Lawn Aeration

Lawn aeration is desired to relieve compaction. The standard techniques employed as hollow tining and solid tining. This is a good practice for home lawns and sports pitches which get compacted over time. Compaction affects the grass negatively. When grass is compacted, roots do not grow well. Air and water, vital ingredients for a healthy lawn are significantly reduced. The result is that the grass degrades. Unhealthy grass has less visual appeal. It is also more susceptible to wear.

Lawn aeration is accomplished by hollow or solid tining. Hollow tining involves the driving of hollow tines into the ground to make holes. This allows air and water into the root zone. When hollow tining is done, cores of grass are ejected. This can be collected for composting or allowed to compost on the grass surface. In golf courses or other recreational area, collection of cores is standard practice. For home lawns, the cores can be left to decompose. When hollow tining is done it is often recommended to top dress the grass with sand. This covers the holes and allows for the penetration of water and air.

Solid tining is also known as pencil tining. This is a form of lawn aeration that is similar to hollow tining. The only difference between solid tining and hollow tining is that the tines used are solid and no cores are ejected from the ground. Similarly, after a hollow tining job, top dressing and other standard lawn care management practices can be done.

Lawn aeration should be accompanied by the application of fertilizers and other soil improvers. This is to take advantage of the increased air spaces on the grass before compaction re-occurs again.

In lawn aeration, coring machines are used. These can be walk behing or tractor drawn. If hollow tining is desired, hollow core tines are used. If solid tining or pencil tining is desired, solid tines are used.
