Bunching onion seeds that I shoulda planted in early March

 Should I plant them now, or wait until fall, or maybe next year (I know
they'll only have 50% germination at best next year.)

I'm in Minnesota, land of the almost midnight sun, and I'm not sure what
the extremely long days will do to a bunching onion seedling.  The
variety is Crimson Forest.

Thanks,
Bob

I'd go for it.  See what happens.  I don't think 'Welsh'/bunching onions
 (A. fistulosum) bulb up much in any case, long days or short.  Or, if
you live in a mild winter area, wait until later this summer and start
them for winter harvest.

(A fresh packet next year would add less than a dollar to a seed order from
Pinetree Garden Seeds.)

I'm in California, and I am holding on to my bunching onion seeds until
the fall.  Day length is not my reason for keeping the seeds --
temperature is.

My vegetable garden book lists minimum, optimal, and maximum soil
temperatures for the germination of several types of seeds.  Onions
prefer lower temperatures.  Minimum temperature = 32°F; optimal =
80°F; maximum = 95°F.

The book cautions that soil temperatures can exceed air temperatures by
as much as 20 degrees.  I wish I had read that part before wasting
seeds and water.  Air temperatures in my area haven't gone above 85°
yet this season, but I'm sure that the soil has gotten significantly
hotter than that.

I tried getting a second round of carrots, coriander, and chicory
started three weeks ago.    I have ONE new coriander seedling.  The
carrot seeds have the same maximum temperature as the onion seeds.

At the same time, I started tomato and cantaloupe seeds.  They have
germinated readily.

Hope that helps!

Thanks.  I just planted the seeds this morning.  When I get home I'll
shade them for about a week so they don't get too hot.
