How to use neem oil for plants. women spraying plants with neem

Neem oil comes directly from the Neem tree's fruit, commonly found in and near India. The Neem tree is often called the miracle tree for its many medicinal benefits from the bark, leaves, and fruit.

Medicinal benefits are not the only thing that Neem trees can provide. Neem oil contains a chemical compound called Azadirachtin.

Azadirachtin is well known for being a natural insecticide and pesticide. When Neem oil is sprayed on plants, it can help combat fungus, bacteria, insects, plant diseases, and weeds. Below are easy-to-follow recipes on how to use neem oil on plants and animals to protect them from bugs.


1. Neem Oil Plant Spray Recipe

Neem oil recipe for Garden spray

Neem oil works as an infective insecticide and pesticide. Protect your plants from fungal disease, bacteria, plant diseases, and leaf-chewing or sucking insects.

You won't have to worry about killing helpful bugs like Leafhoppers, Aphids, Scales, Mites, Caterpillars, Whiteflies, Mites, Thrips, Mealybugs.



Home Garden solution for 32oz (1 Quart) of a 0.5% solution of Neem spray:

  • 1 Tsp (1/2 oz) - cold-pressed Neem oil
  • 1/3 Tsp - Insecticidal soap or Castile soap
  • 1 Quart - Warm water

Industrial solution for 4 gallons of a 1% solution of Neem spray:

  • 13 Tbsp (6.5 oz) - cold-pressed Neem oil
  • 5 Tsp - Insecticidal soap or Castile soap
  • 4 Gallons - of warm water (If you have trouble dissolving the oil, use more soap).


Mixing instructions

Use warm water if possible. When making a large batch, premix the smaller ingredients in a small amount of warm water and then add that to the rest of the water in the larger container.

  1. Mix the warm water with the liquid soap first!
  2. Then, slowly add the oil while stirring vigorously.
  3. Fill the mix into your sprayer. (Or fill the premix into your sprayer, which should already contain the rest of the water. Mix well.)
  4. Keep shaking or otherwise agitating the mix while spraying.
  5. Use the mixture within eight hours.


Spray neem oil as quickly as possible once the spray has been mixed or at least within 8 hours for full effectiveness.

Spray the insecticide solution on all the leaves, especially the undersides of leaves, where garden pests like to hide. Use a 0.5% solution and spray once every two weeks.

This should protect your plants and act as pest control. If an infestation has occurred, spray once a week until the problem disappears.

If it rains, you may need to respray sooner. If you are dealing with a less sensitive insect species, you may need to increase the concentration of the neem spray.


2. Neem Oil Soil Drench Recipe

How to use Neem Soil Drench

Why should you use a soil drench? Systematically give your plants a good soil drench and allow the Azadirachtin in Neem oil to be absorbed into the plant. This allows the neem oil to protect the plant from the inside out. It will also help prevent fungus infections and root rot.


Home Garden solution for 32oz (1 Quart) of a 0.5% solution of neem:

  • 1 Tbsp of cold-pressed Neem oil
  • 1 Tsp of dish castile soap
  • 1 Quart of warm water


We recommend combining neem and castile soap before adding to warm water. Add to the warm water after thoroughly mixing the neem and castile soap. Only do a soil drench once per month. In the case of an infestation, it is best to water weekly until you resolve the problem. 

3. Neem Oil Bug Repellent Recipe

  • 2 Cups - Vinegar
  • 4 Cups - Warm Water
  • 1/4 Cup - Neem oil

The Neem Oil will separate, so this needs to be shaken before and during each use. The Neem Extract will not separate but is not as effective as the oil. The essential garlic oil will increase the effects of the formula, but it works well without also.


Remove the nozzle from an old fly spray bottle or a commercially bought spray bottle. Insert a funnel. Pour 2 cups of vinegar into the bottle using the funnel.

You can use either apple-cider, distilled vinegar, or for healing use Aloe Vera Juice. Add water 4 cups of warm water. Add the 1/4 cup Neem Oil. Replace the nozzle and shake.


4. Neem Oil Head Lice Recipe
