What is Neem Oil?
If you are into organic gardening, you must know about Neem oil uses in the garden. Neem oil is a natural pesticide derived from the Neem Tree seeds. A great medicinal tree that is found in the Indian subcontinent and also known as the Wonder tree.
The main insecticidal ingredient of Neem oil is Azadirachtin, and it’s non-toxic to mammals, proven in studies. Unlike chemical pesticides, it’s not carcinogenic. Moreover, it’s anti-cancerous. Many scientific studies are going on to understand its positive effect against cancer.
Neem oil works as a feeding deterrent and stops the reproduction of plant pests. After application, most of the insects turn inactive and don’t feed on plants, and within 5 to 10 days, they die.
Neem Oil Uses for Garden
1. Neem Oil to Kill Pests
If you are facing problems with garden insects, then neem oil is a solution. As it is natural and completely safe for plants and pets, you can use it as an organic insecticide. Neem oil is beneficial against more than 200 species of insects, including most common pests like aphids, whiteflies, thrips, mites, and leafminers. The extensive list is available here.
2. Control Nematodes
Nematodes are known to wreak havoc in the garden, especially the Root-knot ones. Interestingly, they’re responsible for 5 percent global crop loss in the world! Spraying diluted Neem oil over the leaves and around the base of plants is one of the most effective ways to stop them from spreading, as it effectively finishes the Nematodes larvae, preventing them from hatching. Its potency is proven in a study published in the plant pathology journal here.
3. Prevent Fungal Diseases
Plants are prone to fungal diseases, and they’re responsible for damage to their foliage, fruits, flowers, and overall growth. Spraying neem oil solution over plants keeps the fungal infections at bay, as it kills the fungi and stops them from spreading to other plants as well. Proven in this Nigerian study here!
4. Keep Slugs Away
Slugs are notorious garden pests. They nibble a plant’s leaves to an extent it dies. Neem oil is like poison to pesky snails and slugs and helps in keeping them away, once it is applied. Just spray the plants with a neem oil mix, using a spray bottle. Check out this important study to learn more here.
5. Use it As a Mosquito Repellent
Gardens act as a perfect place to harbor for the mosquitoes. Spraying neem oil at the strategic places repels the mosquitoes. You can also apply the neem oil to your skin, as it’s organic and safe. Mix 2 ml of neem essential oil in 100 ml coconut or other carrier oil and apply it on your exposed skin. This will provide you protection for 3 hours. Details on the research here.
6. Prevent Rust Diseases
There are over 5000 species of rust that harm a big list of plants. Spraying neem oil over the affected plants prevents the leaves from developing the rust spots and also saves the plant from several other diseases. You can also use other essential oils like tea tree, thyme, clove, etc. for this purpose.
7. Control Lawn Grubs
Lawn grubs can be very harmful to your lawn as they tunnel under the soil and cause damage to the roots of grass and other plants. Spraying Neem oil on the lawn and around the roots of the plants is one of the most effective ways to control Japanese beetles, stopping them from laying eggs that later become larvae (Lawn Grubs).
8. Protect Fruits and Berries
If you have fruits and berry trees in your garden, then Neem oil is the best way to protect them. Spray the plants with neem oil, right before they blossom and again when their petals drop. This will ensure that pests like fruit flies, leafhoppers, and aphids, will stay away.
9. Pests Never Become Resistant to it
Even after repeated applications of neem oil in the garden, it will be as effective on pests, as it was on the first day. Insects and pests never become immune to the Neem oil, meaning it’s always effective against them. Check out a good read here, which elaborate this claim more.
10. Not Harmful to Pollinators
As we all know, pollinators like bees are becoming increasingly rare due to climate change. And to make matters worse, synthetic pesticides are also responsible for their deaths. Using neem oil as a pesticide won’t harm bees and butterflies, as they do not feed on the leaves.
Neem oil never makes its way to the nectar of the flower, thereby keeping the bees and butterflies safe! This way, you will also be playing an important role in the conservation of the environment.
Neem Oil Insecticide Recipe
Preparing an organic neem oil pesticide spray for the garden is fairly easy. For this, you’ll need just neem oil and water. To make it effective, you can add mild liquid dish soap as well.
