Neem oil is a vegetable oil extracted from the Miracle Tree thats the Neem Tree.
The botanical name of neem tree is Azadirachta indica.
Azadirachtin and Nimbin found in neem oil are the two major compounds responsible for
its antibacterial and antifungal actions.
This neem tree is native to the Indian subcontinent and can be easily grown at home gardening
level even in large containers.
You can watch a detailed video on Growing and Care tips for neem tree from an end screen
link after this video.
Now, before we discuss on which Neem oil you should purchase for best efficacy in gardening,
we will list out the best uses of neem oil for your plants and gardening.

attacks on your plants.
It is infact a broad spectrum pesticide effective on pests like Aphids, Mealybugs, Whiteflies,
Caterpillars,leaf miners, fungus gnats, Thrips and mites, Greenflies, Grasshoppers and other
Scale insects.
It kills pests in all their lifecyle stages like the adult stage or the larval stage.

It has the Anti bacterial, anti viral and anti fungal properties not only for use on
plants but also prescribed for humans and pets for various skin and hair problems.

5.
Neem cake is an excellent organic fertilizer for your plants.
Neem cake is the by-product left over after the process of extraction of neem oil from
neem seeds or neem fruits.
Its not only a source of NPK and micro nutrients for plant growth, but when mixed with soil
acts as a soil conditioner and also antibacterial and antifungal.
You can avoid fungus gnats if you incorporate about 10 percent neem cake powder in your
potting mix.
6. last but not the least is, unlike the chemical pesticides, It does not affect the beneficial
pollinators like butterflies and honey bees which are so important for a fruitful gardening.
Now, we will discuss the most important aspect of this video, based on which the quality,
composition and efficacy of neem oil depends thats the method of extraction of neem oil
from seeds.
There are three methods: 1.
Heat Pressing method.
2.
Solvent extraction method and 3.
Cold Press method.
Heat pressing method as the name implies, its using heat for crushing or pressing the
seeds to extract oil.
Solvent extraction means using a solvent like alcohol is used to extract neem oil.
This solvent extracted neem oil usually has a low price, because it is turbid and contains
a significant amount of water and metals with low content of the important compounds namely
azhadiractin and nimbin.
Heat extracted neem oil also has moderate loss of the useful compounds and less effective.
Whereas the Cold pressed Neem oil extracted without applying any heat, is the best and
effective source for neem oil.
So, when you are purchasing from a local garden store or online, make sure you check the method
of extraction mentioned on the bottle or product description.
I have provided a link to purchase this product from a link in description below.
Now Finally How to use Neem oil properly for the best effects.
Now before I start with the neem oil recipes for plants, the safety profile of neem oil.
It has few effects when concentrated form is ingested like stomach irritation causing
gastritis and vomiting.
Then Eye irritation and contact dermatitis can develop on contact specially in children.
Otherwise it has an excellent safety profile and its completely biodegradable.
Now the recipe for Neem Oil you can make at Home.
Before this, few important points you must remember:
1.
Because its an oil, it doesnt mix well with water and must be mixed with some kind of
surfactant like liquid soap or even shampoo for proper mixing and the coating effect on
the plant leaves.
2.
Make sure you do not spray neem oil during the sunlight best time to spray is in evenings
after the sun fades.
To Make the best broad spectrum PESTICIDE FOLIAR SPRAY FORMULATION for 1 litre:
Take 1 litre Warm Water and add 10 drops of liquid soap like your handwash or even some
shampoo.
Then you add 5 ml to 10 ml of Neem oil into this.
5 ml if you want to spray as a maintenance pesticide spray for your garden where you
do not have much pests.
10 ml if you have lot of pests on your plants.
Mixing this thoroughly before use is very important.
Perform a PATCH TEST to know how strong it is.
This means you Just spray this on one or two leaves and then wait for a couple of hours
to see if the leaf is wilting or burning due to too much concentration of neem oil.
If you pass the patch test, you can spray it on your whole garden safely.
Patch test may be important for newbie gardeners or if you have purchased a new brand of neem
oil from some company for the first time.
Also make sure you spray the underside of the leaves as well.
3.
How frequently should I use neem oil?
Depending on the severity of pests, use it twice a week for pest eradication phase and
then weekly once for 1 or two months and finally if everything is clean use it once every 15
days as a preventive measure.
So, there you have it folks.
