If you are planting a new lawn or patching an existing one with bare patches, one thing is for sure. You don’t want to wait a long time to grow the new grass. That’s why finding the best fertilizer for new grass is such an important part of the process.

In order to pick the right fertilizer for your new grass, we will take a look at what you need to know, including the differences between fresh grass and an existing lawn. Then, to help your new grass grow, we will show you some of the best products available.

Why Should I Fertilize New Grass?

If you’re wondering if fertilizing your new lawn is important, you’re not alone. Many people think that, particularly if other areas of the lawn are flourishing, new grass can grow without any support.

While without fertilizing your new lawn you can get some growth, in many instances, the nutrients that are readily available in the soil are not adequate to sustain new growth, whether you are planting seed or laying sod.

Soil that does not have enough nutrients, which can cause a lot of dust and erosion, can contribute to patchy growth and thin grass. It helps to come in lush and thick with a good fertilizer for new grass and maintains the growth in the long run.

If there is a distinction between fertilizer for new grass and standard lawn fertilizer, you might be wondering. The response is yes, it’s there. New growth has different requirements than existing lawns, which is why new seeds may not grow well even though there is grass around them.

Potassium, phosphorus, and nitrogen are found in standard fertilizers, usually in a 1-2-1 proportion. But new grass requires more phosphorus to help the seed germinate and grow rapidly than these fertilizers offer, as well as quick-release nitrogen.

What are the most important nutrients for a new lawn?

While new growth needs the same nutrients as existing grass, different quantities are needed and for slightly different reasons.

You should always look at the nitrogen and phosphorus when selecting a fertilizer. Ratio and potassium or NPK. The primary things that plants need to grow are these three nutrients. They are present in most soils, but adding fertilizer ensures that no deficiencies are present.

Nitrogen encourages good overall growth and is important for the deep, dark green that you’re used to seeing to improve your lawn. Potassium makes plants strong and more resistant to severe conditions, such as drought, disease, and prolonged hot or cold conditions.

Phosphorus is especially important for new growth, as described, and here’s why: it is necessary for root growth. For your new grass to grow, a strong root system that develops early on is essential. Plus, a deficiency of phosphorus results in overall slow growth.

Quick-release nitrogen and phosphorus are the two big factors to look for in fertilizer for new grass. This helps your grass, above and below ground, grow fast and solid.

When should new grass be fertilized for the best results?

Before you even spread the seed or lay turf, the perfect time to fertilize new grass is to Prepare the field that you will be planting, then apply the fertilizer.

Each item is a little different, so follow the directions for whatever fertilizer you want. Some formulations must be watered in, while others must first be worked into the top few inches of soil.

How to Fertilize New Grass?

The technique you use to fertilize your new grass depends very heavily on the kind you pick. That said, to keep in mind, here are some general guidelines.

Take the time to make the area ready before you start planting a new lawn. Remove any debris, leaves, or rocks, and rake the field to break up and clumpy soil. By filling in low places, try leveling the field.

It is best not to apply any weed killer yet, as the initial growth may be affected. That said, if you pick a fertilizer that contains a weed killer since it is specially designed to function in this way, you should be perfect.

Next, to coat the region uniformly in granular fertilizer, use a lawn spreader. You should be told by the packaging what settings to use. (Liquids can be a little different, so follow the instructions on the bottle if you’re using one).

Using the lawn spreader again after you apply the fertilizer to make sure the grass seed is dispersed uniformly over the field to be planted. You should be in a position to find the settings on the seed packaging label.

Rake the field again, around 1⁄4 inch under the surface, to work the seeds into the soil. Make sure you don’t go too far. Grass seeds need light to grow, so they should still be near the surface.

An integral aspect of fertilizing a new lawn is watering. While some fertilizers suggest that they do not have to be watered, to allow the grass to grow, you have to keep the ground moist.

At all times, the planted area should be moist, but you also have to be vigilant to prevent puddles. If you have to, keep the top 1⁄2 inch of the soil moist, watering twice a day. This not only gives the seeds the moisture they need to start growing, but some granulated fertilizers are enabled as well.

Until the grass is filled in and grown tall enough to be mown, keep watering at this pace. Fertilize and water as you would an existing lawn from that point on.

How To Fertilize Fresh Grass Often?

You can only fertilize fresh grass once, right before you spread the seed, in most cases. The nutrients in it can harm existing lawns because fertilizer for new grass is different from normal fertilizer.

The majority of new grass fertilizers tell you how long the product will be effective. Some last as long as eight to twelve weeks, so you can have some time to think about fertilizing again before you have to.

Generally, before adding more fertilizer, you can wait at least six weeks. Know, the lawn is no longer considered new and you can turn to a daily lawn care routine once your seeds have grown tall enough to be mown.

What is that meant to mean? Firstly, you’re not going to need to water it just as much. Lawns that have been built only require about one to 1.5 inches of water a week. Second, you can avoid using the latest lawn fertilizer and turn to a standard formula.

That said, giving your lawn a slow-release fertilizer application in the fall is a smart idea to give it a bit of support over the long, cold winter. Just make sure you do it well before the first freeze so that your lawn doesn’t get hurt.

Using your usual fertilizer in the spring, about six weeks after you’ve mown the grass a few times. If your grass still requires a bit of support when summer arrives, you can apply a slow-release fertilizer, but only when needed.
