Michigan State University turfgrass researcher Thom Nikolai, Ph.D., working in partnership with scientists at Scotts Miracle-Gro, have a new fall regimen for obtaining a healthy lawn without backbreaking leaf raking.
Over years of study, Nikolai found that turf was healthier when homeowners mowed fall leaves back into the lawn instead of raking. Recycling the fallen leaves back into autumn lawns saves time and money, adds nutrients, speeds spring greening and reduces weeds.
?EUR??,,????'?????<????????In the fall 2007 leaf mulching study, I discovered yet another way to encourage decomposition: fertilizing after the mulching process,?EUR??,,????'?????<???????? said. Nikolai. ?EUR??,,????'?????<????????We tested up to 18 inches in leaf litter topped with Turf Builder or Turf Builder Winter Guard and showed that the fertilized areas had significantly less leaf refuse in the spring.?EUR??,,????'?????<????????
?EUR??,,????'?????<????????Partnering with Dr. Nikolai on this research is an exciting way to develop innovative products for lawn care,?EUR??,,????'?????<???????? said Jeff Garascia, Ph.D., vice president of research and development at Scotts. ?EUR??,,????'?????<????????This connection between leaf mulching and fertilizer is integral to our continued efforts to offer sustainable products that further enhance the already acknowledged environmental benefits of turf.?EUR??,,????'?????<????????
