Understanding Common Pests of Nandina
Before choosing a pest control method, it’s important to identify the common pests that affect nandina. These include:
- Aphids
- Scale insects
- Spider mites
- Whiteflies
Organic Pest Control Strategies
Organic methods focus on natural solutions that are safe for humans, pets, and beneficial insects. Here are some effective strategies:
Manual Removal
For small infestations, physically removing pests by hand or with a gentle spray of water can be effective. Use gloves to protect your skin and dispose of pests properly.
Insecticidal Soaps
Insecticidal soaps are made from potassium salts of fatty acids and can be sprayed directly onto affected leaves. They work by disrupting cell membranes of pests and are safe for most plants when used as directed.
Neem Oil
Neem oil is a natural pesticide derived from the neem tree. It acts as an antifeedant and disrupts pest reproduction. Apply neem oil during the early morning or late evening to avoid leaf burn.

Healthy plants are less prone to pests. Follow these tips to keep your nandina thriving:
- Ensure proper watering and drainage

- Prune damaged or infested branches promptly

Organic pest control offers a safe and effective way to protect your nandina from common pests. By combining manual removal, natural oils, and preventative care, you can maintain healthy, beautiful plants without the use of harmful chemicals.
