Store your seeds (still in their paper packets) in a well sealed container. Any container that will keep air and moisture away from the seeds will be most ideal
Keep your seed packet container in a COOL, DARK and DRY place.
NB: Use silica gel packs. Those little ‘do not eat’ white sachets you find in shoe boxes or new handbags etc. No need to tear open the sachet. A couple of these in your seed pack container will help keep moisture away.
