Shoutout to the master gardener at the Wichita arboretum who caught my black spot before I did
Stopped by the arboretum on Saturday to check out the rose beds and a volunteer pointed at my little potted rose I brought for the plant clinic and said the yellow edges were black spot starting, not sun burn like I figured. She showed me the spots on the underside of two leaves I never would have flipped over. How often do you all check the undersides instead of just the pretty top side?
