Early sowings can be made 2-3 weeks before spring’s last frost date. The tiny seeds should be surface-sown and not covered, or covered only minimally, and kept uniformly moist until seedlings are strong. May be sown throughout spring and summer at 2-3 week intervals, until about a month before first frost in autumn. Deep mellow, well-worked soil suits long types: half-longs and round types are better bets in heavier soils.
Ensure a distance of 0.39 inches (1.0 cm) between seeds when sowing - look to sow at a depth of approximately 0.23 inches (0.6 cm). Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.By our calculations, you should look at sowing Parisienne about 21 days before your last frost date.
