Growing onion from seed

8 years ago

I know it' n the right time, but in the past I have the hardest time growing onion from seed. I start the onion seeds in basic little containers and fill it with seed starter mix. Germination is fine until they get about an inch or two and the roots start lifting from the soil. It happens every single time. I tried sowing them in my garden one season but the exact same thing happened. Any tips or advice?

Not usually difficult. Sounds you were doing it right. I use a flat 2-3 inches deep filled with Promix or similar and just sow the seeds. Takes about 8 weeks to get to transplant size. They don't like wet feet so you may be overwatering. If you are starting inside it may be too warm for them.

That would be my guess too - overly warm, especially the soil temps. Onions like cool early spring temps in the garden and also in their 'indoor' pots.

If some of the roots are above the soil you can just take a pencil and push them back under.
