Want A Greener Lawn? Here’s What You Should Have In Mind

Fertilizers are created to provide plants with the much-needed elements lacking in the soil. Bear in mind that most of the elements required by plants to grow are naturally available in the soil.

We recommend applying your fertilizers at least two weeks before summer in your region. This will minimize the risk of your lawn getting damaged by the heat of fertilizers especially granules in summer.

The Basics

Sometimes these elements are not available in the right quantity for plants to share. Their absence is often as a result of being leached or being overused by the plants. Basically, there are three elements that your plants take up when they feed on fertilizer. They are Nitrogen, Phosphorus, and Potassium – in no particular order.

For a greener lawn, you need to understand the work of each of these elements.

  • Nitrogen holds the most important spot amongst these three elements. It is responsible for the green color in plants and helps them grow strong while developing thick and dense leaves.
  • Potassium and Nitrogen together make the foliage and root sturdy and enhance the plant’s resistance to drought, disease, and wear and tear.
  • Phosphorus encourages the growth of strong roots.

Many fertilizers contain these three major elements in different ratios represented by three digits such as 18-3-4. You, however, still need to determine the best ratio for your lawn.

Blend & Fertilizer Type For Your Lawn

You still need to determine the blend of fertilizer that best meets your lawn needs. All brands of fertilizer list the ratio of their major elements and each blend of the elements serve a different purpose. The soil type and topography of your lawn can be determined by getting information from your realtors or the appropriate planning authorities. With this in hand, you should know which fertilizer to get.

When it comes to choosing the right fertilizer you need to bear in mind that there are different fertilizer types for plants. However, the most common types of fertilizers include:

  • Granular (comes in slow and fast reader sub-types)
  • Synthetic fertilizer
  • Liquid fertilizer and
  • Organic fertilizer.

Now, each of the fertilizer types above is designed to be used at different times and they produce different results.

Brand & Cost

When buying fertilizers for your lawn, you need to identify popular brands that are known to work better. For instance, Scotts is a household name when it comes to fertilizers. But with brand names comes cost too.
