Potting peyote (Lophophora williamsii) properly is essential for keeping your cactus healthy, rot-free, and growing steadily. Peyote's growth slows when they outgrow their pot and old soil becomes compacted. They respond very well to being re-potted and usually gain vigor afterward.
Here are some important things to consider when potting a peyote cactus.
Choose the Right Pot
When it comes to peyote, terracotta pots are the best choice. Terracotta is porous, which allows water to evaporate from the soil quickly, preventing common issues caused by overwatering. The faster moisture can escape, the lower the chance of root rot or fungal infections.
Your pot should also contain a drainage hole. Without proper drainage, water can pool in the bottom and cause the roots of your cactus to rot.

Picking the Correct Pot Size
When choosing a pot, size matters. Oversized pots hold excess moisture which can cause issues. Here are some guidelines to picking the right sized pot.
-
Leave no more than an inch or two of space between the cactus and the edge of the pot.
-
Make sure there is around 2 inches of space at the bottom of the pot to accommodate root growth.
A properly sized pot gives the roots room to grow without holding excess soil that stays waterlogged for long periods.

Choosing the Right Soil
The best soil mix depends on the age of your cactus. Younger peyote seedlings do not retain water as efficiently as older plants, so they benefit from a slightly wetter environment. Mature peyote, on the other hand, can hold water very efficiently on their own and prefer faster-draining soil to prevent excess moisture from lingering around the roots.

How to Pot a Peyote Cactus
When you’re ready to pot your peyote:
-
Carefully remove the cactus from its old pot and gently loosen the soil from the roots.
-
Hold the cactus gently in place inside the new pot and fill soil in around the roots.
-
Lightly pack the soil down, making sure to cover only the roots and not any part of the cactus body. Damp soil that stays in contact with the cactus can cause fungal problems.
-
Adding a layer of small stones or coarse sand on top of the soil helps protect against bugs, reduces algae growth, and gives the pot a clean, finished look.
- Wait a few days to allow the roots to get over the shock of being transplanted before watering.

Conclusion
Proper moisture control and adequate root space help prevent common issues like rot and fungal problems. Taking the time to get these steps right ensures that your peyote will grow steadily and remain healthy for years to come.
