Applying the best lawn fertilizer will help your lawn to grow healthier and greener. And the buying guide will help you in selecting the best fertilizer for your lawn.

A definitive guide for selecting the best lawn fertilizer for your lawn and garden

Fertilizing your lawn regularly helps your grass to recover quickly. You should water deeply a few days before application and water immediately after application to remove any fertilizer granules from the leaf blades and get them to the soil.

Looking Nutrients Deficiency

There are two ways to determine when your lawn needs fertilizer. A soil test in a visual assessment. Visually assessing the health of your lawn is the quickest and cheapest way along deficient. And nitrogen will appear like green or yellow and stunted a lawn deficient in iron will appear yellow but do not affect growth.

Phosphorous is the third most important nutrient. And its deficiency can be predictable by a dull blue-green color with purple margins and a reddish tint.

Bring the sample of your soil to a soil testing lab and you will be known about the accurate account of the amount of nutrient your lawn needed.

Granular vs. Liquid Fertilizer

Fertilizers come in a range of applications, ways, and release types. First decide, whether you choose to apply liquid or granular fertilizer. Liquid fertilizers act quickly on your lawn and they should only be applied on windless cool days. And granular products can be applied by hand, drop or broadcast spreader.

Granular weed killer fertilizers are further divided into quick-release and slow-release nitrogen. Quick-release nitrogen fertilizer gives fast results but the chance of burning the grass alone increases.

Watering instantly after applying a quick-release fertilizer is particularly vital. Slow-release fertilizers give long-lasting results and are less likely to burn your lawn.

FAQs

How much Fertilizer to put down?

The amount of fertilizer your lawn needed depends on many aspects. What type of fertilizer the square footage of the lawn is required and whether you use the space for high traffic or low traffic lawn.

According to the research, an average lawn has to obtain four pounds of nitrogen for one thousand sq. ft. per year. Some warm-season grasses such as buffalo grass perform well with only two pounds of nitrogen per 1000 sq. ft. per year.

Remember, do not apply more than one pound of nitrogen at one time meaning that applications throughout the year will be necessary.

Why Fertilizing the Lawn is Important?

By fertilizing your lawn, you’re not only going to see awesome green-up grass but also thickening of leaves and expanding of roots. So, you’re driving awesome root growth from that early fall feeding and then you’ll see your lawn start to fill in prep.

And those nutrients that we’re putting down to green up to thicken those roots are also going to be stored in these lower parts of the plants. So, when your lawn goes dormant in November/December. Then by the spring, your lawns will be one of the first to green up. Because it’s stored those nutrients it’s ready to go early spring.

Put down the fertilizer when the plants take it up and it’s going to have an awesome benefit depending on what you want from your lawn. There’s a strategy to apply. So, the early fall will be going to help with that summer recovery such as thickening up the turf. And it will last for about four or five weeks.

The second feeding is also going to recover from summer and your prep for winter and we will have a much better lawn next spring.

What Do the Numbers On the Bag of Fertilizer Stand For?

Starting a proper application of fertilizer or other lawn products. Nitrogen, phosphorus, and potassium or potash (NPK) are the weight or ratio analyses of these nutrients.

Let suppose, a starter fertilizer has 18 for nitrogen that means that 18 percent of the bag is nitrogen 24 percent phosphate, and 12 percent potassium or potash. That’s important for when you’re going to go and put an application down.

The primary goal of nitrogen is to turn the grass green and to make it grow. The second one is phosphorus, which’s really going to be designed to help root growth and root development. And the last one potash or potassium, that one’s designed just to help with the overall health of the lawn.

These are the macronutrients that you’re going to find in almost every fertilizer that you buy for your lawn. There are also several micronutrients in fertilizers which we’re not talking about here but a couple of those could be calcium or iron.

Do I Need to Water My Lawn After Fertilizing?

Water after a fertilizer application will move the particles of the leaf blades and down to the soil where they belong. Immediately watering after fertilizing activates the fertilizers and releases the nutrients into the soil for uptake by the plant.

Watering
