Mowing
Mow the lawn when it first turns green in the spring using a reel mower set at 3/4 to 1 inch or a rotary mower set as low as possible without scalping the lawn. Mow before the grass grows taller than 1 1/2 to 2 inches. Recycle nutrients by not collecting clippings unless the are unsightly or in clumps.
Fertilization
Fertilize with 1 pound of potash (K2O) using 1.6 pounds of muriate of potash (0-0- 60), 2 pounds of potassium sulfate (0-0-50), or 5 pounds of sul-po-mag (0-0-22) per thousand square feet. To determine amount of product required to apply 1 pound of potash per thousand square feet, divide 100 by the third number in the fertilizer ratio. For example, for a 6-6-12 fertilizer, divide 100 by 12. The result is 8.3 pounds of product per thousand square feet.
Irrigation
Water to a soil depth of 4 to 6 inches. Probe with a screwdriver to determine moisture depth. Zoysia grass needs a weekly application of 1 to 1 1/4 inches of water. On sandy soils, it requires more frequent watering, for example, 1/2 inch of water every third day. It is often necessary to irrigate an area for three to five hours to apply 1 inch of water. (It takes 620 gallons of water to apply 1 inch of water per thousand square feet.) Because clay soils accept water slowly, irrigate these areas until run off occurs; wait one-half hour until the water has been absorbed, and then continue irrigating until the desired depth or amount is obtained. A dark, bluish gray color, footprinting, and wilted, folded, or curled leaves indicate that it is time to water. Dormant zoysia grass may still need to be watered periodically when warm, windy weather prevails.
Weed Control
Apply preemergence or postemergence herbicides as needed to control winter annual and perennial broadleaf weeds such as chickweed and hen bit. reemergence herbicides will not control existing perennial weeds. Apply postemergence herbicides only when weeds are present.
Insect Control
Check for white grubs and control them if necessary.
** To determine amount of product required to apply 1 pound of potash per 1,000 sq. ft., divide 100 by the THIRD number on the fertilizer bag. Example: A 6-6-12 fertilizer. Dividing 100 by 12 = 8.3 pounds of product to be applied per 1,000 sq. ft. for 1 pound of potassium.
