Greetings from SW CT zone 6, I have realized this Spring an intervention to my native woodlands is needed with some fungicides and organic fertilizers (usually we are pretty hands off and let Mother Nature do her thing). Alas, we have black leaf spot blight on our abundanct laurels and rhodys.

I want to do these treatments all today, and *think* I will be OK after some online searching for answers, but wanted to run it by you smart gardeners first...

1) in Sprayer, use Neptune Harvest with a slighly reduced amount of Copper Fungicide, spraying leaves well. Think we spray where we see disease, but also looks like we should spray healthy bushes to prevent fungus from getting on the,.

2). At roots, Hollytone per application rates, and drenched in with Muracid ( 1 T/ gallon)

Since nothing is really chemical-based, and there are two different application areas, is there any risk that I could be doing damage to the bushes?

thank you in advance for your advice!!
