One question that I get asked a lot from our shop customers is …
Can I use leftover seeds from last year?
So the answer is Yes, you can use leftover seeds to plant this year as long as they are still viable. The viability of seeds decreases over time, so it’s important to check their viability before planting. There are a few ways you can do this:
- The “float test”: Place the seeds in a cup of water. If they sink, they are still viable. If they float, they may not be viable.
- The “fold test”: Take a small sample of seeds and fold them in a damp paper towel. Place the towel in a plastic bag and leave it in a warm place for a few days. If most of the seeds have sprouted, they are still viable.
- The “germination test”: Plant a small number of seeds in soil or a seed starting mix and keep them moist. If most of the seeds germinate, the rest of the seeds are likely still viable.
If the seeds pass one of these tests, you can plant them as you would any other seeds. It’s a good idea to plant a few extra seeds to compensate for any that may not germinate.
