Common Garden Pests and Diseases

Understanding the specific pests and diseases that commonly affect gardens can help you identify and address potential issues more effectively.

Aphids

Aphids are small, soft-bodied insects that typically feed on the sap of plants. They reproduce rapidly and can infest your garden in large numbers. Infested plants may have distorted growth, curled leaves, or sticky honeydew residue. Signs of aphids typically include an accumulation of small insects on the undersides of leaves or near the tips of plants.

Caterpillars

Caterpillars, the larval stage of butterflies and moths, can cause significant damage to garden plants by feeding voraciously on foliage. They often leave behind chewed leaves, irregular holes, or defoliation. Caterpillar larvae can be of varying sizes, colors, and patterns, making identification important for effective control.

Slugs and snails

Slugs and snails are mollusks that can wreak havoc in gardens, feeding on a wide range of plants. They usually emerge at night and leave behind slimy trails. Signs of slugs and snails include irregular holes or damage to leaves and the silvery traces they leave on garden surfaces.

Fungal diseases

Fungal diseases like powdery mildew, downy mildew, or leaf spots can affect a variety of plants in your garden. These diseases often appear as discolored patches, fuzzy or powdery growth, or spots on leaves, stems, or flowers. Poor air circulation and high humidity levels can contribute to the development of fungal diseases.

Bacterial diseases

Bacterial diseases, such as bacterial blight or bacterial spot, can cause damage to a wide range of plants. Symptoms include spots, lesions, wilting, or rotting of plant tissues. These diseases can be spread through contaminated plant material, tools, or splashing water.

Dealing with Aphids

Aphids are among the most common garden pests, but they can be effectively managed with the right approach.
