Organic lawn fertilizer

Breaking Down the Nutrients

The main job of lawn fertilizer is to offer your lawn the nutrients it needs. There are certain nutrients that different fertilizers offer that serve unique purposes.

Nitrogen is one of the most common promises of lawn fertilizers. This element is best for plant growth and development.

This is also an important factor in promoting a vivid green coloring to your yard. This will give you the bright, healthy appearance you’re looking for.

Then, there’s phosphorus. This is an important element for root growth but many organic fertilizers use viable substitutes.

The final major element included in fertilizers is potassium which is sometimes referred to as potash. This aids in root development and increases resistance to disease and drought.

Lawn fertilizers often include a variety of secondary nutrients as well. This can include calcium, oxygen, carbon, sulfur, and more.

Helping with Maintenance and Energy Consumption

Many fertilizers also aim to help you maintain a green lawn with less work and energy consumption.

This can include the promotion of green grass with less growth and a lower need for watering.

While less active growth might sound bad, it really isn’t! It allows you to have a healthy lawn without having to mow it quite as often.

Slow-Release and Quick-Release

Fertilizers are also often marked as either slow-release formulas or quick-release formulas.

Quick-release fertilizers offer immediate nutrients. They usually last up to four weeks depending on environmental conditions.

Slow-release fertilizers are made to act overtime throughout the season. They last for about 12 weeks and provide nutrients to the lawn over time.

Granulated formulas are often slow-release options while liquid fertilizers are often faster acting.
