small passion blooms brown and die; stink bug problems?
I have a blue eyed susan passion flower...it is growing like crazy, has bloomed a couple of times, and has (had) small blooms coming out on nearly every shoot. but before they get bigger than a quarter of an inch in diameter, they brown and then shrivel up and die. I haven't seen any mites anywhere...i have seen a few brown stink bugs though. could they be doing this? how do I control them? I've tried using ins. soap, but I don't really know what the problem is so I'm not sure how to tackle it. Other than the blooms dying almost immediately, the plant is doing exceptionally well (I have two other passifloras, ruby glow and macrocarpa, and it is outgrowing them more every day). The plant is in-ground. We are in New Orleans, Louisiana. It gets watered regularly. Thanks for your help!
