White tips on Grass

[MJStrain]

Sometimes when I cut I've noticed that the tips of the grass turn white. What is causing this?:dizzy:

[Lanelle]

Dull blades. They shred the grass blade instead of cleanly cutting it. The damaged part dies and turns color. If you are cutting a full day with a mower, put newly-sharpened blades on each day and see if the problem disappears.

Dull blades will also help burn the lawn in dry conditions.

Look at the tips closely. Are they frayed or are they cut pretty clean? If they are frayed, it's a dull blade. If it's not, it is fert burn. Probably a liquid application to a stressed turf.
