Does Cayenne Pepper Help Plants?
Cayenne pepper is non-toxic to your plants. It’s mostly beneficial as a repellent to keep animals and some insects away from your plants.
The main ingredient in cayenne peppers is capsaicin that irritates the skin and taste buds of animals. Furry critters, like squirrels, rabbits, and deer don’t appreciate the spicy hot flavor of cayenne peppers, so they’re less apt to dine on your plants after taking a taste.
It is also found to be toxic to some insects like spider mites and lace bugs as it damages their nervous system.
How Do I Use Cayenne Peppers on Plants?
You can use the cayenne pepper in different ways on the plants depending on what you need. Keep in mind that regardless of the method you choose, you’ll have to reapply after it rains.
Make a Cayenne Pepper Spray
The best way to use cayenne pepper to deter animals is to make a spray and apply it to your plants.
To make the spray you can either use fresh cayenne peppers from your garden or store. Or you can use the pepper flakes you may have bought. I’ve written a post that will help you grow some hot and spicy peppers in your garden.
- Take 1 gallon of water and 2 tablespoons of the chopped up cayenne pepper or flakes in a cooking pan.
- Heat the mixture on a high-medium heat till it starts boiling. Then lower the heat to medium and let it simmer for a while.
- Make sure to keep your face away from the steam that may arise during this cooking process. Otherwise, you can get some serious irritation on your face, nose, and throat.
- Once the mixture has cooked for about 15 minutes, you need to close the heat. Let it stay in the pan for 24 hours.
- This will give the mixture the most potency when used as a spray to deter pests and animals.
- After 24 hours, you can use a sieve to remove the pepper pieces or flakes from the mixture. You just need the liquid that has the full-strength of the cayenne pepper.
- Mix 2 teaspoons of biodegradable vegetable oil into this mixture. This oil will help the cayenne pepper mixture to stick to the plants without harming them.
- You can fill the strained mixture in a spray bottle for use in your garden. The cayenne pepper spray will last you 2-3 months before it loses its potency.
Before using this spray, put it on a few leaves and let it stay for a few hours. If the leaves don’t suffer from any negative effects, you can continue using the spray on the entire plant.
To use the cayenne spray you created, you need to spray it on all the parts of the plants that are been attacked by pests and animals.
It’s best to apply this spray in the morning after you have watered the plants. You don’t want to apply it in the afternoon as the heat from the sun will bake this mixture and harm the leaves.
The effect of the spray will last you a few days and then you need to reapply. If it rains in your garden, the spray will get washed away and you need to reapply immediately.
If you’re spraying the cayenne pepper on your vegetable plants, make sure to wash the leaves or vegetables well after the harvest. Otherwise, you’ll get an unwanted spicy flavor from the vegetables.
Create a Cayenne Pepper Barrier
If you want to deter insects from crawling up to your plant, a cayenne pepper barrier is something to consider.
You can sprinkle the cayenne pepper powder around the edges of your garden, individual plants, or flowerpots.
This keeps the insects away because the cayenne pepper is toxic or abrasive to some of them.
Tip: you can use cayenne pepper with diatomaceous earth for an effective organic insecticide.
Burn Cayenne Pepper to Create Smoke
Cayenne pepper acts as an irritant when it’s burnt. You can use this property of the cayenne pepper to remove pests from your garden.
You can burn one ounce of powdered pepper near the plants with pest problems. This will either kill the pests or drive them away from the plants.
Make sure to keep children and pets away from the garden when you’re using this method. It can really irritate their eyes and nose.
Is Cayenne Pepper Toxic to Dogs?
Cayenne pepper is not toxic to dogs and other animals like cats, rabbits, and squirrels. It will irritate their nose, throat, and skin if they come in contact with the pepper.
That’s why a cayenne pepper spray or powder can be used to deter such animals from damaging the plants in your garden.
You can find other methods to keep your pets away from the garden. I’ve written a post that shows simple and easy methods you can use for this purpose.
Will Cayenne Pepper Hurt Earthworms?
Cayenne pepper can hurt earthworms because it burns their skin and membranes just like in humans.
You can use the cayenne pepper powder or spray to get rid of insects from the plants. And to prevent insects from crawling into the plants.
What Can I Use in Place of Cayenne Pepper?
Cayenne peppers are a wonderful, natural option for repelling insects and animals in your garden. It’s especially convenient if you can grow your own cayenne pepper plants.
Using cayenne peppers may not work for every gardener, especially if you have pets or young children. Using cayenne pepper liberally in a garden may be problematic for young children and dogs because it can be an irritant.
Children can get the cayenne pepper on their skin or in their eyes and have a reaction. Dogs can get sick if they get too close to the cayenne pepper.
Fortunately, there are plenty of natural alternatives that you can make in the comfort of your home. If using cayenne pepper isn’t right for your garden, try one of these alternatives to keep those pests at bay.
- Mix a little vegetable oil with mild soap to create an insecticide that’s safe for plants but deadly to aphids, mites, and more.
- Neem oil disrupts many types of bugs and fights off fungal infections, including powdery mildew. Mix a few teaspoons of neem oil and a teaspoon of mild liquid soap into a quart of water to spray on affected leaves.
- Diatomaceous earth (mentioned above) is harvested from the earth and effective against insects because it is abrasive and causes them to dehydrate. Simply sprinkle it around affected areas. Learn how you can use diatomaceous earth to get rid of pests from your plants.
