Two lupins in the border next to each other, one is thriving the other yellowing and small. They're nothing special, I can't remember what colour but probably bog standard mauve/ blue. What can I do to strengthen the poorly one. Soil is alkaline and reasonably free draining although it is soggy with all the 4ain.
