What should I do if the flowers grow tired?

White greasy bugs on flowers can be soaked in plant ash water medium. Specifically, 0.5 kg of plant ash is mixed with 2.5 kg of water, soaked for one day and night, then put into a watering can and sprayed on plants. You can also wipe it with vinegar. Dip a cotton ball in vinegar, and then gently wipe it on the pest site to kill it. In addition, we should pay attention to management methods. Usually flowers must be ventilated and basked in the sun, which can reduce pests.
