Poplar Windbreaks vs. Lawn Health: Root Competition, Shade, and the Inevitable Trade-Off

Western Canada. Tower poplars + northwest poplar for windbreak. Lawn was good, now patchy yellow/green. Aerate, fertilize, etc. Asks if roots compete, can do more, reseed to drier mix?

Root Competition & Shade

Likely cause. Aerate every other year, fertilize, pH 6.5, deep infrequent water, reseed. Woodlands and pastures don't coexist—one thrives, other suffers.
