In Australia, our diverse climates mean that lawns can consist of either warm-season or cool-season grasses. Understanding the specific watering requirements of each is key for maintaining a healthy, vibrant lawn year-round. At StrathAyr Instant Lawn, we’re experts when it comes to keeping your lawn looking its best, and we know all the watering tips and tricks to help guide your way.

Warm-Season Grasses: Efficient and Drought-Tolerant

Warm-season grasses, such as Kikuyu, Couch and Buffalo, thrive in the warmer seasons. These grasses are known for their drought tolerance and efficient water usage.

Watering Guidelines:

1. Summer (active growth): During the warmer months, warm-season grasses require about 20-25ml of water per week (usually rainfall, but additional watering as needed). When watering, it’s best to do so deeply and infrequently, encouraging roots to grow deeper, enhancing drought resistance. Early morning watering is best as it reduces evaporation and fungal risks.
2. Winter (dormancy): In cooler months, these grasses enter a dormant phase, slowing growth and reducing water needs. Typically, natural rainfall suffices. However, if there’s an extended dry spell, a deep watering once a month may be beneficial.

Cool-Season Grasses: Consistency is Key

Cool-season grasses, including Fescue, Ryegrass and Kentucky Bluegrass, prefer cooler climates and are commonly found in Australia’s southern regions. They continue to grow and retain their colour throughout the cooler months and require more consistent moisture to maintain their lush appearance.

Watering Guidelines:

1. Spring and Autumn (peak growth): These seasons are optimal for cool-season grasses. Aim to provide 20-25ml of water per week, adjusting based on rainfall. Consistent moisture supports vigorous growth and resilience.
2. Summer (stress period): High temperatures can stress cool-season grasses. Increase watering frequency to 2-3 times per week (40-50ml), ensuring deep penetration to maintain root health.
3. Winter (reduced growth): Growth slows, but the grass remains active. Monitor soil moisture and water as needed, especially during drier periods.

General Watering Tips for All Lawns

1. Early Morning Watering: Watering between 6am and 10am minimises evaporation in warmer weather and also allows the lawn to dry before evening (particularly important in winter), reducing disease risk.
2. Deep and Infrequent Watering: Encourages deep root growth, making lawns more self-sufficient and drought-resistant.
3. Monitor Soil Moisture: Use a soil moisture meter or simply check soil dampness by hand to determine watering needs.
4. Adjust for Weather Conditions: Always consider recent rainfall and upcoming weather forecasts to avoid over or under-watering.

Smart Watering Starts Here

Understanding the distinct watering needs of warm and cool-season grasses is essential for maintaining a healthy lawn. By tailoring your watering practices to your specific grass type and local climate conditions, you can ensure your lawn remains lush and resilient throughout the year.

You don’t need to flood your lawn, just be sure to keep the turf and immediate underlying soil moist. You must be systemic, ensuring you water all areas. Keep in mind that during hot conditions, especially if it is windy, the lawn will dry out very quickly and additional watering may be required.

There are some out there who wouldn’t dream of fertilising their lawn very often or even at all, because it could lead to more mowing! But can you over fertilise your lawn?
For others there’s no such thing as too much of a good thing, right?
