Applying Lawn Fertilizer in Summer
When it comes to applying your lawn fertilizer during the summer, there are important things to know. You should ask yourself what type of grass you have, what the climate is, what fertilizer you prefer, and how you want the lawn to look.
Every part of the country has a different climate. For example, in Illinois, it’s very humid and hot, with temperatures that fluctuate throughout the day. In places like Idaho, the temperatures are relatively unchanging, and there is much less humidity.
The climate can make a difference in how the fertilizer works. Also, you may have a different grass type because of the environment in which you live.
Warm-season and cool-season grasses are the primary types. Of course, warm-season grasses can include Zoysia and Bermuda.
They thrive and become very green during the summer. Plus, they are creeping grasses, so they spread across the lawn and look like vines.
Generally, these grasses have brown leaves during the fall. However, they green up again in the spring and summer. Right before that greening happens, you need to apply the fertilizer.
With cool-season grasses, you may find they can withstand the temperature changes. They also have a bigger tolerance for drought and disease. Examples of cool-season grasses can include rye, fescue, and bluegrass.
Often, they green-up and grow more in the spring or the fall. They’re dormant in winter and summer. This means that they don’t need a lot of fertilizer in the summer.
You should still apply fertilizer to the grass. However, these grasses aren’t going to need as much nitrogen, especially during the summer. If you do use it, the grass could get burned or be put under undue stress.
Fertilizer Types and Options
There are two primary fertilizer options: organic and synthetic. Synthetic fertilizers are manmade and can give your lawn a fast boost because it releases the nutrients right into the soil. This type of fertilizer has three components.
Nitrogen is there to support healthy leaves and stems. Potassium ensures that there is a balance of water within the plant. Phosphorus can help your grass develop deeper, stronger roots.
The container or bag is going to show numbers associated with these nutrients, called the NPK number. Of course, there can also be other ingredients included. These consist of calcium, magnesium, sulfur, and iron.
Organic fertilizers feature natural ingredients and sources, such as fish meal, compost, or manure. They also use the NPK system. Many people like the fact that it is natural and can be safer around pets and children.
Still, most people believe that organic fertilizer is a soil conditioner instead of grass fertilizer. While this can be beneficial in the long-run, it isn’t going to help you green up your grass for that season.
Cool-season grasses often respond better to organic fertilizer if it is to be applied during the summer months. It doesn’t burn or stress the lawn. Synthetic fertilizers should not be used on cool-season grasses in summer and must be used in the fall or spring.
Conclusion
When it comes to your lawn, you want it to look green and full. Many times, drought and other issues can cause it to appear yellow or sparse. Therefore, you need to feed it with the right fertilizer.
We think that the best fertilizer for grass in summer is Natural Liquid Fertilizer from Simple Lawn Solutions. It has a balanced formula, works on any type of grass, and is organic and safe for pets and children.
