Garden Pest Control Guide: Identify Pests & Choose the Right Treatment

Identify common plant pests and diseases from symptoms and understand the most suitable organic treatment approach.

Pests and diseases can affect plant leaves, stems, roots, and overall growth. Early identification helps prevent serious damage and improves plant health.

Identify Plant Problems by Symptoms

  • Sticky leaves / black coating → Sucking insects
  • Holes in leaves → Chewing insects
  • Leaf tunnels → Leaf miners
  • Wilting or weak growth → Root or soil issues
  • White powder / black spots → Fungal disease

Treatment may involve bio-pesticides or organic fungicides.
