How to Make a Neem Oil Mixture for Plants

To make neem oil mixture for plants, you should begin by preparing the materials, tools, and oil. After this, you should mix the oil with some liquid soap, and then add the right amount of water, blend the mixture, transfer to a spray bottle, and start spraying.

Unlock the potential of neem oil, derived from the seeds of the native Indian and Southeast Asian neem tree. With a rich history in traditional medicine and natural pest management tool as a foliar spray, this potent oil offers you a unique opportunity to harness its benefits!

1. Prepare the Materials

You’ll need three ingredients for this: pure neem, liquid dish soap, and water. Neem oil contains a variety of beneficial compounds, including azadirachtin, which acts as a repellent and insect growth regulator for garden pests. When purchasing the oil, choose a cold-pressed or unrefined variety, as it retains more natural properties.Preparing Materials for Neem Oil

Liquid dish soap is added to the neem oil spray as an emulsifier. It helps to break down the oil and mix it evenly with water. Look for a mild, natural liquid dish soap without harsh chemicals or fragrances. Avoid using dish soaps that contain bleach, antibacterial agents, or strong detergents, as they may harm your plants.

Water is a crucial component of the oil spray, as it dilutes the oil and allows for easy application. It’s important to use clean, preferably filtered water to avoid impurities that could harm your plants, and this is also necessary so that you would have the right concentration for the right plants that you may be tackling.

Tap water is generally suitable unless it’s heavily chlorinated or contains high levels of minerals. If you’re concerned about the water quality, you can let tap water sit uncovered for a complete day before using it to allow any chlorine to dissipate.

2. Prepare the Tools

You will now need a measuring cup or spoon, a spray bottle, a mixing container, and your preferred stirring utensil. To ensure precise measurements, equip yourself with a measuring cup or spoon for the neem oil and liquid dish soap. This helps guarantee the perfect dilution ratio, preventing any excess or insufficient use of ingredients.

Moreover, you should also select a bottle that suits your desired quantity for the neem mixture spray. A smaller bottle suffices for a modest batch, while a gallon-sized bottle or multiple smaller ones are preferable for larger amounts. Opt for a bottle with a nozzle that produces a fine mist spray pattern, promoting optimal coverage on plant surfaces.

Choose a mixing container capable of comfortably accommodating your oil spray volume and how it would transfer the solution to your plants. Larger quantities call for a bowl or bucket, while a sizable mixing bowl or pitcher works well for smaller batches. Prioritize cleanliness, ensuring the container is free from residue or contaminants that may impact the spray mixture.

Use a stirring utensil to achieve a thorough blend of neem oil, liquid dish soap, and water. A spoon or whisk will suffice for this purpose. Prioritize cleanliness using a clean utensil to prevent any undesired contaminants from infiltrating the mixture.

3. Prepare the Neem Oil

For this step, gather your neem oil, a measuring cup or spoon, and optionally, a funnel. Neem oil allows you to adjust its concentration based on the severity of infestations you’re dealing with. In such a case, you can seek out cold-pressed neem oil, extracted from neem tree seeds using a heat-free, chemical-free process.

This method ensures a higher concentration of its naturally beneficial compounds as a neem oil insecticide. When acquiring your oil, trust reputable sources like garden centers, nurseries, or established online platforms, to get the right type of oil. Use a measuring cup or even the right spoons to measure the oil accurately.

Pour the appropriate amount into a mixing container based on your desired concentration. For instance, if you’re preparing a gallon of oil spray with an attention of one tablespoon per gallon, pour a single tablespoon of the oil into the mixing container.

Even though you can consider neem oil safe, it tends to solidify in colder temperatures; consider warming it slightly to facilitate measuring and mixing. Place the oil container in a bowl of warm water for a few minutes to liquefy the oil.

Avoid direct heat sources like stovetops or microwaves, as excessive heat may compromise the oil’s beneficial properties. In short, you must also try to go for the precise pouring to prevent spills, and this is the right reason why a funnel can be helpful if you find it challenging to pour neem oil accurately into a measuring spoon or cup.

4. Add the Liquid Soap

Look for a mild and environmentally friendly liquid dish soap, free from artificial scents or harsh chemicals. It is prudent to avoid antibacterial dish soaps, as they could potentially harm the beneficial insects and microorganisms thriving in your garden.

When concocting your neem solutions spray blend, consider the batch size and carefully measure the appropriate quantity of liquid dish soap. As a general guideline, incorporate approximately half to one teaspoon of dish soap for almost every gallon of water.

Once you have accurately measured the necessary amount of dish soap, pour it into the mixing container alongside the neem oil. On this notion, you should also remember that soap is needed so that the oil will emulsify them properly.

On the other hand, add dish soap after the neem oil to prevent excessive foaming. The foam will settle itself and will not actively harm beneficial insects if the liquid soap has mild ingredients.

5. Mix the Neem Oil and Liquid Soap

To ensure optimal emulsification and prevent any detectable oil separation or floating, combining neem oil and dish soap is imperative before introducing water. Select a clean container of adequate size, such as a residue-free bowl or bucket, to accommodate the desired quantity of neem mixture spray without contamination.Mixing Neem Oil with Liquid Soap

You can use a measuring cup or spoon to determine the appropriate amount of oil based on the desired spray concentration and quantity for precise measurement. Typically, tablespoons or teaspoons serve as suitable units for neem oil measurement. Consult the instructions on the bottle for the recommended dilution ratio, and to be precise.

