• What to Look For: Search for phrases like "Packed for [Year]" or an expiration date on the packet.
• Why It Matters: While seeds can remain viable for 10+ years, the packaging date indicates when the seeds were at peak germination rates.

Pro Tip: Older seeds may still sprout, but their germination rates might be lower. Be prepared to plant extra seeds to compensate.

• What to Check: Examine the seeds for any cracks, chips, discoloration, or mold (white or fuzzy residue).
• How to Test: Lightly pinch the seeds—healthy seeds will feel firm and solid.

How to Test:

1. Place 10 seeds on a damp (not soaking) paper towel.
2. Fold the towel and place it inside a resealable plastic bag.
3. Keep the bag in a warm spot (65-75°F for most seeds).
4. Check daily after 7-10 days.

What to Observe: Count how many seeds sprout to determine the germination rate.

How to Test:

1. Fill a bowl or glass with room-temperature water (68-77°F or 20-25°C).
2. Gently drop the seeds into the water.
3. Wait for 15-30 minutes.

What to Observe:

• Viable seeds typically sink within this time.
• Non-viable seeds will float. Some seeds may initially float but sink after absorbing water—be patient before making a final judgment.

Pro Tip: This test works best for larger seeds; smaller seeds may not behave consistently.

Ideal Storage:

• Use breathable containers, like paper envelopes or cloth bags, to allow airflow.
• Store seeds in a cool (32-50°F), dry, and dark place, such as a fridge or dedicated storage box.
• Avoid: Locations with fluctuating temperatures, like garages, attics, or windowsills.

Pro Tip: Label your storage containers with the seed type and date for easy tracking.

• Direct Planting: If you’re uncertain about viability, plant the seeds directly in soil.
• Why It Works: Seeds can sometimes surprise you by sprouting even after years of storage.

Pro Tip: Use this method as a last resort or when you’re ready to experiment with older seeds.
