What turf management practice can improve drought resistance?

Deep rooting through proper irrigation is a highly effective turf management practice for improving drought resistance. When turfgrass has a robust and deep root system, it can access moisture that is further down in the soil profile. This ability allows the grass to withstand dry spells and drought conditions better than grass with shallow roots.

Proper irrigation promotes healthy root development by encouraging the roots to grow deeper into the soil in search of water. When grass is watered deeply but infrequently, it fosters a deeper root system, which in turn enhances the plant's ability to survive during periods of limited water availability.

In contrast, shallow watering can lead to a weak root system, which makes the turf more susceptible to drought stress. Frequent mowing does not directly relate to drought resistance; instead, it can stress the grass if not done properly and may not impact root depth significantly. Applying a thick layer of mulch is more commonly associated with landscape beds or garden areas rather than turf areas, as mulch can smother grass if used inappropriately.
