Crassula ovata 'Gollum', also known as the Gollum Jade, is a succulent plant with thick leaves and beautiful shape, widely loved for its appearance. However, Crassula ovata 'Gollum' may suffer from some pest infestations during its growth, which not only affect the ornamental value of the plant but may also threaten its health. This article will introduce the common pests of Crassula ovata 'Gollum', identification methods, and control measures.
Aphids: Aphids are common pests of succulent plants, usually gathering on the tender leaves and stems, sucking the sap of the plant. Aphid infestation can cause leaf deformation and discoloration, and may even trigger plant diseases in severe cases. The method to identify aphids is to observe whether there are dense insects and sticky honeydew on the plant leaves.
Spider mites: Spider mites are tiny pests that mainly absorb the moisture from the plant leaves, causing yellow spots or drying of the leaves. Spider mite infestation is more severe in dry environments. The method to identify spider mites is to observe whether there are tiny red insects on the back of the leaves and whether there is web-like silk.
Scale insects: Scale insects are common pests of succulent plants, attaching to the leaves and stems of the plant, sucking the sap. Scale insect infestation can cause slow growth and loss of luster in the leaves. The method to identify scale insects is to observe whether there are white spots or shell-like objects on the surface of the plant.
Root mealybugs: Root mealybugs are pests that live in the soil, sucking the sap from the plant roots, causing poor growth. The method to identify root mealybugs is to observe whether there are white insects on the plant roots and whether the soil becomes dry.
In response to these pests, the following control measures can be taken:
Physical control: Regularly inspect the plants, and once pests are found, remove them by hand or with a soft brush. For root mealybugs, replace part of the soil to reduce the number of pests.
Biological control: Use natural enemies to control the number of pests, such as ladybugs, hoverflies, etc. This method is environmentally friendly but may be slower in effect.
Chemical control: Use insecticides to control pests. When choosing insecticides, select those safe for succulent plants and use them according to the instructions. Be careful not to overuse them to avoid harming the plants.
Environmental control: Keep the plant growing environment clean and well-ventilated, avoid overwatering to reduce the breeding of pests. Also, adjust the light and temperature of the plant appropriately to enhance its resistance to pests.
