Dampening off in tomatoes
Mary Alice
If you keep the top of the soil in seedlings constantly wet, you're likely to get dampening off, the common name for one of a number of fungi that thrive in moist conditions and kill your seedlings. Make sure you've got good air circulation and bottom water your seedlings allowing the top surface to remain dry. We're seeing little dampening off this year but I took a photo of the one plant I found with this ailment.
