Aerating a lawn will split the roots of the grass, this encourages offshoots to grow and in turn, will thicken your lawn.
Lawn Spiking and Aerating allows the free movement of nutrients, water and air around the roots and helps prevent the growth of moss. Most lawns need to be relieved of compaction of the soil and it is the process of aeration which allows this. Heavy soils need to be aerated as they will easily become compacted, which leads to poor root development and poor drought and disease tolerance.
Machinery is very expensive to hire and also heavy to manoeuvre, Cornwall Lawncare can provide this service and do a difficult job properly.
