Onion Microgreens produce fine, upright green shoots with a fresh onion flavour and mild sharpness. Chop them over salads, sandwiches, wraps, raita, eggs, rice, noodles, soups, dal and cooked vegetables.

The shoots grow slowly at first and become taller after receiving light. Their slender shape and clear onion flavour make them useful whenever a small amount of fresh onion taste is needed.

Why Grow It

• Onion Flavour: Adds fresh onion taste without large pieces.
• Fine Shoots: Slender green leaves are easy to chop and serve.
• Many Uses: Suitable for fresh and cooked meals.
• Small Space: Grows in shallow trays and small containers.
• Year-Round Growing: Suitable for indoor growing during any season.

Best Conditions

• Germination: Usually 5–10 days
• Harvest: Around 18–25 days
• Temperature: Around 18–24°C
• Light: Bright, indirect light after germination
• Tray: A shallow tray around 1½–2 inches deep
• Seed amount: Around 30–40 grams per 10 × 20-inch tray
• Seed soaking: Not required
• Growing mix: Coco peat or fine seed starter mix

Onion Microgreens can be grown throughout the year in Pakistan. Keep the tray in a bright, airy indoor or sheltered location. During hot weather, use the coolest available place and protect the shoots from direct afternoon sunlight.

How to Grow

1. Fill a clean shallow tray with 1–1½ inches of moist coco peat or fine seed starter mix.
2. Spread the dry seeds evenly over the surface and press them gently against the mix.
3. Cover with a thin layer of growing mix and mist the surface thoroughly.
4. Cover the tray for around 5–7 days, checking daily to keep the surface lightly moist.
5. Remove the cover when most shoots appear, then provide bright indirect light and water from below.

Plant Care

Onion seeds may emerge gradually, so keep the growing mix lightly moist throughout germination. Avoid uncovering the tray after only the first few shoots appear.

Once uncovered, add water to the lower tray whenever the mix begins drying. Rotate the tray daily for straighter growth and provide gentle airflow during humid weather.

Extra fertilizer is usually unnecessary during the first harvest.

Local Gardener Tips

• Do not soak the seeds before sowing.
• Spread the seeds evenly without forming thick piles.
• Use a fine growing mix without large pieces.
• Keep the tray covered until most shoots have appeared.
• Start a new small tray every two weeks for a regular supply.

Harvesting

Harvest when the shoots are around 3–5 inches tall, usually 18–25 days after sowing.

Use clean scissors to cut them around ½–1 inch above the growing mix. Avoid including roots or coco peat with the harvested shoots. Rinse with clean water, drain well and chop as needed.

FAQs

Why are black seed coverings attached to the tips?

The black pieces are the original seed coverings. They often fall away as the shoots grow. Any loose coverings can be brushed off gently before harvesting.

Why are some shoots bent or shaped like loops?

Onion seedlings often emerge with their tips still held near the growing mix. They usually straighten as the shoots grow and receive light.

Will Onion Microgreens grow again after cutting?

Some shoots may regrow if the lower section is left in place. The next growth is usually thinner and less even, so a newly sown tray gives a fuller harvest.
