Terracotta versus plastic is about drying speed, not fashion. Clay is porous and loses water through the walls. Plastic and glazed ceramic hold moisture. This is not a repotting calendar; timing lives in repotting.
When Terracotta Wins
Snake plant, ZZ, cactus, and chronic overwaterers benefit. In a very dry home, or for calathea and ferns, clay may thirst every other day. Species notes: snake plant, ZZ plant.
When Plastic or Glaze Wins
Humidity lovers, windy balconies that crack dry clay at noon, and travelers who cannot let mix bone-dry in two days. Travel still needs its own plan: while away.
Drainage and Cachepots
A hole-less decorative pot is only a cover. The plant sits in a nursery pot inside it, and extra water must be dumped. Rocks are not a substitute for holes; see soil.
Size
Two to five centimeters wider, not twice as wide. An oversized pot is a wet soil mass with few roots. Log pot type in Jaliz because it changes watering gaps; water logic is in the watering guide.
Fabric and Metal Pots
Fabric pots dry very fast and may thirst daily on a windy balcony. Dark metal cooks the mix in sun; slip it inside a lighter cachepot or move it to shade. Heavy terracotta is harder for a pet to knock over.
Do Not Repot Only for Looks
If you only want a prettier cover, leave the plant in its nursery pot. Yanking it out tears roots. When it is truly rootbound, refresh the mix at the same time—do not drop the old spent soil into a bigger empty pot.
