Neem Oil Question
I've sprayed Neem oil on a couple of rose shrubs, and also on Gold Euonymus shrubs. Is this oil relatively a safe oil to spray on other shrubs/trees such as crapes, loropetalums, etc??
My Euonymus' get scale on them which Neem is good for, but I was wondering if it were also good for invading leaf pests such as aphids, etc? Thanks.
