
5. Clean and Sort:
Remove chaff, fluff, or debris so only sound, plump seeds remain.
6. Store for Success:
