Full Product Description

Purple onion (Allium cepa) belongs to the Amaryllidaceae family. This popular bulb vegetable contains abundant antioxidant substances. Mature purple‑red bulbs serve as common cooking seasoning and fresh salad ingredients. Its green young shoots are also edible.

All seeds go through repeated screening to remove shrivelled, broken and low‑viability grains, ensuring sturdy seedlings and well‑formed round purple onion bulbs.

Packaging & Shipping Notes

Tiny onion seeds are sealed inside thick moisture‑proof inner bags. Outer carton cushioning prevents seed loss and extrusion damage in transit.

Keep packages away from high‑temperature enclosed storage, damp surroundings and prolonged direct sunlight. Reseal leftover seeds tightly and store within cool‑dry well‑ventilated zones.

Planting Guide

Best Sowing Season

Sow in early spring or late autumn. The suitable growing temperature ranges 10℃‑20℃. High‑temperature summer weather stops bulb expansion.

Seed Pre‑Treatment

Soak small‑sized seeds in room‑temperature clean water for 6‑8 hours
Discard floating inactive seeds
Mix fine seeds with dry fine sand for even broadcasting

Soil Requirement

Clear weeds and stones, deeply loosen planting soil. Loose, fertile, well‑drained neutral sandy‑loam works best. Heavy compact soil easily causes deformed onion bulbs. Avoid water‑logged land.

Sowing Operation

Spread the seed‑sand mixture evenly, cover with 0.08‑0.15‑inch thin fine soil and gently compress the topsoil layer.

Germination & Seedling Care

Maintain moderate soil moisture. Healthy seeds germinate within 7‑12 days under suitable cool‑moist conditions. Thin seedlings timely and remove weeds regularly.

Daily‑care for Mature Plants

Plant under full‑sunshine surroundings; sufficient sunlight promotes bulb enlargement and deep purple skin colour. Keep steady soil moisture and add potassium‑rich fertilizer during the bulb‑swelling stage. Stop watering when the leaves begin to wither before harvest.

Seed Storage & Package

Moisture‑proof sealed packaging protects seeds against dampness, mould and shipping‑caused damage.

Store spare seeds inside cool, dry, shaded and ventilated locations. Refrigerated storage suits long‑term preservation and stay away from hot‑humid surroundings. Sow seeds within three‑month storage for optimum germination‑rate.
