I'm curious about the viability of vegetable and tomato seeds that are several years old (around 5+ years). I just moved to a new place where I have the opportunity to set up large raised beds for gardening. I've got a stockpile of seeds, mostly hybrids with a few heirlooms, from the last few years. While I do want to try some 'seed dumping' experiments, I primarily want to ensure my plants grow healthy and strong. My main concern is whether these older seeds will still produce vigorous plants despite being older. Should I stick with fresh seeds for the best results?

You can definitely use those older seeds! Just keep in mind that germination rates might be lower than usual. The good news is that the seeds that do sprout can still grow into healthy plants. So if you're willing to plant a few extra, you should be fine!
I say go for it! Just plant a few extra seeds since the older ones might not sprout as well—especially the onion seeds. I had success with 7-year-old onion seeds and older tomato seeds, so don't hesitate to use what you've got!
Honestly, a seed that’s been stored well (cool and dry) can last for ages. I've successfully grown tomatoes from seeds collected 10 years ago! Just keep in mind that different species have different longevity, like lettuce not being as durable as tomatoes.
I’m okay with managing lower germ rates. It's reassuring to hear the vigor shouldn't be too affected!
