Onion seeds are small and black and need to be sown shallowly, approximately 1/4 inch deep in the soil. We use 288 trays and seed 4 seeds/cell. If you use open flats, you may broadcast the seeds. Ensure that the soil is slightly moist but not wet, as excessive moisture can cause the seeds to rot.
Onion seeds require a soil temperature of around 15°C to germinate. Onion seeds usually germinate within two weeks, but it can take up to three weeks in cooler temperatures.
Your onions may be clipped to 4-5" tall prior to transplanting. We transplant out onion seedlings 6" apart in the garden. Keep the soil moist and weed-free.
