Low Down on Neem Oil For Plants

Neem oil is fantastic if you purchase the correct kind and use it properly. Most of the time when I hear someone complain that Neem oil didn’t work for them it is because they were misguided.  So, here is the low down on Neem Oil For Plants.

First of all, I should state that Neem oil is used on plants to get rid of a slew of nasty critters.  I would state if you were to only be able to purchase one pest removal – it should be Neem Oil.

What Product to Purchase

You want to purchase 100% pure cold-pressed Neem oil.

  • Look for the active ingredient Azadirachtin.
  • Be sure it is 100% cold pressed Neem oil.  This is the only brand I purchase!
  • There are less expensive options but be sure to look for items above – you are wasting your money.

Why Buy Neem Oil?

Literally, I can’t give you every purpose to use Neem Oil for.  However, I can say it is used for everything from plant pests to beauty products.  It stops pests in their tracks without hurting beneficial insects. It is my go-to product for anything plant, tree and vegetable garden related.

It Is Organic

  • No harmful chemicals
  • Doesn’t harm the good insects like bees and ladybugs
  • Pet safe

What Plant Pests Will It Control?

So, so many and many.  Here are a few I have used Neem oil on that I couldn’t possibly list every critter that Neem oil will protect you from.

Below is a list of the popular critters.

• Lily Beetles
• Japanese Beetles
• Spider Mites
• Black Flies
Fungus Gnats
• Tomato Hornworms
• Corn Earworm
• Whiteflies
Cucumber Beetles

Used as a Fungal Spray

Powdery Mildew On Plant
  • Kills bacteria and fungus growing in wood mulch. 
  • On all plants for all forms of mildew

Always Test First

  • Mix up the recipe below
  • Test spray a few leaves to be sure the plant can handle it, wait for 48 hours.
  • Spot test plants, just to be sure.  Don’t chance using the product on a new plant without testing it first. 

Neem Oil Recipe


  • 100% pure cold-pressed Neem oil ( 2 Tablespoons)
  • Warm Water (1 Gallon)
  • Spray Bottle or Sprayer
  • Dish Soap (1 Tablespoon)

Spray during early morning hours or during the coolest part of the day. Neem oil can heat up in the hot sun and burn plants. It is best used during the coolest portion of the day.

Some Things to Remember

• Mix a batch and use it.  The mixture loses potency when premixed and stored

• The mixture has a smell until it dries

• Temperatures below 70 degrees the Neem oil will thicken.  Place bottle in a warm water bath to loosen

• Spray early morning or early evening

• Use every 10 days unless it rains then reapply sooner.
