When To Leave Grass Clippings in Place

Before leaving grass clippings on the lawn, it’s importantto understand the difference between a mulching mower and a traditionaldischarging one. Every mower has a discharge chute that allows grass clippingsto escape, either into a bag or the lawn, but mulching mowers cycle theclippings through the blades again to create a finer shred that is ideal formulching.  

Leaving discharged clippings in place can serve the samepurpose as mulch if they aren’t so long or clotted that they completelycover the grass and impede growth. The benefits of leaving clippings in place(mulched or otherwise) include: 

Soil Nutrient Retention 

Mulching is an important part of lawn health improvement, asthe clippings provide water and nutrients to the soil. The organic matterdecomposition feeds the earth and the grass’s new growth with essentialnitrogen, phosphorus, and potassium. The process supports the microbial lifebeneath the soil’s surface, fostering healthier grass and stronger rootsystems. 

Moisture Conservation 

As with woodchip mulch around the base of trees andshrubbery, grass mulch supports moisture retention by slowing evaporation fromthe top layer of soil. This may be especially beneficial to grasses indrought-prone areas and can reduce the costs and time spent on watering thelawn. 

Controlling Thatch 

Mulching boosts microbial activity in the soil, which isessential to controlling thatch development. Proper mulching can also aid inthatch prevention by allowing regular mowing and avoiding overapplication offertilizers. The only exception to mulching improving thatch is when the grassmown is excessively long because it can be tough and stalky, breaking down tooslowly to provide nutrients without suffocating the growing blades below. 

Reduced Effort 

Clippings provide health benefits to the lawn, andhomeowners can enjoy less work with this method. Bagging, blowing, and rakingclippings can take serious effort, and leaving them in place eradicates theneed for this extra work. 

When Not To Mulch a Lawn 

While it has many benefits, mulching a lawn with grassclippings can do more harm than good in some cases. For excessively long grass,leaving the clippings in place can cover too much of the new growth to allowfor adequate light and nutrient exchange. Longer or wet, clumping grasses alsoadd excess strain to mulching mowers and damage the blades or motor overtime. 

It is also better to bag clippings when signs of disease arepresent to avoid spreading the issue. Grass cut toward the end of summer, whenthe first autumn leaves fall, may also be better off bagged to prevent leafpile-up.
