Terracotta or plastic: which pot for which plant

24 of 100 species in this database need it

24 of our 100 species need it. How often does this plant want water? Fortnightly or less often means it wants to dry out, and terracotta helps it do that. Typically $4 to $30.

The test, before you buy anything

How often does this plant want water? Fortnightly or less often means it wants to dry out, and terracotta helps it do that. Weekly or more often means terracotta works against you and you will be watering twice as much.

It depends

Depends on the plant. The right pot for anything drought-adapted, and the wrong pot for a fern. Neither material is better; they suit opposite plants.

Typical price $4–$30 depending on size. Hand-checked range, not a live price, last verified 2026-09-12. We hold no merchant relationships, so nothing here is a commission link.

What it actually is

Unglazed clay is porous, so water evaporates through the walls as well as the surface. A pot dries out roughly twice as fast as the same size in plastic.

What to avoid

Glazed ceramic is not terracotta — the glaze seals the pores and it behaves like plastic. And any pot without a drainage hole is the wrong pot regardless of material; that single feature kills more houseplants than any pest.

Species in this database that need it

These species go a fortnight or more between waterings, which is exactly the group that benefits from a pot that dries faster.
