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.
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.
