Coral Bells, known scientifically as Heuchera, are popular perennials admired for their vibrant foliage and delicate flowers. However, like many garden plants, they can fall victim to pests such as aphids, spider mites, and whiteflies. Gardeners seeking eco-friendly and safe pest control methods often turn to natural solutions like neem oil.
What is Neem Oil?
Neem oil is a natural extract derived from the seeds of the neem tree (Azadirachta indica), native to India and Southeast Asia. It has been used for centuries in traditional medicine and agriculture for its pesticidal and medicinal properties. Neem oil contains compounds such as azadirachtin, which disrupts the life cycle of many pests.

Applying neem oil to coral bells is a straightforward process. Follow these steps to ensure effective pest control:
- Mix neem oil with water according to the manufacturer’s instructions, typically 1-2 teaspoons per gallon.
- Add a few drops of liquid soap or a horticultural oil to help the mixture adhere to the leaves.
- Use a spray bottle or garden sprayer to thoroughly coat the foliage, undersides of leaves, and stems.
- Apply early in the morning or late in the afternoon to avoid leaf burn and maximize effectiveness.
- Repeat every 7-14 days as needed, especially during peak pest activity.
Precautions and Tips
While neem oil is generally safe, it’s important to follow some precautions:
