Imagine you're wandering through a nursery and you come across a beautiful pot. Perfect size. Perfect colour. Perfectly matches that Philodendron micans on your bookshelf. There is not a pot more perfect in existence.
Does it have a drainage hole?
Here's the thing — it doesn't matter as much as you think. Hole or no hole, you can make it work. What matters more is understanding the trade-offs and setting things up accordingly.
What drainage holes actually do
A drainage hole serves one function: it lets excess water escape. Without one, water has nowhere to go except deeper into the mix, where it sits around the roots.
Most plants don't like wet feet. When the mix stays saturated, roots can't get the oxygen they need, they begin to die back, and rot sets in. That can spread through the root system and eventually take the whole plant.
You don't want root rot.
But here's what most plant content doesn't tell you: a drainage hole won't fix a dense mix sitting in low light. If your potting mix holds too much moisture and your plant isn't getting enough light to drive transpiration, water is going to sit — hole or no hole. Drainage is one part of the system — and the right potting mix drains better from the start.
When we use drainage holes
Pots with drainage holes are the most forgiving option. You can water thoroughly — we recommend watering until it runs out the bottom, which ensures the whole root ball gets an even drink — without worrying about excess pooling at the base. They're also easy to use in sinks, showers or with a bottom-watering bowl.
If you're new to indoor plants or building a low-maintenance setup, start with a pot that has drainage holes. They give you the most margin for error on watering.
When we use sleeves
Pots without drainage holes — usually called sleeves — are designed to slide over the plastic nursery pot your plant comes in. They are not designed to be potted into directly. If you pot directly into a no-hole container, excess water pools at the base and you have no way of knowing how much is sitting down there. The risk of root rot is real.
Used correctly though, sleeves are excellent. They give you flexibility — slide the plant out, take it for a soak, put it back. Swap the sleeve when you want a different look. No permanent commitment to a pot you might be bored of in six months.
What we actually do
Honestly? We rarely pot directly into any planter — hole or no hole. We keep plants in their nursery pots and use the planter as a sleeve. It usually means watering is easier, repotting is cleaner, and we can change the look of a space without disturbing the plant at all.
The setup: nursery pot inside the planter, a layer of pebbles underneath if the height needs adjusting, and a quick lift-out whenever it's time for a drink.
One thing worth knowing: pebbles at the base don't improve drainage the way people think — the research on this is pretty clear — but they're useful for getting the height right.
Need to drill a hole in a ceramic pot?
You'll need a diamond-tipped or ceramic drill bit, a rubber mat, water to keep the surface lubricated and a dust mask. Mark your centre point, start at 45 degrees to create an edge, then lift to 90 degrees and apply gentle pressure. Done in minutes — just don't rush it.
The bigger picture
Drainage holes help. But they're only one part of the system. Light, watering frequency and potting mix all determine how long moisture sticks around in the root zone. Get those three working together and you've got far more flexibility in the pots you choose — because the conditions around the plant are doing the work.

Very well written and true. I’ve seen people review sleeves having put soil and a plant right into it, and others who drilled a hole in the bottom! Seems there’s still work to be done on educating the public. I think the French refer to sleeves as a cachepot and it’s not at all a new idea. But what’s really frustrating is when you find a pot you like and it has a hole in the bottom and no saucer! Talk about confusing things.
