Is a mulching mower better than bagging?

For most home lawns, mulching wins. It returns nutrients to the soil, saves bags and time, and cuts down on fertilizer. Bagging still has a place in a few situations.

How mulching works

A mulching blade has extra curves that lift and recut clippings inside the deck. The fine pieces fall between the grass blades and disappear within a few days.

When mulching works best

• You mow often enough to remove no more than a third of the height
• The grass is dry when you mow
• Your blade is sharp, so clippings are cut cleanly

When to bag instead

• The grass got very long and clippings would smother the lawn
• You’re collecting material on purpose for compost or garden mulch
• Weeds have gone to seed and you don’t want to spread them
• A lawn disease is active and you want to remove infected leaf material

Switching over

Many mowers take a mulching blade or plug kit. A sharp blade matters more than the brand.
