Should You Water Your Lawn Immediately After Fertilizing?

Cultivating a healthy lawn involves several key factors, including selecting the right grass type, mowing correctly, watering adequately, and providing the necessary nutrients for optimal growth. However, figuring out the timing and sequence of these tasks can easily become overwhelming.

In this article, we address one of the most frequently asked questions in lawn care.

When to Water Your Lawn After Fertilizing

The general recommendation is to wait about 24 hours after fertilizing before watering your lawn. This waiting period allows the lawn fertilizers to settle into the soil and begin working. Afterward, give your lawn a good watering to help activate the fertilizer and ensure the essential nutrients penetrate the soil and reach the roots effectively.

However, the specific timing for watering can vary depending on the type of fertilizer used. Some grass fertilizers may require watering immediately after application, while others may recommend waiting up to 24 hours. Always refer to the instructions on your fertilizer packaging for the best results.

What About Watering Before a Fertilizer Application?

On the other hand, it's advisable to water your lawn one to two days before applying fertilizer. This watering helps moisten the soil and prepare the grass to receive fertilizer and absorb nutrients effectively.

After watering, wait until the grass has dried before application. Wet grass can cause the fertilizer to stick to the blades, potentially resulting in uneven distribution and fertilizer burn.

When to Water After Applying Granular Fertilizers

Granular fertilizers are solid, granule-form fertilizers applied directly to the soil to provide essential nutrients to plants. Watering helps dissolve the granules, allowing the roots to take up the nutrients from the soil. Depending on the specific product, you can water immediately after applying granular fertilizer to activate the product.

Watering after application also helps wash the granules off the grass blades and pavements and into the soil where they are needed most. Timing your fertilizer application before a forecasted rainfall can also be beneficial, as the rain will activate the fertilizer and wash it into the soil.

When to Water After Applying Liquid Fertilizers

Liquid lawn fertilizers are concentrated nutrient solutions often diluted with water and applied to the foliage or soil. Unlike granular fertilizers, waiting up to 24 hours after a liquid fertilizer application should be fine to ensure the plants properly absorb the nutrients. Watering too soon after applying fertilizer risks diluting the nutrients before they are taken up by the roots.

After this waiting period, return to your regular watering routine to wash away any excess fertilizer from the foliage and into the soil. Be careful not to let the fertilizer linger too long without watering, as it can scorch your grass.

Other Considerations When Watering Your Lawn After Fertilizing

Other factors can influence your watering schedule besides the type of fertilizer. For example, if you've also applied weed treatments, it's important to wait for them to dry before watering. Like fertilizers, watering too soon can wash off the chemicals before they can work, reducing their effectiveness.

Consider the weather conditions as well when deciding when to fertilize and water your lawn. Avoid fertilizing during a drought, when the grass is already stressed, which affects its ability to absorb nutrients. Similarly, avoid fertilizing before a heavy downpour, as this can wash the fertilizer off your lawn before it can be absorbed, leading to nutrient leaching that can potentially harm the environment.

Determining the right time to water your lawn after fertilizing guarantees your grass receives the necessary nutrients to thrive while reducing the risks of damage or nutrient runoff.

Slow-Release vs. Traditional Fertilizers

Additionally, whether you're using slow-release or fast-release fertilizer can also affect your timing. Slow-release fertilizers release nutrients as they dissolve gradually over time, providing consistent nutrition to your lawn.

It means you don't have to worry as much about the risks of watering too soon and leaching nutrients or watering too late that they can potentially burn your grass. Overall, it provides a bit more flexibility in your watering schedule than fast-release fertilizers.

When to Water Your Lawn After Using NutriPod® Fertilizer

NutriPod® is a revolutionary granular lawn fertilizer designed specifically for new grass plugs. Each pod consists of pre-measured granules, which is placed into the planting hole before transplanting the plugs. It dissolves slowly over time, providing a steady supply of essential nutrients to your new grass as it adapts to its new environment.

With its slow-release formula, using NutriPod® reduces the risk of runoff or leaching. It means you can worry less about timing your watering to coincide with fertilizer application. You can even water the grass plugs immediately after transplanting, which aligns with the need to keep the soil moist for 10-14 days after transplanting to aid in establishment.

Another advantage of NutriPod® is its long-lasting effects, guaranteeing nutrient availability for up to 45 days. This reduces the need for frequent applications, saving you time and effort while ensuring your new grass receives the nutrients it needs to thrive. Overall, NutriPod® offers a more convenient and reliable way to fertilize your lawn.

What's Next

After the initial watering following a fertilizer treatment, you can resume your regular watering schedule while keeping in mind some of the best watering practices. Water less often but more deeply to encourage deeper root growth, making your lawn more drought-tolerant.

We also advise watering early in the morning when it's still cool to reduce evaporation and ensure the water reaches the roots. Avoid watering mid-day when the sun is strongest, as well as at night, as excessive moisture can promote fungal growth and make your lawn more susceptible to diseases.
