With the increasing emphasis on indoor plant decoration, succulents are popular for their unique shapes and low maintenance. It is inevitable to encounter pests and diseases during the care of succulents. Understanding the common pests and diseases in succulents and their control methods is crucial for ensuring the healthy growth of these plants. This article will provide a detailed analysis of the common pests and diseases in succulents.
Overview of Pests and Diseases in SucculentsPests and diseases in succulents refer to various biological or non-biological factors that affect the growth and aesthetics of succulents. Biological factors mainly include pathogens, viruses, and pests, while non-biological factors include environment, soil, and water.
Common Pests and Diseases and Their Symptoms in Succulents1. Diseases
(1) Black Rot: Black rot is a disease caused by fungi, manifested by blackened and rotting leaves, and can lead to the death of the entire plant in severe cases.

(3) Chemical Control: When necessary, use low-toxicity and low-residue pesticides for control.
Understanding the pests and diseases in succulents and their control methods helps us better care for these plants and ensure their healthy growth. During maintenance, we should pay attention to the growth status of the plants, promptly detect pest and disease problems, and take corresponding control measures. Maintaining good ventilation, reasonable fertilization, and timely cleaning are also important means of preventing pests and diseases.
