I cut mine at 15/20cm but this is Australia with Santa Ana Couch, cutting low encourages lateral growth.
If you cut it higher it just gets spongy then you have to scarify

Water deep and infrequent and use a fertilizer with a higher "P" or phosphorus level. If you have an irrigation system " calibrate " it, you want to know how long it takes for each zone to equal 1" of water. Put out 5 or 6 tuna or similar containers and get an average of how long it takes to get an inch of water. You may find considerable differences between each zone and may save money on water bill. Only water when the lawn shows signs of needing water. Most grass needs about an inch a week. I have my system set to give about a half inch at 5 am and the other half inch at 7 am to keep from water run off. In the heat of the middle Georgia summer i usually have to run it about every 4 to 5 days.Old thread, I know, but I'm confused.
My grasses and climate suggest that I keep a 1.5" height. (Zoysia and Bermuda). If I allow them to grow taller, they get real funny about turning reddish and also making seed pods, which is fine but not all the time.
I can't imagine either of these grasses ever even getting 4" high, they are spreading/horizontal growers.
BUT I want to encourage deeper rooting, so I don't know what would work. The ideal cut height for both is 1.5", and believe you me, they look spectacular when it's mowed nice and tight like that.
Any advice?
