Care Parsley grows quickly and is best during cool periods. The plant is shallow-rooted and requires regular fertilization and watering for best results. Harvesting Clip or break off individual leaves when they are full sized. Wash leaves and store them in a plastic bag in a refrigerator for up to 2 weeks. Parsley can be dried for later use or leaves can be frozen easily.
Freeze leaflets on a cookie sheet so they can be separated for later use.
