After the hot summer, the natural sunflower, which is in a semi-dormant state, begins to recover gradually, growing leaves and blossoming again, adding color to the golden autumn. However, it is inevitable that the geranium, which has just passed through the hot summer, is undergrown because of its old roots and leaves. The newly extracted leaves are small and dark green, the petioles and inflorescence stalks are short, the bouquet is small, and the whole plant shape is clustered, which reduces the ornamental value. The treatment of geranium with gibberellin can effectively promote the blooming of leaves and flowers and improve the ornamental value. The method is that when the inflorescence stalk of the first batch of flowers changes from curved to erect after the growth of the geranium plant is restored.
