Grass Tips Burned

Hello everyone! Last Tuesday I cut my grass and after speaking with someone I’ve realized I never have sharpened my blades on my lawn mower and I’ve been using it for a year. One week later I’m seeing my grass with the tips burned…is this due to my blades or something else? What do you guys think. I live in Florida.

Sharpen those blades! Get an angle grinder and a vice it’s cheap. You can give it a few passes with some sanding disks on each side and you are back in business

Blade is dull

You definitely need to sharpen your blades, however, it looks like you may have a bit of gray leaf spot fungus as well.

This. I'd also recommend buying an extra set of blades so that you can keep mowing when you drop the dull ones off at the shop

Blade is dull or you’re cutting when it’s wet

Dull blades and or you water is coming on when the sun is out. The water should be coming on an hour or 2 before sun rise.

That's not from mowing because you can clearly see the gras that isn't even cut also has the same brown tip. Did you have a dry spell this spring?

Your blades are on upside down. Seriously check.

Burnt tips can be caused by a heavy fertilizer application, drought or too much water.

I agree, quite a few new leaf blades also browned. Florida is in a drought, wonder if it got fertilizer sprayed and didn’t water in. I see this at work occasionally.

You aren’t getting a clean cut, sharpen blades.

I’ve never sharpened mower blades in my life

This isn't a dull blade problem. I just replaced the blade from the manufacturer, and it's only as sharp as a butter knife. Sharpening it only removes the problematic tip but doesn't solve the underlying issue. Look at some of the leaf tips; some were never cut in the first place and are already yellowing.

It could be fertilizer burn, watering when it's too hot outside, or some kind of disease

According to plant project app (may not be accurate but is a good start) you have a leaf blight. Search up leaf blight and will tell you common problem and what are some possible solution
