They are very small and can be kept in those pots for a while. You will know when they need to be potted on. I doubt they will flower this year and my what a lot you've got. I only have one lupin in my garden and it is about 2ft tall and has had about 6 flower spikes on it.

Those are very immature plants and will take a year or so reach a good size, i wouldn't put them into larger pots for a while yet because they are large pots already, in larger ones their roots will flounder around in all the soil - they need to fill the pot with roots before you think of moving them up a size yet.

thanks to you both ...I will put them back to bed for a while :)

No need to do anything. They have plenty of space for more growing in the pots they are in now. Too young to be planted in the garden and need to grow on a bit more where they are now.

If Anything they are over potted, in other words in pots to big for them, just let them be for the moment. You 'may' be able to plant into the ground in autumn though I doubt it at the size they are. Otherwise keep somewhere frost free over winter.

Thanks for all your comments :)

I am so jealous of your Lupins quantity. I sowed dozens of seeds last year and have only got just one plant out of them. I hope this one flowers next year.

Thankyou so far so good still got a long way to go yet though ..I still have time to kill them all off :) haha..Good Luck with yours too.
