A Basic Understanding Of Lawn Fertilizer Ingredients

Every homeowner with a lawn wants it to be lush, right? If you're such a homeowner, you probably know that you need to water and mow the lawn regularly to keep it looking healthy. However, you also need to fertilize your lawn because not all locales are ideal for year-round lawn growth.

So, fertilizer helps your lawn and other plants thrive. Have you ever wondered how the ingredients work, though? Find out what fertilizer ingredients do for your plants.


Potassium is one of the macronutrients that plants such as grass need to undergo photosynthesis. Potassium helps grass specifically withstand stress such as drought and disease. It helps the blades maintain turgor pressure even when water is low. Potassium is also important in the regulation of other processes, such as the plant's ability to efficiently utilize another macro-nutrient, nitrogen.

A sign of low potassium in your lawn is a dried-out appearance because the blades have difficulty maintaining that turgor pressure.


Speaking of nitrogen, it's one of the building blocks of all plant cells such as amino acids and chlorophyll. Plants absorb nitrogen from the soil through their root systems and use it to stimulate their growth and reproduction. Nitrogen also helps grass grow more rapidly and show a deeper green color. Nitrogen is especially useful for spring green-up when the lawn recovers from the cold.

Grass that's lacking in nitrogen will appear stunted and yellow.


Phosphorous is the nutrient plants need for photosynthesis, which is the reaction that allows them to convert carbon dioxide and water into simple sugars. Phosphorous also helps plants transfer nutrients throughout their cells. Plants need phosphorous to make their own oils, sugars, and starches, all of which are essential for their nutrition. In grass, the nutrient promotes root growth.

Without enough phosphorous, grass may succumb more easily to disease. It will also fail to grow robust.

Other Ingredients

Fertilizer can also incorporate other elements to promote plant growth. For one, calcium is necessary for general plant vigor and to promote root growth. In grass, calcium promotes the growth of young shoots.

Magnesium is another component you find in some fertilizers. This nutrient helps plants regulate the uptake of their other necessary nutrients. Magnesium is important for plants to be able to make seeds. In grass, the nutrient promotes depth of color.

Finally, sulfur is another nutrient that helps with color. The application of sulfur also encourages vigorous plant growth.

Fertilizer comes in different formulas according to how much of the above nutrients it contains. Contact a lawn fertilization service to determine what fertilizer your grass needs.

Learning About Embracing The Natural Landscape

Hello, my name is Whitney Lovette. The property surrounding my home has a ton of natural hills and valleys that make mowing difficult. For a long time, I toyed with the thought of pulling all the grass and having an excavation team regrade my lawn. After some serious thought, I decided to take a different route and create a meandering garden space. The path through the garden takes advantage of the natural landscape to create a magical space for total relaxation. My site will cover the garden construction and upkeep process from beginning to end. Thank you for visiting my website.
