Dibbs Seed Copper Sulfate Powder Pentahydrate Fertilizers 5 Lbs

This is the most economical way to keep the sewer pipes clear of tree roots. The product will kill roots without harming the tree. I need annual application because there is a large oak tree 10 feet from my pipe connection. Best time to apply is in the spring .

Product came packaged in multiple bags with padding included which helped the copper sulfate not spill everywhere. I purchased this to use for equine hooves and tree stumps. 100% recommend. good quality and fine dust in consistency. I will be buying more!

I used it in my planting pots to curtail mold and mildew which was a very big problem last year. I sprinkled it in with my soil before a planted and my plants are three times the size of the ones I didn't use it on. they are very healthy very green. Great product!

Works great to kill root buildup in and around septic system. Also worked great to kill the weeds around my AC unit.

cheapest source of copper i could find. can cover a lot of grow space with this. i apply 50 grams per 1,000 sq ft

Product arrived in secure packaging and I feel like I'm already seeing progress in the stumps I used it on after only a few days. Great value compared to other available products.

Great packaging and quick delivery!

Dissolves quickly. I am using this to get rid of black mold. It will prevent it from growing back.

This is great copper sulfate!

Recently purchased for root control in septic/drainfield so it is too soon to see any results. However, the value, shipping and packaging were outstanding! Will update accordingly.
