📷 Wikimedia CommonsStarting Evergreen Hardy White: indoors or direct sow?
🌾 Sow directly in the garden — Evergreen Hardy White is not usually started indoors.
This plant is best direct-sown rather than started indoors; simply sow seeds outdoors in prepared soil during the recommended window before the last frost.
Soil, care & harvest
Prepare loose soil with a pH between 6.0 and 7.5, as this allium thrives in slightly acidic to neutral conditions. Sow seeds directly outdoors 2 to 6 weeks before your last spring frost date, since they are a cool-season crop that tolerates light frosts. Press seeds lightly into the soil at a depth of about half an inch; germination typically occurs within 7 to 14 days.
Space plants 2 to 4 inches apart if sowing densely, or maintain 6 inches between clumps for better air circulation. Provide one inch of water weekly, though the plant tolerates some drought once established. Apply a light mulch around the base to retain moisture and suppress weeds, but avoid piling it against the stems to prevent rot.
Watch for onion thrips, aphids, and leaf miners, which can be managed with regular inspections and hand-picking or insecticidal soap. Fungal issues like downy mildew are prevented by ensuring good airflow between plants. Harvest the scallions approximately 65 days after sowing when they reach your desired size for culinary use.
