damping off

Hi hope someone can help me,
I put my seeds in and they all came up. I then planted them out into some potting mix so I could control their sunlight etc, until they were big enough for the garden.
All of a sudden they are rotting from the base up, which to my understanding is damping off.
What causes this? I have sprayed some fungicide on them, as I had no idea what else to do.
Could it be the potting mix, I think it was fairly old. I am hoping to find the cause to stop it happening again as I lost close to 30 seedlings!
With thanks Emily |

Damping off is a term for the effects of several organisms - all water-borne. Since you've already used a fungicide there's little more you can do for the existing seedlings except keep them dry and in a spot with plenty of ventilation. By dry I mean not kept too moist.
If you plan to sow more seeds I'd thoroughly clean the seedling trays with a bleach solution. Hygiene is the best preventative measure - clean equipment, sterile seed raising mix and clean hands. |

| I had terrible trouble with conifer seedlings suffering from damping off, so I planted them on top of the potting mix then covered them with medium coarse river sand and never had a problem with those particular seeds again. I would try the seed raising mix - better air circulation and no trays of water around. |

| Hi there sea weed spray , compost, sprays, drenches are good to control pythium. You can also try a product called Anti Rot. |
