Probably too late for you but..............Lupines usually do best in full sun. With regular Summer rains, additional watering shouldn't be needed.........unless those regular Summer rains are not too regular. If they are lacking water for extended periods, they will often develop powdery mildew. If so, just remove those leaves.
I'm sure it must happen somewhere...........but I've never seen a fully healthy, no bugs, no-rust Hollyhock growing anywhere. They should be in full sun. Maybe you had better luck with the one you purchased this year.
