Protecting Against Weeds and Pests

posted on July 18th, 2012 by


One of Zoysia’s most attractive features is it’s resiliency to weeds. Unlike other grasses, Zoysia grows out along the ground. It sends out root stalks, or stolons, that create a thick carpet of grass in your yard. This is not only makes Zoysia lush and beautiful, but helps it to choke out most weeds.

In the event that a weed does manage to grow, a few sprays from Weed Be Gone or a similar water soluble product will make quick work of the pesky plants. Make sure you don’t use Roundup, it’s designed to kill grass! Always read labels carefully before applying any product.

If you start to have issues with crabgrass, your best bet is to use a pre-emergent to kill the crabgrass seed before it has a chance to germinate. Our Gluten–8 Organic Herbicide is a great product for this. For the best results, pre-emergence products should be used in early spring and again in the fall.


You guessed it, Zoysia is very resilient to most lawn pests, with only a few exceptions. This lets you avoid the cost, time and risk of using pesticides. The few pests that can sometimes pester your Zoysia are grubs, mole crickets, cinch bugs and nematodes, especially when the plugs are still new.

If you have a history of dealing with the mentioned pests, it would be a good idea to treat your lawn for them before planting plugs. If you have treat for them after your lawn has been planted, don’t worry, Zoysia isn’t bothered by the chemicals used.

  5. How do I treat ground pearls in my zoysia lawn

  6. Should I replug areas that have been affected by these pests

  7. Hi Ed,
    If the area is thin or bare, you can either replug the area or since zoysia grass is a spreading grass it will mend itself over time. Be sure to treat the area for these pest or they will keep eating the roots of your grass and continue to destroy it.

  8. Hi Ed,
    This is a tough one, there is no practical management strategies for ground pearls. The best way to compete with these pests is by adjusting fertilization, watering and mowing schedules to promote vigorous plant growth. Raising cutting heights to at least 1.5 inches. By reducing the stress on the grass and enchance the vigor of the grass you could possilby reduce the amount of damage.

  9. Thanks. I will just have to keep replugging and try to maintain a healthy lawn. Hard to do when there is no known cure. More shrubs and less lawn may be the answer!?

  10. Can I or is there anything that will kill wild bermuda that has infiltrated the zoysia??

  11. Hi Rick,
    Unfortunately, what would kill the wild bermuda will also kill your zoysia grass. Hand pulling the bermuda is about the only way to kill the bermuda without harming the zoysia. If you mositen the area before pulling, this will help you get more of the roots out. If you are very careful, you can spray the indiviual bermuda plants with a weed killer, like Round-Up, however if any gets on your zoysia grass it will also kill it.

    Can you spray Round-Up on the zoysia while it is dormant?

  13. Hi Robert,
    If the zoysia is dormant Round-Up should not harm the grass. If the grass is not dormant, green in color, then Round-Up can kill it.

    I forgot to ask if male or female dog urine will harm or discolor the zoysia grass I just ordered? Just so I know what to do with the dogs.

    Hi Steve,
    Amazoy Zoysia is more tolerant to pet urine and feces than most grasses. However, no grass will survive prolonged or constant exposure to pet wastes. Pets should be kept off of the new plugs for at least 30 days in order for the plugs to become established. After the plugs are established, you can minimize the effects of pet wastes by periodically liming the soil in order to restore the pH level to an acceptable range between 6 and 7.

    I planted Zoysia plugs last year about this time. They grew very little, but most of them did green up eventually. They are dormant now, but I am wondering when they will green up this spring? It is mid-April and I don’t see any signs yet.

  18. Hi. I am wondering if you have a service to come plant plugs or know who could

  19. Hi Nancy,
    Please give the plugs a little more time. You temperatures need to reach and maintain 70 degrees or higher for the plugs to come out of dormancy. Also, the good news is you should see a lot more spreading this year.

  20. Hi Maureen,
    I’m sorry, we do not offer this service. You may want to check with some local landscaping companies in your area and see if they offer this type of service.
