Before you sow those treasured zucchini seeds from last season, it’s essential to ensure they are still viable. Seed viability can dramatically affect your garden’s yield. Here are some reliable methods to test your seeds:

  • Water Test: Place a few seeds in a bowl of water. Viable seeds will sink, while non-viable seeds will float. Let them sit for about 15 minutes to determine their viability.
  • Paper Towel Method: Moisten a paper towel, place a few seeds on it, and fold it over. Keep it in a warm place and check for germination within a week. If at least half sprout, your seeds are good.
  • Age Check: Consider how long you’ve stored your seeds. Generally, zucchini seeds can remain viable for 4 to 6 years if stored correctly. However, testing them will give you peace of mind.

It’s beneficial to maintain a record of your testing process. A simple table can help you track which seeds tested successfully:
