Been using this on my sewer pipe for the past four years to keep the roots off. Before that, I used to call the plumber yearly. Review: EXCELLENT ROOT KILLER!! - Living in an older (1954) home comes with its perks and disadvantages. One disadvantage is long established trees and their root systems. Some trees and bushes will seek out any water source they can find; including sewer lines. After one instance of a several hundred $$$ for a plumber to clear roots out of the sewer line, I did research and found copper sulfate. Using about two cups of the large or extra large crystals in the main line once a month, I have never called the plumber again. . .20 years now. There are a couple of instances where roots have started to come up in the yard; growing new trees, UGH! Just dug out around the area enough to pour dissolved copper sulfate (1/2 cup copper sulfate in four cups water. . .takes a couple of days to fully dissolve), around the exposed root and POOF, a few days will render it dead. . .never to be seen again, WooHoo! ## Features - Briquette Size - Bulk - Hydroponic Approved - USA Made - 5+ MM Crystals ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01JH79LMY | | Best Sellers Rank | #75,280 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #88 in Beer Brewing Ingredients | | Date First Available | August 1, 2016 | | Is Discontinued By Manufacturer | No | | Item Weight | 10 pounds | | Manufacturer | Earthworks Health LLC | ## Product Details - **Brand:** Xnets - **Item Form:** Granule - **Item Weight:** 10 Pounds - **Manufacturer:** Earthworks Health LLC - **UPC:** 756519496970 ## Images ![Copper Sulfate Large Crystals 10lb Bag - Image 1](https://m.media-amazon.com/images/I/41QQqqlpyzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by A***R on June 28, 2025* Works.
