Sunflecks on shaded turfgrass: Good, bad, or of no consequence?

By Dominic Petrella

When we think about turfgrass shaded by trees we as researchers often focus on reductions in light intensity, reductions in the red to far-red ratio (R/FR ratio) along with other changes in spectral quality, competition for water and mineral nutrients, and alterations to temperature compared to full sun environments. However, another challenge for turfgrass plants under shade is exposure to sunflecks.
