When to Water after Granular Fertilizer?

Discover the ideal timing and methods for watering after granular fertilizer application to ensure optimal nutrient absorption and prevent plant burn in your garden.

Granular fertilizers are easy to apply and efficient in delivering nutrients uniformly; that is one of the reasons why some farmers use them. However, without adequate water, these fertilizers will not be able to dissolve in the soil and be leached with no positive effects. 

Watering after applying granular fertilizer is crucial and should be done in the right way and at the right time. 

Here, we will discuss the best time to water after you apply a granular fertilizer. 

Let’s get started!

There are several reasons why watering is important after applying a granular fertilizer. 


This type of fertilizer is in grain form, and therefore, it needs water to dissolve and release its nutrients into the soil.

Even distribution

As the fertilizer gets dissolved in water, it can be easily distributed in the soil, which adds up to a strong soil profile. 


Because of the direct contact between high N-content granular fertilizers and soil, plant burn can be seen within an hour. Watering dilutes the fertilizers and prevents burns. 

The ideal time to water after fertilization

Moisture is the key to any granular fertilizer; therefore, in many cases, you can water it after immediate application. However, many times, it also depends on the time of the day. For instance, the granular fertilizer after receiving water during the night or late evening time may create an atmosphere for fungal growth. Hence, immediate watering during nighttime may result in more bad than good. 

It’s suggested to water your after a granular fertilization session in the early morning. Because of the cooler atmosphere, fertilizer is less likely to evaporate. Hence, it reaches the soil effectively. 

And, if you are wondering how often you shall water after fertilizing it with a granular fertilizer, the answer is once every 4-6 days. But during summer, you should water it 3-4 times in 6-7 days to protect it from drought stress.  

Some alternatives to immediate watering 


In case immediate watering is not possible, here’s what you can do


Watering the soil before you apply the granular fertilizer helps create a moist environment that allows it to dissolve quickly. This eliminates the need for immediate watering up to a good extent. In some cases, the users apply fertilizers after rain; it is to be noted that only light rain creates the right conditions for fertilizer application. 

30 minutes after application

Another alternative to immediate watering is to wait for 30-35 minutes; within this time, the fertilizer starts to get moistened. That is when you can water them; any longer than this time may lead to root burn. 


Watering can be done right after a granular fertilizer is applied, but it’s important to consider factors like weather conditions and soil type. An adequate amount of moisture can help the fertilizer dissolve and distribute properly; however, excessive water can also ruin it. Therefore, it is suggested to avoid overwatering and watering during times when high rain is expected.
