I have a use for empty pop cans or empty water bottles work great too! We just have an excessive amount of carbonated water cans right now due to covid-19 and the inability to return cans right now.
I bought these giant planter pots for the deck and I don’t like filling them all the way up with dirt. Number one, they are too heavy to move around and number two, you don’t need all that dirt for flowers.
Fill the pot half way up with cans or bottles and then top off with soil, then plant your flowers!
It’s very green…recycling, it’s a money saver and a back saver!
