Potted plants bring life to your home. Pests can harm them. Use organic methods to keep plants healthy. These ways avoid harsh chemicals. They work well for indoor and outdoor pots.
Common Pests in Potted Plants
Many bugs target potted plants. Spot them early to act fast.
- Aphids: Small green or black bugs that suck sap from leaves.
- Spider mites: Tiny spiders that cause yellow spots and webs.
- Mealybugs: White fluffy pests that hide in leaf joints.
- Fungus gnats: Black flies that lay eggs in wet soil.

These pests weaken plants. They spread fast in pots.
