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!
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!
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.
