Neem Trees

I'm an organic coconut farmer living in Brazil. Here on our farm, we use a natural pesticide made from the leaves of the neem trees that grow here. Today, I would like to show you how we do this.

For those of you who aren't familiar with the neem tree (Azadirachta indica), it is an evergreen tree which is found in tropical and sub-tropical areas. The neem tree has many uses including medicinal, culinary, and as we use it on our farm, as a deterrent to pests. It is related to the curry tree but where a curry leaf tree is called a sweet neem, this neem is considered bitter. The tree grows rapidly about 10 feet a year and the seeds are encased in a skin which holds a juice.

Some of the birds we have here will suck the juice out of the berry and others swallow it whole. The monkeys love them as well and can often be seen sitting in the trees eating them. The bats take the berry and fly off with it causing young neem trees to be scattered around bases of many of our trees here. The juice that surrounds the seed, is okay for the animals but I have tried it and it is rather bitter and unpleasant.

The neem trees are seen a lot in Brazil in city centers for their mosquito repellent properties and because they are a fast-growing tree. The dark green serrated leaves are also attractive and are excellent as a dense shade tree. They are also resistant to drought, in fact, too much water will damage the roots and cause the tree to turn yellow.

Using Neem Leaves as a Pesticide

We have 400 dwarf coconut trees that we spray with our neem pesticide. Don't get too hung up on the term pesticide, it isn't killing the bugs, it is preventing them from chewing the leaves of our trees. If the insects are solely reliant on eating coconut palm leaves then they will eventually starve, or at least on our farm. Unlike a commercial product which kills the insect on contact, this doesn't occur when using this neem mixture. We are coating the plant with a substance the insects don't like. Instead of killing the insect, we are protecting the plant.

We use this natural pesticide for:

  • aphids
  • whitefly
  • grasshoppers
  • caterpillars

These are the main insect problems that we deal with on our farm. Although we spray regularly, our trees are also checked daily so we can stop an infestation before it happens.

I want to clarify that this article is about using the neem leaf.

For a more concentrated version of the pesticide, the neem oil can be extracted from the seed. This is done by grinding down the dried seeds into a powder using a grinder or a mortar and pestle. This powder can then be reconstituted with oil. If you don't have access to neem trees or you prefer to purchase neem oil, this is produced from the seeds, not the leaves.

The neem oil, although more effective than using the neem leaves, is less pungent to smell.

** Update**

As I am writing this in the middle of December 2017, our neighbors, both upwind and downwind, are suffering from an infestation of whitefly on their cashew trees. We have 3 large mature cashew trees here on our farm and although they haven't been sprayed with the neem solution due to their size, we don't have any whitefly. My husband believes it will be in our best interest to spray our upwind neighbor's trees and also near our fence. This will make an unpleasant barrier for the whitefly and hopefully confine them to a smaller area.

Neem is a Pesticide

A pesticide targets many insects whereas an insecticide is specific to one.

Separating Neem Leaves

Removing the Leaves

Once cut, we bring the small cluster of branches back to our patio area. This next part, of removing the leaves from the stems is time-consuming and also hurts the back. It isn't that it is difficult to do, it is just repetitive and we have yet to find an easier way to do it.

We simply sit down and drag our hand down the stem allowing the leaves to drop into the bucket. We continue doing this until our bucket is full and then it's time for the next step which takes place in the kitchen.

Chopping Neem Leaves

Chopping up Neem Leaves

To chop up the neem leaves, I use my food processor. I fill the container without packing them too tightly. As I put the leaves in, I ensure there are no stems or seeds which may damage the blades of the food processor.

I then switch the machine to pulse until I see movement at the top, only then do I turn it on high. If I switch it on high from the start, I'd end up with finely chopped leaves at the bottom of the processor and uncut leaves on the top. What you want are leaves roughly the same size.

This could be roughly chopped using a cutting board and a knife if you don't have a food processor or blender. Just to clarify, I don't add any liquid to this, I am just chopping up the leaves.

Making Neem Tea

Don't be put off by the term, tea in the title. This is just the stewing of leaves in water. We don't use warm water for this just our normal well water from our faucet.

The bucket of chopped up leaves is put into a 50-liter plastic barrel. We fill this half full of water, put the lid on and leave it for 3 days to brew.

You'll know if your mixture is ready as it will smell like a cross between urine and onions. Not a pleasant smell but effective against insects.

Adding Oil and Detergent

Using another barrel, we strain the mixture which has brewed for 3 days, through a nylon mesh sieve. An old t-shirt works equally as well. This removes the leaves and we then have our mixture.

