How can I prevent mold from forming on an avocado seed while trying to grow it?

To prevent mold from forming on an avocado seed while trying to grow it, make sure to clean the seed thoroughly before planting it. Use a clean cloth to wipe off any residue on the seed. Additionally, ensure that the seed is not sitting in water, as excess moisture can promote mold growth. Finally, place the seed in a warm, well-ventilated area to discourage mold formation.
