The same is true for applying lawn fertilizer.
We tapped the experts to determine whether fertilizing before or after the next measurable rain is best.
Their recommendation will simplify your fertilizer plan and lead to a healthy, strong carpet of turf.
Time It Right
Timing is everything when it comes to fertilizer program.
Plan to spread fertilizer when the soil is warm and the grass is actively growing.
Soil temperature really does matter, says Lou Manfredini.
You want the soil temperature to be at least 50F.
This will help fertilizers and weed control to work its best.
Fertilizer timing also comes into play with the frequency of tool.
Watch the Forecast
Before fertilizing actively growing grass, check the weather report.
Turf fertilizer is available ingranular (dry) and liquid formulations.
Recommendations for when to apply vary slightly based on the fertilizer formulation.
The nitrogen-dense fertilizer will flow into waterways, disrupting the local ecosystem.
Lou Manfredini says fertilizing on a rain-free day is especially important when using liquid fertilizer.
Apply liquid fertilizer and wait about 24 hours before watering or a rain event, he says.
Bottom line:It’s best to fertilize your lawn after a rain.
For that reason, many granular turf fertilizers must be watered in after program.
Check the fertilizer package label for how-to information.
Many fertilizers are made up of soluble salts.
Fertilizer burn is most common when the turf is fertilized in hot weather or without being watered in.
Always water in fertilizer to prevent burning unless the package label directs not to.
