How to Sow and Plant
+
Sow Rijnsburger 5 onion seeds directly outdoors from March to April in a fine, well-prepared seedbed. Draw shallow drills and sow thinly in rows spaced about 25 cm apart. Cover lightly with soil and firm gently. Keep the seedbed evenly moist until seedlings appear. After around 6 weeks, thin the row so plants stand roughly 10 cm apart, giving each bulb room to develop. Avoid placing rows right beside radish, cabbage, beans, or peas for a balanced vegetable plot.
How to Grow
+
Rijnsburger 5 onions grow best in an open, sunny position with well-drained, fertile soil. Keep the soil evenly moist, especially while bulbs are swelling, and remove weeds carefully to avoid disturbing shallow roots. As the bulbs mature, reduce watering so the skins can dry and firm. When foliage naturally bends and yellows, lift the bulbs and allow them to dry thoroughly in a warm, airy place. Once fully cured, store in a cool, dry, well-ventilated area for extended use.
Tips
+
Sow Rijnsburger 5 onion seeds outdoors from March to April in well-prepared, fine soil. Create rows 25 cm apart and keep the seedbed evenly moist for steady germination. After emergence, thin seedlings to 10 cm spacing so each plant has room to form a full, round bulb. Avoid sowing next to radish, cabbage, beans, or peas for smoother crop planning. Harvest from August to October when foliage has toppled and yellowed, then dry bulbs thoroughly in a sheltered, airy spot.
