    Unprecedented

    Hi everyone. Last year I started having a problem. All the leaves on my Drosera and VFTs turn black while the growth points remain green. Whatever it is has killed nearly ALL of my Pings. I assume it's the same thing that has been knocking off my Sarracenia as well. I thought the problem was gone, but it recently came back. All of these plants looked great a few weeks ago.










    I've never encountered this problem in all my years of growing. I'd greatly appreciate any help. Thanks.

    Ouch...those plants look pretty bad.

    Have you sprayed them with anything lately?(pesticide, foliar fertilizer) That happened to my sundews once, when I sprayed them with a fungicide. One died, but the other fortunately grew back from the roots.

    Have watered with Captan and Cleary's. Other than that, nothing else.

    Oh man, that's painful to look at. I'm not sure what's wrong, but if I were you, I'd probably do a massive repotting. No more fertilization or treatments, and all new media.

    EDIT: Also, I'd probably trim off anything that's black. Amputations all around.

    Well, it's affecting a large portion of the collection. Repotting and trimming is not gonna happen. Besides, I repotted a lot of them when it first appeared. It came back anyway.

    Can I ask about your water source? Seems like the ends of the plants are dying first, reminds me of heavy metals with aquatic plants.