To make sure the pesticide sticks to the plants and doesn't just run off, we need to add oil and dish soap. For this, we use 3 ounces of cooking oil and the same of dish soap. The role of the dish soap is to break down the oil, and the role of the oil is to make it stick to the leaves.

The stewed leaves from your mixture can be used in your compost heap or around the base of your plants.

Spraying Coconuts and Leaves

Using a Sprayer

As you can see from our photos, my husband uses a backpack style sprayer. This carries 10 litres which is a little more than 2½ gallons. You may be able to handle a larger one but my husband is 67 years old and an amputee. Walking from tree to tree with the sprayer on his back keeps the oil and detergent mixing. If you were using a hand held spray bottle, a quick shake before applying is a good idea as the mixture may separate.

Ours is a hand-pressurized mechanism which works off a lever on the left-hand side of the sprayer. We have extended the nozzle length on ours to ensure he can reach the upper leaves of the coconut trees without having to use a ladder.

Chapin 63985 4-Gallon 20-volt Wide Mouth Battery Backpack Sprayer, Powered by Black & Decker, 4-Gallon (1 Sprayer/Package)

This holds 4 gallons of liquid which will weigh 32 pounds when fully loaded not including the weight of the sprayer. The load is spread across your back making it more comfortable but this is a consideration before you buy. This one is self-pressurized which is a bonus, no more pumping away to keep a steady stream flowing.

The large opening tells me someone has thought about the design, as we have poured the liquid into a smaller one and because of the weight, spilt some.

Some items are crucial on a small farm like ours, we have 8 acres and a sprayer is part of the equipment we need to keep us both organic and as pest free as possible.

      Hi Zoi,

      Yes, you can. Not only will you be getting the nutrient as the leaves decompose, you will also be getting some of the repellent properties of the neem tree.

      Here on our coconut farm, we are using the neem tea to spray on the leaves and when we rake the neem leaves up, I am not putting these around the bases of the coconut trees and covering them with palm leaves so everything begins to rot in situ. I have read that coconut palms, will absorb systemically the repellent of decomposing neem leaves. Some people compress them into what they call a 'neem cake' but I just include it with other rakings from the garden.

      I would say, mulch away!

      Hi Mary, I have a small container garden. Next to my house is a neem tree so at this moment there are huge piles of fallen neem leaves. I was just wondering whether I could use the fallen dried leaves as mulch. Thanks.

      Hi Gregory,

      Yes, the chopping up the leaves is to speed things up. Much as the same for compost, smaller pieces break down faster.

      Regarding keeping the leaves. My tendency would be to dry them first, then put them in sealed bags or even freeze them. Without drying them you may end up with them rotting.

      Regarding question 3, I have looked all over that bucket and it doesn't say the capacity of it, merely the weight of what it contained when new.

      Your calculations sound fine, but if your plants are delicate, I would start with a weak solution. We use ours on our coconut trees, but the leaves and pods are thick and robust.

      I can see no reason not to use the branches. In fact, there are people who sell them as chewing sticks (dental) because of their antiseptic properties.

      Also, you can use both the leaves and small branches as a mulch around your plants. I have read that as it breaks down the plants will absorb many of the repellent properties working as a systemic pest protection. This, however, I can't confirm the results, unlike the spray which we have seen a reduction in insect damage to plants.

      Thanks for your questions and good luck.

      Thank you, Mary, for the post and your responses. I have a few questions. I did check most comments, but if I missed the answer I apologize.

      1. Just before the steeping, you put the leaves through a food processor. Is this to speed up the steeping or do the leaves have to be ravaged to get a good tea? I am in no hurry. Could I put the leaves in a bag and stomp on them and then let them steep for a week or two?

      2. I do not need that much tea.(For now. If I do this right, I will share the tea with neighbors.) Could I put the freshly picked -but not bruised- leaves in sealed bags for any extended time?

      3. Is the ratio of leaves to water that important for the tea? I assume the yellow bucket has a 5 gallon capacity and the chopped up leaves give you about 3 gallons. So is that about 3 gallons of leaves to 7 gallons of water? In my case I was thinking about filling a 5 gallon bucket with 1.5 gallons of leaves and 3 gallons of water. For every gallon of prepared tea I would add 0.5 ounces of cooking oil and soap.

      4. What about steeping the branch? The branches I have access to are not that thick. Could I cut them into 3 or 4 inch pieces and let them steep for months? I live in a city, but I want to minimize waste.

      Appreciative of your time and consideration.

      Thanks for the suggestion. I will mention this to my husband for our next batch.

