Growing Onion

Hi I've planted onion seeds directly into the garden bed and then mulched over the top. Should I have waited until the seedlings grew before mulching? I've heard that like carrots you are supposed to thin them out? What should I do? TIA

Mulching over seed will not allow them to germinate and then push through to the sun. Onion, lettuce and carrot all grow well together (The Three Sisters) and need to "see the sun" to germinate well. I plant the three mixed together thrown over the bed and then water in stirring the top 5mm of soil in the process and then keep moist with a misting rosehead. They will then come up thicker than hairs on a cats back and effectively do not need mulch until you have thinned out the baby carrots to allow bigger ones to grow. Lettuce you can pick and let come again while the onions slowly get bigger. Trim dead and yellowing onion leaves to encourage more growth.
