A leak in the roof would soak the whole area in water meaning plants wouldnt necessarily grow in a straight line. Only reason plants grow in line like that is if someone planted them like that and they're being tended to.
This place is well abandoned, for the organisation of the plants, I don't know, maybe it is because of the direction of the light coming from the roof, but for the soil movement, this are just footprints of explorers, and there are also some traces of bike riders, but that's all. A lot of abandoned place are quite frequented by different kind of people... Thanks for your comment !
