    Problems with all my droseras

    I have 4 drosera species; capensis, aliciae, spatulata and binata.

    Every drosera i grow have the same problem. The new leaves dry brown.
    and the plan became very hard, like a stone. The leaves cannot develop, and the plant die after a week or so.

    Drosera spatulata
    you can see the upper plant, in the center. Its brown/dark and the plant will die soon.
    I got this on each drosera. I sow some d.aliciae seeds, and the seedling have the same problem.
    I use demineralized water as always, the temps is good, rh too.


    all my others cps are healthy.

    any idea ?

    Just guessing, they're too close to the lights and are burning.

    As Mato said, they look like they could use much more light. Try bringing the plants closer to the lights, or upgrading your lights to a higher wattage.

    I don't know what the hard leaves are from, but you plants look like they could use better (or worse ) quality of soil. I use premier peat moss brand, and I always wash it for indoor Drosera. there are a couple of better brands of peat moss but I forgot what they are called.

    The silica sand I mix with the moss is probably around 20 grit, and I wash that too.

    Hope this helps!

    personally i dont think it's a light issue at all, and for the most part, this seems to frequently happen to D. aliceae, but i've seen it on other rosetted sundews.

    tanic acid accumulation is occurring. often happens when humidity is high and you didnt rinse out your peat thoroughly. you can remove it by squirting lukewarm water at the crown. it must be removed sooner rather than later otherwise, the crown will die.

    look at the second topic/question on the page

    If D.Capillaris is anything like this species, it grew a lot better in a peat sand mix, but I never did wash it out.

    I use 2x64watts with reflector. I dont think its a lightning problem, like amphirion say. I saw the 2 links you shared here, very nice info!
    I will always wash my peat and sand (perlite vermiculire too?) Before using it.
    The bad new is, now i have to change the soil of 25 droseras lol


    Thanks a lot guys !!

    Ugh, I feel you. I recently changed the soil and pot size of most of my Drosera collection. It took forever to wash and re-make all of the soil, but it's definitely worth it once they start to grow.

    Good luck!
