Question: Howdy, I’m asking about my Lord Baltimore hibiscus. It’s overall healthy and blooming well. But this season, I’ve have had numerous brown leaf spots then eventually leaf yellows and spots turn darker. Now I’m noticing that some flower buds are yellowing and dying out before bloom. It also has banded-wing whitefles with eggs underneath a lot of leaves as well but that’s pretty normal. Not sure if the two are related though. I have treated a couple of times with Neem oil and once with the Bayer Advanced Fungicide/Miticide spray but it hasn’t slowed it down yet. Any other advice you might give?
