I previously asked about Planting grass during shmita, and discovered that it is forbidden. But what about astroturf (synthetic grass)? Would there be any problem with installing that during the shmita year?
Some potential problems i can think of:
- Mar'it ayin -- people might think you planted real grass during shmita.
- It seems that some digging and watering is necessary before "planting" it, which sounds like it might be a problem.
Do any poskim address this?
