What is Zoysia Grass?

Zoysia grass is a type of turf-grass that can be found in the southern and southeastern United States. It has been popular in the US since the 1950s. It’s easy to weed and maintain, and is known for its durability, tolerance to drought and shade, as well as resistance to pests and disease.

As with any lawn or garden plant, it needs fertilizer too!

How to Know If You Have It

Zoysia grass is regarded as one of the best types of lawn to have because it has a fine texture, delicate feel, and slow growth pattern. It can form dense mats and mounds that grow on top of low features. It’s a type of grass that grows in small blades. It is used to make carpet-like or cushioned surfaces/turf. It needs a lot of water, takes a long time to grow, and frequent mowing is required.

Zoysia Grass requires less fertilization and is typically less susceptible to insect and fungus damage than St. Augustine Grass and Bermuda Grass.

What is Fertilizer, And How Does It Work?

Fertilizers are any substances added to the ground soil or plant tissue that can nourish plants and help them grow and remain healthy. There are several distinct sorts of fertilizer, and they’re used in a variety of settings. The finest fertilizers will feed your lawn and garden with essential minerals to allow your plants to thrive.

Fertilizers promote plant growth by giving nutrients to the plants that they require and can utilize to grow. Fertilizers include primarily nitrogen, which stimulates leaf development, phosphorus, which promotes root development, flowers, seeds, and fruit growth, and potassium, which promotes stem development.

There are also calcium, magnesium, and sulfur as the three secondary macronutrients, in addition to many micronutrients including copper, iron, manganese, zinc, and boron.

Why You Need A Fertilizer For Zoysia Grass

Zoysia Grass is a slower grass to grow than many other lawn grasses, so it is necessary that you feed and nurture it well. Fertilizing your Zoysia lawn on a regular basis will provide you with a thick and dense carpet of soft but durable grass. It will also give your grass a deep and vibrant green color that can last almost the whole growing season, and fertilizer also helps Zoysia grass conserve water, which saves you time and energy and can drought-proof your lawn.

When To Fertilize Zoysia Grass

It may be tempting to feed your plants as soon as they have been exposed to the sun. However, excessive fertilization can damage them. You don’t want to overdo it, either.

Be careful that you don’t fertilize your Zoysia Grass too early. You will promote the growth of zoysia grass blades when zoysia roots are still growing, and when early blade development is susceptible to late-season freeze damage.

Season

You should first fertilize toward the middle of spring. Because Zoysia grass is a warm-season grass, you want to wait until the soil temperature hovers around or above 60-65 degrees F.

Then, fertilize again in the middle of summer, maybe in early July. Use a lawn fertilizer with a slow-release form of nitrogen, and apply it at a rate of 1 pound of nitrogen (from the NPK ratio) per 1000 square feet. Do a quick watering after any feeding.

You can do a final fertilizing around the beginning to middle of September. In the winter, avoid fertilizing zoysia grass.

Frequency

Be sure to follow the directions on the label for whichever fertilizer you use. Some are weekly applications, and some are only once every 10 weeks or two months.

The Different Types of Fertilizer

Fertilizer can come in many different types and brands and models. For example, there are both organic and inorganic fertilizers.

Inorganic or manufactured fertilizers are made from nitrogen, phosphorus, and potassium chemicals produced by industrial processes. The nutrients in these fertilizers are highly concentrated and targeted at the plants’ unique demands, rather than being diluted.

Organic fertilizers contain less NPK macronutrients, but they do provide organic matter to the soil, which aids in the drainage and utilization of water by working in tandem with living microorganisms. Examples of organic fertilizers are compost, manure, and various types of animal and plant meals.

You can also differentiate between granular and liquid fertilizers, fertilizers with a slow-release formula or a quick-release one, and many fertilizers have different and unique NPK ratios.

Granular Vs. Liquid

Granular fertilizer is available in granular or powdered form and may be sprinkled on your grass. Granular fertilizers, unlike liquid ones, require manual application and mixing into the dirt. They have a longer lifespan than liquid types that must be replenished every few weeks. You can also add these particles to the soil by pushing them in, or by doing what is referred to as ‘top dressing’. The purpose of top dressing is to sprinkle the granules over and around the root zone of the plant.

On the other hand, liquid fertilizers are made up of dry granules and liquid concentrates that must be mixed together. You may apply this kind of fertilizer to the roots of seedlings or other plants by spraying them. Overwatering of seeds specifically can cause those seeds to wilt and die. In some cases, watering the roots has little effect; whereas, liquid fertilizer applied to plant leaves directly in many situations is more successful.

Water-soluble fertilizers are frequently diluted with water before being applied to soil in order to avoid causing potentially damaging runoff if not utilized correctly.

Slow-Release Vs. Quick-Release

All of the fertilizers you will find for zoysia grass are either slow-release or quick-release, or a combination of the two. These two types of fertilizer work differently, so it is important to know which one will be better suited for your needs.

Slow-release fertilizers, which are frequently given as monthly applications, release nutrients over time in a slow manner. On the other hand, quick-release fertilizers, which are given once a week, are meant to deliver nutrients more swiftly but in lesser amounts.

As granular fertilizers are more often slow-release and liquid fertilizers more commonly quick-release, we recommend using a granular fertilizer if you need something that takes time to release nutrients into the soil or use a liquid fertilizer if you want timely results.

NPK Ratios

The nitrogen-phosphorus-potassium (N-P-K) ratio is one of the most essential factors to consider while purchasing fertilizer since they influence plant growth. NPK ratios play an important role in determining what type of fertilizer works best on different types and varieties of plants including zoysia grass, as they dictate how much nitrogen, phosphorus and potassium should go into each product according to its intended purpose.

NPK levels in fertilizers are often listed in a ratio format, such as 10-10-10 or 4-3-4. The order of the numbers is always N-P-K, so 12-4-8 means 12% nitrogen, 4% phosphorus, and 8% potassium.

It’s often a good idea to have your soil tested before applying fertilizer to see how fertile it is. You’ll learn what elements your soil may need, allowing you to apply fertilizer that directly address those needs.

Nitrogen is primarily to promote leaf and petal growth, as well as gives the green color to grass. Phosphate is a major component of roots, flowers, seeds, and fruit. It’s necessary for plant growth in every stage. Potassium, also often listed as Potash, promotes the development and growth of stems and roots, as well as water circulation in grass and vegetation.

The particles in this Professional PGF Fertilizer are so small that they will cover your grass more densely than any other type of fertilizer – twice the number of granules per area. The more particles there are, the better and more uniform the distribution will be.
