Will my seedlings survive the winter?

I have some very small seeds that have just came up I have placed them in my greenhouse and have no clue if they will survive winter should I keep them in the house or will they be fine where they are?

x1 Eryngium alpinum
x1 cyclamen
x6 Astilbe arendsii 'Showstar'
x3 lupins, these are growing fast!

 

They are rather young and wouldn't risk them with frost, so yes I'd bring them in and put them somewhere bright but out of sunlight.

 

We've had, and continue to have unusually warm weather for the time of year. That means your seedlings will be a bit soft. Trouble is, as we're now so late in the year, once it does cool down. most likely it will do so very suddenly, so later this week or next week, chances are it will suddenly drop to normal November temperatures, catching out your seedlings. I'd bring them in and keep them on a cooler windowsill.

 

Thanks I will take your advice as I really dont want to loose them.

 

Is your Cyclamen one of the hardy sort like Coum?If it is then you can leave it in the pot in a cold greenhouse and as long as you keep the compost slightly moist it will do its own thing and then when it is ready will die back naturally so don't think it has died as it will come back next Autumn a bit bigger than this year

I bought some pots of hardy Cyclamen a few months ago and there was opened seed pods on top of the compost so collected them up with a pair of tweezers,washed the seed in some water and washing up liquid and sowed the seed in trays and then lightly covered them with compost.They are coming up like weeds now

As others have said best not put the seedlings outside as we are due a hard winter ie snow and heavy frosts so don't want you to lose them at this stage

 

Yes they are Coum I have about 12 in the shed but only 1 has came up so far.

 

Don't worry as one of my shallow trays looked like there wasn't anything in it but then the other day they started to shows the first leaf.The seeds are coated with a substance that can delay germination hence the washing of the seeds and also I found out the seeds don't like to be exposed to the light,hence the covering of the seeds with a sprinkling of compost
