Bring back the bees! That was my goal anyway, when I excitedly received free sunflower seeds: Bring Back the Bees Unfortunately 3 out of 4 of my sunflower plants started getting little white dots. Any idea what this may be? Should I throw them out before they spread to my other plants?! The bottom set of leaves also started to turn yellow, on 3 out of 4... Vancouver outdoor balcony with lots of sun!
