Killing Red Tip Shrub Roots Permanently with Herbicide

Effective Root Elimination

Owner wants to dig up red tip shrubs (Photinia) near the house and ensure roots don't regrow.

Recommended Product and Method

• Herbicide: Roundup (glyphosate) or equivalent non-selective herbicide.
• Application: Fully coat leaves to point of runoff while plant is actively growing.
• Mechanism: Translocates to roots, killing entire root system including fine roots.

Timing and Follow-Up

Apply in spring or early summer when foliage is full. Wait 2–3 weeks for full translocation before digging. This prevents resprouting from root fragments.
