Q: I understand the importance of planting in pots with adequate drainage, but many of my pots don’t have holes. Every time I try to drill into the bottom of the pot, it cracks. How do I drill a drainage hole into a ceramic plant pot without cracking it?
A: The following process can be successful, but it is not guaranteed, and it is intended for adults with cordless drill competence.
Ceramic plant pot
Diamond-coated hole saw drill bit for ceramics (15mm)
Safety goggles, dust mask, gloves, towel, clean water
- Wear safety goggles, dust mask, and gloves, and follow the drill bit manufacturer’s package directions.
- Turn the pot upside down outside or in a utility sink with a towel underneath to prevent chipping the container.
- Mark the hole location(s) on the bottom of the pot.
- Use clean water to make a small puddle at the hole location to help keep the drill bit cool. You may want to trickle water as you drill, or create a water dam with putty.
- Tilt the drill bit at a 45-degree angle and cut a shallow c- shape into the pot to use a guide for the drill.
- Raise the drill bit to the vertical position and gently and slowly drill into the pot to create a hole. Be patient and pause to let the drill bit cool if needed. Don’t push hard. Let the drill do the work.
