If there’s one thing I’ve learned from keeping houseplants, it’s that good drainage is everything. Even the toughest plants will struggle if their roots are sitting in soggy soil. That’s why I always make sure my planters have proper drainage holes. And if they don’t? No problem—I grab my drill and make them myself! Here’s exactly how I do it.
What You’ll Need
- A planter or pot without drainage holes
- A power drill
- The right drill bit for your material (ceramic, plastic, or terracotta)
- Masking tape (optional, but super helpful)
- Safety glasses (better safe than sorry!)
How do you drill drainage holes in planters?
Step 1 – Choose the Right Drill Bit
The key to success is using the correct drill bit for your pot. For plastic, a standard drill bit works fine. For ceramic or terracotta, I use a masonry bit designed for harder surfaces. Select a size that allows a hole large enough for water to escape, but not so big that all the soil washes out—I usually opt for about 1/4 inch.
Step 2 – Prep Your Pot
If your pot is ceramic or glazed, I put a piece of masking tape over the spot where I’ll drill. This helps keep the bit from slipping when I start. I also like to flip the pot upside down on a towel for a little cushioning—it makes it steadier and keeps it from wobbling around.
Step 3 – Start Drilling Slowly
Here’s the trick: don’t rush it. I hold the drill straight and start at a slow speed, letting the bit gradually bite into the surface. Pushing too hard can crack terracotta or chip ceramic, so patience is key. Once the bit gets going, you can speed it up slightly until you’ve drilled all the way through.
Step 4 – Add Extra Holes if Needed
Most of the time, I drill one good-sized hole in the center. But for bigger pots, I’ll make three or four smaller ones spaced around the bottom. More holes mean better drainage, especially for thirsty plants like succulents and cacti.
Step 5 – Clean Up and Plant Away
When I’m done, I brush away the dust or shards and check that the holes are smooth. If there are sharp edges, a little sandpaper or file takes care of it. Then it’s time to pot up my plant in fresh soil, knowing it won’t be sitting in waterlogged roots anymore.
Why I Love Drilling My Own Holes
- It gives me more freedom to use any container I like—pretty bowls, thrifted pots, even repurposed mugs.
- My plants are healthier with proper drainage.
- It’s quick, satisfying, and makes me feel like a plant DIY pro.
Now I never pass up a beautiful container just because it doesn’t have holes. With a drill and five minutes, I can make it plant-ready—and my houseplants thank me for it.
Frequently Asked Questions
How Do Some Plants Survive In A Pot Without Drainage?
Some plants are specially designed to thrive in pots without drainage. These plants don’t require as much water and have adapted to absorb the necessary nutrients from their environment.

Do plant containers need drainage holes?
Yes, plant containers usually need drainage holes. These holes allow excess water to flow out, preventing root rot and other diseases caused by over-saturated soil. However, if you’re growing plants indoors or in areas where it’s difficult to contain the runoff, consider planting in a pot without drainage holes instead. With these special plants, you don’t have to worry about over-watering and can still enjoy the benefits of a healthy, thriving garden.
Why do some plants need drainage holes?
Plants need drainage holes because they are prone to root rot and other diseases caused by over-saturated soil. Excess water will accumulate in the bottom of a pot without drainage, preventing air and moisture from reaching the roots. By having drainage holes, excess water can flow out and away from your plants – reducing the risk of disease.
Why do some pots not have holes?
Some pots do not have holes because they are designed to contain water. This is especially important for indoor plants or those grown in areas where it’s difficult to contain runoff. Without drainage holes, you can still grow these types of plants – make sure to use an extra layer of material at the bottom and take measures to prevent over-watering.
Do indoor plants need saucers?
Indoor plants need saucers or drip trays to catch excess water. This is especially important if you are growing your plants in a pot without drainage holes, as it helps prevent the roots from becoming over-saturated and reduces the risk of disease. Additionally, using a saucer with adequate drainage can help ensure that your plant has access to the right amount of water and air, allowing it to thrive.
