If you’re an avid gardener or just starting out, you might wonder: How long do seeds last? At SimplyGro, we know that every seed holds the promise of a thriving garden, but understanding seed longevity is key to making the most of your gardening efforts.
WHAT AFFECTS SEED VIABILITY?
Seed Longevity varies depending on several factors.
1. Seed Type: Different seeds have different lifespans.
- Short Lived Seeds (up to 2 years): Onion, Parsley, Corn & Spinach.
- Moderate Lifespan Seeds (up to 4 years): Beans, Carrots, Peas & Peppers.
- Long Lasting Seeds (5+ years): Tomatoes, Cucumbers & Squash.
2. Storage Conditions: Proper storage can extend a seed’s viability. Store seeds in a cool, dry, and dark place. Ideal spots include airtight containers in the refrigerator or a cool basement.
3. Moisture & Humidity: Moisture is the enemy of seed longevity. Even a little humidity can trigger premature germination or rot. Use silica gel packets to keep stored seeds dry.
4. Seed Quality: Fresh, high-quality seeds from a reliable source (like SimplyGro!) will naturally last longer than older or improperly stored seeds.
HOW TO TEST SEED VIABILITY
Before tossing out old seeds, try this simple germination test:
1. Place 10 seeds on a damp paper towel.
2. Fold the towel over and seal it in a plastic bag.
3. Leave it in a warm spot for 7-10 days.
4. Count how many seeds have sprouted. If 7 out of 10 sprout, you have a 70% germination rate—still good enough to plant!
EXTEND THE LIFE OF YOUR SEEDS
Want to make your seeds last longer? Here are some pro tips:
- Label your seeds with the date you purchased or harvested them.
- Vacuum seal for extra-long storage.
- Freeze seeds for long-term storage, but ensure they’re completely dry before freezing.
WHEN TO REPLACE YOUR SEEDS
Even with perfect storage, seeds will eventually lose their ability to germinate. Here are some signs it’s time to refresh your collection:
- Poor germination results from your at home test.
- Seeds that look discolored, moldy, or damaged.
- The seed coat appears shriveled or brittle, a sign of aging.
