How often should I fertilize my lawn?

A nice-looking lawn can enhance the overall appearance of a home. If you want to maintain a green and healthy-looking lawn, you need to fertilize it.

Fertilizing the lawn provides it with the necessary nutrients it needs to grow well. You should, however, know when to fertilize it to get the best results.  In a year, you can fertilize the lawn between 4 and 6 times. Here is more!

The factors to consider as focus on fertilization frequency

To understand the frequency of fertilizing a lawn, you have to consider all the relevant factors. Some of them include the type of grass you have, the type of fertilizer you use, application times, how you apply this fertilizer, and how often you water the lawn. All these determine how the lawn will turn out after some time.

Frequency of fertilizing the lawn

According to experts, every homeowner needs to fertilize their lawns at least four times a year. You should not exceed fertilizing the lawn more than six times annually. Make the first fertilizer application early in the season as the grass begins to grow. This is important since it gives the grass the nutrients that it needs to develop green coloration easily.

You should also apply the fertilizer with a good organic herbicide. Apply the first batch of fertilizer when the soil temperature is about 55 degrees.  This is when grasses sprout and lilacs bloom. If you don’t know the soil temperature, you can measure it using a lawn thermometer. After the first fertilizer application, you should wait for 6-8 weeks to apply the second round of fertilizer on your lawn. You can then repeat the process twice with six weeks in between.

If you tend to forget to fertilize the lawn at the right time, feel free to schedule the applications. Ensure that you fertilize the lawn before summer to give the lawn a boost. If your lawn is established, you can fertilize it up to 4 times every season.

Apart from the frequency of fertilizing, you should remember to fertilize it when the grass is growing rapidly. When you do this, you support the growth cycle of the grass. Avoid over-fertilizing the lawn since this wastes money and increases the risk of burning the grass. Doing this can sap the nutrients in the grass and make it change color. Too much fertilizer is also not friendly to the environment since the pollutant can easily get to local streams.

Apply fertilizer based on the grass type

As you determine how often you should fertilize your lawn, you should also consider the type of climate in your area and the type of grass growing around your property. If, for instance, your lawn has cool-season grasses, you should fertilize it in late spring and early summer. You can fertilize warm-season grasses such as St. Augustine or buffalo grass in spring and then in late summer. Pay close attention to the grass. If, for instance, it looks green and thick, consider skipping feeding. 

The type of fertilizer you should use on the lawn

The market offers different types of fertilizers, including synthetic and organic ones. Organic fertilizers are better since these are natural and they come from animal or plant sources. Synthetic fertilizers are made in a lab. Though synthetic fertilizers can help the grass grow faster, they do not benefit the soil.

Even though organic fertilizers are slow releasing, they help the soil grow strong grass. You should avoid using synthetic fertilizers since they can weaken the soil and prevent the grass from sustaining itself in the absence of these fertilizers.

Check the ingredients in fertilizer before buying one for your lawn. You need to find one with healthy components such as potassium, phosphorus, and nitrogen in the right amounts. These primary nutrients are good for the grass. For instance, nitrogen can make a lawn look green fast, while phosphorus promotes root development. Apart from focusing on the type of fertilizer, you should also choose one that does not need the frequent application in a year.
