Question
I thought slugs only ate leaves.  Now many of my wave petunias that I have in pots are wilting.  They aren't too dry or too wet, the only culprit I have are slugs, which I kill constantly.  Could they be doing this damage?  I have tried Safer's but all it does is mildew.

Answer
Petunias are MADE to dry out.

Over-watering is the kiss of death for them.

A textbook case of overwatering.  Stop the madness.  Only water when dry.  Repeat:  Only water when DRY.  I guarantee this is your problem.  It's a common one, and you described it perfectly.

Thanks for your question.
