Damping Off

I would like to start seeds inside.  I have started them, but as soon as they start growing, they just fall over and die. What am I doing wrong?

You are most likely dealing with a fungal root rot, usually called damping off, caused by a soil-borne fungus located in the soil. There are a few things you can do.  First, change your potting mix to a soil-less mixture.  These have fewer fungal pathogens in the soil.  If you are using pots from last year, be sure to clean and sterilize them before using again. In addition, don't overwater your plants.  Allow them to dry out slightly between waterings and maintain good air circulation around the seedlings.
