Seeds
Fast-growing, mild-flavored green onions for a crisp, savory bite in any dish.
Bunching onions, or scallions, are incredibly easy to grow and do not form large bulbs, allowing them to be closely spaced in garden beds or containers. They can be harvested young for a mild, delicate flavor or left to mature for thicker, more pungent stems. They are a staple garnish and ingredient in Asian cuisines, soups, and baked potatoes, offering a continuous harvest if trimmed above the root line.
Light
Grows best in full sun, about 6 to 8 hours a day, and tolerates part shade. Plenty of light keeps the stems thick and the leaves dark green.
Water
Roots are shallow, so keep the soil evenly moist, about 2.5 cm of water a week, without letting it become waterlogged. Water in the morning and mulch lightly to hold moisture.
Humidity
Average humidity is fine. In humid, rainy spells watch for downy mildew and give plants good airflow, watering at the base rather than over the leaves.
Temperature
Adaptable, growing well from about 10 to 35 C. In 35 C+ weather give it light afternoon shade and steady water to keep the leaves mild. Sow from autumn through spring.
Pets and children
Edible and safe for people. Like all alliums, the leaves and bulbs are toxic to dogs and cats because they damage red blood cells and can cause anaemia, so keep pets away from the plants and any trimmings.
Soil
Loose, fertile, well drained loam with a pH of 6.0 to 7.0. Mix garden soil with compost and cocopeat, and use containers at least 15 cm deep with good drainage.
Fertilizer
Mix a balanced fertiliser or compost into the soil at sowing, then give a light nitrogen rich liquid feed every 3 to 4 weeks to build lush green stems. Water and feed again after each cut.
