Neem oil is a powerful ally against harmful or destructive insects indoors and outdoors.
this Neem oil is deadly to at least 200 common garden pests And it may kill up to 600 people through its active ingredient azadirachtin.
This natural insecticide mainly comes from Neem But it exists in all parts of the plant.
The seeds (sometimes leaves or fruits) are cold pressed to extract natural oil, called crude neem oil or raw neem oil. Then, neem cake is made from solids.
Neem can be extracted from Neem crude oil and used in other products, leaving a clear, hydrophobic Neem oil.
There is no waste at any time in the manufacturing process. Both forms of neem oil are widely used to uniquely treat plants by creating soil wetting and foliar sprays.
What is a good neem oil spray formula and soaking liquid
Many insecticidal formulas can be made at home using neem oil. From soaking liquid to soap, only three ingredients are required.
Before making sure that there are no adverse reactions, it is best to test a small area of the plant on the same day.
Neem oil spray formula
Perhaps the most common form of neem pest control is neem leaf spraying.
Foliar sprays use a low concentration of clarified and hydrophobic neem oil to make them quickly dissipate without residue.
This means that they will kill the insects they encounter, but they will not pose a threat to pollinators or beneficial insects.
Clarified, hydrophobic neem oil can be purchased online or in garden centers, and the most common concentration ranges between 0.5% and 2%.
To make a spray, add 1 teaspoon of emulsifier to a gallon of water and stir gently to mix the soap.
Next, add 4 tablespoons of clarified neem oil to the emulsified water.
Other ingredients, such as essential oils or using insecticidal soap instead of emulsifiers, are popular variants of this basic formula.
The application is very simple, just spray the plants and soak each part evenly.
Be sure to find the underside of the leaves and any joints or cracks, as these are usually hiding places for pests.
If you are spraying outdoor plants, make sure to treat them at dusk or dawn when most beneficial insects are not active.
Neem foliar sprays usually dissipate within 45 minutes to 1 hour.
Neem Oil Soaking Soil Formula
this Neem soil soaking formula Similar to its foliar spray brothers, but with very different applications and lifespans.
To soak, start with one gallon of emulsified water and add 100% cold pressed neem crude oil.
Make sure that the oil is cold-pressed, as it loses its effectiveness when heated.
To use, just pour 2 to 4 cups of soaking liquid directly on the soil and let the plants drink.
Azadirachtin is absorbed by plants into their circulatory system and becomes a systemic insecticide that lasts up to 22 days.
Any insects that try to eat or pierce plants will ingest toxins, which means that this method is still safe to use around beneficial insects, and it is safe to use around earthworms.
Neem oil soap formula
Although the spraying of neem leaves is technically counted as Insecticidal soap, It is possible to make a more effective version for future use.
Mix 15 ounces of neem oil and 2.1 ounces of lye with 3 ounces of water in a heat-resistant glass or porcelain bowl.
Slowly heat the mixture and stir with a steel spatula until it becomes viscous.
When using soap, avoid using wood, aluminum or plastic.
Let a pound of soap cool down completely and store in a dry place.
To use Neem Insecticidal Soap, add 5 tablespoons of soap to a gallon of boiling water to dissolve it and let it cool, then add it to your sprayer and spray it like a foliar.
Please note that this soap mixture will leave residues, so please avoid any residues on the flowers to prevent accidental death of bees.
Neem oil garden spray formula rules
When using neem oil in the garden, it is important to use only pure neem formula, for example if you raise beneficial insects in the garden, you can use basic foliar spray and soil soaking.
Never dispose of your plants while the pollinator is active, because if applied topically, they may come into contact with azadirachtin before it dissipates.
Although the presence of azadirachtin is not dangerous to humans or pets, the added chemicals are not the food you want.
Do not spray plants with edible flowers, fruits or vegetables on the day of harvest. Similarly, it is best not to use soil soaking three weeks before harvest.
Finally, be careful not to get neem oil on the bean sprouts or saplings, as the oil can cause chemical burns on sensitive new growths.
