It’s best to wait until the fertilizer has been absorbed into the soil before watering your lawn. This can take anywhere from a few hours to a few days. Once the fertilizer has been watered in, you can continue to water as usual.

After you fertilize your lawn, it’s important to water it. But when and for how long? The best time to water your lawn after fertilizing is in the morning.

This gives the grass time to absorb the nutrients from the fertilizer before the hot sun evaporates them. watering for too long can also leach the nutrients out of the soil. So, how long should you water?

For most lawns, 20-30 minutes is sufficient. If you have a large lawn or if it’s very hot outside, you may need to water for longer. Check the soil before watering again to see if it’s still moist.

If not, give it another drink!

Can I Water My Lawn Immediately After Fertilizing

No, you should not water your lawn immediately after fertilizing. Fertilizer needs to be dry in order to work properly, so if you water it right away, the fertilizer will just wash away and won’t be effective. Wait at least 24 hours after applying fertilizer before watering your lawn again.

How Long Should I Wait to Water My Lawn After Fertilizing

It is best to wait 24-48 hours to water your lawn after fertilizing. This allows the fertilizer time to be absorbed into the soil and roots. If you water too soon, the fertilizer can run off the lawn and be wasted.

Is It Necessary to Water My Lawn After Fertilizing

It’s not necessary to water your lawn immediately after fertilizing, but you should do so within a day or two. Watering helps the fertilizer work its way down into the soil, where it can do the most good. It also washes away any fertilizer that might have ended up on your grass leaves, which could burn the leaves if left there for too long.

What are the Benefits of Watering My Lawn After Fertilizing

When it comes to lawn care, there are a lot of opinions out there about the best way to do things. But when it comes to watering your lawn after fertilizing, the experts all agree – it’s a good idea! Here’s why:

1. Watering helps the fertilizer reach the roots. Fertilizer is designed to nourish the roots of your grass, but it can’t do its job if it never reaches them. Watering after applying fertilizer ensures that it seeps down deep into the soil where the roots are.

2. Watering prevents burnout. If you don’t water after fertilizing, the fertilizer could end up concentrated in one spot on your lawn. This could lead to “fertilizer burn,” which is when the chemicals in fertilizer damage or kill your grass.

By watering afterwards, you help distribute the fertilizer more evenly and prevent this from happening.

When to Water After Granular Fertilizer

If you’re wondering when to water after applying granular fertilizer, the answer is pretty simple. In most cases, you’ll want to wait until the fertilizer has been absorbed into the soil before watering. This will usually take a few hours, but it can vary depending on the type of fertilizer and the conditions of your soil.

If it’s hot and dry outside, for example, the fertilizer may be absorbed more quickly than if it’s cooler and wetter.


It’s important to know when and how long to water your lawn after fertilizing. Watering immediately after fertilizing can wash away the nutrients before they have a chance to be absorbed by the grass roots. Depending on the type of fertilizer you use, you may need to water for different lengths of time.

If you’re using a granular fertilizer, you’ll need to water for longer periods of time so that the granules have a chance to dissolve. Liquid fertilizers are already in solution and will be absorbed more quickly, so you won’t need to water for as long.
