Lupin Update

So a few days ago I posted about one of my lupins looking like it was about to pop its cloggs (die). The leaves gad all wilted and the flowers were turning brown and limp to one side. From that post David Innes replied and gave me a check list to see if I could work out what the problem could be.... So I did. I looked over the plant to see if I could find anything abnormal above soil level other that the obvious wilting there was nothing.

I then cut one of the stems to see if I could see any discolouring or rot, nothing again. So finally I I dug it up and looked at the roots.

I didn't even need to wash the dirt from the roots to see the problem, large parts of it had turned to a squiggy mush and turned a rotten brown. And where the root met the stem it was semi rotted turning blacky brown and hollow. THATS WHY IT WILTED! The Stems were not getting water nutrition because of this rot.

What caused this, I do not know but all my other lupins will be being watched carefully. It could be disease or it could be the soil conditions i suppose that instigated the down fall of my poor Lupin.
