What Is Neem Oil
Neem oil is a rich liquid extracted from the neem tree, commonly found in South Asia. It has an unpleasant odor but is full of health benefits. It’s an effective antioxidant, anti-inflammatory, and antibacterial oil, commonly used in skin and hair care to help with concerns like psoriasis, eczema, wounds, infections, and more.
Due to the azadirachtin compound in the oil, it’s also a natural insecticide. Azadirachtin works to regulate, repel, and eliminate plant-feeding insects without using harmful chemicals.
Difference Between Organic and Neem Oil
Any food or plant produce farmed without chemically formulated substances is organic. While not all organic pesticides will use neem oil, most neem oil products are safe and organic. Neem oil is generally good for organic gardening, but there are exceptions, with some ready-to-use formulas including chemical pesticides in their mixtures. If you want to check if a product is organic, look for proper certification such as the USDA Organic and the OMRI Listed for Organic Use seals.
Pros and Cons of Neem Oil
Repels pests but not beneficial bugs
Amazingly, neem oil pesticides fight against all kinds of pests, including but not limited to mites, aphids, mealybugs, and flies. The best part? As long as you avoid directly spraying beneficial bugs that don’t feed off of plants, they’ll be safe.
Safe indoors and outdoors
When pests come indoors, the need for an organic pesticide becomes even greater. Luckily, neem oil can work indoors to prevent disease and pests safely and reliably, though it might leave behind an unpleasant smell.
Strong concentrations harm plants
Although neem oil is organic, plants are delicate and won’t survive high neem oil concentrations. A little goes a long way, and it’s best to be conservative with your formula’s strength. Even commercial formulas avoid going higher than 3%.
Should be used sparingly
Neem oil is still a pesticide, and it’s best not to overwhelm plants with it. Try to use any pesticide only as a last resort after other natural insect-repelling techniques fail. If it’s not made for dormant spraying, don’t make a habit of using this regularly.
Diluting and Mixing Neem Oil
Ready-to-use formulas are unbelievably convenient but knowing what you’re using in your mix and having control over the mixture is just as valuable. To make a homemade pesticide, follow these simple steps and use these three ingredients: neem oil, warm water, and non-toxic liquid soap.
- Mix a gallon of warm water with a teaspoon of liquid soap. It allows the oil and water to mix later on.
- Add 1.5–2.5 Tbsp of neem oil and shake well before transferring to a spray bottle.
- Spot test the mixture on a plant and observe it, adjusting accordingly.
- When it’s done, wait until the target plant is out of direct sunlight before spraying and leaving it overnight.
Can Rosemary Oil Be Used as an Alternative
Rosemary oil is a wonderful ingredient in organic gardening as a herbal insecticide. If neem oil is out of reach, it’s a great alternative.
This powerful oil contains anti-microbial and fungicidal properties that naturally drive away moths, fruit flies, mosquitoes, and many other pests.
It’s completely safe for all plant varieties, and you can make it with a formula similar to homemade neem oil mixtures. However, it’s limited in the kinds of pests it drives away and isn’t as strong as neem oil-based pesticides and fungicides.
