EASIEST TO START OUTDOORS
Start parsley in spring when weather is settled but still cool and/or in late summer in mild winter climates. Plant in full sun or half-day sun if climate is very hot. Sow seeds 1- 2 inches apart into a well-worked fertile seed bed. Cover 1/4 inch deep. Parsley germinates unevenly over several weeks; be patient and keep seed bed evenly moist. Using synthetic row covers to hold moisture during germination is helpful; remove when seedlings are well established.
TO PLANT INDOORS
In early spring, sow seeds 1 inch apart and 1/4 inch deep in a container of seed starting mix. Keep container moist but not soggy until seedlings emerge. Provide a good light source. Feed seedlings frequently until ready to transplant when several inches tall.
Parsley needs rich moist soil and ample spacing for lush harvests. Thin early and keep well weeded and watered. Begin to harvest sparingly once plants have 8 to 10 leaves. Fertilize frequently with a high nitrogen source.
