Lupin from seeds
I'm a total and utter newbie and apologise if I've posted in the wrong place for this. Basically I want to try to grow lupin from seeds and was hoping somebody could give me an idiot's guide to what I need to do? I've googled this extensively and can only seem to find websites that assume people have some knowledge/experience and I really don't! My dad says to buy one from a garden centre but I'm a new garden owner and can't afford to spend much on plants (plus it's basically a blank canvas at the moment so will take a lot of filling).
So for lupins, can I start growing in my conservatory or will it be too cold at night?
I've seen an article that says to soak the seeds in water for 24 hrs before sowing and then harden them off before planting out in May but I don't know what to plant them in and when I would need to transfer them to a pot? Also, what actually does 'hardening off' consist of and for how long?
Sorry if I sound completely dense!
Also, if anybody has any tip for good plants to grow from seeds then that would be much appreciated.
Thanks in advance
