Managing Poplar Suckers: Let One Grow, Skip Root Cutting, and Accept Shade-Tolerant Groundcovers

Large poplar sends suckers through lawn, thinning grass. One sucker in good spot for a tree. Questions: (1) Will it become full-size? (2) Cut root to parent? (3) Will grass return if a few suckers grow?

Answers

1. Yes, full-size tree.
2. No need to cut—it grows faster attached.
3. Grass under trees is work. Poplars are high-water-use; grass dies from drought, not shade. Use shade groundcovers instead.

Cool-Season Grass Strategy

Grows fall–spring (full sun when leaves gone), stores carbs for summer shade. Limit summer fertilizer/mowing, pump water.
