Top 5 Tips From Keeping the Grass Under Your Trampoline From Dying


Most people you ask about whether their trampoline kills the grass underneath it will tell you it certainly does.

And most of those people will be right.

So what can be done to keep your grass from dying? Move your trampoline regularly, put the trampoline directly over a sprinkler, use lawn decorations to reflect the sun onto the grass, regularly plant lawn seed and grass feed, or put your trampoline in the ground.

In this article, we will cove the above and much more.

Why does my trampoline kill my grass?

There are two main reasons your trampoline kills the your grass.

Sunlight

Your trampoline will come with a nice thick, dark mat.

The trampoline mats are made thick so that it does not break easily and people will not fall through it.

This is great because it keeps the people jumping nice and safe.

But the thickness and dark color of it keeps any sunlight from getting through to the grass below.

So your grass is not getting the sun it needs to grow appropriately.

Moisture

Grass needs some kind of moisture to survive.

And the grass is typically dependent on either the rain coming down on it or a sprinkler giving it sufficient water.

The trampoline mat keeps it from getting either.

Again, because of the thickness of the mat, when the rain comes down or the sprinkler goes off, the mat is going to catch most of that moisture and keep it all.

So your grass does not get the moisture it needs to survive.

Weight

The heaviness of the trampoline and the constant bouncing can also cause some problems for your grass.

Every time you jump on the trampoline, the trampoline will sink a little bit lower into the ground and cause a bit more pressure.

This pressure can often overwhelm the grass and cause it to die out.

Solutions

There are a few solutions you can implement to avoid most of the above concerns.

Move your trampoline regularly

Grass can usually last some time (around a week) without getting direct sunlight and water.

So if you keep your trampoline in one place for that amount of time, the grass might survive without dying.

But after that point, you run the risk of your grass dying.

So a good rule of thumb is to move your grass regularly and do it during a time when you will remember.

Habits can be one of the most important things you establish in your life.

Starting a habit when you move your trampoline can be very important.

If you mow your lawn once a week, you are going to have to move your trampoline, most likely, to mow underneath it.

That might be a good time to move the trampoline to a new spot since you have to move it anyway.

Even if you are not mowing your lawn that regularly, make it a habit to move your trampoline once a week.

Put your trampoline directly over a sprinkler

As discussed previously in this article, your trampoline mat is going to catch any moisture that comes down on it, not letting any through to the ground.

The grass underneath your trampoline has very little chance of getting water from above.

So your next best option is to place the trampoline right over a sprinkler, whether that is an inground sprinkler or one above ground that you can move around as well.

This way, the trampoline mat cannot keep the grass underneath from getting the water it needs.

From TurfMechanic.com:

For those concerned about the integrity of their trampoline frame when exposed to water, there is nothing to worry about as long as the mat and frame covers are in place. Placing a sprinkler under your trampoline is completely safe and will not damage it in any way when the proper precautions are taken.

Keep in mind that a wet trampoline can also be a danger, so if you are going to have a sprinkler directly underneath the trampoline, make sure no one is jumping on it either wet or when the sprinkler is going off.

Reflect the sun onto the grass

Our kids like to annoy each other every once in awhile by reflecting the sun off an object, like a watch face or a mirror, into the eyes of one of their brothers.

And no one likes to have the sun reflected into their eyes.

But this same basic concept can be applied to getting sun onto the grass underneath the trampoline.

Depending on the time of day, you can reflect the sun off of some lawn decorations back onto the grass underneath the trampoline.

This certainly will be a difficult and time-consuming task, seeing that you would have to get the angle right off the lawn decorations.

But it could be worth it to get your grass some sun and keep them from dying.

Plant lawn feed and grass seed on the grass under your trampoline

According to GetTrampoline.com:

If you plan to set up a trampoline over grass in a fixed spot, you need to prepare the grass in order to keep it alive. If you live in a very warm region, it is possible that no additional preparation will be necessary. In all other cases, however, a great way to keep the grass alive is to prepare some lawn seeds and grass feed. By planting new seeds regularly, you can make sure the grass patch remains healthy and verdant.

Grass needs the sun to help it grow.

You can help the lack of having very much sun by planting grass feed.

The grass feed gives the lawn some of the nutrients it needs to continue to grow.

Planting lawn seeds helps to fill in the gaps in the places where grass is in the process of or already dying off.

Check on the grass regularly and fill in with grass seed where grass is dead and lawn feed where the grass is beginning to die.

So taking a few extra steps ahead of time might help you save the grass.

Put the trampoline in the ground

A way to not have to worry about the grass underneath the trampoline is to just get rid of the grass (and ground) underneath the trampoline.

Burying your trampoline in the ground “gets rid of the middle man” and you no longer have to worry about the grass.

If you can spare it, dig yourself or hire someone to dig a hole in the ground for your trampoline.

After the hole is dug, put a foundation around the hole to keep it from caving in, then place your trampoline in the ground.

Having an inground trampoline has a lot of advantages, besides you not having to worry about the grass, including decreasing the likelihood of someone getting hurt while falling off the trampoline.

According to TurfMechanic.com:

If you really want a trampoline that doesn’t kill the grass, then you should consider paying to have your trampoline sunken. A sunken trampoline is mounted underneath the ground so that its jumping surface is level with the grass.

Sunken trampolines remove the need to worry about maintaining the landscape underneath as well as the risk of someone falling off. If you choose to go this route, then you’ll need to choose your spot wisely since the trampoline will be in the same spot until someone digs it out.

It might not be the best, and least expensive option to put your trampoline in the ground, but putting the trampoline in the ground does in fact take away the worry about the grass dying underneath it.

Summary

A wonderful-looking lawn is one of the most satisfying things as a homeowner.

So when we purchase a trampoline, we begin to worry about how our lawn is going to look, and rightfully so.

To avoid the trampoline ruining the grass: move the trampoline regularly, put the trampoline over a sprinkler, reflect the sun to the grass underneath the trampoline, plant lawn seed and grass feed, and consider putting your trampoline inground.
