Whether you already own a trampoline or your kids have been begging you to get one, the effect it has on your lawn may be a cause for some concern. A common question that many have is if their trampoline will kill the grass.
Like most things in life, there are pros and cons – which is definitely true when it comes to trampolines. The benefits of trampolines are that they offer a way to enjoy the outdoors as well as exercise for the whole family.
A drawback of owning a trampoline is it becomes an extended part of your yard. Thanks to its large size, a trampoline will affect the way you take care of and maintain your lawn. However, you have no need to worry as there are ways around these inconveniences.
Do Trampolines Kill Grass?
In most cases trampolines do not kill grass unless the trampoline causes the ground under it to get little to no moisture or sunlight. Many trampoline mats these days filter the sun’s rays and when placed over a sprinkler the grass under get enough light and moisture to thrive.
However, if you were to ask ten trampoline owners whether or not a trampoline is going to kill the grass then you will get both “yes” and “no” answers likely due to their own circumstances or maintenance practices.
There are too many variables at play for there to be a definite answer. It all depends on your geographic location, the type of grass you have, what kind of soil, how heavy your trampoline, what materials it’s made of, the angle the sun hits your yard, and so on.
Just because your neighbor complains about the grass dying in their yard thanks to their trampoline doesn’t mean it’s going to be the same result for you. In fact, there are many ways around this so you don’t end up getting an undesired outcome.
Why Does the Grass Die Under a Trampoline?
Understanding why a trampoline may cause the grass underneath it to die will be useful in determining how to prevent it. Because the trampoline is placed directly over the grass, it can’t help but have an effect on how it grows.
The more common result of this is the grass dies. This happens because the trampoline mat prevents sunlight and moisture from getting to the grass underneath. In turn, the grass becomes dry and lacks nutrients, causing it to die.
This effect is lessened for trampolines that are smaller in size and may affect your purchasing decisions.
In order to grow normally and maintain a lush, green appearance, grass needs regular access to sunlight. The sunlight makes grass able to produce well-needed chlorophyll, the important substance that keeps plants green & lively.
The weight of a trampoline itself can cause the grass to become damaged and die. This is especially true with large, heavy trampolines.
An extremely important thing to consider is if your yard has proper drainage. Without proper drainage, you may end up with a pool of water under your trampoline. This is bad because the legs of your trampoline will sink, resulting in an uneven jumping surface.
Can Grass Grow Faster Under a Trampoline?
In some cases, trampoline owners find that the grass underneath grows taller, faster, and lusher. This can be because the geographic location is hot and the trampoline is placed in direct sunlight.
While this might sound relieving if you happen to live in a hot climate, it’s important to consider that this area of your lawn will require more maintenance so the area doesn’t become overgrown.
Obviously mowing the lawn under a trampoline can be tricky so we have a guide to keeping it tidy here.
Can You Grow New Grass Under a Trampoline?
If you’ve already experienced grass dying underneath your trampoline, then you’ll be pleased that it is possible to bring the grass in this area back to life. It’s an easy process that can fix any type of damage your trampoline may have caused.
The fix is often as simple as re-planting grass seed. You can also lay down some sod or turf if there is a large area that has been affected.
Are There Trampolines that Don’t Kill Grass or Damage the Lawn?
Are you looking for the magical trampoline that doesn’t kill your grass or cause damage to your lawn? Unfortunately, there is no special made solution quite yet. Since every situation is different, it’s hard to determine what trampoline will keep your grass safe.
It is worth mentioning that trampoline mats made from polypropylene material rather than rubber allow more sunlight to pass through. Older trampolines typically use rubber mats, which are very good at keeping the sun and moisture from your grass.
Another feature that you might find desirable is a lightweight frame. Many find that lighter trampolines cause less damage to their grass. A lighter build also means you’ll be able to move your trampoline around your yard much easier. Why would you want to do that? We’ll go over that shortly.
Consider a Sunken Trampoline
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.
How to Stop a Trampoline From Killing Grass
Unwanted dead grass patches where your trampoline sits don’t have to be a guarantee. There are a few simple things you can implement into your lawn maintenance routine to help prevent the grass from dying.
Move the Trampoline Regularly
One of the best ways to keep your grass healthy is by moving your trampoline around your yard on a regular basis. By doing this you allow the grass to have some breathing room.
Because your trampoline won’t be covering one specific spot of grass until it eventually dies, your yard will stay green & beautiful. Even if the grass suffers from some dryness and being nutrient deficient, when you move your trampoline it will get a chance to make a full recovery.
Take note that this is a great option if you have multiple locations in your yard that are level. Trampolines must be placed on a level surface to ensure a safe jumping experience. If this is not the case for you, you can hire landscapers to level out your yard.
Moving a trampoline might not be ideal depending on its weight and size. Some trampolines are lightweight enough for one person to move on their own. Many trampolines, however, are quite large and may require some helping hands if you have some.
Place a Sprinkler Underneath Your Trampoline
If moving your trampoline regularly isn’t going to cut it, then you can choose to place a sprinkler underneath it every once in a while. This is particularly useful if one of the main problems you are experiencing is dryness.
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.
What Other Options Do I Have?
Sometimes trying to deal with the maintenance and upkeep yourself isn’t going to cut it. Whether you’re simply too busy or you feel that it’s a waste of time, there are other ways to deal with dying grass and preventing it from happening again in the future.
If you’ve been dealing with trying to fix the dead grass in your backyard and have finally had enough, then the following alternative options may be just what you’re looking for.
Place a Grass Mat Underneath
In some cases faking it doesn’t cut it. But when it comes to your trampoline, a synthetic grass mat can be a total lifesaver. It’s only a one-time investment into never needing to worry about the grass underneath your trampoline ever again.
Aside from removing maintenance, you also remove the need to move your trampoline around your yard. The benefit of keeping your trampoline in one place is that you don’t have to worry about shifting things out of place when you move it.
Install Organic Material Under Your Trampoline
Another alternative you can consider is installing a large base of organic material, such as mulch, sand, or bark, underneath your trampoline. This provides a soft, stable surface that will not only absorb impact but also remove the need to micromanage the grass underneath.
Creating an organic base for your trampoline is a one time process that you may find worth it. First, you need to dig up a 10-12 foot deep trench with a diameter allowing as much as 4-6 feet of space around your entire trampoline. Next, this trench is filled with your desired organic material. Simply install trimming around the edge to keep the material inside the area.
Place It Over Gravel
Placing your trampoline over gravel is another option that is overlooked. If you don’t have gravel in your yard, you can create a gravel patch large enough to place your trampoline on. Gravel is very low maintenance and removes the need to worry about the landscaping underneath your trampoline.
