Quick Facts

How to Care for Green Onion

Watering

Keep soil moist; water every 2–3 days.

Check the top of the soil with your finger or a meter before watering instead of following a fixed calendar. In brighter, warmer conditions Green Onion uses water faster, while cool or shaded spots need a longer gap. Water thoroughly until it drains, then empty any water left in the saucer so the roots never sit in it.

Light

Green Onion grows best in full sun light. Keep it where that level stays consistent through the day, and avoid sudden moves that can shock the plant.

If light is too weak, growth becomes thin and stretched; if direct midday sun is too strong, leaves can scorch. Rotate the plant every few weeks so all sides receive even light.

Fertilizing

Feed with a light feed every 2–3 weeks. Always water the soil first so fertilizer does not burn dry roots, and dilute to the strength recommended on the label.

Most plants only need feeding during active growth and should be left alone in the dormant season. Overfeeding causes salt build-up and leaf-tip burn, so when in doubt, feed less.

Repotting

Plan to repot as needed; can be regrown from cuttings. Move into a pot only one size larger, using rich, well-draining mix.

Repot when roots circle the drainage holes or the plant dries out unusually fast. Water lightly after repotting and keep the plant out of strong direct sun for a week while it settles.

Common Problems

Yellow Tips

Yellow leaf tips often mean the plant is overwatered or short of nutrients. Let the soil dry slightly between waterings and feed lightly during active growth.

Bolting

Bolting means the plant runs to seed and stops producing leaves, usually triggered by heat or long days. Keep it cool, water consistently and sow again in a cooler season.

Thrips

Thrips are tiny slender insects that leave silvery streaks and black specks on leaves. Remove affected leaves, improve airflow and treat with insecticidal soap, repeating weekly.
