I have some lupins in 5" pots (23/9/12) growing quite strongly outdoors.Should I plant them out into the garden at this time of year (NE Scotland) or keep them in the pots outdoors or put them into the greenhouse over winter? Thanks.
Thanks Christopher - I thought it would be a bit too cold up here!
And inspect around pots etc for marauding snails!!!
Yes, I agree - in a greenhouse over winter. And make sure that they are good-sized plants when you put them out, and protect from slugs and snails.
I'd like to know the secret to growing lupins. I've tried them in the ground in various parts of my garden and they just don't survive, let alone thrive. This year I tried again in a pot and those curled up their toes too.
I have very fertile, alkaline to neutral loam and very hard tap water. Do they need acidity? Better drainage? What? All advice welcome as I plan to try again from seed next spring before giving up.
I have some young lupins which I now plant out in tubs surrounded by slug defence.They have done better in pots as my soil is heavy(clay) and been unsuccessful in keeping them but in the pots they are doing fine,they will die back and hopefully flower next year.They are a biannual so take two years before flowering.
Thanks FR and Chris. I have a well drained, sunny patch on the side front which is more neutral then the rest of the garden and may prove to be a better home. I'll try them there and not water them after planting.
Hi I have quite a few lupins I've grown fron seed, They are about 9cm high now. When is the best time to plant them out, also do they like potash as we have a wood burner and I was thinking of scattering some ash around them to deture the fflipping slug and snails. Any advice much appreciated.
I will be waiting til the frosts are gone before I plant mine out. I'll harden them off for a week or two first. I did this last year and got flowers in August, but this year those same plants have happily survived their first winter and I expect flowers in June as normal.
