About Neem Oil And Plants

Neem oil is a wondrous product indeed. The neem plant is native to India and many countries on the African continent. Thanks to the active ingredient in neem oil, Azadirachtin, the oil of this medicinal plant thwarts fungi, insects, bacteria, and disease.

Spray a diluted amount of neem oil on indoor plants to repel mosquitoes, prevent infestation of pests and their eggs, and to promote a plant's health and wellness. Additionally, neem oil has proven beneficial for human health and beauty as well.

In most instances, it is wise to apply neem oil to plants every two weeks as needed to curb insects, fungus, bacteria, and disease. However, depending on the severity of a plant's problems, the concentration and frequency of application of neem oil may vary.

Feel free to create a homemade fungicide or insecticide for your indoor plants using neem oil. Or, you can choose from a selection of quality neem oil products for indoor plants.

For anyone who desires a natural, environmentally-safe product to use on indoor plants, neem oil is a fantastic solution. Neem oil has been trusted as a safe, effective insecticide and fungicide.

Most plants are tolerant of having an application of neem oil placed on their leaves, stems, and surrounding soil. However, plants that have been recently transplanted, are low-moisture plants, or are young and still not established may develop damage to their foliage.

Take care when spraying plants with neem oil and do a test patch to ensure it won't cause any adverse effects. Also, make sure to always dilute neem oil because it is incredibly strong. A concentrated amount of neem oil could be deleterious to indoor plants.

Encourage your plants to fend off insect pests, powdery mildew, root rot, and other common problems. Spray down the soil of indoor plants with neem oil so the roots can soak it up and deter disease and parasites. Neem oil is non toxic and doesn't leave harmful residue.

Can I Spray Neem Oil Indoors?

It is safe to spray neem oil on plants indoors, but ensure the ventilation in the space is good. Whether using a concentrated or diluted amount of the oil, the strong odor can trigger light respiratory irritation if breathed in. Apply a light coat of diluted oil to be safe.

If neem oil is ingested by children, pets, or adults, it can cause harmful reactions like nausea, diarrhea, vomiting, and even seizures. Caution should be taken with spraying neem oil, as contact with the skin can cause a rash, itching, or redness.

Always follow manufacturer directions when applying a neem oil product. It is best to use as much as needed for a safe application. Know before you spray whether you are working with a ready-to-spray formula or a concentrated oil with a high amount of Azadirathacin.

Neem oil is a desirable alternative to products with potentially toxic ingredients, as neem is natural, non toxic, and biodegradable. The oil is safe for humans and animals. However, do not allow neem oil or spray to make contact with skin, eyes, or ingest or breathe it in.

How Do You Use Neem Oil On Indoor Plants?

If you plan on using neem oil on indoor plants, you'll most likely use a concentrated oil that you dilute or a ready-to-spray option. Coat the tops and undersides of all leaves of any plant you want to protect against bug infestations with a thin layer.

Be cautious not to spray neem oil on plants that are a bit stressed, show signs of a lack of water or sunlight, or poor soil. Also, take care when applying neem oil to plants that don't like a lot of moisture, as this can cause damage down the line. Less is more with neem oil.

Avoid applying neem oil to indoor plants that reside in a sunny location. Instead, allow them to get a treatment while placed in a darker area for a few days. If you don't see any visible problems with pests, fungi, or disease, it's fine to occasionally spray plants with neem oil.

Spritz neem oil on the leaves of plants, the top layer of soil, and any areas where you see signs of problems. If you discover any signs of insect eggs, holes in leaves from chewing or burrowing, or sticky residue, it's time to reach for neem oil. Apply the oil every two weeks.

In Closing
