Fresh, fragrant, and fast-growing, basil is a favorite for home gardeners. But even this hardy herb isn't immune to pests and plant issues. If your basil is looking sad, don’t panic—most problems are easy to spot and fix.

Here’s a quick guide to the most common basil pests and problems, plus proven solutions to keep your plants healthy and thriving.

🐛 1. Aphids

Symptoms: Sticky leaves, curled tips, clusters of tiny green, black, or white bugs on stems.
Fix: Spray leaves with a mild soapy water solution or neem oil. Introduce ladybugs if growing outdoors.

🐜 2. Spider Mites

Symptoms: Fine webbing under leaves, tiny red or yellow dots, dusty appearance.
Fix: Increase humidity (mites hate it), rinse plants thoroughly, then spray with neem oil or insecticidal soap.

🐞 3. Whiteflies

Symptoms: Small white insects that fly up when plant is disturbed, yellowing leaves.
Fix: Use yellow sticky traps, or spray with neem oil every few days. Isolate infested plants.

🐌 4. Slugs and Snails (if grown outside)

Symptoms: Large irregular holes in leaves, slimy trails.
Fix: Handpick at night, use beer traps, or sprinkle crushed eggshells around the base of the plant.

🌱 5. Leaf Spot / Fungal Infections

Symptoms: Brown or black spots on leaves, fuzzy mold, leaves dropping.
Fix: Improve air circulation, avoid watering leaves, remove affected foliage. Use an organic fungicide if needed.

💧 6. Overwatering / Root Rot

Symptoms: Yellow, wilting leaves; soft stems; sour smell from soil.
Fix: Let soil dry between waterings. Repot in well-draining soil and a container with drainage holes.

☀️ 7. Sunburn / Leaf Scorch

Symptoms: Bleached or dry brown patches on leaves.
Fix: Basil needs sun, but avoid intense midday sun behind glass. Filter direct light or move to partial shade.

🧪 Pro Tip: Neem Oil for Basil

Neem oil is a natural pesticide that’s safe for edible plants. Mix 1 tsp of neem oil + 1 tsp mild dish soap in 1 quart of water. Spray early morning or late afternoon every few days when pests appear.
