Irrigating newly planted lawns—whether natural rolled sod or seeded—is very important. If watering isn’t done properly, it can cause soil erosion, seed displacement, and patchy growth. At Frogs Group, we emphasize that proper watering immediately after sod placement helps your lawn develop strong roots and stay healthy for years. Always use a sprinkler or hose nozzle when watering, and keep the water pressure low to prevent damaging the sod.

The best time to water is early in the morning or at night. Ideally, water before 10 AM so the moisture can soak into the roots effectively. Avoid watering during the hottest hours of the day to prevent water loss through evaporation.
One simple way to determine irrigation needs is by using peat moss. Besides retaining soil moisture, peat moss indicates when watering is needed—when its color shifts from dark to light brown, it signals dryness.
This makes it easy to monitor soil moisture without touching the soil. For this reason, adding peat moss after installation is highly recommended to help preserve your lawn’s growth and vitality.
Types of Lawns
Seasonal Lawns:
These grasses typically grow in regions with hot summers or cold winters. Their growth depends on the season and they require proper feeding and watering to stay healthy. The amount and timing of irrigation should be adjusted based on the plant’s needs and the local climate to prevent root drying or rotting.
Perennial Lawns:
Perennial grasses mostly grow in temperate climates and remain green throughout the year. They need regular but balanced watering. For better maintenance, a specific irrigation schedule with precise timing and appropriate water amount should be established so the roots remain moist but not waterlogged.
Important Lawn Irrigation Tips Include:
Water Amount: Avoid overwatering. Irrigation should be done properly with the right amount of water for the lawn. You can use an irrigation gauge to help with this.
Irrigation Timing: Never water during the hottest hours of the day. The best times for proper lawn irrigation are early morning or evening.
Intervals Between Watering: The time between watering sessions should be adjusted according to the grass type, local climate, and soil moisture level. In warmer seasons, due to increased evaporation and soil drying, more frequent watering may be necessary. In cooler or humid weather, watering intervals can be extended to prevent water waste and root rot.
Irrigation System Maintenance: For proper irrigation system performance, regular inspections and maintenance are necessary. Checking nozzles, pipes, and water pressure prevents failures and ensures uniform and effective watering.
Warm-Season Lawns
Tropical grasses like Bermuda grass, Zoysia grass, Bahia grass, Buffalo grass, St. Augustine grass, and Centipede grass are suitable for areas with abundant sunlight and warm to hot climates. These grasses grow vigorously during the hot summer season but go dormant and grow less during cold seasons.
Cool-Season Lawns
Cool-season grasses such as Ryegrass, Festuca, Bentgrass, Bluegrass, and Kentucky Bluegrass perform excellently in temperate and cold climates. Unlike warm-season grasses, cool-season grasses go dormant in summer and stop growing but grow lushly in spring and fall. With the arrival of winter and wind, they revive and continue growth.
When watering, if there is no rainfall, these grasses require watering once every three weeks. Overwatering can lead to weed growth and thatch buildup.
Natural Lawn Watering Amount
One key point in natural lawn care is irrigation. The watering amount should be appropriate. Generally, lawns require about 2.5 cm of water per week. However, this amount varies depending on factors like climate, wind intensity, evaporation rate, and grass growth speed. For example, lawns in hot and dry areas or windy days need more water, while cooler or humid areas require less to prevent moisture buildup and root damage.
Automatic Irrigation System
One of the best ways to manage lawn irrigation properly is using an automatic irrigation system. These systems save time and water but must be set up correctly. Instead of frequent shallow watering, it’s better to set a regular schedule for deep watering with appropriate intervals. Typically, watering twice a week for 12 to 30 minutes per session is sufficient for most lawn types.
When setting the system timer, consider soil type, wind intensity, and evaporation rates. It is also recommended to check soil moisture every 15 minutes to ensure water penetrates deep into the roots.
Choosing the Right Sprinkler for Lawn Irrigation
Choose the sprinkler type based on the size and use of the area:
- Small Areas (e.g., gardens and villa yards):
- Hunter PS spray sprinklers are recommended.
- For more water efficiency and advanced technology, MP models are good choices.
- These sprinklers are designed for areas up to 5 meters and provide uniform rainfall irrigation.
- Medium to Large Areas (parks and urban spaces):
- Hunter rotary sprinklers like PGJ and PGP are very efficient.
- By adjusting different nozzles, the spray radius can extend up to 15 meters.
- Very Large or Sports Areas (e.g., stadiums):
- Powerful Hunter models like I40, I60, and I90 are ideal.
- These sprinklers can spray water up to 30 meters and are designed for wide open spaces.
Careful installation, adjusting spray angles, and periodic system checks increase lawn longevity and save significant water.
Causes of Lawn Browning
During hot summer days, lawn color may change from fresh green to brownish-green, appearing dry or dead at first glance. However, many cool-season grass species enter a dormant or resting period not only in winter but also in summer. During dormancy, grass stops growing to prepare for the next growing season. When temperatures drop and rainfall returns, the grass revives and regains its green color.
Some species exit summer dormancy faster. However, if brown lawn patches show footprints after walking, it likely means your lawn is dehydrated. In this case, increase watering so water penetrates at least 2.5 cm into the soil.
On the other hand, overwatering can also harm the lawn. Signs of excess irrigation include:
- Formation of a compact, muddy soil layer
- Growth of fungi and increased weeds
- Standing water on the ground
- Bare patches in the lawn
- Soil feeling soft and slippery when walking on it
