Topdressing soil texture for lawns should be slightly coarser than the surface soil.

• A. True
• B. False
• C. Slightly finer
• D. The same texture

Answer: (A)

Topdressing works best when it creates a surface that breathes and drains well. Using a material that is slightly coarser than the surface soil gives enough pore space for water to infiltrate and for roots to access air, while still smoothing the turf and filling low spots. If the topdressing is too fine, it can seal the surface, leading to crusting, poor drainage, and restricted root growth. If it’s too coarse, it won’t fill and level the surface effectively. So aiming for a texture just a bit coarser than the existing surface allows the layer to blend in gradually while improving overall soil condition.
