Captain Jack's Neem Oil Organic Concentrate is a good value for the money and so easy to use. Safe to use on ornamental and edible plants. I add the concentrate as directed to my automatic Captain Jack's sprayer. I have used it this year on my clematis that keeps having eaten spots on leaves by little black larvae on the undersides of the leaves. I think they may be the same larvae that ate up my Kimberly fern practically overnight last spring before I had the chance to treat. I have sprayed Captain Jack's Neem Oil every 7-14 days on and under the leaves to kill the eggs/larvae two or 3 times this spring to make sure my clematis survives their attack. Yay! Currently no longer seeing any newly eaten leaves and/or larvae after treating with Captain Jack's. I check it daily when I water. Have removed all affected leaves to be sure they are gone. Highly recommend this organic product on ornamental and edible plants. It works!!

Good product %26 good value!

Each fall before bringing my potted plants inside for the winter, I use neem oil to spray potted plant foliage and then use a soil drench in the pot to make sure that I don't bring any insects inside my home. I like that this product has a greater % of neem oil in the concentrate than competitors. A small amount does the job so that a lot is left for the next spring when I spray my in-ground crepe myrtles to kill aphids and those white fuzzy scales which make the bark turn black. Without the aphids, there is no sticky honeydew to attract ants or to make lawn furniture under the trees sticky.

Greenery's Best Friend!

This Neem Oil Concentrate I purchased on sale, good price, quick and easy to mix instructions included for multiple size sprayers - works like magic on protecting your plants and young trees. I've had trouble this year with lanternflies EVERYWHERE in my yard, and they can do some damage! After spraying this - not an issue!
