Wow...seedling mania! =) They are a bit leggy, but not as much as many others i've seen. Simply provide them plenty of light (preferably sun, if zone permits) & replant leaving about the top third above the soil (if you have the time...that's a lot of seedlings!).


Thanks for the advice Dave. I've been leaving the lids open for a couple of hours at a time. While the white stuff hasn't disappeared, I think it might be lessening but happily the seeds have actually started to germinate and the seedlings are beginning to poke out :-)
I guess they didn't get too grossed out.

Much too involved to try to give you a list, it's best to look up each plant on a reliable germination database for suggestions.
Here's one that's good although the suggestions are most often for seed that has been dried and stored or purchased commercially. Seeds freshly harvested may have different requirements.

Yeah I'm sure I planted columbine. I collected the seed myself and I have so many different types that I collect alot of it. I've just never planted any before. I guess I expected tiny little columbine looking seedlings LOL. They currently are tiny, and each have 2-3 leaves, but don't look like columbine leaves. Outnproud, I have 82 varieties of sedum lol..but the only sedum I would say these look like is maybe a sarmentosum, but in shape only not texture.
I'll take a picture and post it that would probably help.

I JUST SUCK IT UP AND BUY THE 72 CELL TRAYS. (sorry caps) ive tried other el-cheapo methods, but i always wish i had trays with tops once the weather warms up enuf to put everything outside during the day... i get a few years out of them, so i just buy 2 or 3 every year and keep the rotation going... watering with in-town tap water keeps disease and green slime at bay :) for only 4 bucks at dollar general, i dont want to bother hauling 500+ single seedlings in and out every day for 2 months

I have been planting artichokes in my zone 5 garden for 10 years. But the variety of seed you purchased might be very important. I've been planting imperial star hybrid that were bred for setting flowers (you eat the flower bud before it opens) the first year from seed. I have no experience with other cultivars. Its not too late to plant your seed for fruit production this year if you have the imperial star seed. You may inquire of the seed company of origin if you have another variety.
I don't know the viability of artichoke seed but I always have seed left over from the previous year which germinate quite successfully for me.
I plant my artichokes right in the ground. I don't think you'll have to worry about summer heat in your zone, after all they're grown in California and in the Mediterranean. They like good soil and adequate moisture, and many people say at least 15 days in cool temps (40F-50F) in order to set fruit. I've had fine production without this "chill period".
Good luck. I planted 25 seeds this year. Hoping for enough to pick them very young when the whole thing is edible, and maybe some for freezing as well.

Wanted to clarify.....
Start seeds in pots indoors beginning of March, then transplant into the ground after danger of frost. I do not plant them in pots so I can move them around. No need to do that. I've tried overwintering them with little success. Its easier to start them form seed each year.

Mimosa's require dark and 80 degree soil to germinate. Constant bottom heat until roots are well established also helps. Nicking the seeds with an exacto knife or razor blade helps but isn't really necessary. Plant 1/2" deep in good moist potting mix (not dirt) and cover so light doesn't get to it. I use several thicknesses of damp newspaper.
Good luck.;)

Someone asked about these several days ago for seed starting - Checking Terracycle website then shows the 'organic soil' in which to start the seeds is pure worm castings. Should already provide nitrogen, potassium, calcium, magnesium, iron, other trace minerals. The cells are quite small, you may not want/need to add additional fertilizer while your starts remain in them.
Let us know how your seedlings do - I haven't used or known anyone who has used them but it seemed like a fairly rich environment for starting seeds to me.

Be sure to review all the great FAQ's here too as they cover all many questions in detail. You'll almost always find the answer to any basic question covered there.

Quirkpod, that true of most seeds - they should be harvested when ripe and not left on the plant all winter. I'm surprised there were still intact pods on a tree peony after facing winter - usually they would have split open and spilled onto the ground by at least the first Fall storm.

Just got this from a grower, Cricket Hill Garden:

Standard flats (trays) are 21x10.5. Is that what you need? If so most all of the xommon seed companies like Gurneys, Harris, Johnnys, Jungs, etc. offer them or if you want bulk quantities check out Novosel. They have good prices on all the basic equipment.
Otherwise your best bet is one of the greenhouse supply companies like FarmTek or Charleys.

Dave,
Thanks for the response. I'm looking for 8 x 20's or 12 x 20's to hold 4" square pots. It's such a waste of space under the lights to use 1020's. The closest thing I have found are some cookie sheets that I have that are 12 x 16 but again, they waste space.
