Should I Water After Fertilizing the Lawn? (Important Info)

Time and again you’ve heard that if the grass appears greener on the other side, chances are you’re not taking good care of your grass. And if the lawn on the other side appears greener, thicker and healthier, chances are you’re not giving your lawn enough attention. I just invented that, but it’s a fact.

If you’re searching on why lawn turns yellow, what you really need is tips on how to keep your lawn healthy. And on the top of the list of keeping your lawn appealing is using the best lawn fertilizer you can get your hands and watering your lawn frequently. 

In this article, we will talk about how to water your lawn after fertilizing it and answer commonly asked questions in the sector. 

So Should I Water After Fertilizing?

One of the major dilemmas that many lawn owners have is whether or not they should water the lawn after fertilizing it. The short answer is Yes, it’s crucial to water your lawn after fertilizing it to allow the soil to absorb it, especially when you’re using a fertilizer with big granules. 

If you fail to water the lawn, your fertilizer will sit on the top, and may even be washed away if it rains. It will also take longer for your fertilizer to dissolve into the soil, delaying the benefits. 

After fertilizing your lawn, water it lightly to ensure your lawn feed from the nitrogen, potassium, phosphorus, and other elements of the fertilizer. 

When watering your lawn after fertilizing, you’ll need to be very cautious. You want to water your lawn enough for the soil and fertilizer to become a little moist but not too much that the water starts washing the fertilizer away or forms puddles. 

Watering the lawn also ensures that the fertilizer goes to the right parts of your lawn, and prevents it from staying at the grass blades. This way, you don’t have to worry about answers to questions like, ‘Can lawn fertilizer harm dogs?’. 

To know the right amount of water for your lawn, keep in mind that the grass needs to soak at least 4 to 6 inches a week. This means your lawn needs to soak at least 1 inch a day. In some cases where the weather is hot, the grass may need to soak at least 21/2 inches a day. 

Fertilizing Dangers

It’s important to practice lawn care, but you don’t want your lawn and garden to exist at the expense of others. Fertilizers are good when well used, but without caution, they can become hazardous. Therefore, you need to water your lawn correctly to avoid any negative consequences.

For example, not watering enough water after fertilizing your lawn could potentially harm your dog, or cause skin irritation to your kids. To protect your family, ensure you water your lawn correctly.

On the other hand, excessive lawn watering after fertilizing can lead to the following:

  • Death of aquatic animals. Excessive watering carries away the fertilizer chemicals into water bodies. And when the lawn fertilizer ingredients are nutritious to your lawn, they’re harmful to the aquatic animals. They’re poisonous and can lead to death. 
  • Death of plants. Once the fertilizer is washed away, it’s likely to be deposited into another farm. The excessive fertilizer may kill the plants as they may not be able to hold the excess nutrients. In some cases, the nutrients may be the opposite of what the crops need.
  • Water poisoning. In some places, there are people who consume water from the river. Releasing your fertilizer may contaminate a river and harm the communities that consume the water. It’s also not uncommon for cattle owners to use river water for their animals. 

You can avoid all these dangers by watering your lawn correctly after fertilization. 

Continued Watering

After watering your post-fertilized lawn, you need to give your lawn time to absorb the nutrients by working their way into the soil. 

Give your lawn two or three days and then go back to your regular watering. On normal days, your lawn needs 1 or 11/2 inch of water per week. But how do you know you’ve achieved the one-inch depth? 

It’s really hard to tell because different sprinklers work differently. It’s important to know how a sprinkler system works to know how long it will take you to water your lawn. 

Many automatic sprinklers take approximately one hour to get to this level. Luckily, you can measure to know how long your sprinkler takes to soak your grass by one inch. This is by running your sprinkler to see how long it takes to accumulate half an inch of water in a can – just like a rain gauge does.

In most cases it will be around 20 minutes, so you’ll need to water your lawn three times a week to soak your lawn by 11/2 inches.

Avoid watering your lawn daily as it may lead to a shallow root system, which could weaken your turf. Watering 2-3 times a week gives your grass a strong root system.

Lastly, if you want your lawn to be a lawn like no other, make an effort of watering your lawn in the morning. This ensures that your lawn dries before night. This is critical for a lawn for home because a wet lawn at night can cause fungus and other diseases. 

Fertilizing and Watering Tips

Here are 5 tips to help you water and fertilizer your lawn appropriately: 

  • Invest in quality fertilizer. This is the most critical fertilizing tip. When you buy cheap fertilizer, your lawn is as good as a lawn without fertilizer. So, what lawn fertilizer works? The best lawn fertilizer is the one that has a slow release of nitrogen. This allows your lawn to benefit from the fertilizer evenly.
  • Apply the right amount of fertilizer. Your lawn needs fertilizer, but that doesn’t mean that more is better. The right amount of fertilizer helps your lawn to stay healthy and fight against diseases. On the other hand, excess fertilizer can be harmful, as we mentioned earlier. Before you add the fertilizer, read the manufacturer’s instructions to know how the lawn fertilizers work. 
  • Fertilize and watering. Water your lawn before fertilizing it as well as after fertilizing. This will ensure your lawn absorbs the fertilizer, and release the nutrients to the soil. 
  • Have a watering schedule for your lawn. Many people only water their lawns when they’re free. To make sure your lawn is getting enough water, have a routine—work towards watering your lawn 2-3 times a week.
  • Buy automatic sprinklers. Watering a lawn for garden manually can be very tiring and time-consuming. Investing in a good sprinkler will allow you to water your lawn regularly without too much trouble, within a short time.
