They have large conical tubercles 1 cm (0.39") in diameter with rounded areoles. They have 6-8 radial spines; the central spines (1 to 3) are yellowish and thunder gray with age. The yellow flowers with a red center are quite showy; they bloom in summer. Nipple Cactus is used to grow them in pots and planters; it's ideal for well-lit and ventilated interiors. Coryphantha sulcata can grow in direct or semi-shade sun exposure. The winter safety temperature is 4 ºC (39.2 ºF). The soil can be a commercial cactus substrate with 20% coarse sand or gravel. Always water moderately, waiting for the soil to dry completely. In autumn water every 20-25 days and do not water in winter. No need to fertilize or prune. If there is excess moisture, Coryphantha sulcata can be attacked by fungi or mealybugs, especially on the roots. Nipple Cactus propagates easily by seeds sown in spring or by rooting suckers. |
