Do pot feet actually do anything?

Short answer
Yes, but not for the reason usually given. Pot feet do not make compost drain faster — the compost drains at its own rate. They stop the drainage hole being sealed against paving, stop the pot wicking water back up, let air reach the base, and keep the pot out of standing water in winter. That is worth having.
A pot standing flat on a paving slab has its drainage hole pressed against a wet, flat surface. Water leaves it slowly by capillary action rather than freely, and when it rains the pot sits in whatever the paving holds. Lifting it 20mm changes that completely, and costs nothing.
Step by step
- Understand what the feet actually do.They break the water seal at the drainage hole, allow air under the pot so the base can dry, prevent the pot standing in a puddle, and stop root growth out of the hole into the joints of the paving.
- Understand what they do not do.They do not speed up drainage through the compost, they do not fix a compost that is too fine or too wet, and they do not compensate for having no drainage hole.
- Use them all year on any pot standing on a hard surface.Paving, decking, concrete and, especially, a balcony. The pot dries underneath, the surface below it does not stay permanently wet and green, and decking under a raised pot lasts far longer.
- Use them without exception through winter.Winter wet, not winter cold, is what kills most container plants and cracks most terracotta pots. Raising the pot and taking the saucer away are the two highest-value winter actions there are.
- Substitute anything hard and non-absorbent.Three offcuts of tile, slate, engineering brick, treated batten, upturned plastic pot rims or bottle caps all work identically. Sold pot feet are decorative rather than functional.
- Use three, not four.Three points always sit flat on an uneven surface. Four leaves the pot rocking, which concentrates load on two of them and cracks the rim of the base.
Tips
- On a pot standing on soil rather than paving, feet matter much less — the soil drains. What matters there is that the hole is not silted up or plugged with a root.
- Feet also make it far easier to get a sack truck or a strap under a heavy pot when you need to move it.
- A pot on feet in summer dries out faster than the same pot flat on the ground. That is the correct trade — put a saucer under it in a heatwave if it needs one, and remove it in autumn.
Common mistakes
- Leaving a saucer under a pot on feet all winter — It cancels the benefit entirely and holds standing water directly under the drainage hole, which is the exact condition the feet were fitted to prevent.
- Using absorbent feet such as soft brick or untreated softwood — They soak up water and hold it against the pot base. Anything used as a foot needs to be dense and non-absorbent.
Questions people ask
Do pot feet stop vine weevil?
No. Adult vine weevils climb well and lay eggs on the compost surface. Mesh over the drainage hole and nematode drenches are the container controls that matter.
Should indoor pots be raised too?
Indoors the issue is the saucer, not the ground. A layer of gravel in the saucer that keeps the pot base above standing water does the same job.
