How do I store tulip bulbs and prevent rot before planting?

Tulip bulbs are costly so handle them carefully before planting. Keep them in a cool, dry, well ventilated place out of direct sun and away from damp, because warmth and moisture invite rot and fungal problems. Do not pile them in closed plastic where they cannot breathe, use open trays or breathable nets so air moves around them, and inspect for any soft, mouldy or damaged bulbs and remove those so they do not spoil the rest. The bulbs also need their cold treatment, so if they were supplied pre cooled keep them appropriately cool until planting and follow the supplier's storage advice. Plant them into genuinely cool conditions at the right time. For the exact storage temperature and whether your bulbs need further chilling, follow the bulb supplier's instructions and confirm with your horticulture office, since improper storage is a common way these expensive bulbs are lost.
