Yes, you certainly can! It’s a straightforward formula that doesn’t necessitate much effort. What’s great about utilizing neem oil is that your homemade spray will almost certainly be more effective than a store-bought one.
This is due to the fact that you are in charge of picking high-quality, pure neem oil. You’ll be able to get a lot of azadirachtin in your solution if you do it this way. Pests are killed by this active chemical. When opposed to a store-bought spray, you can add extra by combining the materials yourself.
Look for neem oil that is “raw” or “crude,” meaning it is 100 percent pure and cold-pressed. Because heat kills azadirachtin, it must be cold-pressed. This indicates that heat-derived oils have insufficient amounts of this active ingredient.
Another benefit of purchasing pure organic neem oil is that contamination is avoided.
Processed neem oil may contain solvents or chemicals as a result of the manufacturing process. When these come into contact with your plants, they could be dangerous.
Don’t be surprised by the last one; the bargain is fairly straightforward. Because oil and water don’t mix, you’ll need to come up with a means to get around this while making the spray. Mild liquid soap can be used as an emulsifier to help the water and neem oil blend together.

- Once every 24 weeks, use. Early in the morning or late in the afternoon is the best time to use it. Neem Oil should not be used in direct sunlight. It has the potential to induce leaf burn. Always test plants for susceptibility to sprays on a small area first.
- Spray a generous amount of the diluted solution on all leaf surfaces, including the undersides.
- At lower temperatures, neem oil may solidify.
- Temperatures should be kept between 65 and 95 degrees Fahrenheit.

Neem oil is a concentrated plant oil derived mostly from the seeds of the neem tree, which is native to India. As an organic pest management, the oil is diluted and blended with water before being sprayed to plant foliage.

Neem has therapeutic medical effects and is often used in personal care products for individuals in addition to being a natural, mild pesticide.
“Many components make up neem oil, including Omega 3, 6, and 9 fatty acids. As a pesticide, azadirachtin is the most active component. It works as an insect repellent and limits the capacity of insects to feed. It also disrupts insect hormone systems, making it more difficult for insects to reproduce and deposit eggs. Azadirachtin can also resist nematodes and inhibit their feeding.”
“Neem oil” is available as 100 percent pure neem oil, a concentrated neem oil with other additives, or a pre-mixed, ready-to-use spray. Personally, we like to use 100% pure ingredients and make our own concoctions. It is both the most cost-effective and the safest option. Furthermore, a pre-mixed neem oil product line was recently discovered to be tainted with a number of synthetic, non-organic pesticides not listed on the label, including Malathion, Chlorpyrifos, and Permethrin!

Is neem oil harmful to plants?
Neem is a pesticide that is produced naturally from the seeds of the neem tree (Azadirachta indica). Tropical woods in Burma, India, and Sri Lanka are home to neem trees. For hundreds of years, the tree’s natural range has been employed as a botanical insecticide. Neem products have become fairly easy to purchase at most garden centers, thanks to a growing interest in organic and less-toxic pesticide solutions. Many gardeners may now reach for it first when they have a pest problem. If you understand how neem works and simply apply items according to label instructions, it can be a valuable component in an integrated pest management strategy.
One of two active components is commonly found in neem products. Azadirachtin, a chemical obtained from neem seed oil, is primarily responsible for insect killing and repellence. The residual material is known as clarified hydrophobic neem oil after the Azadirachtin is extracted from neem oil. Azadiractin is exclusively found in commercial insecticides and is used to alter the hormones that control insect growth and reproduction. The active ingredient in ready-to-use neem oil sprays that may be purchased at a garden center is clarified hydrophobic neem oil.
Neem oil can be used to treat a variety of insect and fungal diseases. It suffocates insects by coating their bodies in oil, which clogs their breathing holes. It works best on insects that are still juvenile. Adult insects aren’t usually killed when they reach maturity, so they can continue to feed and reproduce. As a result, timing a neem oil spray requires constant monitoring of insect lifecycles.
Even if you apply neem to immature-stage insects, don’t expect to see results right away. It takes time to work, and it may be necessary to reapply to totally control bug populations. Pests handled by neem pesticide products include aphids, beetle larvae, caterpillars, lacebugs, leaf hoppers, leafminers, mealy bugs, thrips, and whiteflies. Make sure to identify insects precisely, and only use neem oil if the pest is indicated on the label. Both beneficial and pest insects can be harmed by neem.
Powdery mildew is one of the fungal diseases that can be treated with neem oil. It acts by preventing fungus spores from germinating and penetrating leaf tissue. Although neem won’t “cure” a plant sick with a fungal disease, it can assist limit the illness’s spread to good tissue.
Products containing neem oil are frequently labeled for a variety of crops, including herbs, vegetables, fruits, nuts, and decorative plants. Neem oil can harm plants by burning their foliage, regardless of the type of plant being treated. Use with caution on newly transplanted or stressed plants.
