How do you keep pests off from Rosemary? I bought a small Rosmarinus officinalis at a local nursery last summer, and it was healthy and bug-free, but after a few months of sitting on my porch, it acquired aphids, spider mites, and some sort of small winged pest I can't identify. So I sprayed it with an organic insecticidal soap advertised as being able to kill exactly those types of bugs. I've used it on almost all my other outdoor plants, and it's worked very well. However, it seems to only partially work on Rosemary due to its leaves, which curl down and inwards, greatly lessening the effectiveness of spray. Even when I try to spray "up" into the underside of the leaves, I found it very difficult to get the spray into these sheltered areas, allowing the bugs to flourish there while dying everywhere else.
My Rosemary's still alive, but almost all the leaves are now partially dead and pock-marked from the punctures of insects. What can I do to help it?