      I can see boiling the mixture will speed up the process, we leave ours out in sun for 3 days.

      Suggest you try baby oil in place of cooking oil.

      Have used neem in our plant nursery for about 30 years, works wonders when blended with lime liquid detergent and baby oil, leaves boiled in water for 30 minutes then left to cool overnight covered, then strained blended and bottled, unused portions should be kept in a cool dry dark place.

      Hi Rajkumar,

      I'm not sure if you're asking a question about UV light when using the neem tree solution.

      If so, it's an interesting question as all of these things, UV, amount of hours of sunlight, rain, watering schedule, soil conditions etc can affect a plant's growth rate.

      When people speak of UV they often only think of it in relation to using sunblock on their skin and not the effect on plants.

      Where I live in Northeastern Brazil, our UV can be in the extreme category at number 11. I haven't noticed any negative effects on our trees due to the UV and the use of our neem solution.

      In fact, we are seeing fewer insects which eat our leaves. Both upwind and downwind from us the cashew trees are covered in whitefly, and we have very little.

      We are also seeing a reduction in a type of large grasshopper we have here.

      If you have the opportunity to use neem leaf as a natural protection for your plants, do it.

      Hi John,

      Yes, what you're probably seeing is an iridescent residue from the oil. The oil is the agent which holds the neem liquid on the leaf.

      Remember the neem is a deterrent for insects, it doesn't kill them, it just makes the plant less desirable for them.

      Hope that helps.

      I haven't tried drying the leaves and preserving them but I can't see why that wouldn't work. The only problem might occur that the small particles may clog your sprayer. I can't imagine that it could be so fine to pass through a spray nozzle.

      The powder could also be used to put around the base of the plants as I have read that it will be absorbed by the plant and 'may' develop and inbuilt insect protection. Much as is suggested when people eat garlic to keep insects away.

      Regarding using the neem oil in place of cooking oil. I see no reason not to if you have a source of it. Grinding down the seeds would be labour intensive, but of course, you can buy it. Cooking oil is just an inexpensive option.

      I am unsure about the benefits with regards to insects which target cotton. I know that with many GMO strains of cotton, this has allowed a rise of secondary types of insects. I would try it and see how you get on. We are seeing a reduction of whitefly, and grasshoppers on our trees although in our area, others are having a bad season for them.

      Let me know how you get on.

      Hello Mary.

      Thanks for sharing wonderful information on neem leaves. I want to discuss a idea with you about the said topic.

      If we get dry the neem leaves in sunlight or in the room without sunlight. Then grand the dried leaves to make it a thin dry powder and store it for future use. Can the water solution of this leaves powder be used in spraying against insect pest?

      Further what if we use the neem oil with this powder instead of cocking oil?. What you suggest if we use this neem solution against cotton insect pest? I would love to hear from you.

      Hi Mekonnen,

      It's an interesting question because we have those fleas here in Brazil. Here it is called bicho de pe which translates as foot bug.

      I can't say whether neem leaf spray would offer protection or not since the Tunga penetrans lives in the upper layer of sand waiting for a host. Both our dogs and ourselves have had these in our feet. I rarely go barefoot because of them.

      We have used the neem spray on our trees to keep insects at bay but I can see no reason for not spraying the ground around a living area with the neem mixture.

      We normally dig them out of our feet and also the dogs' paws. Then we use a disinfectant like Betadine on the open sore. The larva which is removed can be placed in isopropyl alcohol to kill it.

      Let me know if using the spray works on the fleas.

      Thanks for your question.

      Hi Andrea,

      By leaving the leaves soaking for three days there should be no problem.

      We check our trees daily when we water, so we can nip any infestation before it starts.

      As a preventative measure, I would say once a month. This should be done when you know you will have a few days of dry weather to give it the best chance to stick to the leaves.

      Hi Sourav,

      My answer would be, I'm not sure. Did you add any oil to the mixture, that helps the mixture adhere to the plant. Dish soap is added to break down the oil so you can get a homogenous mixture. Aphids, because of the sticky residue they make, may make the mixture difficult to stick onto the plant.

      The neem is more of a repellent, to keep the insect from staying there in the first place. In essence, it is making the plant unattractive to the insect. When we have white fly we will scrape off as much as possible or even cut off the leaf and burn it. Then the rest of the plant will get sprayed.

      I was unfamiliar with the plant you mentioned but it sounds like it is toxic so I'm surprised you have an infestation.

      I hope by using the neem solution with oil and soap, any future problems will be averted.

      Thanks for your question.

