WASHINGTON — Be sharp — don’t cut a wet lawn.

With all the wet weather, a warning is in order: Do not cut your lawn while the grass is still wet. Cutting a wet lawn tears the grass blades apart as opposed to cutting them cleanly, and that makes the grass much more vulnerable to injury when summer heat arrives.

So let the lawn dry out for at least a day before you mow — and don’t mow first thing in the morning, when the grass is wet with dew. If cut grass is sticking to your shoes, the lawn is too wet to mow!

It’s equally important to cut with a super-sharp blade. A dull mower blade tears the grass up just as badly as cutting when wet. If you haven’t sharpened or replaced your blade this season, do so before the next cut.

Cut sharp and cut dry in the spring, and your lawn will stay green and bright when summer heat settles in.
