Chelle, first let me say, your pictures are beautiful!
I like using things like trash cans as planters. I have one trash can about the size of yours which is great for flowing plants, like nasturtiums. You've inspired me to find more! Like you said, it's an inexpensive way to pot up your plants. It's just so crazy how much money they want for planters at the garden centers and nurseries!
Great tip!
