Are Grass Clippings Good For Vegetable Gardens? – The Facts, Guides, And More You Need To Know

What are the grass clippings?

The grass clippings are grasses that people have cut with various planting equipment, yet, they are left behind for some reasons.

Sometimes, a grass catcher or a mower can capture the grass clippings when people cut or mow their lawns.

The lower the mower’s quality, the more likely many grass clippings are around the lawns. However, there are also times when people couple a mower with plastic bags. At such times, the mowers can catch more grass clippings, too.

The grass clippings tend to be either short or extremely short in their lengths. Such things apply particularly when people follow the “one-third rule” in mowing their lawns.

What are the all-about of vegetable gardens?

Today, people often create vegetable gardens inside their houses. Even though green vegetables still dominate vegetable gardens, people are starting to consider vegetables with different colors (red or purple) to grow due to their economically-priced seeds.

On the other hand, people categorize some grasses as vegetables. Some other people are intentionally burying grass clippings to make their vegetable gardens appear more aesthetic, particularly those with outdoor vegetable gardens.

At the same time, aesthetical pleasure alone is not enough for some people. After all, vegetable gardens exist so we can eat vegetables that we plant without going to supermarkets all the time. So, “are grass clippings good for vegetable gardens?” We will see the reviews in this article.

Are grass clippings good for vegetable gardens?

After knowing the grass clippings’ relations to the vegetable gardens, you may wonder, “Are grass clippings good for vegetable gardens?”

The good news is that sure, it does.

It doesn’t matter if some people think grass clippings are only useful for aesthetic purposes. Many grass clippings mulch vegetables well, especially tomatoes. Such things make grass clippings useful for making the harvested vegetables taste more delicious and healthy.

There are many ways to use grass clippings in the garden. They add nutrients to the soil, stop weeds from growing, and keep water in the soil. In addition to trace levels of other plant nutrients, they include 4% nitrogen, 2% potassium, and 1% phosphorus.

Many people pair grass clippings with organic fertilizers when giving nutrition to their vegetables. The more the grass clippings and the fertilizers work in synergy to hold moisture, the more fertile the vegetables will be.

How to make organic mulch from grass clippings?

The ability to hold the moisture well and the compatibility with lots of organic fertilizers are two traits that grass clippings possess that make it possible to be organic vegetable mulch. Here are the ways we can do to make an organic mulch from grass clippings:

1. Grow your lawn for around 1-2 inches longer than their average lengths before you mow them. Then, wait until the grasses are dry enough.

2. Spread the grass piles inside the catch bag anywhere near your garden. Let them sit overnight. Repeat until both sides turn golden in the sun.

3. Store the grass clippings inside a garbage bag, a pitchfork, or anywhere dry.

4. Then, as a final step, you should ensure that the mulch is no deeper than one inch when you apply it to your vegetable gardens. 

The most important rule for using grass clippings as mulch is to arrange them thinly.

This happens naturally when mulch is put as the last stage after weeding. Use enough clippings to cover the surface, either freshly cut or those let to dry in the sun.

What dangers do grass clippings pose to vegetable gardens?

Now that we’ve got the answer to whether grass clippings are good for vegetable gardens or not? It’s time for us to elaborate on the opposite sides.

Mulch from grass clippings requires different treatments than mulch from other sources. The special treatments often mean balancing the thickness and the wetness of the grass mulch. Else, the grass clippings can form into slimy mats.

Grass clippings are also vulnerable to burning issues due to their extremely high nitrogen contents. The more they decompose (and the more we abandon the decomposition), the more heat they will produce. As a result, they may burn the vegetables or the whole garden.

The easy-to-burn nature of grass clippings becomes even more dangerous with their easy-to-blow characteristics. Many authorities also warn of the dangers of grass clippings and compare them to gravels, sands, etc.

What are the all-about of grass clippings’ decompositions?

Grass clippings will typically decompose after 3-4 weeks of mowing the lawn. The more people properly mow the lawn, the more speedy the decomposition processes. It is because grass clippings can filter down to the soil.

The grass clippings will start getting invisible in the first two weeks of the decomposition process. The grass clippings inside the soil will feed soil organisms and recycle plant nutrients in such conditions.

The grass clippings will completely break down 1-3 months after the decomposition process. Even though breaking down means faster recovery for the vegetables, more special treatments are needed to ensure the grass clippings won’t burn.

Even so, it’s rare to see grass clippings that can completely break down. At some points, people leave the grass clippings as they are. As a result, the roads become more dangerous to overcome.
