Yes, white oil can be used on herbs, as it is generally safe for use on all edible plants.
However, there are a few crucial points to keep in mind:
-
Safety: White oil is considered safe because it's a highly refined petroleum product that suffocates insects and mites. It's different from using harsher chemicals.
-
Washing: Always wash herbs thoroughly after applying white oil and before consuming them. This removes any residue.
-
Application: Apply white oil according to the product instructions. Over-application can harm the plant. Avoid applying it in direct sunlight or during very hot weather to prevent leaf burn.
-
Timing: Ideally, apply white oil in the early morning or late evening to minimize stress on the herbs.
-
Target Pests: White oil is most effective against soft-bodied pests like aphids, mites, and scale. Consider whether your herbs are infested with these types of pests.
-
Alternatives: Before using white oil, consider other pest control methods such as insecticidal soap, neem oil, or simply washing the herbs with a strong stream of water. Sometimes a simpler solution is best.
-
Specific Herbs: While generally safe, it's always a good idea to test a small area of a particular herb before treating the entire plant, especially if it's a sensitive variety.
