Is there something wrong with the way I care for sunflowers, so that those that are on the edge of almost all fall off.🥺 Anyone can explain this to me, maybe I still have to learn a lot about sunflowers, so that they can continue to bloom and be big so that they can produce good seeds later.🥺🥺 Please anyone who knows about this, tell me, I am really sad when I saw this, it didn't happen before, was it because of the rain last night.🥺
