Shoots sprout and look healthy, get leaves an then start to turn dark right at soil. Then they just drop over.

    Treat them with Neem oil, available at diy stores.

    better drainage and less watering most likely has fungal problems from too much moisture Non-chemical control

    • Remove all affected leaves promptly and destroy
    • Do not allow dead, infected material to remain around the plants, since this will be a source of infection in the following season
    Chemical control

    There are no fungicides with specific recommendations for the control of hellebore leaf spot. However, the fungicides tebuconazole (Bayer Fungus Fighter Concentrate), tebuconazole with trifloxystrobin (Bayer Fungus Fighter Plus), and triticonazole (Scotts Fungus Clear Ultra and Scotts Fungus Clear Ultra Gun) are labelled for the control of a number of other diseases on ornamental plants, and may give some control of hellebore leaf spot .

    Have you checked your garden for cutworms? They do have a habit of nipping stems just below the soil surface and then the plant keels over.

      I'm pretty sure it isn't cut worms. They start to turn dark at the ground level.

    When picking up spotted leaves that have fallen off, be sure Not to put in compost. Pick up ALL leaves and put in trash not in yard debris. When you see a spotted leaf put in garbage immediately. You may need to get rid of some soil and replace with new healthy soil. Good luck
