Good morning all...I was just out weeding when I noticed 3 ladybugs on my rose-of-sharon. I thought "how sweet" they are good bugs to have around.....Little did I realize why they were there!!!! My ROS is small- only about 2-3 feet high but is very full. One branch was totally covered (they were dark brown aphids? not green)so I trimmed it off but there are sections of a few other branches with the little nasties. So far I only saw 3 ladybugs- will that be enough to control the spread of the aphids? If not, what can I use that won't harm the ladybugs? Thanks all- have a great summer in the garden!!!!!
