Should You Water Lawn After Mowing?

Maintaining a lush, green lawn requires a combination of proper watering and regular mowing. Both practices play crucial roles in keeping your lawn healthy and vibrant. However, many homeowners wonder when is the right time to water their lawns. 

Watering ensures that your grass receives the necessary hydration, helping it withstand drought conditions and promote healthy growth. On the other hand, mowing helps maintain an optimal height for your grass, prevents weed growth, and encourages lateral spread, leading to a denser lawn. 

Both practices work in tandem to create an environment where your lawn can thrive. Keep reading to learn more about watering and mowing your lawn and proper lawn care in general.

The Ideal Lawn Care Routine

To establish an ideal lawn care routine, it's essential to understand the order of watering and mowing. In general, it is recommended to mow your lawn before watering. This approach allows the freshly cut grass to dry out slightly, reducing the risk of fungal diseases caused by excessive moisture. However, there are exceptions, and it's crucial to consider certain factors before deciding whether to water the grass after mowing.

The Effects of Mowing on Your Lawn

Mowing helps control the height of your grass and affects its water requirements. When you mow your lawn, you remove a portion of the leaf blades, which reduces the overall surface area available for transpiration. 

As a result, the grass loses less water through evaporation, meaning it may require less watering. This is particularly true if you mow your lawn to the recommended height for your grass species.

Benefits of Watering After Mowing

While mowing can reduce water requirements, there are situations where watering after mowing can be beneficial. Let's explore some of the advantages.


Mowing can be stressful for grass, especially during hot and dry periods. Watering after mowing provides immediate rehydration, helping your lawn recover from the stress and promoting faster regrowth.

Cooling effect

Watering your lawn after mowing can have a cooling effect on the grass blades. This is particularly helpful during scorching summer days when the heat can cause the grass to wilt or turn brown. Watering can revive the grass, maintaining its vibrant green colour.

Soil moisture enhancement

Watering after mowing can help replenish the moisture content in the soil, especially if you live in a place with sandy or fast-draining soil. This additional moisture can improve the overall health and vitality of your lawn.

Nutrient absorption

Watering after mowing allows the water to penetrate the soil and carry essential nutrients deeper into the root zone. This promotes better nutrient absorption by the grass, leading to healthier growth and improved lawn quality.

Weed control

Watering after mowing can disrupt the growth cycle of certain weed species. Watering the grass immediately after mowing can wash away weed seeds or prevent them from germinating, reducing the chances of weed infestations.

Enhanced visual appeal

Watering your lawn after mowing can instantly improve its visual appeal. The combination of freshly cut grass and the sparkling effect of water droplets can create a picturesque and well-maintained appearance, adding to the overall aesthetics of your outdoor space.

Potential Drawbacks of Watering After Mowing

Sufficient rainfall or irrigation

If your lawn has recently received ample rainfall or irrigation, watering immediately after mowing may not be necessary. It's essential to consider the moisture levels in the soil before deciding to water. Overwatering can lead to waterlogged soil, which can be a threat to the health of your grass.

Risk of fungal diseases

Watering immediately after mowing can create excess moisture on the grass blades and the thatch layer, increasing the risk of fungal diseases. If you notice signs of fungal issues or your lawn is prone to such conditions, it's best to avoid watering after mowing or adjust your watering schedule accordingly.

Time and resource constraints

Watering your lawn after mowing requires additional time and resources. If you have a tight schedule or limited access to water, you may prioritise other lawn care activities over post-mowing watering. In such cases, ensuring regular and proper watering at different times can still maintain the health of your lawn.

Water conservation efforts

In regions experiencing water scarcity or during water restrictions, it's essential to conserve water. You can contribute to water conservation efforts if you can maintain a healthy lawn without watering after mowing.

Established lawn with deep roots

If you have an established lawn with deep root systems, the grass may have better access to moisture stored deeper in the soil. In such cases, watering immediately after mowing may not be necessary as the roots can effectively extract moisture from lower soil layers.

