Dealing with Surface Tree Roots When Installing Lawn Curbs

Introduction

Fruitless mulberry trees often push large roots to the surface, complicating curb installation. Cutting roots risks tree health but may be necessary.

Assessing the Risk

• Mulberries are fast-growing, soft-wooded, and prone to surface roots.
• Roots seek water; deep watering encourages deeper rooting.
• Cutting a 10-inch root will likely kill the limbs it supports.

Options

1. Cut Roots Back: Prune roots to 4–5 feet from curb. May save limbs if enough roots remain. Water deeply afterward to encourage new feeder roots.
2. Remove Tree: If shade isn't essential, removal eliminates future root conflicts.
3. Adjust Curb: Curve curb around major roots if possible.

Conclusion

Weigh the tree's value against hardscape needs. If cutting, minimize wound size and maintain deep irrigation to support recovery.
