You know that healthy, happy succulents rely on proper watering and that drainage holes are important. But you have found the cutest pot, and just know your succulents would look great in it. The only problem is that there are no drainage holes. We gardeners seem to go through stores, turning every fun container upside down, looking for signs it will be great for our succulents. Skip the angst, and learn how to drill a hole in a ceramic pot perfectly – every time. This will open up so many opportunities to decorate your home and garden, while still ensuring your succulent plants’ health.

How to Drill a Hole in Concrete or Ceramic

When you are planting succulents in containers without drainage, you have two options. To plant, and then take great care with the watering – or to drill your own drainage holes. Today, we are going to look at creating drainage in a variety of types of pots for your succulents. For wood, plastic or thin metal, use a general purpose drill bit. For concrete, clay, porcelain, tile or glazed ceramic, you will need a specialty bit. Selecting the right drill bit for drilling ceramic or concrete is important, as is your drilling technique.

You will need:

The container to be drilled – be sure you know what it is made of

3/8″  or 10mm ceramic drill bit, for glazed ceramic, tile, pottery or china

3/8″ masonry drill bit for concrete or terracotta

A piece of flat scrap wood

A piece of tile or glass jar for practice drilling holes in ceramic

Mesh drywall join tape or similar for covering drainage holes in pots

Scissors

Succulents! 🙂

How to Drill a Hole in Concrete

How to Drill a Hole in Concrete with masonry drill bit

If you have a concrete or cement container, you will need a masonry drill bit. A masonry drill bit is often tipped with carbide for longer life and durability. Unlike a general purpose bit for wood, your masonry bit will not be cutting the concrete, stone or brick, but abrading it, or wearing a hole in the material through focused friction.

To drill a hole in concrete, set the pot on a piece of scrap wood. That way, when the bit drills through the concrete, it won’t go through the top of your table. Be sure to lay the pot with the flat bottom on the wood, rather than upside down on just the rim. This way, the weight of the container, and the force of the drill bit will be spread evenly across the breadth of the container’s bottom. You won’t risk cracking or breaking the material the way you would if you drill it upside down. Set the masonry drill bit near the center, and begin to drill very slowly. To drill through concrete and avoid the risk of breaking it, slow is the key. For a small container like this, a single hole should work well. For larger containers, add additional drainage holes. Be sure to drill at least one full inch from the edge of your planter. Drain holes should be at least one inch apart.

Covering Drainage Holes in Pots

Once you have added a drainage hole to your container, now, how to keep the soil in? While there are a number of strategies, including using broken pottery shards, or coffee filters, I like to use drywall joint tape. It is a mesh tape that comes in a roll. The mesh allows water to pass, while keeping the large, gritty particles of the soil inside the pot. Very inexpensive, with a bit of adhesive on the back to keep it in place. One roll does loads of pots, and it stores away nice and tidy in my succulent care kit.

Now, just add soil and succulents!

How to Drill a Hole in a Ceramic Pot

When you will be drilling ceramic, the correct bit is crucial. Because this mug is precious to me – it was the last gift my Mother gave me – I wanted to be sure I got a good, clean hole the first time, with no breakage. So I skipped the spear point drill bits as just too iffy in their results. Instead, I selected a diamond grit tile drilling bit for drilling holes in ceramic. Not only did I get perfect results, I will be able to drill hundreds more with this same bit! Yes, I am sure my husband is thrilled! 😉


Technique for Drilling Ceramic – Start with 45 Degree Angle

Technique for Drilling Ceramic - Start with 45 Degree Angle and water on surface to be drilled

The technique for drilling ceramic with a diamond grit tile bit is a bit different from drilling wood or concrete. I recommend that you try it first on a piece of scrap tile or a glass jar to get the feel of it. You will want to use water on the drill bit and on the ceramic throughout the drilling. The will keep both the bit and the ceramic cool, and enhance the bit’s drilling action, ensuring a better hole, and longer life for the drill bit. Spray water on the ceramic where you will drill. A small puddle is great. Do not be concerned about mixing water with electricity – you’re not. The electric motor is far from the drill bit.

Set the drill bit on the ceramic pot at a 45-degree angle. Slowly, start the drill. This will be a slow process, so don’t get impatient.

Drilling Ceramic

After drilling for about 45 seconds, stop and take a look at your progress. You will have created a divot in the ceramic where the drill bit will sit comfortably, without running around on the cup. Spray with more water, and resume drilling at the 45-degree angle. Then slowly move it into an upright position, so that you are drilling at a 90-degree angle.

Continue to drill slowly. This is a study in patience, but the results are well worth it. Continue to spray with water throughout the drilling.

    1. Hi Kelly,
      Just use a ceramic drill bit. I really like the diamond grit hole saw drill bit. Always – always! – be sure to keep water on the pot and the drill bit while you use it. Don’t add too much pressure. A little patience, and you will always get a smooth, regular hole without breaking or chipping your pot! 🙂

    1. Hi Connie,
      I got mine for drilling ceramic at Home Depot, and I found the same type for a better price on Amazon here. I would assume Costco has them, too, but I don’t know for certain.
      You will be amazed at how much you use this – suddenly, EVERYthing looks like a great planter! 🙂
