I started some morning glory seeds. Sterized container, new soil-less seed starting mix. The seeds germinated, sent out one long root, didn't even lose the seed coat, then the stem, just above the line of the seed starting mix turned brown and shrivelled up. Once I saw they had germinated I took off the cover, should I have left it on longer? I still have one seed that hasn't keeled over yet, should I remove it from that container and try to transplant it to another?
I'd transplant the remaining seedling and give it a drink of water with hydrogen peroxide (1 tablespoon of standard 3% concentration per quart of water) or weak chamomile tea (both are anti-fungal agents). Make sure your potting mix is just moistened, not soggy wet. Some people put a fan blowing on their seedlings for better ventilation, which can also help.
Thanks Jill and Mel,
I transplanted the remaining seedling in a new clean pot with new mix. I'll have to run out and get some hydrogen peroxide. Keeping my fingers crossed that this last one makes it!
Good reading ladies, thank you. I have a question to add. I have what appears to be the beginning of damping off in 3 containers. I plan to chuck those containers and start over, but I'm wondering if that soil can be sterilized and reused?
I probably wouldn't re-use soil that you know had fungus in it, especially for seed starting even if you sterilize it. Unless you absolutely can't afford to buy new mix, I would buy new stuff instead (make sure you sterilize the new stuff too before you start).
I use hydrogen peroxide in the water to water from the bottem of my seed pots. I start to use this mixture as soon as I plant the seeds. I don't water from the top at all. Since I have been doing this the past couple years, I do not have dampening off at all. I don't sterilize my soil either. I also don't cover up my pots either. But this is just my way of doing things. I had dampening off bad a few years ago and found this method to really work.
Edit to say that I just mix water and a shot of hy. per. to the water.
I asked this question a while back... there are some good answers in this thread
Chamomile Tea and Peroxide and a fan are being tested out here
and thanks critter for the starter soil advice... I am going to try that... some of my mix is showing signs of mold even after the peroxide and tea... I put some of the peroxide in a small sprayer and just hitting the parts that are going funky... so far it looks like it's helping
