Benefits of Lawn Fertilization
When you want to achieve a thick, healthy, and vibrant lawn, fertilization can’t be overlooked. Though lawn fertilization is only one piece of the puzzle when it comes to lawn care, it provides several benefits that support the overall health of your lawn. By fertilizing your lawn properly, your lawn will get the nutrients it needs to grow. This means that the root system of your grass will be stronger, more resistant to weeds, and will have a healthier appearance.
Keep in mind that fertilizer won’t save your grass if you aren’t mowing properly or watering enough. See our post, Stop Killing Your Lawn! Common Mowing Mistakes & The Secret to the Perfect Mow Height, for tips on keeping your lawn healthy all season long.
How Often Can You Fertilize Your Lawn?
When asking the question, how often do you fertilize your lawn, you’ll likely get a wide range of answers. Though some may suggest fertilizer multiple times per year, one or two fertilizer applications, in spring or fall, will provide adequate support to a lawn that is already in good condition. If your lawn needs more help, there may be times when more fertilizer is appropriate. However, lawn renovation services may be more helpful for restoring a lawn, as an expert-led approach can address your specific concerns.
Can You Fertilize Your Lawn Too Often?
If you’ve been applying fertilizer to your lawn only to notice it looking brown, even, or possibly dead, too much fertilizer could be a culprit. We’ve often been asked, can you fertilize a lawn too often by customers trying to make sense of their lawns’ deteriorating health. Unfortunately, yes, you can fertilize a lawn too often and doing so will not help your lawn grow. In fact, it can burn your grass and weaken the overall root system of your lawn. For this reason, it is best to opt for less frequent, yet properly timed fertilizer application.
Other Lawn Care Task You’ll Want to Consider
Knowing how often lawn fertilizer should be used is only one of the many lawn care tasks you should consider to keep your lawn in top shape. Lawn aeration, lawn dethatching, and overseeding are some of the other tasks you’ll want to consider to improve and support the health of your lawn.
