proper tulip bulb storage until fall
This is more difficult than you might expect. Store them in a cool, dry place in a bag with lots of air circulation, and check them often for any molding or rotting. Unfortunately, the gas emitted by certain vegetables affects the bulbs, so the refrigerator is not a good idea (unless you have an extra refrigerator). And basements and garages are often too warm. Which is why we usually store tulip bulbs in the ground.
