Neem oil has been used for centuries as a natural pesticide. There has been a lot of success in keeping the garden there free of pests. Some plants, however, find the odour of neem oil to be offensive.
This begs the question,what plants not to use neem oil on?
Some herbs, including caraway, basil, cilantro, marjoram, dill, parsley, oregano, and thyme, should not be treated with neem oil. It’s important to use caution when spraying neem oil on plants with thin or fragile leaves, such as peas, arugula, lettuce, and spinach.
However, if you aren’t cautious while mixing and spraying neem oil, the leaves of stronger plants might be burned (or even killed).
Neem oil is applied to the leaves of plants to protect them from pests and to discourage insects from making a home among them. For certain insects, the oil coating is fatal, while for others it might harm their cells. On the other hand, neem oil is a solvent and must be used correctly. The leaves of your plants will be harmed if you apply neem oil at the incorrect time. In this blog you get to know about what plants not to use neem oil on.
