Bonsai Tree Pests & Diseases

Pests and Diseases to Watch Out For in Dwarf Jade & Fukien Tea Bonsai

Bonsai trees are living art forms that require meticulous care and attention. Two popular species among bonsai enthusiasts are the Dwarf Jade (Portulacaria afra) and the Fukien Tea (Ehretia microphylla). While both are beautiful and rewarding to cultivate, they are also susceptible to various pests and diseases. Knowing how to identify, prevent, and treat these issues is crucial for maintaining healthy and vibrant bonsai trees.

Pests Affecting Dwarf Jade & Fukien Tea Bonsai

  • Aphids: These small, soft-bodied insects suck sap from the leaves and stems, causing yellowing and distortion. They can be controlled with insecticidal soap or neem oil.
  • Spider Mites: These tiny pests are difficult to see but leave fine webbing on the underside of leaves. They cause leaves to turn yellow and drop. Mitigate spider mites by regularly misting the foliage and using miticides if necessary.
  • Scale Insects: Scale appears as small, round, brown or white bumps on the stems and leaves. They can be scraped off by hand or treated with horticultural oil.
  • Mealybugs: These pests look like tiny cotton balls and congregate on leaf nodes and stems. Remove them manually with a cotton swab dipped in alcohol or use systemic insecticides.

    Diseases in Dwarf Jade & Fukien Tea Bonsai

    • Root Rot: Caused by overwatering and poor drainage, symptoms include yellowing leaves and a mushy, foul-smelling root system. Prevent root rot by ensuring proper watering techniques and well-draining soil.
    • Powdery Mildew: This fungal disease presents as a white, powdery coating on the leaves. Improve air circulation and use fungicides to treat powdery mildew.
    • Leaf Spot: Brown or black spots on the leaves indicate leaf spot disease, often caused by fungal or bacterial infections. Remove affected leaves and apply appropriate fungicides or bactericides.
    • Sooty Mold: This black, sooty fungus grows on the honeydew excreted by pests like aphids and mealybugs. Control the pests by cleaning the leaves with a mild soapy solution.

      Preventive Measures

      • Regular Inspections: Often check your bonsai for signs of pests and diseases.
      • Proper Watering: Avoid overwatering and ensure good drainage.
      • Good Hygiene: Remove fallen leaves and debris from the soil surface.
      • Adequate Air Circulation: Space your bonsai trees to allow for good air flow.