      Hi Kate,

      I haven't tried adding peppermint soap but I can see that adding it could only be beneficial. The soap can also help to break up the oil in the water (in lieu of the dish soap). I know that peppermint is supposed to a good as a repellent for many insects.

      Planting mint (in pots) can also help to keep them at bay.

      Regarding using it on your kids. The neem solution we use mentioned in this article, is too strong, to be used on humans. Although neem is used in many insect repellents, it is a small amount.

      Good luck with your garden.

      I wanted to stop in and say thank you. I live in hawaii and had a recent infestation of aphids (my first time growing a garden) and knew of neem but didn't know what to do!

      Turns out I had some on my 2.5 acre farm! I just finished up the process today and am very excited.

      Question, some sites suggest using a peppermint soap like dr bronners. Have you ever put peppermint in your mix?

      I put some in mine (mainly for smell) because I plan to use it as repellant for my (4) kids.

      Again, thank you for posting this. Much appreciated.

      You're right, in the combat of insects inside and outside the home, neem can play an important role.

      Thank you for your idea about the neem oil and camphor. It can be quite a savings to use natural and inexpensive products such as neem and camphor. Commerical products can be pricey.

      Mary, Loved your article on neem leaf pesticide and answers to questions on it.

      Just to share, neem oil with a few small camphor pellets is used to repel mosquitos in homes. It is just filled into the repellent containers of commercial mosquito repelling gadgets ( 'Good Night' or 'All out') popular in India. The idea is just to utilise the available, factory made evoparising gadget. Camphor also contributes to the pleasant fragrance.

I just suck on it and spit the skin and seed out. A true gift from mother nature. I have just pulled out my tea and googled for advice and found your site. You have reassured me in what I am doing.

      Hi Jennifer,

      Here in Brazil, the neem tree is planted not just as a shade tree but as a natural repellent for mosquitos both privately and by the city councils.

      Many homeowners will make a mixture which I've described above, and use a hand held spray bottle, spraying around the outside perimeter of their house. Obviously, they make less of it than we do.

      I wouldn't spray it on the dogs, however, as I have never tried that, and I don't know if it would be an irritant.

      Our dogs are often rolling in the neem leaves which fall to the ground, as well as my citronella plant. Perhaps this is their way of coating themselves in a natural repellant.

      I do know that the citronella will cause a reaction as I have seen it on myself when I have been thinning out our plant. I had a mild reaction of contact dermatitis from it. It was a reminder to me that just because it is in its natural form doesn't mean it's safe as many plants are quite potent.

      Both neem and citronella are used in many commercially prepared mosquito repellants. If you have access to a neem tree, I would suggest you try it in the garden and around the outside of the house.

      Thanks for reading and your question.

      Hello Ayikobua,

      I'll answer your second question first. The neem seeds hold more oil and are thus more potent than the neem leaf tea mixture. We don't have a mechanized way to crush the seeds effectively here on our farm so opt for the easier method of using the leaves.

      On our farm, we walk around the trees frequently. When we are irrigating, we are checking each tree daily. This means we can control any infestation before it starts. We don't have a set routine for spraying, we spray when we see a problem. Normally our method is, where possible we wipe palm leaf removing what we can see. Then we get the spray ready (remember it takes 3 days to brew), then we spray the tree and those around it.

      We feel the best way to keep harmful insects at bay is by observation and removal of the insect. If we see an excessive amount of white fly, for example, my husband has been known to cut the leaf off and submerge it in the lake. The insects are either drowned or eaten by fish.

      Something else which I didn't mention in my article, neem leaf can also work as a systemic repellent. It isn't something we have done yet, but plan to. By placing the leaves around the bases of plants and trees and allowing them to decompose, their repellent properties are taken up by the tree. Many people mulch them up to speed up the process, they call it a neem cake.

      I hope this has answered your questions and I hope you try the neem leaves as a natural repellent for your plants. Thanks for reading.

      Hi Ripplebuzz,

      We use fresh neem leaves and leave them to soak in a large plastic covered barrel.

      Although we didn't heat the water, it gets quite warm and then we leave it for 3 days to brew.

      Here at our home we don't have plumbed hot water so when I want to wash clothes in something other than cold, I put a large tub of water outside in the sun and use that.

      The temperature of the water inside the barrels of neem leaves will also become quite hot helping them to extract the repellent properties into the water.

      Hi Niki,

      Sorry, I really don't know. If the powder is made from the seeds it will be more potent than if it is made from the leaves. You don't say whether you are hoping to use this medicinally or as an insecticide. I would refer you to the friend who gave it to you. What quantities does he/she use?

