In this article, we will take you through simple steps that you can use to make the neem oil yourself at home so let us get started.

How To DIY Neem Oil for Your Home Garden?

You can DIY neem oil for your home garden by collecting the needed supplies, mix the ingredients according to the recipes, store the neem oil properly, so it lasts a good amount of time, and finally by using it when and where needed and be cautious on different plants.

Neem oil can be bought from the store which may contain certain chemicals that act as preservatives while the rest of them may increase the insecticidal and pesticidal properties of the oil.

This type of neem oil can thus be a little on the pricier side because of all the added processing and chemicals. You must also be mindful that you can make neem oil at home for a much cheaper price, with ingredients found in the pantry, and in no time and they would be as effective and long lasting.

1. Collect the Supplies

The first step in making your own neem oil is collecting all the necessary supplies so that you would not waste time finding them. The following supplies will come in need: raw neem oil, a gallon of water, some liquid soap, a bottle with a nozzle, a mixing spatula, and protective gear.Neem Oil Supplies

Additionally, a few drops of rosemary oil or peppermint oil may also come in very handy. These are the ingredients needed for the simplest yet effective recipe of a neem oil spray.

You can make as many alterations as you want but keep in mind that you do not go overboard and the real purpose of the neem oil is left behind. The raw neem oil can be found at a grocery store, at a plant shop, or in a plant nursery so make sure you have the right quality of this material.

It is very unlikely that you will physically yield the raw oil because for that you will need an oil mill and a neem tree with mature neem leaves. Make sure that your raw neem oil has that bitter smell and taste, which will be a testament of its originality and powers.

You can use a normal dishwashing liquid or castile soap; either of them will work just fine. A medium-sized bucket that can hold a gallon of water will work very well for this activity and for it to become properly diluted. In this case, you should also note that the soap is what will make thee emulsification processes way easier as you mix it well.

A plastic bottle with an adjustable nozzle will work very efficiently when you will be spraying at smaller places and also when you will need to store the neem oil spray safely. Finally, the peppermint oil and the rosemary oil are only there to add a different but pleasant fragrance to the bitter oil.

2. Mix the Ingredients

The second step in the process is to mix all the ingredients that we have mentioned in the first step. Start by wearing your appropriate protective gear, which may include overall, gloves, eyewear, and a face mask, so that you would not harm yourself in any way.

This is important because stray droplets of liquid can get into your eyes or skin, causing rashes or, in some cases, burns when the sun is shining bright. The raw neem oil on its own can also be very stingy to the skin so do not use it without the appropriate protective gear.

Now that the safety is on, grab the bucket and pour in a gallon of water into it. Make sure that water is clean and that no sand or other debris is roaming around or settling at the bottom because it can ruin the make of your neem oil and also affect its performance. In addition, it shouldn’t have any chemicals too, so ensure that you aren’t using any contaminated water.

In the clean water, add two to three tablespoons of raw neem oil and a kitchen-safe washing liquid each. With a mixing spatula, mix the solution until you see that the oil is mostly mixed and its bubbles are no longer visible, and ensure that you mix a couple of drops of soap as well.

3. Dilute

After the solution is made you can now use it as it is but we would like you to add another step to the process. As the neem oil smell is very pungent and unpleasant, which is why you can aim to be adding a few drops of your favorite fragrant oil like peppermint oil, or rosemary oil.Diluting Diy Neem Oil

You can also use harmless artificial fragrances like that of vanilla or strawberry to elevate the aroma of your spray. The oil solution is now ready so pour it in a bottle with a nozzle.

The smell of the homemade neem oil is generally very strong but you can try and mellow down the bitter smell and aroma of the neem oil. You can use other pleasant-smelling oils like rosemary oil to sweeten up the neem oil smell.

This all depends on how strong the existing smell is. If it is too strong, it will be tough for you to change it even after adding a vast amount of pleasant-smelling oils to it.

Alternatively, you can use artificial fragrances to change the smell of your homemade neem oil. Make sure that these synthetic fragrances do not ruin the chemistry of your neem oil and make it less potent in its actual use, which is an antibacterial. The artificial fragrances that you use should be safe to use in food and drinking items, and you can find them in grocery stores.

4. Store Properly

The third step in the process is the storage of your neem oil solution because if not stored correctly, the oil will go bad very soon and ruin your hard work, time, and money. The neem oil should be kept away from the sun in a cool and dry place for a prolonged shelf-life.

If the oil is not stirred correctly, the color of the oil spray changes, and a cloudy appearance is seen. This type of oil has lost all sense of its abilities and can be hazardous if used, which is why the homemade one is safer to use.

Furthermore, any kind of alien substance in the solution may cause it to ruin itself. This is why it is essential that you do not leave it in the open air for a long time. It can cause problems for the spray and make its work redundant.

Note that it can be stored in any weather but make sure that the place is cool and dry and not humid and hot because that can ruin the pH of the spray.

When you make this oil, remember that the homemade neem oil may be better than the store-bought one because the stored one is made by using various chemicals for preservation and increased antibacterial properties. This is why th homemade neem oil is easy to make on your own and has a good shelf life.

The homemade neem oil can be made with very basic ingredients found in the kitchen so next time you need a neem oil spray for your plants, try making it yourself. The homemade one is also a lot cheaper than the store-bought one, so you save some money there as well.

Make sure to store the homemade neem oil in a much better way than the store-bought one because it does not have any preservatives to save it from decaying. Other than all of these points, the neem oil, either stored brought, or made on your own is a great staple to keep at home.

5. Use When Needed

The last step in the process is making use of the neem oil spray that you just made yourself at home in no time. Neem oil is used on various outdoor and indoor plants and trees to keep them safe from harmful insects and bugs.Using Diy Neem Oil

Neem oil is thus a very effective and readily available remedy and the best thing about it is that it is non-toxic to humans which makes it safe to use.

6. Be Cautious of the Usage

At the samee time, you must also be cautious that you should not use neem oil on plants with wispy and delicate leaves like that of basil, oregano, cilantro, parsley, dill, caraway, and thyme. This is why you should be cautious about using the oil on a sunny day with dry weather rather than a wet one because that can make the use of neem oil redundant.Usages of Neem Oil 1
