Hi David, Aphids got into my mulberry cuttings that were doing FANTASTIC until they were ruined in a matter of hours. So I'd like to make some Neem oil to counteract these insects. The Neem MM doesn't indicate how long, if at all, the oil should be heated when infusing with neem. As a neem oil spray, I would assume olive oil would work since it has to be liquid a room temperature. Any thoughts? Thank you much!! Nina

Neem oil is not an infused oil. The process of making neem oil commences with the collection of ripe neem fruits, which are then left to dry naturally in the sun. Once sufficiently dry, the outer layer of the fruit is removed to reveal the seed. Each seed contains a kernel, which is the valuable part that ultimately gets turned into oil. To extract the oil, the kernels are crushed and pressed, releasing the oil, a method known as cold pressing. This method retains the highest amount of beneficial compounds, ensuring the oil's potency. Alternatively, some producers use a solvent extraction method, which can yield a higher amount of oil but may also include solvents' residue. Once extracted, the oil undergoes a filtration process to remove any remaining solids, resulting in a clear, amber-coloured liquid. This oil is rich in various compounds, including azadirachtin, which gives neem oil its potent properties.
