Seed Selection and Planting: Choosing Viable Seeds for Strong Plants

Even reputable seed houses can't guarantee every seed's vitality. Smart selection—whether saving your own or purchasing—dramatically improves germination and plant quality.

Saving Your Own Seed

Evaluate the entire plant, not just the bloom. Weak, straggly parents produce similar offspring. Select sturdy, well-shaped plants with abundant quality flowers. Professional growers tag chosen blooms on superior specimens.

Seed Size Matters

Larger, plumper seeds contain more stored nutrition (cotyledons) for the embryonic plant's critical early growth before roots function. Like weak children, undernourished seedlings struggle. Choose the largest, fullest seeds.

Purchased Seed Pitfalls

• Impurity: Similar-looking weed seeds mixed in—easy to clean large seeds, nearly impossible for small
• Viability: Immature harvest, freezing, or age kill germination power. Each species has a viability lifespan.

Germination Testing

Low germination percentages are acceptable for small seeds (sown thickly in drills—quantity compensates). For large seeds (corn, beans—planted precisely), high germination is essential. Test before committing garden space.
