Compacted soil makes it difficult for plants such as grass to develop. Compaction limits the movement of water through the soil and the ability of the roots to grow. The water surplus that develops creates a lack of oxygen in the ground, which is also not good for the plants.
Compaction damage can affect new or existing lawns. Some causes are: constant vibrations from traffic in urban environments, the use of heavy vehicles when laying the lawn or heavy foot traffic on the lawn.
How Can The Ground Be Loosened Up?
Loosening up established vegetation areas such as grass areas is done by aeration. This is done with special spike or hollow tine aerators. A spike aerator simply punches a hole in the ground. A hollow tine aerator stamps out cylindrical holes in the earth, approximately 3 inches deep and brings the plug to the surface of the earth.
What Are The Advantages Of Aerating?
- Stronger root growth
- Increased water permeability
- The grass can better withstand dry weather conditions
- Better root hydration
- The need for weed killer is reduced
When Should You Aerate?
The grass should always be growing well before you start deep aeration. You should never aerate when the grass is not growing well or when it is stressed, such as during a dry period.
