How to use Neem oil for garden pest control
Neem oil is a natural vegetable oil that is acquired from the seeds of nim trees. Neem oil has many applications in gardening and in medicine. It contains two important elements, which serve gardeners pretty well. One of them is Azadirachtin, which is used in a lot of store-bought pesticides. Azadirachtin is toxic to insects, but it is biodegradable and not a threat to mammals. It is known to affect over 200 different species of insects acting as a growth disruptor. It stops the development of pests and sterilizes adults, so they won’t be able to lay more eggs. Another valuable element making the neem oil spray so praised amongst gardeners is Nimbin. This compound is highly antifungal, meaning it could be used as a treatment against parasitic fungi like powdery mildew on plants. Due to its waxy properties, the oil can easily cover and suffocate pest eggs, which makes finding a better solution than neem oil insecticide very difficult. But where to buy neem oil insecticide in the UK?
You will find this useful if:
- You are a beginner gardener;
- There are fungi on your plants;
- You are dealing with an insect infestation in your garden.
What you need to make your own neem oil spray for plants
When shopping for neem oil, make sure you are buying a cold-pressed product, which still has Azadirachtin in it. Some of the products out on the market don’t contain Azadirachtin, in which case you can just use olive oil with the same success.
- Neem oil (with Azadirachtin) – 2 tablespoons;
- Soap – 1 tablespoon;
- Water – 2 litres;
- Mixing container (transparent);
- Garden sprayer – 2L (or bigger, but you should increase the dose).
How to mix neem oil for plants
Now that you have everything you need to make your neem oil spray, we can begin explaining how to properly mix it.
- Add two tablespoons of neem oil to your water.
- Add a tablespoon of soap.(use soap with no additives for better results)
- Mix the substance and pay attention to how quickly the oil rises to the top of the container.
- If the oil doesn’t start forming a layer at the top of the container within a minute, add some more soap.
How to apply your homemade neem oil insecticide
Give your sprayer a good shake before using your product. Spray on a small area and wait for at least 12 hours. If there is no damage to the leaves, you can proceed with treating your plants.
Spray from top to bottom and don’t forget to coat the underside of the leaves, as well. The good thing is that unlike the homemade pepper spray, this neem oil solution is not toxic to pollinators. Only insects that chew on your plants and their eggs will be affected.
Always test-spray a small area, before coating every plant. And as with other plant pesticides, it is best to apply it early in the morning or in the evening, when the temperatures are low.
