Onion seed planting time

Onion is a perennial herb. It is best to sow it in autumn from September to October. The plant grows slowly. At this time, the weather in most areas is cooler and the seed germination rate is higher. It takes about 15 days from planting to germination.

How to Plant Onion Seeds

1. Land preparation and fertilization: Onions prefer soil with strong fertilizer and water retention capabilities. After choosing the land, land preparation and fertilization should be carried out at the same time. You can use decomposed farmyard manure as base fertilizer.

2. Sowing: Sow onion seeds on the soil, and then cover them with a thin layer of soil and straw at a time. This can achieve heat preservation and moisture retention, and just keep the soil moist in the later stage.
