Coryphantha Longicornis

Coryphantha longicornis is a drought-tolerant plant that needs deep watering only when the soil has completely dried out. In the growing seasons, from spring to fall, water the plant once or twice a week. During the winter, reduce watering to about once a week. It's best to use rainwater or distilled water to prevent the soil from compacting, and be careful to avoid splashing water directly onto the stem.

Coryphantha longicornis has a globular shape and a spiny appearance. To maintain its health, prune it in early spring to remove dead parts, improve air circulation, and shape the plant. Be careful not to over-prune, as this can stress the plant. Always clean your tools before pruning to prevent infections. For best practices, consult horticultural resources.
