Fertilizing Before vs After Rainfall - Which Is Best?

Fertilizing your lawn in Pennsylvania is a great way to ensure it has all the nutrients it needs to thrive throughout the year. However, it's important to consider the timing of fertilization, especially when it comes to rainfall. If you fertilize your lawn before heavy rain, the treatment can be washed away before your soil has a chance to absorb it. On the other hand, fertilizing your lawn after it rains is generally a good idea, as long as the grass blades are completely dry and the weather forecast indicates sunny days ahead. To make your life easier and ensure your lawn receives the right amount of fertilizer at the right time, it's recommended to enroll in a professional lawn fertilization program.


You shouldn't fertilize your lawn before heavy rain.

Timing is crucial when it comes to fertilizing your lawn, especially in relation to rainfall. While it's true that some fertilizers need to be watered in to activate and reach the roots of your grass, heavy rain can actually wash the product away before your soil has a chance to absorb it. This means that the nutrients your lawn needs to thrive may end up being carried away by the rainwater, leaving your grass without the necessary nourishment.

When the fertilizer is washed away, it can also lead to environmental issues. The excess nutrients from the fertilizer can find their way into nearby water bodies, causing pollution and harming aquatic life. Because of this, it's best to avoid fertilizing before heavy rain.

If the forecast only calls for light rain, it is generally okay to fertilize your lawn beforehand.

Fertilizing your lawn after it rains is ideal, but there are a few things to keep in mind. Firstly, make sure that the grass blades are completely dry before applying the fertilizer. This is important for avoiding issues like uneven nutrient distribution, runoff, and fertilizer burn. Additionally, it's important to check the weather forecast to ensure that it will be sunny for a few days after you apply the fertilizer. This is because the sun helps to break it down and release the nutrients into the soil, plus it helps your grass to absorb it better.
