Pot feet serve two major purposes: 1) They prevent your pot from staining the surface underneath them. 2) Allow for air flow under the container which allows the soil to dry out completely between watering.
I decided I needed to add pot feet under my pots of succulents. Here are the types I tried: – Plantstand Pot Toes – Pot Risers Invisible Pot Feet – Cast Iron Plant Trolley
The great thing about the plant trolley (also called a dolly or caddy) is it allows you to move the pot easily without lifting. I decided to place this one under a larger shallow pot I have.
I like the stability of the Pot Toes, but they show quite a bit. I bought two colors and decided I liked the light grey because they blended in with the concrete better.
