When I rented I gardened. I haven't the slightest clue why you believe someone wouldn't garden when they rent. In fact the place I rented I picked because I could garden.
I do. My sister likes to garden, and when she was renting she put a lot of effort into creating a large, beautiful garden.
Then the landlord decided she needed to move her ailing mother closer and terminated my sister's lease. After that my sister didn't bother with a garden until she bought a house.
