That’s a harmless fungal growth commonly referred to as “powdery mildew”.  It’s most prevalent during periods of high humidity and cool nights. It also tells you there is a high nitrogen content but it is completely harmless to your lawn. While a fungicide is available to treat severe cases, we at BAM! Green have never seen a case severe enough to warrant a fungicide treatment. What to do? Give it a few days — weather conditions usually change. The grass blades will continue to grow and the infected blades will simply get cut off by your lawn mower. Powdery mildew is also a common problem in many tree species.

The striping effect is achieved using a weighted roller mounted behind the mower. The roller simply flattens the grass. Each row the mower cuts is flattened in alternating directions. By flattening the grass, more of the green part of the blade is exposed. When looking at the lawn, the grass that has been flattened away from you appears as the greener stripes because you are seeing more of the blade side on. The grass that has been flattened away from you appears lighter because you are seeing more of the tips of the blades. The effect is far more dramatic from the air which is why golf courses on T.V. look so amazing when you see them from the helicopter fly over, or when you see sports fields from the Goodyear blimp. Where artificial turf is used, a metal broom is used to comb the turf in one direction or…

Mowing right helps the lawn to thicken up, increase in density, thrive while other lawns are suffering, reduces the need for watering, and increases stress resistance. Mowing incorrectly, even once, stops all of this from happening. Poor mowing practices don’t simply stress the lawn, it actually damages it. There is a difference. On the front of our lawn sign that you’ve been keeping near your front steps, is a handy ruler for your convenience whenever you cut your lawn.
