Neem oil, the organic wonder treatment for cannabis
Neem oil is impressive stuff, and in this article, we’ll teach you how to mix the perfect solution for almost all cannabis pest problems. Neem oil won’t completely get rid of your pests, and you shouldn’t believe anyone who tells you their solution will. What neem oil will do is help you keep the pest population’s impact to a minimum without harming the beneficial organisms. That way, you can keep a balanced ecosystem in your farm.
What is neem oil?
Neem oil is derived from the Neem tree. It has been used in India for centuries and has become the de-facto treatment for organic farmers all over the world. Made by pressing the oil out of the seeds and fruits of the Neem tree, this stuff is a pure vegetable oil that has all the advantage of the tree’s natural pest resistance.
What does neem oil treat?
Neem oil can impact a wide variety of pests, over 400 different insect varieties as well as most fungus. The best part is, it protects against the neem tree’s natural enemies but doesn’t seem to harm more beneficial organisms!
Protects Against Pests
- Spider Mites
- White Flies
- Fungus, Molds & Mildews
- Caterpillars & Moth larvae
- Snails & slugs
Doesn’t Harm Beneficial Organisms
How does neem oil work?
Neem oil doesn’t directly kill pests, like most chemical-based pesticides. Instead, applying it creates a hostile environment for reproduction and depletes the population over time. The oil enters the insects and interferes with insects reproductive system and the oily coating on the leaves impacts egg viability. The whole environment becomes toxic to the pests, and after a few generations of low birth rates, the population collapses.
How long does it take to work?
You should start seeing improvements after the first application, but it generally takes several applications over a few weeks to get the problem completely under control.
Will neem oil completely get rid of my pests?
No. These pests have evolved over millennia to be diverse and resistant. The most costly and caustic commercial chemical treatments won’t completely eradicate a pest and neither will neem oil. If it can’t safely be done, then maybe complete eradication shouldn’t be the goal of a pest treatment, but instead, we should strive for achieving a balance.
Neem oil won’t completely get rid of your pests, and you shouldn’t believe anyone who tells you their solution will. What neem oil will do is help you keep the pest populations impact to a minimum without harming the beneficial organisms. That way, you can keep a balanced ecosystem in your farm.
How do you use neem oil?
Neem oil is typically applied as a topical foliar spray that is a mixture of warm water, oil, and soap as an emulsifier. Coating as much of the surface as possible is essential. For mites and other insects, it is doubly important to cover the underside of the leaf, since that’s where they hang out. Its almost impossible for them to attach an egg sac to the oily surface.
You can apply any time of day, but I like to apply just before light out so that the oil can sit on the leaves longer.
How often do you use neem oil?
Spraying your plant once a week is a great way to prevent pests. If you have an active pest problem, you should spray once every other day until the population is under control.
How do you make a neem oil spray?
What you need
5ml Neem Oil: – I use pure, cold pressed oil.
2.5ml Soap: Oil and water don’t mix, so you need soap to bind the spray together. I use Dr. Bronner’s mint soap since it’s organic and the strong mint brings its own beneficial anti-pest properties. Any liquid dish soap will work as an emulsifier.
1 Liter Hot Water: You will need to keep the spray warm while using since the solution will separate as it cools.
1 Liter Spray Bottle: Any clean spray bottle will work.
These ratios are for pure, cold pressed neem oil, Consult your neem oil label for exact proportions for your product.
Step 1: Warm the neem oil
Neem oil is so thick that it’s almost solid at room temperature so you will need to warm it before use. Run hot water over the sealed container or put in a bucket of hot water until it is warm enough to pour.
Step 2: Mix together
Fill the spray bottle with hot water and, once the neem oil is pourable, add neem oil and soap, Replace the spray bottle lid and shake vigorously for a full minute.
Step 3: Apply
Spray all surfaces of the plant until they are dripping with oil. Pay special attention to the undersides of leaves and at the base of the stems.
Is there something stronger?
If the infestation is particularly severe or you want to take a more aggressive approach, there are very effective ‘kill-on-contact’ organic solutions out there. These are generally made with a combination of neem, rosemary, mint and other oils. We recommend that you only use products that are specifically formulated and tested on cannabis, as we’ve documented some bad results with commercial household organic solutions.
We have had success with Bonide Mite-X spray treatment. It’s an organic solution made of botanical cottonseed, clove, and garlic extracts and works as a broad spectrum pesticide which eliminates a wide range of insects including spider mites, aphids thrips, broad mites, russet mites, and whiteflies. Unlike with neem oil alone, spider mites die on contact. Eggs are suffocated within 12-24 hours.
Can I get a premade spray?
If you want to buy something, you can bet that someone wants to sell it to you, and this is no exception. There are some good solutions, but they can be a bit more costly than mixing your own.
Where can I get neem oil?
We recommend Dyna Gro’s pure, cold pressed oil, but any cold-pressed neem oil with work great. You can find neem oil at your local gardening center or online.

How to Use Neem Oil in Marijuana Growing
Neem oil is one of those basic products that should not be missing in your grow staff
If you are one of those who wants to grow their marijuana plants in the most natural way possible, neem oil is one of those basic products that should not be missing in your grow staff. Today we talk about Neem Oil origin, properties and uses to finish our post with the most common pests and other curiosities about this product. A product which is extracted from the tree that gives its name to the oil, the indian tree Neem.
