Storing and keeping seeds

Question from Monty:
If I have seeds I don’t use during a current planting season, what is the best way to keep or store seeds in hopes they’ll be good for when I’m ready to put ’em in the ground?

Answer from Pat:
Some seeds such as onion seeds don’t store well. Others such as parsley or carrots store for years. Put dry unused seeds into an air-tight, screw-top jar and enclose a desiccant. You can purchase packets of silicone desiccant and these are often reusable by heating in the oven. Or you can make your own home-made desiccant by wrapping one or two Tablespoons of dried skim milk in a Kleenex tissue and closing up with a paper clip or rubber band. Label the jar and keep it in a cool dry place out of bright light.
