How can flowers be green?

Diligent fertilization: fertilize flowers regularly and apply foliar fertilizer appropriately to promote their growth. Regular insecticidal: when it is found that flowers are infested by pests, immediate measures should be taken. Generally, diluted soap, essential oil solution, washing powder solution and other liquids can be sprayed, which can kill insects effectively. Increase air humidity: place a humidifier next to the flowers, or often spray water on the flowers to keep their leaves moist.
