From How Important Is a Perfect Lawn When You’re Selling Your Home? [New York Times 2014-08-06]:

“The simplest way to not screw up your lawn is to set your mower as high as it will go and make sure your mower blade is very sharp, so you’re cutting the grass blade, not tearing it. When you cut it lower, the grass doesn’t have the leaf material to do the photosynthesis that it needs to sustain itself. … The best time to take care of our lawns in northern climates is in the fall: Labor Day to Halloween. Any grass seed you put down at that time should do fairly well.”

Mary Thurn, research support specialist with the Cornell Turfgrass Program, demonstrates how she uses the [make and model] drone to get an aerial view of turf research plots.

Above: Mary Thurn, research support specialist with the Cornell Turfgrass Program, demonstrates how she uses a DJI Phantom Aerial UAV Drone Quadcopter with GoPro camera drone to get an aerial view of turf research plots.

Cornell Turfgrass Program researchers are employing a drone this summer to take aerial photos of their research plots.

“Of course we still collect data. But with the bird’s-eye view, you can see things that you can’t see readily — or at all — from the ground,” says research support specialist Mary Thurn. “We can also send pictures to collaborators who can’t visit the site in person and they can still see treatment differences for themselves.”

Drones may prove to be a practical tool for turf managers, too, Thurn points out. For example, a golf course superintendent could fly one around the course to spot stressed grass that may need water, fertilizer or pest management attention before the problem gets too severe.

Aerial images can show differences not readily visible at ground level.

Highlights for week of July 14 include:

  • ForeCast: More widespread heat stress last week. Expect high heat stress early in the week and with prolonged leaf wetness lots of foliar disease pressure. Cool temps usher in the weekend and what appears to be a shift in the pattern to cooler than normal. Visit the ForeCast website for the latest turf-related weather.
  • Summer patch samples starting to flow in to diagnostic labs.
  • Have a history of Summer patch? Work to alleviate compaction, but also be sure your manganese applications are consistent
  • Use wetting agents to relieve localized dry spots.
  • Mild conditions in May and June, with timely rain for most people, may have masked annual bluegrass weevil activity.

Highlights for week of July 7 include:

  • ForeCast: Widespread heat stress throughout the Northeast. Widespead 1- to 2-inch rainfall, but drought stress still an issue with shallow-rooted turf. Visit the ForeCast website for the latest turf-related weather.
  • Crabgrass is surging. Read about best ways to control larger plants.
  • Beginning to see anthracnose problems, particularly on annual bluegrass putting surfaces that have structural problems of low-light, high surface organic matter, and management issues — too lean on nitrogen and too low mowing heights.
  • Football (Americans call it soccer) players prefer natural turf, study finds. A selected group of professional players, representing professional soccer players in North America believe that there is an increased risk of injury, specifically non-contact injury, as a result of training and competing on synthetic turf (3rd generation infilled) compared to natural turf.

This week:

  • Great weather start to summer
  • Alternative broadleaf weed control
