These premium giant scallion seeds develop tall, sturdy plants far larger than ordinary bunching onions. The thick white stem section delivers a mild, sharp‑sweet onion flavour, less pungent than common bulb onions, making it extremely versatile for Asian stir‑fries, grilled dishes, soups and raw garnishes. This landrace variety shows excellent winter hardiness; plants can stay standing through light frost and continue development when temperatures rise again. Deep, loose soil is key to reaching those impressive giant stalk dimensions, as compact ground restricts underground stem elongation. It fits well in dedicated vegetable rows or deep raised growing beds. Keep weeds kept under control throughout the lengthy growth cycle, and watch for thrips and leaf‑miner insect activity. Consistent moisture supports steady stalk expansion, while water shortages will result in thin, tough‑textured scallions.
Planting Instructions Soil Preparation Select a location receiving full, direct sunlight. Deep‑till garden soil thoroughly, mix in plenty of well‑rotted organic compost. Loose, deep loam is critical for encouraging long white stalk growth. Break up compacted clods; heavy clay soil needs generous organic amendments to loosen texture.
Seed Pre‑treatment Screen out lightweight and damaged seed particles. Soak seeds in cool clean water for roughly 4‑5 hours, then spread out to air‑dry on paper before sowing. No cold stratification steps are necessary for this heritage scallion.
Sowing Method Main sowing window falls in late summer for autumn and over‑winter production. Scatter seeds thinly across seed rows and cover lightly with 0.8‑1 cm fine soil. Space plants 8‑12 cm within rows, leave 45‑55 cm gap between rows. Thin seedlings to retain only the strongest individuals once they develop 3 true leaves.
Germination Condition Ideal germination temperature ranges 13‑20°C. Seedlings emerge within 8‑14 days. Keep seed bed evenly damp; hot dry soil will heavily slow sprouting progress.
Daily Maintenance Water evenly throughout the long growing cycle, avoid prolonged drought stress. Remove competing weeds frequently, as young scallions compete poorly against aggressive weeds. Hilling soil gently around plant bases can further lengthen the desirable white blanched stalk. Harvest mature giant scallions once stalks achieve full thickness and height.
