What can I plant around my septic tank?

How do I protect my septic tank from tree roots?

Copper Sulfate

Copper sulfate is effective at killing roots growing in drain fields and septic tanks. Not only does copper sulfate kill already existing roots, but it also discourages the growth of new roots and keeps growing roots out of septic systems.

What kills roots in septic tanks?

Flush 2 pounds of granular copper sulfate down the toilet for every 300 gallons of water that the septic tank holds. Copper sulfate kills and dissolves tree roots as they absorb the tank's water. After entering a tank, the majority of copper sulfate settles in tank, and little passes into the leach bed line.
