Black pepper protects plants by killing or repelling various pests. A study by a Doctoral student showed that pepper was effective on insects. It works within 24 hours and is even more effective than some synthetic pesticides. Pepper has many advantages over most synthetic insecticides in that it does not contaminate groundwater, harm human or other animals and insects do not develop resistance to it.
Promotes Plant Health
Plants face a wide variety of ailments from bacteria. Black pepper is a natural antibacterial agent, working against a number of fungus and bacterial infections. Mix the pepper into the soil of the plant, and bacteria will have more difficulty growing both in the soil and up into the plant. The plant will absorb the black pepper compounds, providing further protection. Use it on plants that are fighting bacterial infections and as a preventative measure.
Protection Against Pets If you are having difficulty with your dog, cat, or other animal and your plants, black pepper can provide a safe, simple and inexpensive option. Many animals do not like the taste or smell of black pepper. If you spray the leaves with a black pepper solution or sprinkle it on, animals may be more likely to stay away from the plant. You may only have to do it a few times before they learn, and then you can discontinue the practice. This can also work on outside plants as risk from wild animals.
Protection Against Ants Black pepper protects plants by keeping away ants. Ants harm plants by transmitting diseases like botrytis blight and fire blights. Ants also protect the much more damaging aphids, mealybugs, and scale. Black pepper repels ants because it contains the ant repellent capsaicin. Sprinkle some black pepper on the plants. Alternatively, mix half of a teaspoon of ground pepper in warm water and place it into a spray bottle. Spray your plants with the solution. You can also add the black pepper to the soil of the plant.
