What Plants Not To Use Neem Oil On
Neem Oil: Exceptions for Cold-Sensitive Plants
While neem oil is generally considered safe and non-toxic for most plants and crops, there are a few exceptions to keep in mind. Firstly, it is important to note that neem oil should not be used on cold-sensitive plants, such as tropical species or plants that are susceptible to frost damage. Neem oil may exacerbate their sensitivity to cold temperatures, resulting in additional harm.
Protect Plants from Neem Oil Sun Damage
Secondly, avoid using neem oil on plants that are in the sun or under heat stress. The oil can potentially magnify the effects of the sun’s rays, causing burns or damage to the leaves. It is advisable to apply neem oil either during the cooler parts of the day or in the evening when temperatures are lower and the sun is less intense.
Ericaceae family plants sensitive to neem
Thirdly, plants that belong to the Ericaceae family, including blueberries, azaleas, rhododendrons, and cranberries, can be sensitive to neem oil. These plants have special adaptations that make them less tolerant of certain oils, including neem oil. It is recommended to test a small section of the plant before applying neem oil to avoid any potential harm.
Caution: Neem oils potency harms seedlings
Lastly, young or tender seedlings may not handle neem oil well, especially if it is applied in high concentrations. The oil can be too strong for delicate plants, potentially causing burning or stunting their growth. It is advisable to dilute neem oil properly and apply it carefully, following the instructions on the product label and considering the specific needs of your plants.
