1. Insufficient light.

Because hibiscus is a sun-loving plant, it has high requirements for light, and its leaves will become lush in sunny places, but if you put hibiscus flowers in a poor light environment for a long time, the leaves of hibiscus will turn yellow and wilt, and eventually affect the healthy growth of the plant.

Therefore, if you put the hibiscus in a sunny position and keep it in light for more than 6 hours a day, then the leaves of the hibiscus will reduce the yellowing of the leaves after sufficient photosynthesis, and sufficient light will also effectively enhance the flowering quality of flowers and plants.

2. Improper watering.

Hibiscus likes to grow in a moist and warm environment, the plant needs a relatively large amount of water to grow, if there is a long-term drought and lack of water, then the leaves of the hibiscus will be yellow and dry, but if you water too much for a long time, the roots will rot and cannot absorb nutrients, and there will be yellow and dry up.
