You can cut and dry the leaves remaining at the end of the season or leave the plants in the ground and try to get more use from the plants the following spring. Although parsley is biennial, most people find the leaves too bitter the second year and the flower stalks will grow surprisingly fast. However, they may hold you over until your new crop is mature enough to harvest.
Starting parsley from seed is slow. It can take several weeks for the seeds to germinate. Pre-chilling the seed in the refrigerator and then soaking the seed overnight in warm water, before planting, helps speed the process slightly and gives better germination results.
Seed can be started indoors about 6 weeks before the last frost date or sown outdoors, once the ground can be worked. Plant in a rich, loamy soil with a pH between 6.0 and 7.0. Parsley can tolerate wet soils, once established, but to thrive it needs good drainage.
Sow rows about 10-12" apart, barely covering the seed. Thin plants to every 6", once they are about 1-3" tall.
Parsley can be grown fairly well in pots, however parsley has a tap root that can get fairly long and a mature plant can easily reach 2-3' in height and 1-2' in width, so a large pot is needed.
Parsley is sometimes recommended as an edging plant or an accent foliage plant. While parsley is very attractive, be aware that it is also popular with some small animals.
