Question
I have both mites and mold on my zinnas, which are out in front of my office near the street. Got any thing I can do to get rid of either the mites or the mold?  Thanks

Answer
Hi Lee,
Thanx for your question.  Mites can be controlled by miticides or horticultural soap.  To keep mold off of zinnias, don't plant them too closely and avoid watering them from overhead.  Here is a link from the University of Wisconsin-Madison that has a lot of information about zinnias.  I hope this helps.
