- Soil preparation: Parsley grows best in rich, moist, well-drained soil in full sun to partial shade.
- Planting: Sow seeds outdoors when the soil temperature averages 50°F. You'll need some patience because parsley seed germinates extremely slowly, often requiring 6 weeks before the seedlings poke up through the soil. (You can speed germination by soaking the seeds in water overnight before planting.)
- Spacing: Once the seedlings pop up, thin them to 8 to 10 inches apart.
You can begin harvesting parsley as soon as the plants are growing vigorously. Snip individual outer stems from the plants; they'll continue to produce new growth all season long. Parsley dries and freezes well. If you dry it, crush it by hand after it's completely dry and store it in an airtight container.
In ancient Greece, parsley was used in funeral ceremonies and to make wreaths for graves. Parsley was also placed in wreaths given to winning athletes because the Greeks believed that the god Hercules had chosen parsley for his garlands.
