What Plants Not to Use Neem Oil On


Neem oil for plants is the most powerful natural pesticide available. It packs a punch that the majority of natural pest repellents just can’t duplicate. This makes neem oil a great alternative to chemical pesticides.

Its high potency might have you wondering if neem oil is safe for your plants.

For many plants, neem oil is completely harmless if used properly. But should you use it on leaf vegetables like lettuce and spinach? What about herbs such as cilantro, basil, or thyme?

Read below for guidance on what plants not to use neem oil on and how to prepare your own neem oil spray to protect your garden. 

What Is Neem Oil Used For?

If you find yourself asking “what is neem oil used for?” here’s what you need to know. Neem oil is a completely natural, non-toxic pesticide. It is one of the few natural pesticides that is strong enough to completely neutralize pests. This makes neem oil highly popular in the organic gardening community.

To deter pests such as spider mites and aphids, you will spray your entire plant with neem oil. The oil will then be ingested by any bug that chomps on your leaves. The active ingredient in the neem oil, Azadirachtin, will quickly work to disrupt the appetite and hormone systems of the pests. 

Once you begin using neem oil in your garden you will notice a rapid reduction in leaf-munching pests.

Can Neem Oil Kill Plants?

To answer the question of can neem oil kill plants, in most cases neem oil will be safe to use on your plants as long as you follow proper spraying protocol. But if you’re not careful, you can damage your plants with neem oil. 

It is important that you do not spray neem oil on your plants during the daytime when the sun is shining bright. Direct sunlight will cook the oil and cause the plant leaves to burn. Mature plants likely won’t die from it, but their growth could be stunted. Young plants and seedlings stand a much greater risk of perishing from the burn. 

To avoid frying your plants, spray them with neem oil in the evenings when the hot sun is no longer a threat.

You should also make sure that the plants you intend to spray neem oil on are tolerant to it. Most are, but not all.

Which Plants Don’t Like Neem Oil?

Neem oil for plants is an excellent alternative to chemical insecticides. But not all plants respond well to neem oil. Garden plants with delicate foliage are sensitive to neem oil and can get foliage burn even if you spray them at the right time. 

It is important that you know which of your plants not to use neem oil on so you don’t cause them unintentional harm.
