The "Sissoo" Secret: Why Some Phoenix Trees are Ruining Your Hardscape

If you have a beautiful, lush tree in your yard that seems to be growing faster than everything else, you might have a Dalbergia sissoo. While these trees provide incredible shade, they are becoming the #1 enemy of Phoenix driveways, pools, and paver patios in 2026.

The Silent Destroyer Sissoo trees have aggressive, shallow "runner" roots. We’ve seen these roots lift heavy pavers, crack pool shells, and even invade sewer lines 30 feet away from the trunk. At Pinnacle Tree Service, we specialize in "Sissoo Management."

What You Can Do:

1. Root Pruning: If caught early, we can prune roots to save your hardscape without killing the tree.

2. Strategic Removal: If the tree is too close to the house, removal is the only way to stop the damage.

3. Chemical Mitigation: Simply cutting a Sissoo down isn't enough—the roots will send up "clones" all over your yard. We provide the chemical treatments necessary to ensure the root system actually dies.

Don't let an invasive tree cost you thousands in paver repairs. Call Pinnacle for a root-zone evaluation today!
