  • Mealybugs are a type sucking insect that can sometimes appear out of nowhere. If one or two mealy bugs gather on the plants, the Neem oil can be nipped in the bud. If there is a more extensive infestation of mealy bugs, a Neem oil solution is used to spray the plant as and when required.

However, reckoning on the severity of a plant’s problems, the concentration and frequency of application of Neem oil may be increased or decreased. 

Pros & Cons Of Using Neem Oil On Indoor Plants – 

Pros of using Neem oil:  

  • The good thing about using Neem oil solution is that the plant is not affected by the Neem. It will ensure the whole plant is protected, and the answer cannot even be washed off if it rains. 
  • It adds a sheen and luster to the plants without having any damaging effects like most chemical-based plant polishers do. 
  • Neem oil kills various insects, including aphids, mealy bugs, whiteflies, Japanese beetles, leafhoppers, fungus gnats, and other garden pests like spider mites and nematodes.  
  • Neem oil can also kill fungal diseases like powdery mildew, black spot, scab, anthracnose, and leaf spot.  
  • Insects do not become as resistant to Neem oil pesticides as they can to other chemical pesticides. This means that Neem oil remains effective even after repeated applications. 
  • Nematodes are challenging to manage and might be very destructive to plants. Neem oil has been shown to provide reasonable control over root-knot nematodes — one of the most dangerous ringworms. Neem oil works by preventing larvae from hatching.  
  • While traditional chemical pesticides can harm earthworms, Neem oil has the most alternative effect by encouraging earthworm activity. Earthworms are beneficial to garden soil to boost its fertility; therefore, the application of Neem oil does not interfere with the activities of the earthworms within the earth. 

      Cons of using Neem oil: 

  • Neem oil should not be applied to plants like caraway, basil, cilantro, marjoram, dill, parsley, oregano, or thyme. Use caution in spraying the Neem oil onto plants with delicate or wispy leaves, such as peas, arugula, lettuce, and spinach, as this can harm the foliage. 
  • No matter the type of plant being treated, Neem oil can damage the plants by burning their foliage. Do not use on recent transplants ordeportedd otherwise stressed plants. 
  • If used too frequently after the plant has been treated, Neem oil can harm plants by coating them in an exceedingly thin layer of fat and thus choking the pores on the leaves, which are critical for photosynthesis, transpiration, and oxygen release. 
  • Spraying Neem oil on plants in direct sunlight might sometimes result in the leaves curling up, eventually making them burn. Caution must always be maintained to avoid direct sunlight as a safety measure.