Pour the measured neem oil into the mixing container with care to avoid spills or splashes. Now, it’s time to add the liquid dish soap. Opt for a mild and natural variant without added fragrances or harsh chemicals.

The dish soap acts as a proficient emulsifier, facilitating the seamless oil blending with water and ensuring uniform plant distribution. Measure the necessary amount of dish soap based on the recommended ratio, typically ranging from half to one teaspoon per gallon of water.

Using a preferred stirring utensil, like a spoon or whisk, thoroughly blend the neem oil and dish soap. You can also use a circular stirring motion to achieve a comprehensive mixture, and it would mix in pretty well. Keep stirring until a consistent blend is attained, free from any visible signs of separation.

6. Add Water

The water quantity depends on your bottle’s size or desired spray volume. For a gallon-sized bottle, fill it up to the gallon mark, and for this, you must also adjust the water amount accordingly if using a smaller bottle. Leave some headspace for shaking and mixing convenience.Neem Oil Concentration

Opt for room temperature or slightly warm water when blending with neem oil and dish soap to achieve optimal results. Cold water may cause oil solidification or hinder proper mixing. When pouring water into the mixing container, gradual addition is advised over a single pour.

This gradual approach promotes thorough mixing, ensuring the oil and dish soap emulsify effectively. Stirring continuously while slowly pouring prevents ingredient separation or clumping. As you add water, keep going and stirring so that you ensure an even distribution of neem oil and dish soap throughout.

7. Blend the Mixture

For optimal blending, using a spoon or whisk as your stirring tool is advisable. Ensure its cleanliness before starting. Begin stirring the mixture gently and consistently, employing circular movements to incorporate all the ingredients.Neem Oil

Also, scrape the sides and the bottom of the container to ensure thorough mixing. Continue stirring for a few minutes or until you observe a harmonious fusion of neem oil, dish soap, and water, as you see it properly diluted and one color of a solution. This stage requires patience and thoroughness to achieve a homogeneous blend.

Neem oil, being insoluble in water, requires the addition of dish soap as an emulsifying agent. This helps break down the oil into tiny droplets and evenly disperse them within the water. Vigorous stirring facilitates the emulsification process, ensuring the uniform distribution of the oil throughout the spray.

While stirring, you may notice a slight opaqueness or cloudiness in the mixture, indicating the initial combination of neem oil and water. Moreover, you should still continue stirring until the mixture achieves a well-mixed and consistent appearance throughout.

During the stirring process, the dish soap may generate surface foam, which is a normal occurrence and does not affect the effectiveness of the spray. If you wish to minimize foam formation, stir gently or allow the mixture to rest briefly before transferring it to the bottle. Either way, mix well to let the neem oil work its magic.

8. Transfer to Sprayer Bottle

It’s best to choose a clean and well-maintained spray bottle to maintain optimal functionality. Look for one with an adjustable nozzle, allowing you to control the spray pattern, whether you prefer a fine mist or a concentrated stream. When dealing with bottles that have narrow openings, using a funnel can make pouring the oil mixture easier and spill-free.

To ensure a stable pouring surface, securely position the funnel at the bottle’s opening. Carefully pour the oil mixture into the bottle, using a steady and measured approach to minimize spills. When utilizing a funnel, ensure the mix flows smoothly through it, enabling a seamless transfer into the bottle.

Start by filling the bottle to about one-third to one-half of its capacity. Leaving some space at the top allows for proper mixing of the ingredients by allowing the mixture to be shaken before use. After pouring the oil mixture, firmly attach the cap or nozzle to the bottle, ensuring a tight seal to prevent any leakage during storage and application.

Before the neem oil application to your plants, give the bottle a good shake. This essential step thoroughly blends the neem oil, soap, and water, and so you may shake the bottle vigorously for approximately 20 to 30 seconds to achieve a well-mixed solution. And there you have it, your very own organic oil mixture for plant diseases and pest control.

9. Start Spraying

Neem oil spray can be used on edible plants. However, following the instructions and recommended waiting periods mentioned on the neem oil product label is important. This ensures that the residue on the plants has time to break down. Consequently, applying neem solutions this way makes them safe for consumption.

Mixing the neem oil with other pesticides or fungicides is not recommended unless explicitly mentioned on the product labels. Mixing different chemicals can lead to unpredictable reactions and potentially harm your plants.

It’s best to use neem oil as a standalone treatment when in doubt. Alternatively, you can consult a gardening expert for specific guidance when applying neem oil with other products.


Knowing how to mix your own neem oil solution is actually winning most of the battle against fungal diseases, so here’s a quick recap for you to make the odds even higher:

  • The recommended ratio for mixing neem oil is one to two tablespoons per gallon of water.
  • Use a mild liquid dish soap as an emulsifier when mixing neem oil to help it mix with water.
  • Apply the neem solutions spray immediately after preparation for maximum effectiveness.
