Reply To: Damping off with seedlings

[Mick104]

Hi Pavol, first off the fungus growing on the surface is probably not causing the damping off , D/O is caused by pathogens in the soil. For the blocker mix, my compost is about a year old (hot composted) and the peat is new. I use plastic trays which are washed before use but not sterilized. I germinate my seeds in a cloche in a poly-tunnel so its a damp environment but I never have issues with damping off. All that is of no great help to you . I think your problem is with one of your ingredients or are you reusing wooden trays ?.
