Your Zoysia Lawn: Fertilizing Established Lawns

posted on June 7th, 2010 by

Zoysia FertilizerOnce you have planted your zoysia lawn, you might be curious about how to care for it once it has become established. In this post, we will let you know what to do about fertilizing established grass plugs.

Your zoysia lawn will be its most luxurious and healthy if it is fertilized once it is actively growing in the spring before the heat of summer.  May through early June is ideal for most of the country. You should NOT use ordinary, granular fertilizers because they can burn or cause serious damage to your zoysia lawn. You must use a water-soluble fertilizer, like our Nutri-20, that has been specially formulated for use on turf grasses. Nutri-20 is great for other stuff, too, like shrubs or vegetables.

When applying fertilizer, you should apply it with a hose-end sprayer, that supplies necessary water along with the fertilizer. Always be wary of directions, carefully following the recommendations, when applying fertilizer of any kind; you don’t want to overfeed your lawn, which may result in a chemical burn.

    The Bermuda grass is still encroaching upon my Zoysia lawn. The plugs, even after fertilization with Nutri 20, are slow to spread. I have appled a second application (4 weeks apart) in hopes that I will see the desired results.

    When I used Zoysia Farms in 1977, there was no competing grasses on the developed 2 acre track. Even today, thought the property is not well kept, the established Zoysia lawn continues to thrive (I sold the property in 1988.) I know that it has worked well so I remain hopeful.

    How often can you fertilize your lawn ?

    Hi Cliff – All though Zoysia does require less maintenance than regular grasses, fertilization may be required about once a year to help speed growth and enhance color. Best done when the grass is just finished coming out of dormancy, but can be done anytime the grass is growing and not under stress (very very hot or dry).

    Is Nutri 20 safe for pets. Have cats that like to eat the grass.

    Tony – Nutri-20 is safe for pets. The amount of nutrients being applied is great for the grass, but very diluted to something like a pet. If you’d like, you can wait 24 hours and the nutrients will have been absorbed into the plant. An alternative option would be to try a new product we carry called Turf Thrive. It’s fully organic and safe for pets. Check it out here.

    Love my lawn but for some reason I am beginning to see clover starting to come in throughout my zoysia. How do I get rid of it. I have fertilized in April but what do I use to get rid of all this clover starting to come up?
    Waiting to hear from you.

    Hi Jeanne,
    You can use a broadleaf weed killer, if your lawn has been planted for at least 3 weeks, a product that is safe on zoysia grass is Weed B Gon by Ortho. If you want to prevent the clover from invading your lawn, it is best to apply a pre-emergent (not a weed & feed) in the early spring, before you see the clover. This will kill the clover seeds and keep your lawn clover free. If you have had your zoysia lawn several years and have not dethatched it, please check to make sure you are not getting a thatch build up, allowing weeds to invade the zoysia.

    We are starting a zoysia lawn. We have problems with a large variety of broad-leaf & other weeds as well as some “vining” weeds. Previously I have used Scott’s products for controlling these weeds but I understand that those products are not recommended for zoysia. What can I use that will do the same successful job without harming the zoysia?

    Hi Pat,
    You can use a broadleaf weed killer such as Weed B Gon by Ortho, please be sure to check the package label to see if the product is safe for zoysia grass and follow there instructions for application. In the early Spring you can also use a pre-emergent, this will kill the weed seeds but will not harm the zoysia grass. Please be sure to only use a pre-emergent and not a Weed N Feed, many of these are harmful to zoysia grass.

    You say that it is OK to use a pre-emergent in early Spring. Can I use the Scott’s product for this — even though I’ve always heard that their products should NOT be used on zoysia? Thanks!
