8 Tips For Watering Plants With Neem Oil
Neem oil and water can be used together as an effective way to water your plants.
Here're some tips to get the most out of this method -
1. Use A Diluted Mixture
The most important thing to remember when watering plants with neem oil is always to use a diluted mixture.
If you use a concentrated mixture, it can actually damage the plants.
On the contrary, a diluted mixture will help in dealing with several plant issues.
And it won't be too harsh on the plant, either.
Note: In case you're not sure about the concentration, it's always good to err on the side of caution and go for a weaker mixture.
For this, you can add more water to the mixture and dilute the concentration.
2. Use It In The Right Proportion
Another thing to keep in mind is the proportion of neem oil and water you're using.
I have shared the formula below, which can help you get the right mixture.
You can use the same formula for each gallon of water.
However, if you feel it's not too effective, you may increase the amount of neem oil slightly.
3. Use It For The Right Plants
Not all plants will benefit from neem oil and water.
So, before you go ahead and use this method on all your plants, do some research to see if it's suitable for the plants you intend to treat.
Also, refrain from using it on young plants or seedlings.
They won't be able to handle the mixture as well as mature plants.
4. Use It On The Right Time
When it comes to watering plants with neem oil and water, timing is everything.
You should be using it at the right time of the day and on the right plants.
This is very important because using it on the wrong plants or at the wrong time can do more harm than good.
5. Test It First
The patch test is a must before using neem oil and water on your plants.
This will help you determine if the mixture is too strong for your plants.
It's very simple to do - just apply the mixture to a small area of the plant and see how it reacts.
You may have to wait for a day or two to see the results.
If the plant looks good and shows no signs of stress, you can use it on the rest of the plants.
6. Use It Only When Needed
Neem oil can be tough on your houseplants if used regularly.
So, it's important to use it only when necessary.
For instance, if you see signs of pests or other issues, you can use it.
But if the plants are alright, there's no need to use them every time you water them.
You can simply water the plant without adding neem oil or pesticides.
7. Check The Weather Conditions
The weather conditions play a very important role in deciding whether or not to use neem oil and water.
If it's too hot or too cold outside, you should avoid using this method.
Hot weather can cause the neem oil to evaporate quickly.
Also, the leaves will probably get scorched if exposed to direct sunlight after spraying with the mixture.
And in cold weather, the mixture can freeze on the leaves, damaging them.
8. Be Careful With The Wind
The place where you spray the mixture should be protected from the wind.
If there's a strong breeze, this mixture can drift away and end up on the wrong plants.
Or, it can simply evaporate before it has a chance to reach the plants.
You can also use a piece of cloth or any other material to protect the plants from the wind.
If you don't want to follow this process, move the plant to a more sheltered area before spraying it.
So, these are a few things to keep in mind before using neem oil and water on your plants.
Next, let's look at how to prepare and use the mixture.
Things Required For Watering Plants With Neem Oil
Here's what you need to prepare this solution -
- Neem Oil
- Water
- Soap
- Spray Bottle
- Dry Cloth
Regarding the soap, you can use any liquid soap.
But I prefer dishwashing soap because it's gentle and contains no harsh chemicals.
Also, it is only used for mixing purposes, so a small amount will do.
Now that you know what's required, let's take a look at the process below.
How To Prepare Water And Neem Oil Solution
Here's a step-by-step guide on how to prepare this solution -
- Fill a spray bottle with water.
- Add a few drops of liquid soap.
- Now, add neem oil to the bottle.
- Shake the bottle well so that the ingredients are mixed properly.
- Your solution is now ready to use.
Formula For Neem Oil Solution:
1 teaspoon of neem oil + ½ teaspoon of soap + 1 liter of water
You can increase the neem oil quantity later if required.
How To Apply This Solution
Now that the solution is ready, it's time to apply it to the plants.
Follow these simple steps -
1. First, take a dry cloth and wipe the plant leaves.
This step is important because it removes any dust or dirt that might be present on the leaves.
If the leaves are not clean, the mixture will not be as effective.
And this is especially good for outdoor plants that accumulate a lot of dust.
2. Now, take the spray bottle and mist the leaves of the plant.
Cover the entire plant, ensuring the mixture reaches all the nooks and crannies.
3. Leave the plant for a few hours so that the mixture can work its magic.
4. After a few hours, take a dry cloth and wipe the leaves of the plant.
This step removes any excess mixture from the leaves.
It's not a mandatory step, though.
You can skip this step if the leaves are already dry after spraying.
5. Repeat this process once a week or as needed.
And that's it!
This is all you need to do to spray the plant.
How To Water The Plants With Neem Oil
Although watering your plants with neem oil is not as common as spraying them, it can be just as effective.
You can use this method if the soil is infested with pests or plants suffer from a fungal infection.
Here's how to do it -
1. Take a bucket of water and add neem oil to it.
2. Mix the ingredients well so that the neem oil is evenly distributed in the water.
Important: Don't use soap in this mixture.
If you do, it will damage the roots.
3. Now, water the plants with this mixture.
4. Let the roots soak in the mixture for a few hours before watering them with plain water.
5. Repeat this process till you get the desired results.
Note: If the plant is not doing well after watering it with this mixture, stop immediately.
And that's pretty much about watering your plants with neem oil.

Ideally, you should wait about 24 hours after applying neem oil before watering your plants.
This will give the oil time to work and protect the plant from pests and fungus.
However, if you haven't watered the plant in a long time, you can surely water it immediately after applying neem oil.
You should use no more than 2% neem oil in your water solution, as this is the maximum concentration that is safe for plants.
If you're using a smaller amount of water, adjust the amount of neem oil accordingly.
Absolutely!
You can also add a small amount of dish soap to the mixture.
This will help the neem oil spread more evenly over the leaves.
You can spray neem oil on both the leaves and the soil around the plant.
It's slightly different from using neem oil on indoor plants, as you'll need to be careful not to get the leaves wet.
The best way to do this is to mix the neem oil and water in a spray bottle.
And then, mist the leaves lightly.
You can also use a cotton swab or brush to apply the neem oil solution directly to the leaves.
Over To You
Neem oil is a powerful, all-natural solution for protecting your plants from pests and fungi.
It can effectively keep your plants safe from these issues when used correctly.
That said, don't use it too often.
