The Lupins in my borders are years old but they are starting to look their age,so after a lot of heart searching I am going to replace them this spring. Has anyone found a good supplier. I would like to go for the bigger pots 5 litres, unless someone comes along with a better suggestion.

hi moon grower, the tubers are on the surface of the soil and look untidy although the flowers are still strong. What would you feed them with ?

If the flowers re still strong they don't need feeding really, can you add a layer of mulch or compost round them? That will also help to hide the roots.

Lupins keep growing year on year... why are you looking at replacing? Feeding the existing plants is easier and does not disturb your border.