      Something else I would like to mention, just because it is natural, doesn't mean any quantity is safe. Many plants are toxic.

      It appears they do grow in parts of Florida. I will say they don't like to be in standing water. They put a tap root down which can go deep, more than the height of the tree. We are very close to our water table here and although I didn't lose any neems (although, they did go yellow and lose a lot of leaves), I lost a curry tree (sweet neem) due to the roots being underwater for maybe a month.

      They are such an attractive tree, I hope you can find it. There is a place called Neem Tree Farm in Brandon, FL. I know nothing about them other than their details on the internet. Your local nursery might even have them.

      People here trim them into almost a solid shelter of foliage which is ideal as shade but is so thick it will kill the grass underneath. Other than all the seeds they drop, I can't think of a bad thing about the neem tree. We have them growing close to the house for shade but the birds and the monkeys love the juice from the olive-sized casing which surrounds the seed.

      Hello Chitrangada,

      The neem tree has so many uses, and until I moved to Brazil, was unaware of it.

      I need to explore more of its medicinal properties. We often look on Indian websites for natural ways of using the plants we have growing on our farm.

      Thanks for reading and your suggestion.

      Neem is an amazing tree with multiple benefits. You have described the process in easy to understand manner. I am sure it will help many readers.

      Besides that Neem is also used for medicinal purposes in Ayurveda. And nothing like an antiseptic head bath with neem leaves boiled water.

      Thanks for sharing this useful information!

      Hi Dora,

      It is an amazing tree and from what I read, does grow in the Caribbean. This mixture is easy to make and I'm certain your neighbours will be able to benefit from using it as we have.

      Thanks for reading.

      Thanks for this information on the neem leaf and its uses as pesticide. Until now, I had only heard of neem tea. I will recommend this article to my Caribbean neighbors.

      Hi Marlene,

      You're right it is a beautiful and useful tree. Although native to India, it is now found in many countries.

      In India, it is used in ayurvedic medicines although here in Brazil, it's used mainly for shade, and its insect repellent properties.

      Thanks for reading.

      I am a big fan of organic pesticides. I have never heard of the Neem tree, but it is a beautiful tree. I wish I could grow it here. Lots of uses for this tree. Thank you for explaining the many ways to use it effectively.

      I'm glad you found it interesting. Our trees are doing well, we are now in our wet season and they are going through a growth spurt.

      I'm a firm believer in Mother Nature wanting a healthy balance and provides the answers to many problems.

      Thanks for reading.

      I really enjoyed this hub as I love finding out how growers deal with insect problems organically. You have explained the process very well in how to use neem tree leaves as a spray. I hope your coconuts are thriving.

      RTalloni ,

      Not sure which area you live it but it may be possible to grow it if you're in the southern States.

      I know in India they make a 'neem cake' of compressed neem leaves and use it in their gardens as a fertilizer. I think it also helps with nematodes.

      Thanks for your visit today.

      Hi Bill,

      This tree grows like crazy here, in fact, my lawn is covered in small neem trees which have sprouted. It is considered an invasive plant in some countries. You may have seen it used in repellents, shampoos, skin treatments etc.

      For us, it is used for the coconut trees and we spray around the house to retard insects.

      Great to hear from you.

      Hi Peg,

      That is a shame about your Ash trees. You've touched on something I didn't mention in my article, boring insects.

      We have a few different ones which can get into our coconut trees. We lost one to the boring insect and burned the tree to rid us of any possible eggs. That was about 3 years ago.

      There is also another type of microscopic insect which burrows under the young coconut, resulting in a dead nut. This is an ongoing problem so we spray as soon as a new flower pod of coconuts open. Coconuts are self-pollinating within the pod so we don't need any helpers which may be carrying a potential problem with them.

      If we think of the neem solution as a protective repellent on the tree instead of a pesticide, you can see why it needs to be an ongoing exercise.

      I'm pleased you found this interesting, thanks for reading.

      Thanks for sharing your method of making a repellent from neem oils. I'll be checking to see if we can get a tree for growing in our area. I would like to mix chopped neem in with mulch.

      How to use it? I've never heard of it, or the tree. LOL But I love that you believe in organic and it's always nice to learn new things, so thank you for the education.

      This is incredible. You've described the process in such a way that it sounds easy, although, I would imagine time consuming. I love that you made your own solution to the pest problem. I'd heard that Neem oil will deter boring beetles but when I used it, I was too late and the bugs had already destroyed one of the Arizona Ash trees we'd had for many years. Thanks for sharing this interesting method of pest control.
