Step 1: Soak and Sow – Start from the Seed

- Soak seeds:
Soak purple onion seeds in warm water for 4–6 hours. This helps soften the seed coat and stimulates stronger, faster germination.
- How to sow:
Use a seed tray or small pot. Sow the seeds 0.3–0.5 cm deep in loose, well-draining soil mixed with organic matter. Lightly cover with a thin layer of soil and gently mist with water to keep the surface moist.
- Tip:
Purple onion seeds can be sown year-round if temperatures stay between 20–30°C. Keep the soil slightly moist, avoid waterlogging, and place the tray where there is gentle sunlight. If the weather is too hot or rainy, provide shade or a cover to protect the seedbed.

HOW TO PLANT

Step 2: Care for Seedlings – Help Them Grow Strong

- Light:
Place purple onion seedlings in a location with 4–6 hours of direct sunlight daily. If growing indoors, a bright window or grow lights will also work well, as onions love light to develop strong bulbs.
- Watering:
Keep the soil evenly moist, especially during the early growth stage. However, avoid overwatering, as purple onions are sensitive to waterlogging, which can cause root or bulb rot.
- Transplanting:
When seedlings develop 2–3 true leaves (about 10–12 days old), gently transplant them into larger pots, foam boxes, or directly into your garden bed. Make a small hole, place the roots in, cover lightly with soil, and press gently to help the plant stand firm.
- Fertilizing:
Apply balanced NPK fertilizer (10-10-10 or 15-15-15) or organic compost around the base to strengthen roots and promote healthy leaf and bulb development. Avoid applying too close to the stem to prevent burning.

Step 3: Planting in the Garden and Harvesting – Keep Fruit Coming Year-Round

- Spacing:
When transplanting purple onion seedlings, space plants 8–10 cm apart, with 20–25 cm between rows. This allows enough room for bulbs to expand without overcrowding.
- Care:
Water consistently to keep the soil slightly moist, especially during bulb formation. Apply fertilizer every 15–20 days using balanced NPK or organic compost. Remove weeds regularly so nutrients are focused on bulb growth.
- Harvest:
Purple onions are ready to harvest after 60–70 days. When the leaves start yellowing and falling over, the bulbs have matured. Pull them up gently and dry for 2–3 days to enhance color and shelf life.
- Tip:
Purple onions grow best with full sunlight (4–6 hours/day), moderate watering, and well-draining soil. Reduce watering slightly during the final 1–2 weeks to help bulbs harden and develop a beautiful purple skin.

Harveste fruits retain natural flavor and rich nutrients

Organic seeds allow you to grow purple onions without harmful chemicals, ensuring that the bulbs are clean, safe, and healthy for your family.
