Shrubs Dying

As a plant enthusiast, there's nothing more disheartening than watching your beloved shrubs wither away. Shrubs are a vital part of any garden or landscape, providing structure, beauty, and functionality. However, they can be susceptible to various diseases, pests, and environmental stressors that can lead to their demise. In this article, we'll delve into the common causes of shrub death, prevention strategies, and revival techniques to help you nurse your shrubs back to health.

Common Causes of Shrub Death

Shrubs can die due to a combination of factors, including:

Overwatering: Too much water can cause root rot, leading to shrub death. This is especially true for shrubs planted in heavy clay or poorly draining soil.

Underwatering: On the other hand, shrubs need adequate water to survive. Drought stress can cause shrubs to decline and eventually die.

Pests and Diseases: Pests like aphids, whiteflies, and spider mites can weaken shrubs, making them more susceptible to diseases like root rot, leaf spot, and powdery mildew.
