Does your lawn have a compaction problem?
If your lawn has thin areas of grass, if it goes very brown throughout the hot months of summer, drains poorly, or even if it just struggles to grow throughout the year, then there is a good chance that it is suffering from a soil compaction problem.
This is two soil cores taken from a lawn on the same day. The left one looks normal and contains plenty of moisture, the right one is compacted and totally dry. An area of your lawn with no moisture or oxygen will mean that the lawn will suffer.
What is the cause of this compaction?
Foot traffic, lawn mowing and even gravity and rain causes compaction on your lawn. This squeezing together of the upper surface of soil reduces the ability of air, water and nutrients to penetrate through into the root zone. This has an adverse effect on the quality and visual appearance of your lawn.
There is a solution... aeration!
Of the two possible types of aeration, Hollow tine aeration is the more effective treatment for severe compaction problems. This is different to solid-tine aeration because it physically removes a 'core' of soil, allowing it to relax and breathe, creating tiny cracks in the ground below through which air, water and nutrients travel, helping to strengthen the grass root system. Aeration can be achieved using solid or hollow tines and I will be happy to advise you as to which option would be most suitable for your lawn. As hollow-tine aeration removes a core of soil from your lawn, it is very important that these cores are removed, as, not only are they unsightly and cause a mess on your paths, but they also harbor weed, seeds and moss spores, add to your thatch problem and when stepped on create little patties of soil which will be perfect seed beds for weeds. South Hants Lawns always remove hollow-tine cores. They are certainly NOT a "top dressing"!