Grass Species and climate considerations

Different grass species have varying water requirements. Understanding the specific needs of your grass type and considering the local climate can help determine if watering after mowing is beneficial or unnecessary. Some grasses may naturally tolerate drier conditions, while others require more frequent watering.

Determining Whether to Water Lawns After Mowing

Before you grab the hose and start watering your lawn after mowing, take a moment to consider a few essential factors. These considerations will help you make the right decision about whether your lawn truly needs extra hydration.

Soil moisture levels

Take a screwdriver or a soil moisture metre and stick it into the ground. If it goes in easily and comes out damp, your soil likely has sufficient moisture. In such cases, watering immediately after mowing may not be necessary.

Recent rainfall or irrigation

Mother Nature might have already done the watering for you. If your lawn has recently experienced good rainfall or if you've irrigated it within the past few days, there may be no urgent need to water it after mowing. Remember that moderation is crucial when it comes to watering your lawn.

Grass resilience

Consider the resilience of your grass. If you have a well-established lawn with deep-rooted grass, it has better access to moisture stored deeper in the soil. In such cases, the grass can often withstand short periods without immediate watering after mowing.

Grass species and climate

Different grass species have different water requirements, and your local climate also plays a significant role. Some grasses are naturally more drought-tolerant and can go long without water, while others require more frequent watering. Understand the specific needs of your grass type and consider your region's climate.

Time and resource constraints

Let's face it, nowadays, the majority of us all lead busy lives. Watering your lawn after mowing requires additional time and resources. If you have limited access to water, you may need to prioritise other lawn care activities over post-mowing watering. Ensuring regular and proper watering at other times can still keep your lawn in good shape.

Environmental considerations

Water is a precious commodity, and conserving it is crucial. If you live in a place experiencing water scarcity or during water restrictions, it's essential to be mindful of your water usage. If your lawn is healthy and thriving without watering after lawn mowing, it's a time-saver and an eco-friendly choice.

Water Conservation Tips To Maintain Healthy Lawns

If you decide that it is necessary to water your grass after mowing, maximising water efficiency is vital to conserve this valuable resource. Here are some handy tips to guide you on maintaining a healthy lawn while minimising water waste.

Water in the early morning

Water your lawn while the temperatures are cooler and evaporation rates are lower. This allows the grass blades to absorb the moisture before the day's heat sets in, reducing water loss.

Water deeply and infrequently

Aim for deep watering sessions instead of frequent shallow watering. This encourages the grassroots to grow deeper, making them more resilient to drought conditions. Watering deeply prevents surface runoff and ensures the water reaches the root zone.

Use proper irrigation techniques

Invest in efficient irrigation methods like drip irrigation or sprinkler systems with adjustable settings. These tools help deliver water directly to the target areas, minimising wastage.

Monitor soil moisture

Keep an eye on the levels of moisture in your soil. Use a moisture metre or feel the soil with your hands to determine if watering is needed. Avoid overwatering, which can lead to shallow root growth and water runoff.

Consider watering zones

Divide your lawn into different watering zones based on the water needs of specific areas. For example, sunny spots may require more frequent watering, while shaded areas may need less. By targeting watering to particular zones, you can avoid wasting water in places that don't need it.

Consider using rain barrels

Consider using rain barrels to store rainwater for later use in lawn watering. This helps reduce your reliance on the municipal water supply and saves you money on your water bill.

Take Charge of Your Lawn's Health

Now that you know the relationship between watering and mowing your lawn, it's time to take charge of your lawn's health. If you're still asking yourself, 'How and when to water my lawn?' assess the specific needs of your grass, consider the factors at play, and make informed decisions about watering after mowing. 

Remember to prioritise water conservation and adopt efficient irrigation techniques. With a well-maintained and adequately watered lawn, you'll enjoy the benefits of a healthy outdoor space. So give your lawn the care it deserves and watch it flourish! For best results, consider working with professionals who use high-quality lawnmowers.
