How to Make Holes in the Bottom of a Plastic Pot

Quck answer

Drilling holes in the bottom of a plastic pot is essential for proper drainage of plants. To do this, follow these steps:

1. Gather the necessary materials: a plastic pot, a drill with a drill bit suitable for plastic, and a marker or pencil.

2. Decide on the number and size of the holes needed based on the plant’s requirements. Generally, 3-5 holes with a diameter of 1/4 to 1/2 inch are sufficient.

3. Mark the desired locations for the holes on the bottom of the pot using the marker or pencil.

4. Place the pot on a stable surface and hold it firmly.

5. Start drilling slowly and steadily at each marked location, applying gentle pressure. Take breaks if necessary to prevent overheating.

6. Clean any plastic debris from the holes and rinse the pot thoroughly before using it for planting.

By following these steps, you will ensure proper drainage for your plants, promoting healthy growth and preventing waterlogging.


If your potted plants are suffering from root rot, besides reducing watering, what you need are drainage holes in the pot. Drainage holes ensure that excess water does not accumulate at the bottom of the pot and suffocate the roots of your plants. The easiest way to achieve plastic pot drainage is by drilling holes in your plastic planters.

Drilling Holes in Flower Pots

Plastic pots retain moisture for a longer time compared to clay, terra cotta, or other natural material pots. This is because plastic pots are less porous than organic varieties. Therefore, plastic pots, in particular, require drainage holes. Many plastic planters already come with holes. However, if you purchase a plastic pot without drainage holes, many of them have preformed circular marks that can be used as guides for drilling your own holes.

The simplest method to drill holes in plastic planters with these marks is to use a power drill with an appropriate drill bit. Select the drill bit size based on the pot’s dimensions. A 1/4-inch drill bit is suitable for pots that are 6 inches or smaller. For pots larger than 6 inches, use a 1/2-inch drill bit. Start by flipping the pot upside down on a flat surface. To stabilize the pot, you can place it on top of a towel. Position the drill bit at the center of one of the marks. Turn on the drill and apply gentle pressure. Repeat this process along the remaining marks on the pot.

Create a Hole Without a Power Drill

Is a power drill necessary to drill holes in plastic planters? No! You can also manually create drainage holes using a Phillips-head screwdriver and a hammer. Begin the project in the same way as with a power drill, by placing the pot upside down on a stable surface.

Insert the tip of the screwdriver into one of the preformed marks and use the hammer to pound it down with measured force until the screwdriver punctures the plastic. Repeat this step around the perimeter of the pot.

When There Are No Preformed Marks

Not every plastic pot, especially smaller ones, will have preformed marks to guide your hole drilling. Fortunately, drilling holes in flower pots without preformed marks is also straightforward.

To create plastic pot drainage from scratch, turn the pot upside down and use a marker to indicate where the holes should be positioned on the bottom of the pot. A single hole in the center is sufficient for pots that are 6 inches or smaller. For pots larger than 6 inches, a center hole and three evenly spaced holes around the bottom edge are needed. Once you have marked the holes, follow the steps for either the power drill or screwdriver and hammer methods of drilling drainage holes.

Regardless of the method you choose to create flower pot drainage, remember to rinse the pot after drilling to remove any plastic debris. Once the pot is clean, it is ready to be filled with soil and your plant.

Protect Surfaces With Planter Drainage Trays

After drilling holes in plastic planters, water will flow out of the pots. To protect your surfaces, especially indoors, place your plastic pots on planter drainage trays or inside decorative planters without holes. These trays and planters will collect the water that drains from your plants, keeping your surfaces dry.
