Bryan from Billings, Mt writes
You normally apply a fungicide like Headway before signs of the disease common to occur in your lawns starts to be present. If you typically get a disease in the lawn every may, for example, then you would want to put down the headway a few weeks before the time it normally presents itself in your lawn, and continue reapplying at the appropriate intervals per the product label for that disease to keep it at bay.
