However, just like any other plant, it can be affected by a few conditions that can impair its health and growth. Here are some common diseases and pests that might affect the plant and ways to manage them.
Diseases
Root rot: This disease is caused by overwatering and poor drainage, leading to the roots' rotting. Symptoms of root rot include yellowing and wilting of leaves and stunted growth. To manage root rot, ensure proper drainage by repotting into well-draining soil or adding more drainage holes. Avoid overwatering and allow the soil to dry out between watering.
Rust: This fungal disease presents with orange or brown pustules on the leaves, and they eventually turn yellow and fall off. To manage rust, remove affected parts of the plant and treat with a fungicide. Ensure proper air circulation and avoid overhead watering.
Pests
Mealy bugs: These are small, white, cotton-like insects that attach themselves to leaves and stems, causing yellowing, wilting and stunted growth. To manage mealy bugs, remove them by hand or wiping them off with a cotton swab dipped in alcohol. Alternatively, neem oil or insecticidal soap can be applied.
Spider mites: These are tiny, light brown or red insects that form webs on the leaves and stems, causing yellowing and wilting. To manage spider mites, spray the plant with a strong blast of water or apply insecticidal soap. Isolate affected plants to avoid spreading the mites.
By practicing good plant hygiene, avoiding overwatering, and regular inspection, you can prevent most diseases and pests from affecting your Crassula swaziensis Schönland var. gurnensis R.Fern. plant.
