Hey! If you have old car tires, one potential use for them is to fill them with soil and plant potatoes in them, like this. As the potatoes grow, you just add another tire on top an fill it with soil. It is easy to harvest the potatoes later, since you just remove the tire and pick them up. No need to dig them out of the ground. You can also do this on your balcony if you put a plastic sheet before putting the soil in the tires. via /r/DIY https://ift.tt/2MIK1mW
