Being careful about how much to add is paramount. 

Mixing grass clippings into the soil is called mulching. If you have an existing problem with thatch it may be a good idea to check whether or not your soil needs the extra clippings. If you have a lot of weeds or dandelions, for instance, it may add to the growth of these unwanted plants. A healthy lawn typically needs 4lbs of Nitrogen in a season. Mulching can be up to 1lb of Nitrogen, reducing treatment.

Do Grass Clippings Add Nitrogen To Soil?

Grass clippings are an excellent addition to any compost heap. Adding clippings and mulch in the garden area can help retain essential nutrients, encourage growth, and regulate temperatures within your soil.

According to the University of Minnesota, some benefits of recycling your clippings into the lawn include, adding nutrients and organic matter, you’ll be able to use less nitrogen-based fertilizer, it may improve soil health if its sandy or heavy clay, will aid in helping manage the need to collect clippings after you’ve mowed. 

How To Dry Grass Clippings

Depending on what type of grass you have, drying will be a relatively pain-free process. Many people who own homes and have to maintain their lawns, will know that grass clippings can be very high in moisture and will need drying. If you are adding your clippings into existing mulch, for example, you can add wood chippings in with it as well, so that this removes excess moisture. If you are adding it into compost, you will need to dry it out. The way of using wood clippings is generally the easiest way and we recommend homeowners do this. 

Inorganic Mulches

People use this type of mulch to add variety to a landscape and to cover weed mats under certain areas of a garden. It is much more expensive than organic mulch and can cost anywhere between 1-5$ per square feet. It can be very expensive and permanent so you must make sure you take steps to minimize any unnecessary decisions or risks. Use with caution and make sure you take into consideration what you’re using it for. For example, adding too much stone to an area can suffocate a lawn / garden / plant and eventually lead to it dying out. We recommend using this type of mulch for softening the lines of driveways and edges.

Inorganic mulch can be used for stopping the growth of unwanted plants and weeds. For instance, covering a chemical solution over weeds is generally an inorganic process and can kill any weeds. Adding rocks or gravels to a certain area, can stop grown of any plants or grasses. Think of tarmac and gravel spread. Because this type of mulch doesn’t decompose, there are no added by-products for the soil. There are no extra nutrients added to the soil.

Grass Clippings in a Vegetable Garden

Because clippings contain nitrogen, an essential element for a plant, it should be added in thin layers in a vegetable garden that’s been kept clean and maintained. It should be added in with soft pruning’s, flower heads, vegetable matter, and even newspaper. You can sprinkle in a small amount of ash from a fire pit as this will add another essential element to the soil. This can aid the vegetable garden in being aerated and slow the rotting process down. Adding grass clippings can also reduce water loss and suppress weed growth. Once you have clipped your lawn, empty your catcher evenly over a vege garden, sprinkling it from the catcher as you go. You can continue to do this throughout seasons of growth

Making a balanced compost is a way to add nitrogen to your soil. A mixture of high carbon materials like dried leaves and crop waste and any small wood clippings. You can learn to make this into a very efficient compost. Compost can contain millions of beneficial fungi and bacteria that can constitute health soil. These organisms promote the breakdown of waste products. 

If you apply liquid fertilizer, for instance, you shouldn’t add any extra mulch wood chippings. Wood chips are fine over certain flower beds that don’t get much foot traffic, however, if you start putting the over soil, for instance, you will end up with a different problem entirely. Too much carbon in the soil and not enough nitrogen to compensate will cause issues. You can also do a PH test on your soil to see what your soil needs, in terms of nitrogen and carbon. 

How To Store Grass Clippings?

We like to use grass clippings as much, as you can see, around all our plants and any fruit trees we have. They usually break down very fast. In hot weather for instance you may not need to add any extra mulch to your garden, and are looking for ways to store it. 

If you have an excess of grass clippings, you can ask a professional to remove your extra waste, you can add it to your compost or you can wrap it up in haybale (depending on how much you have obviously). If you have a large garden, you can put all the clippings into large black rubbish bags, and let them dry out in the sun. They will get hot inside those bags and may even cook out any unwanted weeds.
