Indoor pottery can easily be used for your plants whether you keep them indoors or outside in a container garden.Typically, indoor pottery is simply pottery made for indoor use such as mixing bowls, coffee mugs, tea pots, cereal bowls, and milk pitchers. Your favorite dish that got a crack or chip can have a second life if you follow a few simple steps to get it ready for your plants.
Place two strips of masking tape over each other in a cross-wise pattern at the bottom of the piece of pottery. This is where you will drill through to make drainage holes for your plants. You can try other methods of growing a plant without the holes, but usually the plants will not do well without drainage.
Drill slowly and carefully through the pottery where the tape is, using a drill bit made for glass. The diamond tip is very hard and will actually scratch its way through the glaze on the outside of the pottery and then through the clay. Do not press hard or you will crack the pottery; just let it slowly scratch its way through. Two or three small quarter-inch holes will work.
Place broken bits of tile or pottery in the bottom to keep the potting soil from clogging the drainage holes. Fill the dish with damp potting soil and set the plant in place. Give it just a little more water to settle the plant in place and then place it on a drainage tray.
