Wait for a sunny morning after the dew has dried, when your plant is in an outdoor garden or in a container on a deck or balcony. Wet bay leaves are fine when they go right into a recipe, but can become moldy if stored while damp.
Clip older bay leaves first. These leaves are typically larger, more pungent and found near the bottom of a plant's woody stem. Use a sharp scissors or shears, or your fingertips, to sever the leaves.
Use fresh bay leaves immediately after harvest for more pungency. When harvesting a large number of leaves at one time for drying and storing, collect whole stems with leaves intact.
Bundle the bay leaf stems into bouquets tied at the woody base with twine. Hang the bunches with the stem ends up in a dry, warm and well-ventilated area, such as an attic, hall closet or a corner in the kitchen.
Keep the drying bay leaf bunches away from humidity and direct sunlight. Store harvested, dried bay leaves in airtight containers.
