I'm planning on using a lot of old seeds this year. They're packed for 2013 and are carrots, corn, cucumber, melons, zucchini, pumpkins, and tomatoes.
Is there a risk of my plants sprouting and growing. But then withering and dying or will they just not sprout? I would like to know so I can buy more if I get no sprouts.
Are any of those seeds guaranteed to not sprout? I'm thinking the corn is not going to.
And (off topic) should I buy potatoes and Jerusalem artichokes at the grocery store or are there benefits to buying them from a seed catalog?
