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!
