- Their genus name “Gymnocalycium” is the Greek for “naked calyx”. This description refers directly to their flower buds that bear no spines or hair.
- Chin cacti prefer bright, but indirect or filtered sunlight all-year-round. Too much extreme sunlight may damage your cacti, resulting in blooming failure.
- Unless you live in a warm region, these cacti are suitable only for growing them indoors. They need extra protection from extreme temperatures, especially frost conditions.
- If the temperatures drop below 50 °F (10 °C), Chin cacti must be placed under glass and cultivated with proper heat.
- Their potting soil must be well-draining and gritty, such as those commercial mixes that are specifically designed for cacti and succulents. They require fertilizers only when the growth is too slow.
- Gymnocalycium cacti have a shallow root system that is very sensitive to over-watering. Due to their tolerance of drought, it is always better to provide your cacti with less water than needed.
- There are no toxic effects reported for Chin cacti. They can be grown in the proximity of curious pets and children, however, their spines can be a bit dangerous.
