That’s a bit absolute—saucers under planters aren’t inherently bad, but they do come with tradeoffs.
A saucer’s main job is to catch excess water so it doesn’t damage floors, furniture, or patios. That’s useful, especially indoors. The downside is what you’re probably getting at: if water sits in the saucer and the pot reabsorbs it, the soil can stay too wet. That can lead to root rot, fungus gnats, and generally unhealthy roots for plants that prefer drying between waterings.
The key detail isn’t “never use them,” but “don’t let them turn into a permanent water reservoir.” For many plants, it’s fine if you:
- Empty the saucer after watering
- Or use it only for short drainage, then discard excess
- Or elevate the pot slightly so it drains freely without sitting in water
Some plants actually tolerate or even enjoy consistently moist conditions, so a little water in the saucer isn’t always a problem.
So the better rule is: use saucers when you need them, but don’t let standing water linger unless the plant specifically likes wet roots.
