Starting Petroselinum crispum 'Forest Green': indoors or direct sow?
🏠 Start indoors 3 weeks before your last spring frost, then move the seedlings outside.
Start seeds indoors three weeks before the last frost date and transplant seedlings outdoors once they have developed a few sets of true leaves and soil temperatures are cool but not freezing.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.0 for best results. Since parsley is a cool-season crop, sow seeds indoors or directly outdoors two to four weeks before your last expected frost date. Press the tiny seeds gently into the soil surface without covering them deeply, as they need light to germinate. Expect sprouts in fourteen to twenty-one days.
Space seedlings six to eight inches apart once they are large enough to handle. This herb does not require staking or trellising but benefits from consistent moisture, aiming for about one inch of water weekly. Apply a light layer of mulch around the base to retain soil moisture and suppress weeds. Feed lightly with a balanced fertilizer if growth seems sluggish.
Watch for aphids, carrot weevils, and parsleyworms; hand-pick caterpillars or use insecticidal soap if infestations occur. Prevent leaf blight and crown rot by ensuring good air circulation and avoiding overhead watering. Harvest leaves when plants reach maturity, typically seventy to eighty-five days after sowing. Snip outer stems first to encourage continued production throughout the season.
