  • Scale Insects: Hard or soft-bodied insects that attach to stems and leaves.
  • Whiteflies: Small, white-winged insects that feed on the underside of leaves.

Preventive measures and treatments:

  • Regularly inspect leaves and stems.
  • Use insecticidal soaps or neem oil sprays.
  • Maintain good air circulation and avoid overwatering.

Common diseases:

  • Root Rot (Phytophthora): Caused by waterlogged soil; prevent by ensuring drainage.
  • Citrus Canker: Bacterial disease causing lesions on leaves and fruit; remove infected parts and sanitize tools.
  • Sooty Mold: A fungal growth associated with sap-feeding insects; control pests to reduce mold.
