TOP TIP: Flower Pot Drain Hole Cover: Just lay a coffee filter in the bottom of the pot covering the hole before filling the pot. The soil will stay in the pot and the water will still drain out because that is what coffee filters are designed to do; let water through. They last for a long time, too; by the time they fall apart, the potting soil is well packed and the plant has roots that hold the soil together.
Here is the vertical cedar fence my hubby built (with my design, lumber shopping and staining help - Im useless with a hammer though) to cover up the two hideous air conditioning units gracing our frontage. Hes awesome! Im happy. We left lots of air for the AC units to breathe so hopefully its fine.
