This is probably a long shot

I live in an area where there’s no urban gardens within .75 miles. However, in the courtyard of my building there are nine planters 4 1/2 ft.² I’ve been giving permission to plant a vegetable garden. I’m low income so I was hoping, is there anybody out there that can help me out with gardening supplies such as: dirt, cococore, buckets, trowels, hoe, gloves, seeds, hanging planter anything really.

I’ve been putting as much money into it as humanly possible since I moved in. Back in October there was no dirt in the planters whatsoever. Now they’re almost all full. I want to be able to make sure that my neighborhood has access to fresh fruits and vegetables. I’m thinking globally starting locally.

Edit to add I forgot to say I fixed the Irrigation systems in them
