When you pick between thanksgiving cacti deep or wide pots, go with wide and not too deep every time. Your plant has a root system that spreads out near the surface rather than diving down. A wide pot matches how those roots grow. It also keeps extra wet soil from sitting below your roots where it causes rot.
I learned this after moving one of my older plants from a tall nursery pot into a wide azalea-style container. The change showed up within one growing season. New stems came in thicker and greener than before. The plant set more buds that fall than it had in the two years prior. Finding the best pot for thanksgiving cactus growth made a bigger impact than I expected.
Your plant's wild roots explain why pot shape matters so much. Thanksgiving cacti are epiphytes that cling to tree branches and rocks in the Brazilian rainforest. Their roots spread sideways across surfaces. They grab moisture from rain and humid air around them. They never grew deep root systems because there's no deep soil on a tree branch. When you put those roots in a tall pot, the bottom inches of soil stay wet with nothing to dry them out.
The best pot for thanksgiving cactus health comes down to material too. Unglazed terracotta pulls moisture through its walls. This helps your soil dry out between waterings. It also gives your roots extra air flow. Plastic pots hold water longer and can lead to soggy soil if you water on a set day instead of checking with your finger first. For most growers, terracotta gives you the best control over your soil moisture.
For cactus pot size selection, the UMN Extension says your plant blooms best when it feels a bit cramped in its pot. Don't repot into something much bigger than what you have now. Pick a pot that is only 1 to 2 inches (2.5 to 5 cm) wider than your current container. Repot every three years or when you see roots poking through the drain holes. Going too big gives your roots extra soil that holds water they can't use.
Your pot must have drainage holes no matter what shape or material you choose. Without them, water pools at the bottom and creates the exact conditions that kill your roots fastest. If you find a pretty pot with no holes, use it as an outer shell. Place your plant in a smaller pot with drainage inside the outer one. Lift it out after each watering to dump any water that collects in the gap between the two pots.
