Fertilizing at the correct times of the year can help promote lush growth and keep weeds away, while applying too much or too little fertilizer can damage your lawn.
This article will discuss the best times of year to apply fertilizer for zoysia grass and what kind of fertilizer should be used.
With this information in hand, you can give your lawn all the nutrients it needs throughout the growing season!
When Should You Fertilize Zoysia Grass?
When fertilizing zoysia grass, the frequency will depend on your specific lawn and its needs.
Generally speaking, zoysia grass should be fertilized at least once every two months during the growing season. But let’s break it down by season for the sake of simplicity.
Spring Zoysia Grass Fertilization
You can fertilize your zoysia grass when the ground has thawed, and temperatures are consistently above 50 degrees Fahrenheit.
A slow-release fertilizer with a nitrogen content of 12–15% is ideal for springtime fertilization as it will provide a steady release of nutrients over time.
Summer Zoysia Grass Fertilization
Once the growing season is in full swing, it’s time to give your zoysia grass an extra boost of nutrients.
This can be done with a quick-release fertilizer that contains nitrogen, phosphorus, and potassium.
Apply this fertilizer every two months during the summer for optimal growth and health.
Fall Zoysia Grass Fertilization
To prepare your zoysia grass for winter, you’ll want to give it a final dose of fertilizer before the cold weather hits.
A slow-release fertilizer with a nitrogen content of 8–10% should be used in late fall.
This will ensure that your lawn has enough nutrients to make it through the winter months.
No matter what season you fertilize your zoysia grass in, following the instructions on the fertilizer package and water after applying is important.
What Kind of Fertilizer Is Best for Zoysia Grass?
To maximize the beauty of zoysia grass, it’s important to pick the perfect fertilizer. Zoysia grass requires regular fertilizer applications for optimum health and growth.
Fertilizers should be chosen based on the type of soil in which the grass is growing and the desired results from fertilization.
Generally, combining quick-release and slow-release nitrogen sources is best for Zoysia grass. Quick-release nitrogen sources, such as ammonium sulfate, are absorbed by the plant rapidly and may need to be applied more frequently.
Slow-release nitrogen sources, such as methylene ureas and sulfur-coated urea, release nitrogen into the soil slowly over time so the grass can absorb it.
When applying fertilizer, it’s essential to remember that a little bit goes a long way. Using too much fertilizer on your zoysia grass can be detrimental.
When used correctly, though, you’ll have the envy of the neighborhood with a lush zoysia grass lawn!
Frequently Asked Questions (FAQs)
How much fertilizer for zoysia grass?
Generally speaking, for established zoysia grass, it is recommended to apply two pounds of nitrogen per 1000 square feet of lawn seasonally.
How do I make my zoysia grass greener?
To make your zoysia grass greener, it’s important to give it the right combination of sunlight and care. Zoysia grass grows best with five to six hours of direct sun each day and needs an inch of water per week during the growing season to stay healthy. Mulch around the grass to preserve moisture in spring and early summer months, fertilize three to four times a year, and aerate your lawn annually.
Should I put sand on my zoysia grass?
We don’t recommend putting sand on zoysia grass. Sand can cause soil compaction and reduce water absorption into the root system, leading to weaker overall growth.
Are coffee grounds good for zoysia grass?
Coffee grounds can provide a steady boost of nitrogen to the soil which zoysia grass absorbs and can use for growth and development. Additionally, coffee grounds in the soil help retain moisture and mitigate acidity in the ground for healthier, more vibrant green grass over time.
How do you control weeds in zoysia grass?
To control weeds, it is important to mow your zoysia grass regularly. Pre-emergent herbicides are also helpful in keeping annual and broadleaf weeds away!
