Moss On Older Lawns.

Question
How to treat persistent moss in the older lawns?.
Answer
Moss is often a problem on older lawns, especially lawns that have, in the past, had a good deal of attention and care. This is because lawns are suited to slightly acid soil conditions. These conditions are normally created by the use of artificial fertilizers containing ammonium compounds. However, after a number of year’s treatments, a very acid soil is created, which makes it hard for the grass to access the nutrients from the soil, reducing the grass’s growth and allowing other plants to invade the lawn. In common with most grasses most weeds also do not take to very acid soil conditions, but one plant ideally adapted to these conditions is moss and will take over such lawns.
The solution is to carry out a soil test to check the soil Ph, anything below Ph 6 will require the application of lime and then scarifying to remove the moss. As the Ph rises after the application of the lime the nutrients in the soil will become more available to the grasses in the lawn and you should start to see a recovery.
If the Ph level is 6 or above(this is often indicated by the growth of daisies in the lawn)then it is almost certainly the lawn’s drainage that needs to be looked at.
