I started off using shallow tin salad containers with clear plastic lids. Despite being a complete novice, the seeds in all of them sprouted which surprised the heck out of me. I recently transferred them to milk jugs so they'd have headroom. Chances are yours aren't too wet since it's best they're wet rather than dry. Mine were sodden most of the time when they weren't frozen solid back in January & February.
I'm in Z6a in CT also. I WS alyssum back in mid-March. They sprouted a week later and there are are lots of sprouts in the jugs. I'm guessing I got about 60-70% germination.
If you WS them back at the beginning of this month, the weather was kind of weird. Don't give up on them just yet. Some of my milk jugs have a single sprout in them; others look like Chia pets. The seeds know when to sprout better than we do.

Jane, I don't know where in CT you are, but here in my neck of the woods the last week or so has been pretty darn chilly. I had a big wave of sprouts earlier in the month (perhaps even more like the end of March) and I've noticed that I've had nothing sprout in the last week, until today, when the temps went up a bit.

It's supposed to be warmer over the weekend. Hopefully you'll get something.

I'm keeping a sprout chart that captures date seeds were WS and date first sprout appears. There's a lot of action the first couple weeks of April when the weather was mild but it tapered off the 3rd & 4th weeks of the month when the temps dipped back closer to normal. Nothing new has sprouted the past week. With the hot weather they're calling for today and tomorrow, I'm guessing more will sprout next week.
Don't give up on your seeds quite yet. Folks on this forum wouldn't be so enthusiastic about WS if it didn't work.

I wouldn't give up just yet. I have about five containers that hadn't sprouted as of Friday. On Sunday I looked and their are two tiny, tiny sprouts in the one -- I'm glad I didn't dump it, and I was considering it because I'd sowed it it close to six weeks ago. Some things just take their good ole time.

I had some things in a shallow container and they got extremely hot in the sun. There isn't as much air space above the dirt, so when the sun is shining fully on a warm day they seem to get very warm very quickly. I'd move them to a shade/part shade place. My soil got to over 100 degrees on one day, and probably did the same the day before that. (I actually measured it with a candy thermometer--geek.) Some of those seeds, like morning glories, turned to goo while my other MG in jugs did very well. Other seeds, like Chinese aster and some globe amaranth, sprouted anyway. Some seeds, like sweet pea, just won't do a thing while my other sweet peas are growing.

I'd say watch the temps on full sun days.

Thanks for the encouragement. I don't have any milk jugs because I buy it by the quart, but I will have to see what I can come up with. I hope the others sprout. The nice expensive Coreopsis I bought from the garden store last year never came back up and my garden looks pretty bare.

janegael - You're more than welcome to "adopt" some of my sprouts. The folks on this forum were super-generous with seeds and I've got more seedlings than I could plant if I went at it six days a week from now 'til October. There are a lot of WS babies all potted up & looking for homes so if you're interested, shoot me an email. I've got lupine, feverfew, rudbeckia, shasta daisy, lady's mantle, coreopsis, gaillardia, candytuft, hollyhock, and anise hyssop among others.
Like folks on this forum say, the best way to say thanks is to pay it forward.

You said you only drink milk by the quart. You can use the quart containers from milk just like a gallon jug would work. I have several I am using. I hope you get some sprouts out of what you planted. But if you don't, try again. This system really works. What kind of soil did you use? I planted my sweet peas in March and they are already planted out. Since the plants are protected by the container, you can plant seeds much earlier than you would if you were planting them in the ground.

Thank you for all the support and even the marvelous offer. I think my plants got cooked. The heavenly blue morning glories look pretty good, but that's about it. I'm consoled because I wanted them the most. I just adore morning glories.

I can't figure out why I can't grow Love in a Mist that everyone else says they can't kill. Is there a secret to planting them. I have a dog who is a digger and plants I can't kill have a definite charm.
