How to Fix Blackened Leaves On a Plant

What Causes Blackened Leaves on a Plant?

Blackened leaves on a plant can be a worrying sight, especially if you're new to indoor gardening. It's essential to identify the root cause of the problem to take corrective action and prevent further damage. Blackened leaves can be caused by a variety of factors, including:

Overwatering: Too much water can cause the roots to rot, leading to blackened leaves. This is especially common in plants that prefer well-draining soil, such as succulents and cacti.

Underwatering: On the other hand, if the soil is too dry for an extended period, the leaves may also turn black. This is often seen in plants that prefer moist soil, such as ferns and peace lilies.

Diseases: Fungal diseases like root rot, leaf spot, and crown rot can cause blackened leaves. These diseases are often caused by overwatering, poor air circulation, or contaminated soil.

Pests: Infestations by pests like spider mites, mealybugs, and scale can cause blackened leaves. These pests suck the sap from the leaves, causing them to turn black and wither.
