Fertilizing your lawn after the seeds germinate and sprout through the soil gives it a boost in nutrients. The nutrients often give your lawn a growth spurt. Timing is everything when it comes to lawn fertilizing, so here is what you should know about fertilizers.
How Do Lawn Fertilizers Work?
Lawn fertilizers are nutrition for your lawn. These products add a combination of potassium, nitrogen, and phosphorus to the soil that the seedlings absorb through the roots. Potassium helps your grass resist periods of little moisture and defend against diseases. Nitrogen encourages healthy blade growth to capture sunlight. Phosphorus stimulates a healthy root system. The key to effective fertilization is an appropriate release of these nutrients into the soil. Too much or too fast, and you burn the grass. Too little or too slow, and your grass starves. The conditions of the soil need to be ideal to release the nutrients and help the roots absorb the right amounts.
What Is the Best Month for Fertilizing Your Lawn?
Mid-April is typically the best time to fertilize your lawn. Plant your grass seeds in early spring to give the roots time to develop. By mid-April, you should be seeing the first new blades of grass emerging from the ground. After the first application, you can repeat the process about every six to eight weeks. Granules are the best type of fertilizer for non-professionals because you can monitor how much is being dispersed. With spray-on fertilizers, it is much more difficult to know if you are applying the right amount consistently across the lawn.
What Are the Best Weather Conditions for Fertilizing Your Lawn?
Because climate conditions are unpredictable from year to year, you should also pay attention to weather patterns before you fertilize. Mid-April may be ideal one year, yet too cold the next year. Here are some general weather and soil conditions that define when it is the best time to fertilize your lawn:
- Soil temperature should be at least 55° F consistently (the grass will also be growing from the soil)
- Outdoor temperatures should be between 80°F and 95°F or slightly cooler
- Soil moisture is congruent with the type of fertilizer -some require dry soil while others require moist soil
- Wait until after thunderstorms and rain – the excess water washes away the fertilizer
- Don’t fertilize during droughts or periods of limited watering regulations
