When you are ready to begin fertilizing your lawn, you may wonder how the weather can affect the time you do this.
You will need to make sure you get it right as if there is too much rain, then your fertilizer could be washed away, and your grass won’t grow as expected.
Luckily, it isn’t too hard to fathom, and by the end of this guide.
You will see the answers to ‘should I fertilize my lawn before it rains? Can you fertilize in the rain, or should you wait and fertilize after rain?
Can You Fertilize Wet Grass?
Liquids are often connected to your hose, and you feed as you spread the water. Thus, with this, your grass will be wet. Weed and feed fertilizers also require wet grass to help the weed killer stick to the leaves of the weeds so they can be absorbed.
However, the issue comes with powdered and granular fertilizers. With this fertilizer application, it needs to be right so the nutrients can reach the soil.
For other types of fertilizer products, you mustn’t fertilize when your grass is wet.
How Long Should Fertilizer Be Down Before it Rains?
There are many factors regarding fertilizers and when to apply them. Not only do you have the best time of day to apply fertilizer, but you also have the right time of year when to fertilize your lawn and help it grow.
Here is a breakdown of things that can help you understand how applying fertilizer can affect your lawn in bad ways and keep it healthy. When you apply dry fertilizer to the soil, it needs watering in, so nutrients dissolve and absorb plant roots.
The best time to water after fertilizing is right after the application. The longer fertilizer sits on soil, the greater the chance of fertilizer nitrogen will burn on your grass.
Using slow-release nitrogen, organic fertilizers will help avoid this issue and may help grow your grass green. When it rains, all your yard has even coverage. So, if not expecting rain within a day or so, water your soil thoroughly but not too much.
Apply at least 1/4 or 1/2 inches of water. Make sure your grass is dry before application, as spreading fertilizer when the grass is still wet can damage or burn your lawn. Also, using fertilizers with herbicides or weed killers need 24 hours before watering in.
What is the Best Time of Day to Put Down Fertilizer?
You can find advantages of fertilizing before or after rain. Here you can see how to apply your fertilizer before or after rain properly.
Fertilize Before Rain
Before rainfall, you can use fertilizer if you expect mild or light rain to be a replacement for immediate watering. If you anticipate heavy rainfall, it’s better to fertilize several days before a downpour or wait a few days later.
Fertilizing before heavy rain means the fertilizer might run off before dissolving and consumed by your grassroots. This is truer if the land is sloped, and it can pose a threat to the environment.
Heavy rain carries fertilizer into sewer systems and can contaminate the local environment with groundwater, reservoirs, and other bodies of water along with local wildlife and plants.
Fertilize After the Rain
From the environment’s perspective, fertilizer application after rain is better, as it won’t wash away, and the soil is ideal for the nitrogen and nutrients to soak in.
Before spreading fertilizer, wait for green grass blades to dry well. Follow your fertilizer application with a soft, good 1/4- or 1/2-inch amount of even sprinkling immediately after to help it dissolve in the soil.
How Often to Water?
After the first watering of your fertilizer, wait 2 – 3 days as this allows the grassroots to absorb nutrients from the fertilizer.
Seasons can make a difference in watering and good lawn care. Here’s a quick breakdown.
Lawns need soaking to 4 to 6 inches deep per week. This needs at least one inch of water to reach deep into the root system.
Let your lawn dry before the next watering. If grass changes from green to brown, increase the water but don’t water too much. (Find the Best Tree And Shrub Fertilizer)

What Time of Day Should I Fertilize My Lawn?
When you are learning how to fertilize your lawn properly, you will want to know the best time to fertilize in the day. You already know that heavy rainfall can wash away the nutrients and cause a pollution issue in the environment.
Luckily, the time of day doesn’t present as many risks to other plants as it does to your lawn. Much of this, though it does depend on how hot it is in your yard.
It is best to apply fertilizer early in the morning before the air temperatures rise and cause the nitrogen to burn your grass.
The late evening can also be suitable, yet if your overnight temperatures drop too much, this can cause other problems.
The key is to make sure your soil can absorb the product’s nutrients before the full heat of the day.
It is best to remember not to fertilize your lawn on hot days or in drought conditions when soil lacks moisture.
With all the above, you can see the best time to fertilize your lawn and how to get the best amount of growth from lawns at any time of year.
