The usual recommendation for hosta is, if no germination takes place in 3-4 weeks, move the sown seeds, moist, into the refrigerator or outside if appropriate climate/season where they will be exposed to temps of approx. 40F for 2-4 weeks. Then bring back to warmer for germination.
Hello Scarlet,
I bought other seeds online (picea, abies, laburnum,...) and each one had a full specification on how to grow. Very complete indeed.
I believe you should not put these seeds in the fridge.
I have the Eucaliptus in the photo in my garden (not the same kind of Eucaliptus) and this one is quite invasive. If you left the seeds in the soil they grow easily.
Let's see if with our seeds it works in the same way...
I am going to make an experience with 50% of the acorns I collected and put in the soil, as referred in this page:
http://anpsa.org.au/eucal2a.html
The others 50% I will just throw to the soil and wait.
Temperatures here in Portugal around 20 - 30 Celsius during this period of the year.
Fantastic site ampa62,
I'm going to try the bog method, fingers crossed! I will keep you posted on what happens ... or doesn't happen. The temps at the moment are so slowly receding at the moment we're at 70's range rather than 80's which is utterly wonderful in it's own right.
I really hope our seeds prove their worth here. Let me know how you get on with yours, it says general 2-3 weeks. That's hardly anything.
I'll start 2 tonight and see how we get on. :)

Hi Marly and welcome to GardenWeb!
Well, some seeds seem to germinate best in light and others germinate better in darkness. So, a lot would depend on what herbs youâÂÂre growing. You might find the link below helpful in that regard. Even when light is required for germination, very little is usually needed. I would think that if that opaque box is outside (but out of direct sunlight) enough light would be available to the seeds.
What you need to keep an eye on is the condensation within that box. If you see water droplets forming on the underside of the lid, itâÂÂs too wet (seeds might rot). A little moister is good, but not large water droplets.
If outside, make sure the box does not get too hot (75 degrees F. should be about right). Also, during the germination period, remove the lid once in awhile and let some fresh air into the box. Once the seeds start to sprout, the lid should be completely removed.
Hope this is helpful,
Art

FWIW, I don't dead head my pansy or viola's. They have been forming seed pods which have been bursting all year. So mother nature is sowing them all summer for next spring.
What that means is sow whenever you are ready as they will germinate when conditions suit.

Hi All
Just wanted to give you an update on the Ipomea that you all gave me advice on.
I can't believe that i actually had some success with growing them , after years of not getting past the germination stage.
I found that i was planting them too early as the packet suggested, in April, I planted them end May and this seems to have worked, I found that they produced an abundance of leaves(first pic) and the flowers seemed to appear under the leaves so were very hard to notice among the dense foliage. Only a few flowers have come out, although there are many buds. I guess it's the Leeds climate!The same thing has happened with some cup and saucer seedlings. Lots of foliage and buds, but no flowers. I've added a couple of pics for you to see. Cheers and thanks for the advice it really helped.
After posting my questions, I saw there's also a forum on winter sowing.
If seeds of Cora or Cora Cascade vinca series are candidates for winter sowing, I'd be interested in learning about this as well as sowing it in the "regular" way.
If you think I should post this part of my questions in the forum on winter sowing, please let me know.
I have always had a hard time with asters, until last year. I tried Tower asters and they germinated really well. This year I sowed them again plus a different aster and again the towers germinated fine, the others, I think I have one that germinated.
I bought 8 different types of petunia seed this year, 5 of them I got close to 100% germination, the other three I got zilch. Which has never happened to me with petunias before. Avalanche Red, Denim Shockwave, and Baby Ducks - total loss.
It's weird how sometimes things work and others they don't! I have been using the farmer's almanac gardening by the moon this year just for fun and I haven't had any failures aside from forgetting to water something too long :( I actually have an Ipomopsis flowering now!! I also have some successful moonflower vines this year which I haven't had luck with in the past. I think if we keep trying we eventually are successful!
It doesn't sound like your planting medium is good for container gardening. The topsoil and compost holds too much moisture and is effectively drowning the plants. You will need to look into a "potting" mixture.
Second a majority of what you listed are 'cool' weather crops (you can google that) and will do better in the spring and fall before it gets really hot.
Good luck

Not sure what climate you are in but here in Cambodia you can gently press the fresh black seed into the ground anywhere with reasonably good, well draining soil, forget about them, and a month or so later you'll have a decent seedling. I "found" a 2 foot tall tree today that i literally did nothing for once the seed was in the ground. So the black coating doesnt inhibit anything that I've observed, at least not in the tropics! Good luck.

I have about 10 plants I planted from seeds. That was about 11/2 years ago. Now they are about 1 ft high. I have had no problems with them. Even in the winter time when temps get in the mid to upper 40s a couple of times they did great.
I live in SW Fl. and we have hot humid summers, so conditions seem to be very good. I do give them some plant food once every 3-4 weeks. I plan on keeping them in pots until they get about 6-7 ft and then put them in the ground.
Once you get some seeds growing, you will never have to worry about starting any more seeds! My yard is almost 'weedy' with all the multi-colored 'rainbow' 4 o'clocks that seem to be perennials here as the large tap root regrows again each year. The pretty mixed colors on each flower as well as on the same plant are so fragrant & beautiful ... not as boring as the single colored varieties! The mixture of colors seems to get even more mixed with the years & I try & save as many seeds as possible to give to my neighbors & relatives. Good luck!
I have found the best way to start four o'clocks from seed are to plant in the fall. Just make sure you mark where they are. Sometimes they don't flower the first year. But, they are very aggressive once they get started and return year after year. They do readily reseed every year also.
