What Causes Grass Bubbles – How are They Formed?

If you’ve never seen a bubble of grass in your backyard – or even seen one at someone else’s then you’ll realize they’re amazing, just as blisters on the grass. If you’ve never encountered one, you can watch a video to watch. What is the process by which they are formed?

Lawn bubbles result from water being trapped under the grass, and is in a position to not drain away or absorb naturally. If water gets trapped beneath the roots of the grass, it floats on top of the bubble, creating an area of raised, blistered appearance in the grass.

Let’s take a look at lawn bubbles more in depth and discover the nature of them, how they develop, and the best way to eliminate them before they could kill your lawn…

What is a Grass Bubble? (Also Called Lawn Blisters)

These are also known as grass bubbles, also known as lawn blisters are patches of grass that are caused by water that has been trapped under the surface. Similar to a blister that you get on the foot (and I’m sorry to make a somewhat painful comparison) They are soft and squishy because they’re full of liquid.

They can be quite massive (we’re not talking about adorable tiny blowing bubbles here) If you are sitting on one, it’s like sitting on an actual bed of water. It’s like a blister on your skin (apologies for the pun) It’s not damaged, but it is it’s swollen and raised.

Lawn bubbles aren’t often seen on lawns of our homes Most of us don’t see them, much less see one appear on our lawns. Anyone who has suffered from lawn blisters may initially be concerned when areas of their yard begin to rise, but lawn bubbles don’t pose a risk for people. In fact, kids are likely to use them as unintentional trampolines.

However, you must to eliminate these as they could harm your lawn. Additionally, you must find out what’s behind the bubble of grass.

What Causes Grass Bubbles – How are They Formed?

Lawn bubbles occur due to water being trapped beneath the grass, and is not able to drain or absorb naturally. When the water gets accumulated under the surface of grass’s roots The grass eventually ends up floating above this water-filled pocket. This creates a bump-like area that rises up that is visible on lawns.

There are two reasons for thisissue: heavy rainfall or the burst of a water pipe.Heavy rain will be the main reason for lawn bubbles. Sometimes, we encounter storms that come fast and intense that our lawns aren’t able to take the water away. The rain can get trapped in your lawn.

It is likely to happen if there is an area of plastic underneath your top soil. If you did not lay your own plastic, you could not even realize that there is plastic beneath your lawn. In areas where the soil quality is poor, landscapers may put a plastic sheet over the top of their lawns, then over it with higher-quality, imported topsoil. The turf is then mowed or seeded to make an attractive lawn.

However, bubbles in lawns can occur even without the plastic. They’re more likely in areas with an extremely dense and tightly growing lawn. It’s a awful reward for having a dense and lush lawn.

We now are aware that rain is the primary reason. However, what happens if it’s been raining heavily , and you see the appearance of a lawn bubble? It could be a sign that there’s a damaged water pipe underneath the surface. In this situation the lawn bubble can be an excellent lifesaver as it will draw focus to the issue.

Rarely the appearance of a lawn bubble can be caused by the accumulation of methane. This is not a serious issue and it’s due to the natural process of rotting the vegetation. There’s also a belief of a grass blister that could mean sinkholes, but this is not the situation (although it is advisable to seek professional guidance if you have a good evidence that there is a sinkhole in your lawn).

Are Lawn Blisters Harmful to Your Grass?

Yes, bubbles from lawns can cause the death of your lawn. This is because the water layer that lies beneath the surface strips the grass of the nutrients they require.

But isn’t it likely that grass bounces back from a period of wetness of weather? It usually will, provided that the soil isn’t damaged. To better understand the ways that a lawn blister could cause grass to die, imagine what’s happening underneath the bubbled surface.

The water has pushed an overgrowth of grass and on top of the soil. The grass’s roots are cut off from the soil and are left trampled by in water. If the water in this area isn’t cleared and the grass isn’t capable of reaching its roots to the soil in order to pull the nutrients it requires to grow.

Is water under grass dangerous?

A typical, water-filled , lawn bubble won’t cause any harm to anything other than your lawn. They don’t indicate that there’s a hole in your lawn, but should you suspect that the bubble could be the result of an exploding pipe or leak then you’ll have to take action swiftly.

There’s a unusual (but highly well-reported) occasion where grass bubbles could be hazardous as they were in Siberia in the year 2016. Massive methane-filled bubbles erupted in alarming quantities, believed to be the result of the rising temperature on the planet, which caused melting of the permafrost.

Mesopotamia-filled pockets resulting from melting permafrost are unlikely to be the cause of any type of blister that you see on your grass. But, if the need arise to Google “are lawn bubbles dangerous” the following story will appear in the results. We thought it would be better to place it in a wider context!

How can I get rid of the lawn bubbles that are forming?

Before draining the grass, you’ll have to identify the source. If the issue is a damaged water pipe, fixing it will be more important than saving your lawn. To be honest it’s not worth doing a clean lawn repair in an area that’s likely to require additional work. In these guidelines we’re assuming you’ve inspected the area with bubbles and determined that it’s been caused by excessive rain.

It’s time to flush the flake… You’ll need to puncture it with a sharp garden tool, then let the water out. Keep in mind that the less holes you create more damage is less likely on your grass.

If it’s a big blister that you do not want to see your lawn to be flooded it is possible to dig an opening towards a drain to encourage the water to flow away quickly after the bubble has popped. But, now you’re stuck with a trench in your backyard…

You’ve cracked the bubble and then the water is gone and your lawn has dried up again. What can you do to treat the marks of puncture (or drainage trenches) which are left by the slashing of the blister? Filling the holes with grass seed mix ready-mixed with fine sand is the most effective method.
