Lucky, I have worked with synthetic turf, you know looking after tennis courts and such and there is cheap synthetics and there are exxy ones.
The one I used to prepare for play, was designed as such… the length of the turf could be controlled by the use of sand. Each “grass blade” was quite long and a base of sand had to be rolled into the surface in order for the “grass” to stand up, this took some work with a “level-lad” and a heap of sweeping, not unlike top-dressing your turf after renovation work.
Watch the Hockey from the Pines on tele one day and each time the Hockeyroos take a swing at the ball, you will see a small spray of sand (looks like water).
Because of this sand, you do need to keep an eye out for fungal attack in moist shady areas, and a anti-fungal treatment was sometimes required. You didn’t want your tennis player going down on one knee, scraping oneself and copping an infection.
Once a year, you could really go hard with a big arsed vacuum and some stiff Bass Brooms and bring up some of the sand, and then re-dress and re-level.
Eventually we ripped it up and put down re-bound ace. Still, I would have loved to had replaced it with turf, much more fun to look after. But the court I looked after was surrounded by lovely tall deciduous trees that would have sucked too much water from the turf and provided too much shade.
