Natural Pesticide Ingredients 

The natural pesticide for plants can be made from simple homemade ingredients. Let’s understand their function in our natural homemade pesticide. 

  • Neem oil: Acts as a potent pesticide, disrupting pests’ life cycles therefore reducing their population.
  • Baking soda: Controls fungal diseases by creating an inhospitable environment for fungal growth on plants.
  • Essential oils (citronella, peppermint, eucalyptus): Repel insects with their strong scents, making plants less attractive to pests.
  • Garlic and hot peppers: Serve as natural deterrents, repelling a wide range of pests from plants.
  • Apple cider vinegar: Attracts and traps fruit flies, preventing them from infesting fruits and vegetables.
  • Dish soap: Enhances the effectiveness of pesticides by breaking down the insects’ protective coatings and suffocating them.

6. Homemade Fertilizer Spray for Plant Health

In addition to pest control, homemade plant sprays can also improve plant health. A homemade fertiliser spray can provide essential nutrients to support plant growth and vigour. Follow these steps to create your own fertiliser spray for plants.

Ingredients:

  • Water
  • Organic materials (e.g., kitchen scraps, weeds, grass clippings)
  • Bucket or container with a lid
  • Strainer or cheesecloth

Instructions:

  1. Collect organic materials such as kitchen scraps (vegetable peels, coffee grounds, crushed eggshells), weeds, and grass clippings. Avoid using meat, dairy, or oily items.
  2. Fill a bucket or container with water and add the organic materials. The ratio should be approximately 1 part organic materials to 3 parts water.
  3. Stir the mixture well to ensure the organic materials are fully immersed in the water.
  4. Cover the bucket or container with a lid and let the mixture sit for about 3-4 weeks. This allows the organic materials to decompose and release nutrients into the water.
  5. After the fermentation period, uncover the container and strain the liquid using a strainer or cheesecloth to remove any solid particles. The resulting liquid is your homemade fertiliser.
  6. Dilute the fertiliser with water before use. The exact dilution ratio will depend on the strength of your homemade fertiliser and also the specific needs of your plants. Start with a 1:10 ratio (1 part fertiliser to 10 parts water) and adjust as necessary.
