Neem oil also inhibits insect food intake and alters the hormones they produce and their reproductive cycle.
Neem trees originate from India. The oil extracted from the neem tree is made using seeds found in the neem fruits. These tiny drupes resemble olives and can grow at 1.1″ (3 centimeters) in length.

The late afternoons or early evenings are ideal for spraying flowers with neem oil because there is enough light to see and plenty of time for the oil to dry before the weather gets hotter outside.
Many bloggers advise spraying neem oil in the mornings but based on my own experience, I’m not my favorite this strategy. We damaged a few tomato plants during the last time We sprayed the plants with neem oil during the early morning hours (around 6:30 am). The neem oil did not have time for drying before the sun rose, and started to cook the plant’s leaves.
We like to delay till later for this we need enough sunlight for clear vision, but we would like for the sun to sit as low over the horizon as possible.
We’ve discovered that it’s challenging to spray plants excessively using neem oil. Hence, it’s usually not necessary to rinse the oil off but neem-sensitive plants don’t respond as well to excessive spraying. Tomato plants can handle well with neem oil even when subjected to the pressure of sprays, however, I’ve found that lettuce, spinach, and other plants aren’t a fan of the heavy neem oil sprays.
