These are Neem leaves and we’re going to make an insecticide for plants using these. To begin with, separate the leaves from the stems Another approach is to use a blender to breakdown the leaves and stems to really small pieces. As for me, I just remove the leaves like this…. Leaves are easy to remove and they can be pulled right off the stem. The stems can also be used to make insecticide Even the branches can be used. Cut to really small pieces if possible Others even use a hammer to squeeze the sap from the branches There are two known ways to make insecticide using Neem leaves One is add water and to ferment these for three to four days The other is by boiling for five to ten minutes. In this bottle is an example of fermented Neem leaves This is how the water of Neem leaves look like when boiled for five to ten minutes. So the one with the hazy color is fermented while the other with green color is from boiling neem leaves. If you want it faster, boiling then is the better option. But there is a possibility that by boiling some of the important substance may dissipate resulting in a less potent insecticide as compared to this one obtained thru fermentation. But of course boiling neem leaves is also an accepted method in making insecticide. The smell of both stinks but the fermented version is stinkier. So it is your option whether you want to boil or ferment Neem leaves. To preserve, you can just put in your refrigerator and it can last for a few days more. To use, just spray it directly to your plants… Being organic, neem leaves insecticide is basically an insect repellant. As a repellant, it will not kill beneficial insects unless they are immobile. To make it kill on contact, you can add a spoon of dishwashing liquid and another spoon of oil to one liter of water. Adding oil and dishwashing liquid will help the substance to stay longer on the pant and also helps in making the insecticide more potent. Neem oil on the other hand is different Neem oil is made from seeds by cooking in oil crushed dried Neem seeds. But there are also those who make Neem oil using leaves, stems and branches. Although not as potent, Neem leaves can also be used to make Neem oil applying the same method used in making Neem oil from seeds. Before using this insecticide for the first time, make sure to test spray just a few leaves nd observe the plant’s reaction for two days. This is because some plants may have adverse reaction to this insecticide. Spray this in the morning or in the afternoon when the plant is already in the shade. Please remember that even same varieties of plants may still have different reactions owing to the differences and peculiarities of their growing conditions. If after two days the plant did not have any adverse reaction then that is the time that you can spray the entire plant. Thank you for watching. Please Subscribe.
