Syringing is a very light application of water to wet the leaves of the turfgrass but not necessarily to get water down into the soil. Usually syringing is done during the hot part of the day to reduce heat stress by cooling down lawn and soil surfaces as well as the immediate air surrounding the grass plants.
Here are three situations in which syringing might be considered on lawns:
- Lawn is infested with one of the patch diseases. Daily syringing during high temperatures can reduce the severity of damage and encourage recovery.
- Lawn is newly seeded. Germinating seedlings have minimal root systems and can easily die from water stress. Light, frequent watering is necessary until the plants are established and have developed adequate root systems. Syringing during high daytime temperatures will help keep the seedlings cool and moist.
- When an established lawn is showing stress on a hot day but cannot be watered adequately until later.
