What are the methods for controlling aphids on flowers in spring and summer?
How do you control aphids on flowers in spring and summer? Please explain the methods. Many aphids, every year in the spring and summer period, like to gather densely on the young leaves, young shoots, young stems, buds, flower buds and corollas of Chinese roses, chrysanthemums, hibiscus and so on, causing damage. They use piercing-sucking mouthparts to absorb large amounts of sap from plant tissues, causing a lack of nutrients in the flowers, making the roots, stems, leaves, flowers and flower buds of the affected parts grow slowly or stop growing, and in severe cases causing the whole plant to wither or die.
