Raising Lupins from seed.

So I set some of this year's Lupin seed......nothing happened....
I then scarified some as they are like tiny bullets they germinated In days.
I am trying to grow everything I can from seed ,because of cost.
Anyway they are looking good and I now have to keep them through the winter.
Cold greenhouse or outside?

 

Look good roders, I'd go for the cold green house, easier to keep a bit dryer and less slugs.

 

It looks like you have plenty so maybe you could try an experiment - put one tray outside in a sheltered spot and see how they do compared to the greenhouse ones.

 

Its why some of us have cold frames,' half way house'.If you can protect from the ravages of winter and predations of slugs, the ideal is to limit new leaf but build the number of rootbuds to enable you to pot on in early Spring, to achieve a bigger plant by May which can withstand the outside world. Do not try to force them to be like those you will see in garden centres with established flower spikes- you want them to survive and flourish, not sell, flower and dwindle !

 

I’ve kept them outside overwinter before I had the options of a greenhouse or cold frame. Just kept them tucked in somewhere sheltered, mine were tucked in next to some larger containers against a fence which is away from the prevailing wind.
