Locating the ideal flower pot in the shop, and then picking it up only to discover there are no drainage holes in the grass is a disappointing experience. Drainage is critical for plants to allow air movement around the roots and keep dirt from getting waterlogged, drowning the plant. Once a plant’s roots begin to rot, there’s usually nothing which can be done to save the plant. Fortunately, if you can use a drill, you may produce your own drainage holes, expanding your potting chances.
Determine the proper bit for your planter. Use a normal bit for plastic and metal pots, a masonry bit for unglazed ceramic pots and a glass or tile bit of glazed ceramic pots. Insert the proper 1/2-inch bit into the drill.
Expand paper on a level drilling surface. Set the pot upside down on the newspaper.
Mark the spots you plan to drill. You need a minumum of one drainage hole, which is usually put in the middle of the grass base. You may add more holes to get large-diameter pots, like three holes arranged in a triangular pattern. Keep holes at least 1 inch from the edge of the grass, and about 2 inches in the other holes.
Press a little indentation into the marked place having a nail to stop the bit from slipping away from the place on a smooth surface. If you are drilling a glazed ceramic pot, cover the drill place with a bit of painter’s tape or a couple of layers of masking tape to help keep the bit in place.
Put on safety goggles to avoid debris or dust of the grass from getting into your eyes as you drill.
Put the drill bit in the indentation you made, holding the drill so the little bit is perpendicular to the grass base. Apply light pressure as you drill at the slowest speed. Do not try and drill too fast, or you risk damaging the grass and the drill bit. Duplicate for each hole you wish to drill.
Remove the tape if you used any. Wash the drilling deposits from the pot holes.
