Growing onions from seed in N. California

Santa Rosa, CA

Is anyone growing onions from seed in Northern California? Can the seeds be sown in September? Do you have recommended variet(ies)? I'm in zone 9 about 60 miles north of San Francisco -- first frost Nov 23rd. Any advice would be appreciated. I do plan to start some onion sets in the spring. But would like to start some from seed now if I can.

Coincidence- I am not in your zone, I am in WA, but I am trying onion seed now also. I bought WallaWalla seeds and sowed them 3 days ago in an empty space in my garden. I figure if they sprout and begin to grow before frost (about 7 weeks away) I can dig them and plant them in a deep tray in my greenhouse. I like to experiment, and not much to lose- so here we go!

I'm also sowing bulb onions from seeds!

My plan was to sow them at the beginning of August and grow on for 12 weeks, then transplant to the garden. I would have been early. Last year, I planted transplants from Dixondale Farms on January 8th and harvest bulb onions between July and August. Had onions up until December. Nice!

Linda, do you grow everything in EBs? I don't use containers unless I really have to- I have better results in ground. What timeline do those photos include?- From sowing seeds to harvest?

Good luck, Jo! We can experiment together and see how we do.

I have nine Earthboxes, and used them last season to grow the onions. I didn't . those from seeds, but from transplants I bought from Dixondale Farms. I planted the transplants out on January 8th, and started harvesting in July. I harvested the onions in late August .

The Baton Gardener has a tutorial on YouTube on growing onions from seeds n. He's som ewhere in Louisiana, and started seeds in a trough filled with sifted compost. he started his seeds in August I think and planted them in October, 12 weeks later

I'm starting mine this weekend and planting them out into the EBs in 12 weeks. Then, going to start a 2nd batch in October to coincide with my original planting date of January 8th.

I used the EBs as space savers. Now that I have two raised beds , I'll use the EBs as for my mustards and collards.
