Growing parsley from seed: You can purchase established plants from a local nursery, but you’ll get more plants for less money if you start with parsley seeds.

We usually wait until the plants are about five inches tall, and then those plants are transplanted into containers and grown outside or on a sunny window sill. The advantage of growing parsley in containers is that you can move the plant to a new location to optimize its growing requirements.
Choosing a pot and growing requirements: For growing parsley choose a rather large pot, 10 to 12 inches deep and wide. The container must have drainage holes. You can grow as many as 4 plants in this size container. Parsley grows best in moist, well-drained potting soil. You can also add aged compost to the container to supplement nutrients. Parsley in containers should reach 12 to 18 inches in height. It grows best between 72–86 °F and requires full sun. Remember that parsley in containers requires constant watering throughout the season. One container is plenty for an average family.
Harvesting Parsley in Containers: Harvest parsley leaves when needed in your favorite recipes. You can start harvesting parsley about three months after planting. Wait until the stems and leaves have matured. Cut the entire stem carefully from the base as parsley stems are also edible and tasty. Work from the outside of the plant and let the inner portion continue to grow. Think of parsley as a continual harvest crop but do not over pick your parsley, give it some time to grow back. Pick the dead and faded leaves from time to time to keep your plant in shape and looking good. If flower stalks develop remove them to promote green foliage growth.
