Unhappy Lupins leaves turning yellow & red

I bought some lupins from the local garden centre, kept them in the pots they were delivered in for 2 weeks but some of the lower leaves started to turn yellow in the pots.
I put them in the ground hoping they would get a little happier but the lower leaves are now turning red and shrivelling up.
What could be wrong here? Can these be saved? They weren't cheap so don't want to lose them!
You do have new leaves forming from the base so that's a promising sign. I would carefully snip off the red/ yellow leaves at the base and if that is manure around the plant clear it away from the area around the plants.
Lupins can be a little tricky to establish I have found from pot raised plants, I have found better results from just scattering a few seeds around where I'd like them to grow, but that needs patience and you're never sure which colour you will get.
If you have a poorer area of soil you could move them if recently planted. Or you can remove any visible manure from the soil. If you do decide to move them just check that it wasn't root bound, i.e. a tight crowded rootball with roots circling at the bottom. If rootbound just gently scrape a few roots loose with a fork from all round the rootball. Not too much and just on the outside, it will have a tap root forming in its core that should not be damaged, that will help its roots establish.
I'm sure they'll be fine once they get their roots established.
What colours are they @jong? I love lupins, they smell lovely and bees love them.
You did completely the right thing enriching the new soil. New beds need organic matter, well rotted manure, compost, leaf mould etc to give life to the soil. Many perennials would love and thrive in that soil. Some like lupins don't like too much richness that's all. I think they all derived from wild lupins that grow in meadows , so they prefer poorer well drained soil. I'm sure they'll be fine there in the end.
What else do you plan on planting in your new border?
