If your Zoysia lawn is suffering from dead spots this summer like the photo above, you aren't alone. Although Gainesville lawns have historically been St. Augustine grass, Zoysia has began making a major push as the turf of choice for a few years. With valid and proven claims of chinch bug-resistance and drought tolerance, even strict homeowner's associations like Haile Plantation that previously only allowed St. Augustine lawns have begun to allow Zoysia sod in their neighborhood.    However, it is extremely important to realize how Zoysia grass reacts to drought and what makes it drought-tolerant. It isn't that it needs less water than St. Augustine lawns or that it stays green longer than St. Augustine, either. Actually, it's quite the opposite. Zoysia actually turns brown before St. Augustine when facing drought stress and needs the same amount of water to stay green. The difference is the fact that Zoysia actually lives through the drought whereas St. Augustine will die.    To save you time and reading, a visual presentation (YouTube video) may help make a better explanation.  

That's great information to have. However, now you have brown spots in your Zoysia lawn and you want to know how to get them green again. Here is the approach I use on our client's lawns:

 

1. INCREASE WATER: If the problem is drought stress, naturally the first step would be to increase the amount of water it's getting and how long it sits on the lawn. Many people will worry about their GRU water bill at this point, but it comes down to asking yourself, "what is more important?" A green vibrant lawn or your water bill? Only you can make that choice. There are several ways to increase the water gettting to your lawn's roots: (here is a tutorial on how to change your Gainesville irrigation timer settings)
   • Increasing the frequency (watering more often)
   • Increasing the duration (minutes that the zones run)
   • Setting back the start time (running earlier in the morning so the water saturated the lawn longer before evaporation by the sun). 
2. HYDRETAIN - If the heat and drought is affecting your lawn, but the irrigation requirements or GRU bill consideration give you pause to increase your watering, the next step is to use a produsct called Hydretain. It's a product that alows your lawn to retain 50% more water than it currently does and will help your lawn utilize each ounce of water it gets to the fullest. Here is a link to learn about how it works. Long story short, it holds more moisture in the ground when in drought situations to help the grass stay healthy, and it's relatively inexpensive, too. It's only $95-$125 and lasts for 3 months (which is all we really need to make it through summer). 
3. THATCH - After you see your moisture in your soil increase, rake out the thatch from the dead areas to promote the regeneration of your Gainesville lawn. Currently, that thatch is acting like a mulch and buffer from the heat, helping to hold moisture on the soil longer and keep the soil cooler. But once the lawn starts to regrow, that thatch will actually deter it from rejuvenation. For that reason, after a few weeks of irrigation and hydretain, rake it out.
4. PEST PREVENTION - Although Zoysia is chinch bug resistant, when it faces drought stress it can get insect damage. Similar to a human's immune system being lowered, Zoysia grass loses it's pest-resistance as it gets more stressed - and that attracts the lawn pests you don't want making your problem worse. Have your lawn sprayed by a licensed lawn pest control company.

Taking those 4 steps should have your lawn rejuvenated in a few weeks. As the green returns and the summer rains get re-started, you can back the irrigation times up and begin fertilizing for the fall.

St. Augustine is a warm-season turf grass that grows well in coastal areas in southern areas of the U.S. and is a great grass for Gainesville FL sod replacement. Though it requires a little more care than other turf grasses, St. Augustine's thick, matting quality makes it a desirable lawn grass. Laying St. Augustine sod is an in-depth process, with as much preparation labor as installation to have it done correctly. Once the area is prepared and the sod laid, your grass should be ready for mowing in approximately 3-4 weeks, depending upon the Gainesville Landscaping season.

 

Step 1

Clean the area of any weeds or other vegetation before laying the St. Augustine sod. Rake the vegetation from the area, or spray it with an herbicide to kill the weeds. Wait several days for the vegetation to die before watering. Water the area after everything has died, to wash the herbicide from the surface. TMLC uses a sod cutter like they use in the sod farms to cut out approximately 1" of current grass, weeds, roots, and soil and to  ensure that the new Gainesville sod doesn't get laid higher than the rest of the lawn.

Step 2

Rake the area to remove unwanted rocks, sticks, or other debris and to smooth the surface out to be level. Laying the sod on an uneven surface will result in an uneven lawn. This also helps to loosen compacted soil so the roots tap into the soil easier.

Step 3

Sprinkle the bare ground with a low nitrogen natural fertilizer like milorganite, according to the application rates on the package. Work the fertilizer into the soil with a hard rake. This will start the eco process of microorganisms creating organic material to create a natural compost under your new sod so that it turns the florida sand (or clay) into nutrient-rich soil.

Step 4

Mark areas around trees and flowerbeds with a garden marking spray or can of spray paint. This will help you keep the sod out of areas where it is unwanted and keep a neatly defined bed line iwth firm distinction.

Step 5

Begin laying the sod down, starting at a corner. Be sure the sod lies flat upon the ground and that no piece overlaps the piece laid next to it. Kick the piece of sod with your foot to butt it up firmly against the neighboring piece. Make sure all corners are flush. Continue laying each piece of sod until you have the area covered. Some people even prefer to stagger the joints, but this is not neccessary and hasn't been proven scientifically to help the Gainesville Sod Installation process in any way. 

Step 6

Cut sod pieces to fit around curves, trees or flowerbeds, using a machete or other large knife.

Step 7

Water the newly laid sod immediately after installing. Continue keeping the area moist, but not flooded, for the next two weeks by watering daily (unless in heavy shade or sun where frequency may need to be adjusted up or down). Then cut back the watering to 5x, 3x, and 2x per week in weekly increments, depending on your local weather conditions. Drier conditions will need irrigated more oftern whereas rainy conditions may not need water at all.
