Gymnocalycium calochlorum, commonly known as the Chin Cactus, is a small, globular cactus native to subtropical regions of South America. It is known for its attractive, ribbed body and striking flowers that range in color from white to pink. This succulent subshrub enters a dormancy period during the cooler months.
Gymnocalycium calochlorum thrives in bright, direct sunlight and prefers moderate temperatures. It should be watered sparingly, allowing the soil to dry out almost completely between waterings. This cactus enjoys low humidity and can adapt well to indoor environments.
Soil
This cactus prefers well-draining soil, such as a sandy or cactus mix. Good drainage is essential to prevent root rot. A mix of sand, perlite, and a small amount of organic matter works well.
Fertilizer
Fertilize Gymnocalycium calochlorum with a balanced cactus fertilizer, such as a 2-7-7 formula, during the growing season. Apply the fertilizer sparingly, about once a month, to avoid over-fertilization.
Repotting
Repot Gymnocalycium calochlorum every 2-3 years or when it outgrows its pot. Choose a slightly larger pot with good drainage. Handle the cactus carefully to avoid damaging its roots.
Propagation
Propagate Gymnocalycium calochlorum through offsets or seeds. Offsets can be removed and planted in a separate pot. Seeds should be sown in a well-draining soil mix and kept in a warm, bright location.
Pruning
Pruning is generally not required for Gymnocalycium calochlorum. Remove any dead or damaged parts to maintain the plant's health and appearance.
Toxicity
Gymnocalycium calochlorum is not toxic to pets or humans. However, it is always best to handle cacti with care to avoid injury from their spines.
