?What are the best & most economic supports for lupins & advice on how to save them from being demolished ? when weather so changeable.
Be sure the soil is average. Rich soil will make the stems floppy. They support themselves and should not need staking. If they do, you can use bamboo shoots and soft ties.
I bought some bare root lupins online which I planted in a pot outdoors around 3 weeks ago, however the plants don't seem to be growing. In fact, if anything, the very tiny leaves that are on them seem to be dying. I'm not sure what I've done wrong. I planted them using John Innes no.2 soil, I packed the soil down, the pot is in a pretty sunny spot and gets most of the day's sun. Could someone please advise where I've gone wrong and what I need to do to change it please?
That is a very rich soil, and packing it down will make it hold extra moisture while removing necessary air pockets that the plants' roots need to breathe.
I would use a light soil mix (or mix your existing soil with some seed starting mix with little nutrients). Lupines fix their own nitrogen in soil, so any extra can kill them, potentially.
To recap, packed soil, wet soil, and too much nutrients can cause these issues.
Here is an article for more information on the plant:
he stems are bending in half.Please help! I am sending a picture of it. The flowers are coming up Beautiful but leaves are drying up. We are just now planting them.
Getting them planted in the ground probably helped a lot. These articles should help if you are still having problems:

This appears to be powdery mildew. Here are some articles that will help you to treat the disease:
