Now is the time to top dress a lawn. Top dressing, or adding a layer of top soil (usually a combination of sand, silt and clay), is usually done when your lawn is in active growth – once your regular, weekly mowing routine has kicked off – to strengthen the health of the grass and to achieve a neat, flat finish.
Ensure you top dress the lawn on a day that's warm but not hot, and repeat the process again in fall.
