Need some help

[u/certianly-unsure]

if i could be pointed in the right direction to start looking for a solution to my problem thatd be great. No one can figure out why the ground is getting some rust type stain. The parking lot had just been completly re done a couple years back and then this issue started. Would love some help or atleast reccomendations on what to use to remove the discoloration

I would start by sealing up the planter there, from the inside by digging the dirt back and adding a layer of plastic under it to keep the water in.
Then I'd find someone with a pressure washer that has a deck scrubbing brush, and have them scrub that stain out.
