potted up then damping off

b54red · April 6, 2010

This has never happened in the many years I have been potting plants up from seedlings. This was my third batch of seedlings I potted up just last week and had a bunch die from what looks like damping off. I was using very healthy seedlings with no sign of the disease. I have had no damping off in the hundreds of seedlings I have started this year; but it hit the last batch I potted up. They were in the greenhouse with a fan on intermittently with plenty of light and in the same potting mixture used in the last couple of batches. I sprayed with daconil when I saw so many dying plants and it seems to have slowed it down. Has this ever happened to anyone else? It has been unusually warm this past week; but I always associate damping off with cooler conditions and too much water. This batch was treated just like all the others which thrived. Oh well another tomato mystery.

Yes, I had the same problem this year. Like you I used the same soil, same growing conditions and can not figure out what went wrong. Maybe someone will chime in with their experiences.

Physan 20 is a good product to have around when something like this happens. You can also spray your seedlings with it when you pot up if so desired. Ami

Someone in another thread here mentioned dusting with cinnamon for damp-off. I tried some on a few that were already up and dusted just about all my flats as I planted.

So far this is the first year I've had NO damp off at all. Was it the Cinnamon ? I don't know but I'll use it again until it doesn't seem to work.

Use 1to2 parts household hydrogen peroxide and 10 parts water and spray the soil and plants.
This kills the micro critters that attack the plant stem at the soil level.

Worth, I remember you posting that info in the past and that is what I have done to all my plants. They do look better, I will hopefully remember to spray earlier next year.

Still a newbie

Thanks for the idea Worth. I'll try anything within reason. I'll try it next year and see if it helps.
