Types Of Lawn Fertilizer

Using grass fertilizer is an effortless way to prevent pests and diseases. It also provides the nutrients required for healthy growth and reduces maintenance requirements. However, with so many fertilizers for grass in the market, determining the ideal choice can be daunting.  Being able to distinguish the different types of fertilizers available can be a big help.

There are four main categories, and they are as follows:

Time-release and slow-release fertilizer

Slow and time-release fertilizers release a small number of nutrients at a time, lasting several months before you need to feed the grass. These fertilizers are ideal if you have little time as you won’t need to feed the grass for a long time.

Generally, time-release fertilizer can be fed 6-8 weeks, depending on your watering schedule, which is significantly longer than the four weeks recommended for other fertilizers.

Granular fertilizer

These fertilizers allow the grass to harvest nutrients gradually, minimizing the chances of burning your lawn. Granular fertilizer is easy to apply and takes a long time to leach away into the soil, so your grass will be able to absorb most of the nutrients.

They come in dry pellet form that can be measured; you can easily calculate the required amount. Granular fertilizers can be natural or synthetic. They tend to be slow-release fertilizers, although you can still find time-release granular fertilizer.

Liquid and water-soluble fertilizers

Liquid fertilizer offers the most effective way to deliver nutrients to the grass roots quickly. They are applied using a hose and are fast-releasing. Most commercially available liquid fertilizers are made using inorganic compounds, so it is essential to use them sparingly. You should also check the right depth to avoid losing ammonia.

Organic and synthetic fertilizer

As the name suggests, organic fertilizers are made using living organisms or their byproducts. Synthetic formulas, on the other hand, are immediate-release chemicals used to quick greening. Organic fertilizers are recommendable, but synthetic options are just as great, so the choice is yours on what to apply on your lawn.

How To Find The Best Grass Fertilizer For Your Lawn

Although there are various types of grass fertilizer and their retailers, not all options you encounter are desirable. It is essential to choose fertilizers according to the grass and lawn you have. Nonetheless, there are various fundamental aspects to review before purchasing grass fertilizer. These include:

The NPK ratio

Understanding the numbers is the first step to choosing quality fertilizers that will nourish your lawn grass. The NPK ratio represents the percentages of essential nutrients nitrogen (N), phosphorus (P), and potassium (K). The right amount of nitrogen will help keep your grass green all year round while phosphorus is recommendable for root growth, although it can potentially contaminate water.

Potassium, on the other hand, protects your grass from drought and diseases. A standard grass fertilizer may have an NPK ratio printed as 12-0-10, which implies the formula has 12% nitrogen, no phosphorus, and 10% potassium. It is vital to choose NPK ratios based on the turf you have and climate in your area.

You can research your grass species to find the optimal ratio for these nutrients based on their unique needs. The recommended NPK ratio for grass is 4-1-2 or 3-1-2, but the choice will depend on your grass and turf. Essentially, grass requires more nitrogen and potassium than phosphorus.

Select the type

Once you know the NPK ratio your grass needs, you should proceed to choose between organic and synthetic fertilizer. Synthetic grass fertilizers often feature minerals, gasses, and waste, which is added to speed the release time. You can see the impact of synthetic fertilizer within a matter of days.

However, they carry a downside of burning your lawn (killing the grass), so you should use them cautiously. Synthetic fertilizers can also pose a threat to the environment if they leak to water supply systems. Organic fertilizer presents a safer option if you are concerned about burning the lawn.

They are made from living organisms, such as cottonseed, peat moss, bone meal, blood, guano, and more. Organic fertilizer takes longer to produce visible benefits to the grass, so you should be patient and wait a few weeks before feeding your grass more fertilizer. They also have significantly lower environmental risks.

Find your formula

Once you have decided on a type of fertilizer to feed your grass, it is time to make one more distinction. Fertilizers come in two main forms, granular and liquid or liquid-soluble powder. Granular fertilizers are slow-release options that take longer to work the magic while liquid fertilizer may are immediately released to the roots causing quick nourishment.

Liquid formulas, however, can contaminate the local water supply when used in large amounts. You should review all the compounds in the formula and watch out for leaking lead, arsenic, and cadmium to prevent long-term public health risk and algae bloom commonly found in lawns fed liquid industrial fertilizers.

Nonetheless, you can find organic liquid fertilizer, or make one devoid of high-risk contaminants. Most homeowners and landscapers use a combination of granular and liquid fertilizer during different periods of the year. Generally, liquid fertilizer is ideal when you seek rapid results, while granular are suitable for long-term nourishment. They require less-frequent follow-up and also pose a reduced risk on the environment and your lawn.
