This is Magic! I used it to reduce grass growth upwards to be able to keep up during the high growth season in my TTTF yard.

Zoysia Grass It is slow-growing and requires less frequent mowing than other grass types. Zoysia's dense growth pattern helps suppress weeds, reducing the need for herbicides.

Growth Regulators slow the production of gibberellic acid, and thereby slow the vertical growth of your grass. So, by slowing the growth of vertical shoots, your grass will grow slower and the frequency of mowing will decrease.

You can give the lawn its first cut when the grass is 7-8cm tall (3 inches). This will encourage the plants to grow more shoots from the base and will thicken your lawn up nicely. Don't remove any more than 20% of the grass in the first cut.
