Parsley (Petroselinum crispum) is native to the central Mediterranean region, including southern Italy, Greece, and Tunisia. It has been cultivated for more than 2,000 years and was used by the ancient Greeks and Romans both as a culinary herb and for medicinal purposes.
To harvest parsley, cut the outer stems at the base of the plant, leaving the inner stems to continue growing. Regularly trim back the plant to prevent it from bolting (going to seed) and to encourage new growth.
Harvest parsley as needed throughout the growing season. For the best flavor, pick the leaves in the morning after the dew has dried. Cut the stems at the base to encourage more growth, and use fresh or dry the leaves for later use.
General Prevention: To prevent pest problems, practice crop rotation, and ensure good air circulation by spacing plants adequately. Mulching can help retain moisture and reduce weed competition. Regularly inspect plants for signs of pests, and remove any affected leaves to prevent the spread of damage
