(Question)
I have just removed some leaves on a small hydrangea bush. There are several leaves curled and it looks like little black eggs inside. I have not seen any caterpillers. What should I do to prevent this. I have another bush nearby that is looking very healthy so far. I would be glad for your help. I also would like to know what is an insecticidal soap? Thanking you
