pesticides and hummingbirds
I used a systemic fertilizer/pesticide and also rose dust on my roses and now I've seen hummingbirds by my roses sipping nectar or eating aphids. Is this going to kill the hummingbirds or harm them in some way?

It depends on what kind you used. Some fertilizers and pesticides could be harmful, while others would not be. Do you remember what it is you used? I would be better able to tell you the effects if you can let me know that.
