Seth, I don't blame or judge you for going the chemical route. I'm holding that in reserve as a last resort but I am going to try my best to avoid that. I'm going to try the nematodes and milky spore next year in the beds and my entire lawn. I've got dead spots throughout which I assume are from grubs and no doubt they've laid a lot of eggs in my beds. It seems like they've lessened a bit this week. Not sure if it's the neem oil (doubtful) or if the generation is dying. I've got some open blooms that have been left untouched for the past two days.
Carol, thank you it's not fun. You spend time and money nurturing your roses just to have them gobbled up - super frustrating. But honestly compared to your obstacles I'm happy to take the JB's on if it means they stay out of Alberta!
Rosemary, that's an interesting approach I'll have to find that video.
