Neem oil: Natural pest control for houseplants
What's the story
Neem oil is a widely-used natural solution for getting rid of pests in houseplants.
Derived from the seeds of the neem tree, the oil has been used in traditional agriculture for centuries.
However, its disruptive effect on the life cycle of insects makes it an ideal choice for anyone looking to go green.
Here's how you can use neem oil to keep plants healthy without synthetic chemicals.
Mechanism
How neem oil works
Neem oil works by disrupting the hormonal systems of insects, stopping them from growing and reproducing.
It contains azadirachtin, which is responsible for repelling and killing pests.
When applied on plants, it coats the leaves and stems, deterring insects from feeding on them.
This makes neem oil an effective solution against common pests like aphids, spider mites, and whiteflies.
Usage tips
Application methods
To use neem oil for best results, mix it with water and a few drops of mild liquid soap to make an emulsion.
Spray the mixture on affected plants every seven days till pests are under control.
Make sure to apply it on both sides of the leaves but don't do it during peak sunlight hours as it may burn the leaves.
Advantages
Benefits over chemical pesticides
Neem oil has various benefits over chemical pesticides.
It is biodegradable, meaning it decomposes easily in the environment without leaving behind toxic residues.
Further, it carries little risk to beneficial insects such as bees, provided it is applied properly.
This makes it a safer alternative for indoor plant care than regular pesticides which may be harmful to non-target organisms.
Safety measures
Precautions when using neem oil
While neem oil is generally safe for humans and pets when used properly, precautions should still be taken during application.
For starters, wear gloves to avoid skin irritation, and ensure good ventilation if spraying indoors.
Always test a small area first before full application, as some plants may be sensitive to oils or soaps used in mixtures.
