You can top dress at any time during the year. Usually, top dressing is recommended during the growing season, but not during extreme heat waves. As a general rule, we recommend top dressing with compost at least once a year.
However, there are two factors that determine the frequency of top dressing:
- The amount of usage that a lawn gets;
- The health of the soil in which it is growing.
Heavily used lawns and unhealthy soils may benefit from more frequent applications.
