I took a leftover piece of PVC pipe that is about the same height as the pot and drilled holes down the entire length:
Then I stuck it straight down the center of the planted pot:
If I were going for style points I would trim the top portion off so it would not be visible. But I simply do not care, I'm just glad to be able to use this pot and get my plants watered. And the water spillage is not the pot or tube's fault, I was just sloppy.
Do you have any gardening tricks to share? Do tell.
