Maple Root Concerns and Hybrid Poplar Stump Control

Two questions: maple foundation risk and killing hybrid poplar roots.

Maple Roots & Foundations

• Japanese maples: 6-25 ft spread, roots ~1.5x canopy width.
• Sugar maples: 30-45 ft spread.
• Roots rarely damage foundations; limbs may rub houses (prunable).
• Prune in fall after leaf color change to control size.

Killing Hybrid Poplar Roots

After cutting: immediately paint stump with undiluted Roundup using a cheap brush. Herbicide translocates to roots. If sprouts appear, wipe foliage with Roundup. Caution: Roundup kills any green plant contacted.
