Zoysia in Summer Heat

                                           Zoysia in Summer Heat 

Looks like we may be in for another hot summer! With the temperatures reaching the 90’s and even into the 100’s it is hard to keep your grass green unless you have an Amazoy zoysia lawn. Zoysia grass loves the sunshine and heat, withstanding temperatures up to 120 degrees.  When your neighbor’s lawns are turning brown because of the heat, your zoysia will retain its lush green color. 

If you are lucky enough to have an Amazoy zoysia lawn, you know that it is very drought tolerant and stands up to the heat.  Please remember zoysia is a living thing and needs some watering in drought type conditions.  

What are drought type conditions?  This is when you have not had any rain for at least a week, your temperatures are above 90 degrees and your ground is dried out and depending on the type of soil you have even cracking.  The grass blades of the zoysia may also start to curl, this is called penciling.  These are signs that it is time to water your zoysia lawn.  Watering for about 10 to 15 minutes 2 to 3 times a week during drought conditions should be plenty for your zoysia lawn to stay healthy and green.  

During extremely warm temperatures, do not use fertilizers, insect or weed control products on your lawn.  These treatments in the extreme heat usually are not effective and can even burn your lawn.  It is best to apply theses products when your temperatures are in the low 80’s and never in the heat of the day.

    My zoysia, now well over 10 years established, has developed a large spot of decline. this started 3weeks ago ad seems to be getting worse and spreading.we’ve had very wet weather but hot and humid. Other sections of zoysia lawn, that are seperated from this probkem area, are doing very well. Whats going on and how can I fix it?
    Thank you

    Hi RJ,
    When zoysia starts to die out and has been a well established lawn, it is usually one of three conditions. One is a thatch buildup, if you do not dethatch your lawn once a year, the thatch can build over time and start choking the zoysia out and eventually killing it. The second reason, which I think may be your issue, is an insect problem, such as grubs, mole crickets, chinch bugs, etc. These insects will eat the roots of lawn grasses, killing the grass. Check a small section of the green grass as close to the brown grass as you can get, making sure you are going at least a few inches down into the soil. The third could be a fungus or disease starting in your lawn.

    I just sodded my lawn 1st week of June with zoysia, it is doing very well with exception of few spots spread throughout the lawn with brown patches. I will be sanding the lawn soon to even out the low spots, will aerating the lawn before fall be a good thing or is this to early on a new lawn? I would also like any advice on a new zoysia lawn.

    Hello Rob,
    If the brown spots are getting larger, I would suggest checking to make sure you do not have an insect problem. If the spots are not increasing, it may be that there were air pockets left under the sod and has prevented the sod from taking a roothold. You should be fine to areate the new lawn in early fall, since it was sodded.
