Generally, a lawn bubble is caused by water that can’t drain away because it has become trapped beneath the grass. This can happen during heavy rains or after a water pipe has burst underneath the ground.
When a bubble occurs, the water that has collected under the lawn becomes more concentrated and pushes the grass up. This can make it difficult for the grass to reach the soil and absorb nutrients.
Lawn bubbles can also be a result of soil compaction and prolonged droughts. Soil compaction can cause the roots of the grass to grow dense and compact, making it hard for water to seep through the ground.
In some cases, lawn bubbles can be caused by a plastic layer under the grass that was laid before it was planted. This type of plastic can be a part of a soil improvement system, or it may have been spread over the lawn area to cover poor soil before new topsoil and grass was added.
If you have a grass bubble on your lawn, the best thing you can do is to try to remove it. To do this, you will need a sharp-pointed tool to puncture the bubble and create some drainage areas.
Once you have the necessary trenches, you can start tearing up the grass bubble while doing as little damage as possible. If the bubble is too large to tear up, you will have to plan a way to drain it while doing as little damage as possible to the lawn.
