    Does anyone know why new seedlings suddenly wilt and die? This always seems to happens when starting under a plastic domed tray.

    I've started some plants and just want to prevent this ahead of time.

    Could be:

    cold
    heat
    dryness
    too moist
    Not proper "start" soil


    Do they wilt and die before or after you put them in soil?

    It is because the humidity. A dome over the soil creates an enviornment of 100% humidity which makes it especially easy for fungus to grow. Google the type of plant you are interested in growing for further intructions.

    I often start plants indoors; with some trial and error I've found that you'll get the best results if you leave the dome on until the seedlings just break the surface of the soil. As soon as that happens, move the lid so that it is open a crack and every few days, make the opening a little wider, making sure that the soil remains damp, but not sodden. After 10 days or so the container will more open than closed and you can get rid of the lid altogether. Good luck!

    What sort of plants?

    And what do you mean by wilt/die? If they get a "pinch" at the bottom of the stalk, then the problem is called rot-off and is a fungus. If the whole thing is shriveling up, then it's probably drought.

    Thanks for the advice. These are specialty geraniums, rudebeckia and coneflowers, that I am trying out.
