How to grow onion plants from seed

Onion plants are easy to grow from seed.   There are two many ways.  1.  The direct seeding method is most popular, with seed being sown directly into the beds.  Once your bed has been prepared,  use a wooden stake to dig a shallow furrow along a row.   Sprinkle your seed along the furrow and cover over.  A planting depth of around 5mm is all that is required.  Thin out areas where onions are crowded.  2. The second method is to plant your seed in punnets.   This is a cost effective way to make sure your seed is not wasted.  Use a good seed raising potting mix.  Fill up your punnets and then sprinkle seed over the surface.  Use a light sprinkle of potting mix over the surface and water well.  Place your punnets in a warm sunny spot.  Seeds will pop up around two weeks after planting.  Thin out the weak looking seedlings and then plant out onions once they have reached around 10cm tall.   Plant your seedlings on the surface of the garden bed.   Pre-grown seedlings in punnets can also be purchased from a plant nursery.
