Large flower pots are a nice accent to your front door or patio. They can add a pop of color in a dull corner, or add a bit of greenery in a less than lively spot. While it may be tempting to fill them full of potting soil, you may want to check out this video. Over time, when the water drains out of the pots, it creates a nasty brown water that can make a mess and even stain your concrete. Check out how we prep large flower pots. We use a smaller pot in the video to make it a bit easier on us, but the steps are the same. We hope this helps, and if you have any questions, let us know!
