Dyna-Gro’s pure, organic, cold pressed Neem Oil comes directly from the seeds of Indian neem tree. Concentrated, Pure Neem Oil goes 66% further than the 70% diluted solutions. The 8 ounce bottle makes 8 gallons of solution.

Pure Neem Oil leaves a natural shine on leaves without clogging stomata that leaves need to take in carbon dioxide and release oxygen and water vapor essential to the basic functioning of the photosynthesis process. Many of the glossy leaf polishes, which give an unnatural appearance to leaves, actually interfere with these natural transpiration processes.

  • In India, products from the neem tree have been used for thousands of years for a variety of applications including their horticultural and medicinal benefits.
  • Recommended Crops: All plants and trees.

Instructions & Application Rates

  • Neem Oil may be applied as a foliar spray. Mix 1½ Tsp. Per quart of water (1 oz./gal.), plus ½ tsp. mild liquid dish soap per quart of water (2 tsp./gal.) as an emulsifier. Shake well.
  • Use once every 2 – 4 weeks. Apply early morning or late afternoon. Do not apply Neem Oil in direct sunlight. It might cause leaf burn. Always spot test plants first for sensitivity to sprays.
  • Spray the diluted solution generously on all leaf surfaces, including the undersides.
  • Neem Oil may solidify at cooler temperatures. Store above 65° F and below 95° F. If oil thickens, place the bottle in hot water.

    Great product. Goes a long way. Works on aphids, cabbage worms, and just about anything that will eat the plants!
  • neem oil

