Does anyone here know anything about soil borne disease and what to do about it?
I have a new daylily bed planted 3 years ago. Additions to this bed were, compost, alfalfa pellets and maybe some milorganite.
At least half of the plants have little or no roots under them. and no , it's not voles.I didn't notice this last year at all, but this year I saw plants were not thriving, and after looking discovered many had very short clubby looking roots. What do I do now? This is not some kind of smelly rot, I know what rot is. |

| Rather than a disease, this is most likely a pest problem. Daylilies can become infested by root knot nematodes, which will produce the stunted, clubby looking roots you describe and can result in declining vigor and if left untreated, death. Research control methods - a soil drench of neem oil is one recommended treatment. |

| any chance of pictures? It would help us understand what "clubby roots" means. |

| I wish I knew how to post pics. I know it's not root knot nematodes, theres not enough roots left for a nematode to fasten to. |

| Nematodes are microscopic organisms. If there's not enough root for them to infest then there are no roots left at all! |

| You are so right!! Picture a daylily with a few stubs, maybe one an inch long. I am feeling really bad about this bed, I bought a lot of new ones 3 years ago, and the experts say I got something bad in that order. I don't know what to do with that whole bed now,I'm afraid of infecting another part of my yard. I guess I'll dig the rest, throw them, and put down clear plastic to sterilize the soil. Will that kill all the daff bulbs in there too?? Probably. |

| Consider pulling the plants that are left and potting them in some nursery pots with good potting mix. It may not be the soil. I've had some daylilies that just wouldn't thrive in my soil but did great in pots. They found a new home in someone else's yard. |

Consider locating a local resource which can help diagnose the problem.
Among them are the county's university Extension Service office; a nearby University with a Plant and/or Soils Department; a large independent retail nursery; a daylily club and/or specialist. If you can't take in a sample, realize that you can send digital images to just about anyone. Always helps to see what you're talking about. |
