Coryphantha Ottonis

Coryphantha ottonis is a drought-tolerant plant that requires thorough watering only when the soil is completely dry. During the winter, water the plant once a week, and from spring to fall, increase watering to 1-2 times a week. It's best to use rainwater or distilled water to prevent soil compaction. Be careful to avoid wetting the stem, as this can lead to rot.

Coryphantha ottonis is a small, round cactus characterized by its tubercles and yellow flowers. To maintain its health, prune it in early spring by removing any dead stems, which can help prevent disease. Be sure to use sterilized tools to make careful, minimal cuts. This will improve airflow and light penetration, promoting healthy growth and reducing the risk of fungal infections.