  • Owner
    This company is the best company I have ever done business with online. I use organic neem oil for my medical marijuana. It is an excellent organic systemic pesticide, an excellent preventative organic fungicide, and it leaves no residual when used properly. I ordered a gallon recently and it unfortunately arrived in less than desirable condition due to shipping. I contacted customer service, and Aneita handled the whole thing. No hassles and my replacement arrived packaged exceptionally well. I would recommend Greenhouse Megastore for every growing need. They're the best, from product availability, prices, and with the service they provided, I have to believe that they are second to none. Thank you again Aneita, and Greenhouse Megastore....
  • Great quality
    Would recommend because of great quality. Used on my tomatoes. Helped get rid of brown spots. Trying to help my peach tree get rid of curl fungus. If any tips to use with the neem oil please shoot me an email. Thanks
  • Neem Oil is the best organic pest control
    We have used Neem oil for a while on all of our vegetables and fruits, including trees. It's safe for animals and humans. We mix it with some Dr. Bronners liquid soap and BT (Dipel) for full spectrum insect coverage. We found a very good price with GM.
  • Does what I needed it to do
    My Meyers lemon tree had an infestation of bugs and the neem oil worked. I only had to use twice and they were gone. Plus I asked GreenHouse for some advice on the care of my plant and the customer service rep who replied was great and extremely helpful. Forget big do it all stores that lack great customer service and products in stock.
    I've used this as a foliar spray on my garden plants several times now, usually about 2 weeks apart, and it really does the job of getting rid of the white flies and gnats and all other little tiny insects that were on my peas and squash. Killed the bugs, left the plants happy and healthy and I still have more than half of the bottle of neem oil left! This stuff smells kinda funky but it works and that's all I asked it to do. PURE neem oil! Great price!!!
  • Seems to be working.....
    Been using neem for a few months on my apple, pear, and peach trees. It appears to be working (keeping the bugs from eating). I'll be curious how affective it will be as the fruit becomes ripe next month.
  • Neem Oil
    Worked excellent on potato bugs. Just don't use too much because it will burn the plants.
  • Excellent product for spider mites
    Very nice product, I used it in my indoor garden, I got rid of millions if spider mites after 3-4 treatments, it was amazing.. I am growing green chillies in my basement.
  • Fire blight
    Nectarine tree was hit with what I believe (from descriptions in books and I-net articles) was fire blight. All fruit fell off as well as foliage. Bark split and sap ran freely from wounds. Bark took on a burnrd look. Literature I read said nothing is known to be effective against this disease. I tried Neem applications each two weeks for two months. Next Spring we got good growth and fair fruit production. I use Neem each three months to keep the blight under control. Now I spray all of my trees, vegetables, roses and evergreens at least three times over the year. Anyone have any experience with Fire Blight?
  • Neem Works
    Works well on the devil squash bugs!
  • Did the trick on aphids....
    Pure Neem Oil works great on aphids. I have used it on trees and rose bushes and it has eliminated them completely and naturally.
    Five yeats ago I started using neem oil . If you read the instructions it reall y works. raise 15 acres of pumpkins - planted in JULY and the bugs and fungi are established at that time . Not one squash bug so far this year - no borers - and if you raise vine crops you know how bad they can get. None - not any - zero. IT WORKS- YOU JUST GOT TO BE SMARTER THAN A BUG TO USE IT. Safe enough to brush your teeth with.
  • Neem Oil
    The 100% Neem Oil I ordered from Greenhouse Megastore was exactly as advertised, very pure and great for use in soap and lotion making.
  • Reeeeally stinks.
    This product smells something terrible. It smells like rotting vegetation. Really really not advisable to apply product to plants in the bedroom, as it really stinks up the entire room and makes going to sleep awfully hard. On another note, we have noticed a slight decrease in the problematic gnats. This could also be due to the fact that we water our plants less frequently now.
  • Best Organic
    An excellant natural product for dedicated pest management regiment....
  • neem oil works
    I brought one of my outdoor plants indoor for the winter, and ended up with a sever aphid infestation. I bought this concentrated neem oil, it is a very strong concentration, and looks like i will be able to get alot out of this container. it comes with directions on the bottle, and is easy to dilute and spray. After applying, i was able to see a decrease in aphid activity after about 5 days. now 4 weeks later, most of the aphids are dead, but my plant is still damaged and sick. I am satisfied with the product anyways, i think it would have been a lot more helpful if i had used it before the aphids really went to town on my plant. this stuff works, and i feel better about using it because it is all natural, and not a chemical.
  • Not a good product. Will not use again.
    This product did not work in my garden. I was told that it would repel grasshoppers in my beans and okra. It did not!!! I went out the next day and there were more grasshoppers, I think it actually attracted them. I will not buy this product again, and I hope that you will seriously consider another product if you want to get rid of garden pests. I sprayed twice with neem oil and it did not work.
  • Excellent product
    This oil works great. Used it to get rid of whiteflies in my greenhouse and the problem was solved instantly.
  • Less bugs
    I recently bought neem oil and couldn't wait to try it. insects have been happily eating my broccoli and cabbage leafs. I sprayed the oil per instruction and in less that a week I have seen a tremendous reduction in chewed leafs and evidence of the nasty chewers. I am looking forward to having a full growing season to see the results.
  • Mixing
    It is really hard to mix this product with dish washing detergent. Need to use warm to hot water first then mix little by little.
  • Seemed to work
    I purchased the Neem oil for control of grasshoppers. Shortly after starting to use it the problem had diminished considerably and only a few remain at this time.
  • So glad I ordered!
    I am very happy with the neem oil I purchased from Greenhouse Megastore! I was having a major problem with lilac root weevil, and after learning that I needed a systemic pesticide to take care of it, I bought a bottle from the local garden supply store. However it only treated three bushes, and at that price I didn't feel as if I could afford to do them all. Wanting to go organic anyway, I searched for alternatives. That's how I found out about neem oil. Further searching led me to Greenhouse Megastore, which seemed to have the best price and the best product, so I ordered. I would like to say that it has worked far beyond my expectations (my eight lilac bushes never looked better!) --- and it doesn't smell nearly as bad as I was led to believe! It even worked with squash bugs!!!! I love the fact that it is good for the soil, and even for the skin, so I don't have to worry about harmful effects on me, my family, pets, or the beneficial microbes in the soil. Thank you for a great product!
  • Not living up to its claim
    I have used this product (Neem oil) as directed on the packaging twice (one week apart) on my cucumbers, green beans, and zucchini to repel cucumber beetles. The beetle numbers have decreased, but the beetles are still present. The plants are still suffering.
  • good product
    it really did help kill the squash bugs in my garden, not all but quite a few.
  • Seems to be pure
    I think I have finally found pure neem oil. The other stuff that I had smelled nice, but had other things in it & didn't stop very many things from eating my vegs
  • Winner! Winner!
    Even after reading all the positives about this product I was still skeptical. After 1 month of use I know I will never be without it in my organic garden. Exceptional results and so easy to use. Highly recommended!
  • 1st time user of Neem
    My tomatoes became infested with whitefly so I looked for an organic remedy. I am so happy I found Neem...I used it 2ce so far and it is working so effectively and gently, I don't think I'll need to do another application, but if so, my plants love it anyway so it can only help. I love the idea that Neem is natural, and that it works by coating the tiny bugs and also affects their eating and reproduction. What else can I use Neem for, it would be interesting to know. Thanks.
  • Good garden product
    Helps keep plants leaves shiny and helps keep pests away. Easy to use. Handy size will last quite a while.
  • Neem Oil
    Took care of all the bugs except Japanese beetles. Plants look much healthier.
  • YES!!!
    I tried other natural/organic brands and this is the only product that FINALLY got rid of the spider mites on my plants!
  • Excellent for the neighborhood gardener!
    This is only my second year of vegetable gardening, and though it is the middle of June; my plants look much better and are noticeably bigger than they were this time last year. I never knew I would come to recognize so many different species of insects; as I became a quick study last year! After being told about 'Neem Oil;' and using it as recommended, I have more time to enjoy my garden than I spend researching what this bug and that bug will do to my garden. In fact, they are no where to be found. Now I may have a bigger problem; where to store all my vegetables this fall/winter.
  • worth every cent
    i have just used it once so far and it has worked very well. great stuff.
  • Excellent product
    The Neem oil was delivered very quickly and the quality was excellent. It did just what it supposed to and did it well
  • Excellent Organic Bug Control
    My plants were dying from bug damage. Started using Neem Oil, and they recovered, and flourished wonderfully! EXCELLENT!
    My plants look a lot better I am happy
  • Great Product
    I had looked locally for this product without any luck, finally decided to order on line. This site had a great price and shipped fast. The Neem oil has worked great on aphids, powdery mildew and scale.
  • Super Organic Orchid Insecticide and Fungicide
    This product is incredible! So far it has solved our scale and roach problem in our greenhouse. Have not seen any pseudobulb rot lately or crown rot in the phals. I do keep fans going most of the time but roaches were eating roots and scale was starting to spread and Neem nipped it in the bud! (No pun intended!)
  • speedy and prompt
    received in a very timely manner. excellent seller and will do business in the future. thank you, gary
