What Can Be Improved?

This lawn fertilizer is suitable for use in all grass types and most lawn settings. However, it’s not an efficient lawn food in soil that is nitrogen-deficient.

Types of Fertilizer for Grass

There are many factors to check when looking for the best fertilizer for new grass, including the type of fertilizer.

Organic Fertilizers

Organic or natural lawn fertilizer is a mixture of many things, including natural minerals and plant and animal manure. This type may also contain cottonseed meal, rock phosphate, and fish by-products.

It is a slow-release fertilizer, making it ideal for applications during the fall season. It makes way for the grass to hibernate during winter and ready to bloom in spring.

Organic fertilizers are eco-friendly, and while it takes time for the grassroots to absorb them, it delivers long-term effects. However, it may attract bugs and other pets and is usually expensive.

Chemical Fertilizers

This type of lawn fertilizer features a super-concentrated mixture to enhance its absorption rate. It provides necessary nutrition for the grass much faster than organic fertilizers, making it ideal for spring applications.

Depending on the brand or specific fertilizer, it can restore the lawn in a couple of days to a few weeks. It delivers exact nutrient ratio as needed for the grass to flourish, but is susceptible to over-fertilization and may be toxic.

Ammonium Sulfate

This fertilizer lowers the soil’s pH level by providing ammonium sulfate to highly alkaline soils. It’s a chemical that grassroots absorb immediately, and it needs to dilute in water before application, although it would also be okay as top-dressing.


Urea is a type of fertilizer rich in nitrogen, made using ammonia, and offers a cost-effective solution for the yard. It’s a quick-release fertilizer and ideal for grasses that require slightly acidic soil.

However, Urea has beneficial gases that evaporate during nitrogen conversion, so it needs to get mixed with soil.

Weed and Feed

This type of fertilizer has a double purpose: It prepares the ground by killing the weeds and provides lawn food for healthier grass.

Weed and Feed fertilizers are perfect for use in lawns infected by weeds like dandelions and crabgrass. It ensures that the primary grass has enough nutrition to remain lush, abundant, and vibrantly green.

Features to Look for in the Best Fertilizer for New Grass

Lawn Starter vs. Regular Fertilizer

Grasses need different kinds of fertilizer depending on its current growth stage. Regular fertilizers provide necessary food and energy for most established grass. However, lawn starters have a special fertilizer ratio for newly emerging grass seeds, ideal for starting new lawns.

Choosing between a lawn started and regular fertilizer will primarily depend on the purpose of using the fertilizer.

NPK Ratio

The NPK ratio should be on the top priority of what to look for in lawn fertilizer. Different packs feature varying amounts of nitrogen, phosphorus, and potassium, and therefore serve different purposes.

Nitrogen-rich fertilizers are ideal for supporting overall healthy grass growth, perfect for achieving the grass blades’ deep dark green coloring. Meanwhile, potassium-rich fertilizers make grasses more robust and resistant to diseases, temperature or climate changes, and drought.

Phosphorus, on the other hand, is a necessary ingredient to boost the growth of new grass. Fertilizers rich in phosphorus help boost grass root development, and stronger roots are essential for overall grass growth.

Fertilizer Formula

After establishing the ideal NPK ratio, it’s time to choose the fertilizer formula, either granular or liquid.

Granular fertilizers are slow-release, usually taking at least a month to show visible results. However, it needs less follow-up and delivers long-lasting effects.

Meanwhile, liquid fertilizers may come in powder or liquid form, and both usually need to dilute in water. They are fast-acting but tend to require a frequent application to achieve the best possible results.


Before buying the best fertilizer for new grass, measure the lawn area first. Some fertilizer mixes are only suitable for patch treatments of small-sized yards, while others can cover up to 15,000 square feet.

Grass Type

When buying fertilizer and lawn starter mixtures, it’s essential to know what grass seeds are there.

Consider the soil’s condition to choose the ideal grass type that would thrive there. Check the pH level and the soil type, which can either be clay or sandy based. Some grass types thrive best under full sun, while others will grow better under partial shade.

Cool Season vs. Warm Season Grass Seeds

Choosing ideal grass types of lawn food mixes should also depend on the climate or temperature. There are grass types that thrive best during colder seasons, while others are ideal during warmer months.

Care Level

Different grass types will require varying degrees of care. New grass will need watering to flourish for starting a lawn, especially when using the fertilizer mix during hotter months. However, some fertilizers are low-maintenance, less watering necessary.

Frequently Ask Questions (FAQ)

What is the most effective fertilizer?

The most effective fertilizer is one that is focused on balancing the pH of your soil, as well as restoring nitrogen levels.

There are numerous lab-created fertilizers, but there are also organic fertilizers, like manure. The manure should be composted prior to use. Organic fertilizers not only recycle wastes back into food for plants, but they can also make your garden healthier by adding much-needed microorganisms.

Should you fertilize new grass?

If you have done everything to prepare the soil for your new lawn, then fertilization will give it that little extra boost.
However, if you are just planting grass seed without preparing the soil at all, fertilization is not necessary because it won’t help anything! It might actually hurt your efforts by burning out seeds before they sprout. 
There’s also a chance of fertilizer working its way into streams and waterways where it can harm aquatic life.
Remember – before using any kind of non-organic fertilizer always check with local regulatory agencies to make sure you’re not breaking any laws.

What month is best to put grass seed down?

Fall is the best month to put grass seed down because the bulk of the maintenance work in terms of putting in and maintaining a lawn can be done in autumn and winter. 
The ground will still be moist from rain; turf root systems will not yet have to compete with compaction; pH levels might actually improve since leaching will increase; weed populations will be low so less herbicide use, etc.
The two big mistakes people make are either overseeding too early – which results in bitter green weeds growing through before it gets cold enough for dormancy – or waiting until late spring when weeds are already rampant due to our scarce rainfall during the summer months.


The Scotts Turf Builder Starter Food is perfect for prepping a healthier and greener grass lawn. It can restore the yard in its former glory 35% quicker and with 70% thicker grass.

Choosing the best fertilizer for new grass is no easy task, but considering factors like fertilizer type and NPK ratios will help immensely.