Yes, I know. I’m sure you’ve heard many times about Neem oil, otherwise, probably you wouldn’t have stopped to read this post in our PEV Grow Blog. But I am also convinced that, although you know some things about Neem Oil, maybe you need to look into the last hints about Neem Oil applications, otherwise you wouldn’t be reading this post. I’m not mistaken, right?
A brief introduction
Of course, I am not trying to make this article into an encyclopedia or the great guide about Neem oil, but I would like to seize the following lines to share with you all things or at least many subjects that, over the years, I have been learning about Neem oil and also all the benefits its use brings us in the crops and, in particular, marijuana crop, which now is the most important to you and me, isn’t it?
Would you like to accompany me? I will love finally you do and I will like much more, that at the end of the text you can tell me, not only what you think, but also if you have something else to add or to correct, because it is clear that there are always concepts falling out of my hands and I would be glad to know them from your own hand, ans also you may have some doubts not answered yet regarding Oil Neem uses.Shall we begin then? Let’s go with the basics.
What is Neem Oil? Origin and properties
This oil, which is widely heard of, especially among those who are in favor of growing their plants in an organic way, owes its name to the tree from which it is extracted, in particular, from the Neem tree native of India, although today is grown in other countries with similar climates, ie tropical and subtropical.
In this regard, there are numerous countries in south America wherein we will find this tree, in fact, is also known on the other side of the Atlantic as Margosa or Lila India. Burma, in addition to India, as we said before, is another region in the world wherein you can see grow this type of tree that usually reaches 15 or 20 meters in height, although rarely can reach 35-40 meters .
When tree Neem blooms, their flowers are white beautiful colored and their fruit are slightly elongated as olive fruits, but somewhat longer (they can reach 28 mm long and 15 inches wide). Their color is yellowish and their flavor is a bit sweet, but it is not very pleasant in the mouth, at least not when it is in its purest state. So if you were wondering what does Neem oil taste like, I think I’ve just gave you an answer.
And, now that we have more data about Neem oil tree, we need to know where it comes from, even though I’ve just given you a clue. Indeed, this natural product is obtained from the fruits and seeds of that tree. Its most common use occurs in agriculture, but it is not the only one. We will also find Neem oil in natural and ayurvedic medicine, as well as in cosmetics or other sectors as we will see later.
But how is Neem oil extracted? There are two ways to do it mainly:
–Pressing and grinding the seeds and leaves of this tree, a process that can be made cold or hot. It is said that this is the most effective method for the oil to retain all its properties, especially if it is made hot. This would be the purest oil you can obtain, loaded with the majority of active principles of interest to us.
-By solvent extraction (industrial organic solvents, even though you can use non toxic solvets such as ethanol) from seeds and fruits. In case of using toxic organic solvents, you can diminish the quality of this method compared to we have mentioned before and its use is normally restricted to soap production.
The raw and clean extraction leaves us a by-product that is known as Neem powder. At PevGrow, in fact, we have this product in powder form and its use is ideal for: organic farming as a basis of preventive control of insects proliferation responsible of pests in the cannabis crop. In addition, this product does not leave waste in treated crops, so its use is very safe.
Neem powder ECO
Returning to pure Neem oil, one of the ways to identify it is by its brown color on the one hand (the tonality can vary between the one that comes closer to yellow or orange and the one that has darker shades) and its strong aroma , on the other hand. In fact, experts say it smells like peanut and garlic. Curious mixture, right?
Although it is true that it is used in the country of origin within traditional medicine remedies, there are several studies that do not recommend their intake, in fact it is not a product for human consumption, but a phytosanitary product because it contains elements (active principles) in the composition that participate in its biocide action, helping those active principles to increase their activity.
In any case, what interests us most now is its use for our marijuana crops, and do not worry about its taste, since it will not affect the taste and quality of your final harvest if Neem is used correctly , respecting the security deadlines.
Yes, Neem oil is ideal to take care of your crop, mainly because it helps us to prevent and treat many cannabis pests, acting as a natural repellent in case of the pest has not occurred and as a natural insecticide in case we have not been able to control it before.
But what is really good is that its use carried out correctly does not affect people or animals, so it can be used both in indoor and outdoor cannabis crops, avoiding, as we said, the appearance or propagation of pests, especially insects such as whitefly, aphid, mealybugs, caterpillars, leafminers, thrips or red spider, among others, as well as can prevent the appearance of certain types of fungus which attack cannabis like mildew, botrytis or alternaria. It is recommended to blend pure neem oil with either potassium soap or sodium bicarbonate to promote fungicidal action.
As I said before, Neem oil has been used for centuries, mainly in agriculture, but in its country of origin is also used in traditional medicine and Ayurveda. And, although there are not many studies on the characteristics of this oil, its main properties are known: it is rich in Omega 3, 6 and 9. In particular, it is associated with antiseptic, antiparasitic and anthelmintic properties. In the same way, it is known that one of the main properties of the fruit from which this oil is extracted is that it is purgative.
But in addition, and here we speak of more scientific terms, which we find very interesting if we want to understand the benefits of its uses in our marihuana crop, is that neem contains more than 50 tetranortriterpenoids, being the best known and active Azadirachtin, which exerts an emetic action (induces vomiting and inhibits feeding) in the invasive insect.
Thus, Neem oil, unlike other industrial insecticides, does not directly kill insects or invaders that try to invade our crop, but prevents the insects from feeding, reducing the chances of their reproduction, so that finally or die or disappear. This prevents the pest from spreading, without forgetting that if they are trying to reach our crop already treated with neem oil, the mere smell of this oil will repel them. And all this being a product 100% natural without risk to human health. What else would you expect from this natural product?
