1. Zinnia Watering Care

Common Zinnia's excessive growth may be caused by too much watering. If common zinnia is watered too much, it will lead to root water, which will affect the respiration of Common Zinnia's root system. Finally, it will cause Common Zinnia's growth, and even water rot the roots, so that the branches and leaves gradually turn yellow, so that Common Zinnia wither and die.
