Grass Under a Trampoline: Will It Die?

Yep. Sorry, grass lovers.

But hold up — it’s not all doom and gloom for your backyard.

A trampoline can kill the grass under its metal legs and frame. All that weight sitting in one spot can squash the grass, while the frame blocks sunlight and airflow. Leave it there long enough and those patches can turn yellow, thin out, or disappear.

Why Does a Trampoline Kill Grass?

The main trouble comes from the metal legs and frame sitting in the same spot for ages. They can squash the grass underneath while blocking the sunlight and airflow it needs to stay healthy.

But here’s the cool bit: the grass under the trampoline mat can actually grow pretty well.

Why?

The trampoline gives it some shade. And in a sunny Kiwi backyard, a bit of shade can be pretty sweet.

It helps the ground stay cooler and can slow down moisture loss. Rain can still get through the mat, so the grass underneath isn’t completely cut off from a drink.

Can Grass Grow Under a Trampoline Mat?

Yep — sweet as!

The mat still lets some rain through, while the shade can help protect the grass from getting hammered by the sun.

So you might end up with:-

Under the metal legs: Grass = not having a good day. Under the trampoline mat: Grass = sweet as.

Of course, it depends on your type of grass, how much sun your backyard gets and how long the trampoline stays in one spot.

Want to keep the lawn looking mint?

Shift the trampoline every now and then and give those patches some sun, water and time to bounce back.

So yeah, the trampoline might annoy your lawn.
